Do You REALLY Understand Your Car?

Traditionally, the predominantly male operators of any form of transport craft confer a female personality to their vehicles. Down at a south coast yachting marina recently, I heard a proud owner boasting to a friend, saying “She’s truly beautiful”.

Pilots, including me, refer to their aircraft as “She”. “She flies nicely”, or “She doesn’t like being thrown about”, “She needs a touch of power when rounding out to land”.

Who could argue that She is beautiful. Supermarine Spitfire showing her elegance. Image courtesy Airwolfhound under CCA SA 2.0

It’s the same with cars, and it’s common to hear people, including women, referring to their cars as “She”. Before I get angry comments from my lady readers – yes, I am aware that many women own male cars, some that I know even name them.

The tradition of referring to a vessel as “She” goes back to ancient times. Nowadays, people may consider that this is somehow sexist, and objectifies women.

I prefer to believe that it’s more fundamental than that. Our early mariners were a superstitious bunch, and believed that the ship in which they sailed would offer protection and guidance, in much the same way that a mother or goddess would.

I refer to my aircraft as a “She”, as in my eyes she is elegant, pleasing to the eye, and demands to be treated with respect.

Today, there appears to be another reason.

Now, be honest. How many of you chaps out there believe that you don’t understand the woman in your life? How many long-suffering ladies out there are stupefied with their blokes’ methods and logic?

I have been happily with SWMBO for over three decades, but there are times when I am truly and utterly baffled by her. I know for sure that she experiences the same sense of bewilderment with my behaviour.

You may be wondering where this is going, but stay with me, dear reader.

If, like me, you own and operate, say, a five-year-old car, it will be fitted with some basic driver assistance systems. My car has rear parking sensors and steerable headlights. That’s it. Nothing fancy. It has standard Cruise Control, and an anti-lock braking system, like the one fitted to my previous 2002 Skoda Octavia.

If you decide to invest in a new car today, be prepared to be a little baffled by its behaviour and systems. (New cars are definitely female!).

In a previous article, I mentioned the Automated Driver Assistance Systems (ADAS) that are fitted to modern vehicles.

It’s likely your new pride and joy will be fitted with Adaptive Cruise Control, Lane Keeping Assistance, Blind Spot Monitoring, Autonomous Emergency Braking, Collision Avoidance Systems, Driver Alertness Monitoring, 360º Cameras and Intelligent Parking Aids.

To make the best use of these systems, drivers need to fully understand how they operate.

A few months ago, I decided to evaluate electric cars. I arranged to test drive cars provided by three of the main manufacturers, Kia, Nissan and MG.

Now, bearing in mind that all the vehicles I tested were fitted with some sophisticated systems, you would have thought that a full tutorial or some guidance would be offered by the salesmen before they let me loose on the road in one of their expensive cars.

Not quite.

All the dealers involved were more than happy to show me the boot space, and the clever stowages and storage areas, and gave me a very brief explanation of how to interpret the instruments and how to use the infotainment system, but not one discussed any elements of the ADAS in any real detail at all.

Luckily, I had conducted quite a bit of prior research, so I had a reasonable idea of how to change the level of regenerative braking, and how to use the different driving modes. However, there were many systems that, whilst I knew they were there, I had no idea how to configure them.

I have several friends who have recently purchased new cars, and when picking up their new vehicles, each one received no real training on how to use the systems correctly and effectively.

I have considered this, and it seems that this presents a bigger problem than I initially thought.

After collecting their new car from the dealer, proud owners will drive their new vehicle home, and maybe they will find the time to sit and wade through the Driver’s Handbook or Owner’s Manual. The onus is very much on them to gain understanding of the plethora of safety systems that their car is now loaded with.

More mature drivers, such as myself, will fall back on our “What’s to learn” mentality. We have grown up with cars fitted with few safety systems – maybe embryonic energy absorbing crumple zones, and collapsible steering columns. This is flawed thinking!


We had relatively unsophisticated in-car entertainment – maybe a push button radio, or a radio cassette player if we were driving a more luxurious model. I can remember being delighted with the fact that my first company car was fitted with a proper heated rear window and a fitted rear wash/wipe system.

Our cars were so simple that we just picked up the use of what systems we had as we drove. I think my biggest challenge was remembering on which side of the steering column the indicator control was located. The first few days of driving was always entertaining, with me switching the wipers on before making a turn!

So, for drivers of my generation, it is possible that we have a degree of complacency about the new systems, and maybe we don’t bother to sit down and read the book. (I do, but then I’m a bit geeky, having been a flight technical instructor for the past two decades!).

That may not be a good attitude to have these days.

In my world of professional aviation, we frequently refer to human factors, and even have training sessions on how simply being human affects the way in which a pilot interacts with an aeroplane.

There is a lot of automation on a modern aircraft flight deck. Autopilot, Auto Throttles, Flight Control Computers, Flight Management Computers, Automated Anti-Collision Systems, Ground Proximity Warning Systems, and Electronic Checklists and Diagnostics.

All of these systems must be understood, reacted to correctly, and effectively managed by the flight crew.

Despite high levels of safety-related automation, there are still incidents involving the crew falling asleep in flight, and flying past their destination. We still hear of aircraft being landed at the wrong airfields.

The same human factors will come into play in our increasingly automated cars.

There have been numerous reports of Tesla cars being involved in colliding with emergency vehicles whilst the Autopilot was engaged.

Most definitely human factors incidents, as the drivers simply assumed that the car was infallible, and therefore mentally disengaged and stopped supervising the on-board equipment.

A study by Massachusetts Institute of Technology (MIT) clearly showed that once drivers had engaged the Autopilot (or Adaptive Cruise Control) their focus of attention changed, and they spent much longer looking inside their cars, than paying attention to the road ahead.

Sometimes, drivers disengage to the point of falling asleep!

See this video of a Tesla driver, cruising and snoozing!

As a result, Nissan, at least, has incorporated what it calls an Intelligent Driver Alertness System. This system monitors the driver’s inputs to the steering wheel, and, using algorithms, it can predict the onset of tiredness and inattention. As arousal levels reduce, the chances of an accident increase, so the system suggests taking a break.

Screenshot of the Arousal Monitor. Wish my car would invite me for a coffee…

When I learned to drive, before making any manoeuvre, the mantra was “Mirror, Signal, Manoeuvre”. That has become ingrained behaviour, reinforced with 44 years of driving and in the region of 1.1 million miles travelled.

Wow! I have never worked that out before.

As a result, before lane changing, I always throw a quick glance in the door mirror. I have also ridden motorcycles for many years, so I can’t get out of the habit of looking over my shoulder as well.

If all is clear, I change lanes. Lots of people don’t do this and I have had to brake heavily to avoid being sideswiped on several occasions.

Interestingly, the Blind Spot Monitoring (BSM) systems being fitted to cars now are really good. You may be lucky enough to drive such a car, and, in many cases, the door mirror contains an indicator that turns amber when another vehicle intrudes into the safety zone, and turn red if a collision would result in the driver changing lanes.

Another piece of research studied the rates of lane-changing accidents across 26 US States. It found that accidents causing an injury were reduced by 23% in vehicles fitted with BSM systems.

If every US vehicle in 2015 had been fitted with BSM, it is estimated that 50,000 accidents and 16,000 injuries could have been avoided!

The other aspect of Blind Spot Monitoring is that used when parking or reversing. Now, I use all three mirrors, even though my car has a rudimentary parking aid that sounds a tone with increasing frequency as I reverse closer to a solid object – including a person, although I have never tried this.

Now, a further study has shown that the drivers of cars fitted with rear view cameras and sensors do not look to the sides of their vehicle before commencing reversing manoeuvres

Surprisingly, the use of rear-view monitoring cameras only reduced accidents involving “reversing into or over something” (maybe a person??) by 17%.

Still, a 17% reduction, is better than no reduction at all.

So, it all boils down to training and gaining an understanding of the equipment fitted to our cars.

I decided to check what the UK Driving Syllabus includes for cars and light vans (Class B Vehicles).

What I found was of interest.

As the document is undated, but is on the government’s assets publishing service site, as at October 2021, I assume it is a current piece of guidance.

I quickly reviewed it, and found two main concerns.

Firstly, it only mentions one Automatic Driver Assistance System, and that is Cruise Control.

Secondly, it focuses totally on driving a fossil fuel-powered vehicle.

Not a single mention of electric cars.

I do understand that they haven’t been around for very long – I mean, the Nissan Leaf has only been on the road since 2010, and what’s eleven years when you are setting the standards for people to learn to drive?

Sarcasm aside, there must be a need to teach new generations of drivers about the features, advantages and benefits of their vehicle’s on-board safety systems.

Maybe they should also be teaching students about the limitations of both those very same on-board systems, and their limitations as a human being.

You decide…

Go Well.

I Don’t Want to Eat My Vegetables is No Longer a Valid Excuse!

I leaned back in my chair with a feeling of contentment. SWMBO and I were sitting in the snug of one of our nearby village pubs, and I was now comfortably replete after noshing an exceptionally large Sunday Roast lunch. 

Ahhh. Sunday Lunch in a comfy local pub

This pub is renowned locally for its excellent food, well-kept ales, and quaint, comfy surroundings. The staff, all of whom were youngsters, were polite, attentive, and friendly.

Additionally, I had other reasons for using this pub. They have a policy of only using locally-sourced ingredients for all of their menu items. So, my roast beef was from a breeding butchery near Southampton, the vegetables were from a local farm, and the guest beers that I chose were from either the triple fff* brewery, based in Alton, or the Hepworth brewery in Pulborough, just across the county border in West Sussex. 

I am currently trying to persuade them to stock some of the really good ales made by the Firebird Brewery in Rudgwick, also in West Sussex.

I really like the idea of supporting local business, and helping to reduce my food miles, and my personal carbon footprint.

I was stuffed full. Yet the side dishes containing more vegetables and condiments and sauces were also still stuffed full, despite SWMBO and I laying into them with such gusto. I felt quite guilty about this, and knew that I was wasting perfectly good food. 

Not the Sunday Roast in question, but you get my point? Serving for one – plus sides!

In my rural area, the waste wouldn’t be quite such a problem, as some of it would probably go back into the farming system to be used as animal feed, but in towns and cities, this would all go straight into landfill.

I wondered to what extent we as a nation were wasting.

What I discovered was truly staggering.

In the UK alone, we waste approximately 10 million tonnes of perfectly useable food every year! Alarmingly, less than 1% of that is recycled in any meaningful way. 

Food – Just chucked into a skip, and left to rot before going to landfill

At the top of our “oh, just chuck it out” list was bread, with 900,000 tonnes wasted each year – that’s about 24 million slices that are sent to landfill. A lot of sandwiches, by anybody’s standard.

Add that to 5.8 million potatoes, and a huge volume of other vegetables and fruits, and it’s easy to see that we have a serious problem.

According to research conducted by the University of Edinburgh, about 33% of farm produce is wasted for aesthetic reasons. Supermarkets usually have contractual requirements for their vegetables and fruit, that specify minimum sizes, dimensions, weights, and appearance. 

This is driven by their perceptions on customer requirements, but, to be honest, the shape of my carrots, or a blemish on the skin of an apple aren’t overly high on my list of priorities. 


As a side issue, I have never once been canvassed for my opinions by any supermarket chain. 

Ever.

A third of all UK-grown, perfectly edible fruits and vegetables are rejected by our supermarket buyers for not meeting their specifications, and so they are wasted. They are probably just ploughed back into the land – and all this in a country where we now run food banks for those who are in desperate need.

This MUST change. The global food system produces about 25% – 30% of global greenhouse gases (GHGs), and agricultural supply chains use up to 70% of our freshwater reserves. Every tonne of food waste that goes to landfill sites will generate about 4.2 tonnes of GHGs. We must grow less and waste less.

But I digress. So, back to my sumptuous pub meal.

The hospitality industry wastes over a million tonnes of food because of providing over-generous portions. This is a tricky issue to address.

The corporate mindset seems to be that customer satisfaction is better served by plating up too large a portion and having some waste, rather than serving a portion that is perceived by the customer as being too small. 

Maybe a mental reset is required. The hospitality sector, pubs, bistros, restaurants etc., should start serving smaller portions, and tell customers that if they would like more side orders of vegetables and sauces, then they may ask for them free of charge.

So far, most that I have written is related to commercial food waste. Now have a think about the amount of food that you personally waste in your own homes.

For every 13 million tonnes of food waste generated, 7 million tonnes is wasted by people like you and I!

That is the equivalent of throwing away one full bag of groceries in every five bags with which you leave the supermarket!

Various initiatives have been set up by several charities, such as Feedback Global’s “The Pig Idea”, which attempts to change the law preventing waste food products from being fed to pigs. 

This law was originally passed to prevent contaminated edible waste from entering the food chain for pigs, which was thought to have caused an outbreak of Foot and Mouth disease. 

This was enshrined into EU law in 2002, but now that the UK has left federal Europe, it is possible for the UK Government to consider rescinding this law, subject to animal welfare standards being maintained to ensure the quality of any food waste to be fed to pigs.

Should this happen, the UK could simply revert to the centuries-old practice of feeding waste food to pigs.

A World War 2 Poster, urging the public to save food waste to feed pigs.

The food waste generated by the food manufacturing, catering and retail sectors (which would normally be destined for landfill) could potentially be reduced by about 2.5 million tonnes per year – a drop of 20%.

This is staggering!

The United Nations has stated that if all farmers globally were to feed their livestock on waste food and agricultural by-products, then enough grain could be liberated from the system to feed an estimated 3 billion people.

Supermarkets are also responsible for a lot of food waste at the opposite end of the process. Not only do they reject perfectly edible foodstuffs at the farm, but they also waste perfectly edible food that they over-order, and then just can’t sell!

We have all seen it. Yellow labels on food that is “out of date” being sold at heavy discounts. Like me, you have probably taken advantage of some low prices for food that is at the end of its shelf life.

Good Deals are often to be had, if you are willing to eat expiring food on the day you buy it!

Sadly, a lot of yellow-labelled goods remain unsold, and are therefore thrown into the skip (I have watched this happen at a local supermarket), destined for landfill somewhere.

This is a sad situation, especially as food poverty affects 8% of the UK population, some 5 million people.

To put this into perspective, my dear old Mum, who is in her nineties, volunteers at her local church, and as well as working in the café on a regular basis, she is also involved in the Church’s food bank. 

The food bank, like so many others, collects food and then distributes it to those who are in need. Having grown up during the Blitz, and the privations of rationing during World War Two (and afterwards – rationing didn’t end in the UK until July 1954) she hates waste of any kind, and always tries to live sustainably, well before such a word entered our vocabularies.

A Typical Weekly Ration for an Adult in 1940. 4 Ounces is 115 grams and 3 pints is about 1.7 litres

It still shocks her when she hears about waste of any kind, but she is a product of her generation, and some things are never forgotten.

There is hope though…

There are some wonderful charities that try to save food waste, and help those most in need of support.

Take The Felix Project. They collect surplus food, including vegetables, fruit, dairy produce, and meats, from food manufacturers, farms, supermarkets, and restaurants, and distribute it to those most in need. 

Then there is FareShare, which was started 27 years ago in 1994, as a joint venture between the UK Homeless charity, Crisis, and Sainsburys the supermarket chain.

Originally called Crisis FareShare, the charity collects and redistributes food to over 1,000 UK charities, and has partnerships with Tesco, Asda, and the Trussell Trust (which support the UK’s network of Food Banks). 

The “Feed People First” campaign that it ran in 2018 tried to ensure that it wouldn’t cost the food industry more to donate their surplus edible products to charities, than it would cost them to send it to landfill or animal feed manufacturers. 

By the end of 2018, the UK Government had committed to providing funding of £15 million to enable business to divert its surplus foodstuffs to charity.

Since it was started, FareShare has provided 236.8 million meals all of which were donated to people in need via a network of frontline charities. This resulted in savings to the voluntary sector (assuming they would have had to buy the same amount of food and drink) of about £180 million!

This is a fabulous achievement, but it still highlights a vast mismatch between food supply and demand – there is such a large surplus! It also shows that our society is broken in a sad way, when people living in a supposedly civilised country are suffering food poverty, despite our very generous welfare state.

They alone are responsible for saving tonnes of waste every year, whilst reducing human misery at the same time.

As climate change strengthens its grip on our world, we will have to make some serious changes. This is not only at a global and state level. This is also at local level.

I am not a great horticulturalist, and have little interest in growing things, but I think that in future more families will have to grow some of their own foods to reduce the need for intensive farming and food transportation. Maybe misshapen vegetables and blemished fruit will be more prevalent. 

In fact, Morrisons supermarkets have proven that even ugly produce is nutritious, edible, and has value.

Morrisons leads the way…

There is an alternative though, if, like me, you are a lousy gardener.

How about not only reducing waste for landfill, but also reducing GHGs, and saving money in the long run?

This is where a small, self-contained domestic biodigester plant comes into its own.

Biodigesters are designed to capture the methane given off by decomposing organic matter. 

A Typical Domestic Biodigester

For most people, organic matter would be food scraps including vegetables, fruit, meat, fish, dairy waste, cooking oils, pips, nuts, and bread.  Some folks may operate smallholdings, and may therefore benefit further by enabling a certain amount of manure from livestock to be used. 

For the truly environmentally-conscious, biogas lavatories are on the market that enable human waste to be processed as well. 

A Biodigester Toilet. Waste not Want not? https://www.homebiogas.com/product/bio-toilet-kit/

Biodigesters consist of a simple tank, which may be made of hard plastic, or out of very strong PVC sheeting. The waste organic products are simply placed into the tank, and within a short period of time, helpful, friendly bacteria will start breaking down the material.

There are two main by-products of the process. One is a good source of methane gas, and the other is liquid fertiliser.

The gas generation is simple, natural, and ecologically friendly, and the methane gas output may be used to operate a cooker. Once up and running, a typical biodigester will produce enough methane for two hours of cooking per day.

The slurry that may be drained off at the end of the process is full of nutrients that are essential for plant health, and are odourless and non-toxic.

I would add a word of caution here.  If you do decide to install a biogas lavatory, and use human waste, then you can’t use the by-product as fertiliser, and it must be treated as sewage and compliance with disposal regulations is essential. However, you can still tap off the methane!

So, maybe it’s time to buy less food, and to encourage our supermarkets to be less restrictive when specifying the acceptable standards for fruit, vegetables, and other produce.

Even reluctant gardeners should have a go. It’s possible to grow beans, peppers, potatoes and tomatoes in pots – even on a small balcony. Every little helps.

If you have a larger garden, maybe invest in a biodigester, and reduce your reliance on mains gas. You probably won’t generate enough gas to run your central heating, but you will be cutting down your GHG footprint.

I guess some of the answer lies in our own hands.

You decide.

Go Well…

The Wonderful World of Three-Dimensional Printing

I started work in 1975, as an apprentice communications engineer. During that wonderful autumn, I spent my time happily cruising around the local area with my supervising engineer, learning the art of installing and repairing telephones to residential addresses.

In the sleepy West Sussex town of East Grinstead (which was reasonably affluent), and the surrounding villages, many of the houses were large, and a number of our calls were to fit extension phones, extension bells or small House Exchange Systems.

House Exchange Telephone, circa 1970

Several customers worked from home, and their business needs in terms of equipment were relatively simple. Most had a second telephone line, and extension phones running from each. Some had a Telex machine, and some even had a very basic facsimile machine.

A good old fashioned Telex machine, circa 1970

No computers – all documents were created using typewriters, and I saw anything from a basic “sit up and beg” manual machine through to upmarket IBM “golf ball” typewriters.

IBM Selectric Electric Golfball Typewriter

It may appear strange to think that a home office could be so simple.

Surrounded by high tech, virtually every modern home has equipment that would make a 1975 businessman green with envy.

Inkjet printers that deliver reasonable quality may be bought in your local supermarket for under £100, and a home computer (with a massive 1 Terabyte of memory) will cost only £279.00 from PC World! Wi-Fi connectivity, and the ability to stream feature films in high definition is now commonplace.

My first printer was a Canon Bubble Jet printer, which occupied a corner of my desk. It was hard wired to my very basic desktop PC.

My latest set up is a full colour laser printer, which is attached to my home network by Wi-Fi, meaning that I can send a print request from my iPhone or iPad from anywhere in the house. It also has its own email address, so I can even send a document to be printed from anywhere in the world – not that I see much demand for this feature.

Laser printers used to cost thousands. They can now be obtained for a few hundred pounds.

Advances in software and computer processing, and a good deal of lateral thinking has enabled the development of three-dimensional printers.

In a previous article, “What do Mars and Bicycles Have in Common?” I asked whether science fact followed science fiction, or vice versa.

One of the original “Pulp Sci-Fi” magazines that my dear old Dad used to read, and give to me… 2/6d (12.5p)

It seems that in the case of three-dimensional printing, fact followed fiction.

The first documented reference to three-dimensional printing, (as far as I can prove) was made in the Sci-Fi story entitled “Tools of the Trade”, written by Raymond F Jones, and published in the November 1950 edition of Astounding Science Fiction. In the story, the author describes 3d printing as molecular spraying, but the principle was similar to what we now commonly refer to as 3D Printing.

During the early 1970s, a patent was filed by Johannes F Gottwald which described the principles and processes of 3D printing using liquid metals to form reusable structures, however, the technology and materials to develop the concept was unavailable.

It wasn’t until the 1980s, that the concept of 3D printing was seriously considered, and a number of early prototypes were under development from different designers and printer manufacturers.

As the technology was in its infancy, costs were very high – a basic 3D printer in the 80s would have cost upwards of 300,000 US$ (£217,000). In today’s money that would be in the region of 742,000 US$ (£539,000) – so not a realistic proposition for a home office.

By 1993, however, 3D printers using inkjets that sprayed liquid polymers were being manufactured, and by the 2000s, the technology was being developed and refined, and industrial applications were launched that enabled metals to be printed.

Think for a moment, about the way that many metal items are manufactured. Molten metal may be poured into a mould, and the resulting casting must be machined to create the shape of the part required. This is normally performed by using lathes, milling machines under computer control, from a computer-produced 3D design. (CAD/CAM – Computer Aided Design/Computer Aided Manufacturing).

This may be referred to as subtractive manufacturing, where unrequired material is machined away, leaving the part completed. Whilst the waste product may be recycled, this takes effort, and incurs cost.

On the other hand, using a 3D printer to produce a part, say an engine mounting bracket for a car, is an additive manufacturing process, where the part is created from nothing, and built up in the correct shape, layer by layer.

No waste, and incredibly flexible, the 3D printing process allows complex shapes to be created in one hit, rather than a number of different milling machine processes.

3D printing is rapidly penetrating all sorts of new markets, some of which may surprise you.

How about 3D printed food?

Sound crazy?

Maybe not – several companies have developed 3D printers that print Vegan “Steaks” using vegetable proteins. If a mass-produced artificial steak has the same texture, taste and appearance as an animal steak, then many people may switch to the alternative, which may be better for personal health in terms of eating less red meats.

From a sustainability perspective, globally, livestock produce 14.5% of climate change gases, so if meat consumption may be reduced, then there would be a proportionate reduction in intensively farmed cattle.

A 3D food printer which uses plant proteins as ink, and mimicks the texture and taste of meat….https://en.wikipedia.org/wiki/Giuseppe_Scionti

Would I try one?

Yes, without a doubt, and if they truly were a realistic alternative, and didn’t taste like Linda McCartney’s sausages, then I would no doubt enjoy the experience.

What else then?

How about using a 3D printer to build a house? Already, large scale 3D printers exist that extrude concrete, and 3D house are now being built as new developments, particularly in the USA.

This is quite groundbreaking, and an exciting development. Printed homes can be simply built in a fraction of the time that a conventional house takes. 3D printers can not only build floors, and walls, but can precisely extrude integrated channels for utilities, and mould ducting for air conditioning and electrical services.

A Concrete 3D printer constructing the walls of a building. How cool is that?

They also require far less labour to construct and are considerably cheaper than a conventional home of the same size.

The medical industry is also interested in 3D printing. Imagine being able to print a tablet which contains multiple medications, custom built for each patient. Instead of taking several tablets, a single multi-purpose pill could control a variety of medical conditions.

Imagine constructing an artificial heart, made of medical proteins and stem cells to recreate an exact replica of the patient’s original?

Prosthetic limbs printed quickly that precisely match a patient’s physiology!

Severely burnt individuals treated by repairing damage using artificial skin contoured and printed using a 3D printer delivering layers of bio-ink…

Science fiction?

No – Science Now!

Carnegie Mellon University (Pittsburgh USA) have printed a 100% accurate replica human heart, which exhibits the same levels of elasticity as human heart tissue. Only as a pilot project so far, but this technology can and will take off.

So, from the humble inkjet printer for bashing out a letter to Great Aunt Maud, to printing a three-bedroom house, 3D printing is here to stay.

Thank goodness for technology, eh?

Go Well…

What Do Mars and Bicycles Have in Common?

It’s a lovely day.

The sky outside is an impossibly brilliant blue, with just the occasional cloud to add texture and remind me that nature is hard at work, even if I am not.

This is an absolutely perfect day for flying. Definitely VMC (For my non-aviation friends and readers, that is Visual Meteorological Conditions, meaning that navigating and staying in control of the aircraft is performed by looking out of the windscreen – rather than flying in cloud or above the cloud, thereby having to fly by using the aircraft instruments, known as Instrument Meteorological Conditions).

The perfect day for a fifteen minute trundle over to the airstrip, to pull my aircraft from the hangar. A quick but thorough pre-flight inspection, and then away up into the sky, to meander through the air, with no particular place to go.

Maybe a leisurely buzz south to the coast, then east to Beachy Head, and then back over the sunlit rolling chalk and downlands that make up large swathes of Sussex and Hampshire.

So, why then, am I sitting here in my den, hammering an article into my keyboard.

Well, for one thing, my aeroplane is currently being reassembled after a major rebuild. It’s sitting forlornly in the gloom of the hangar, its wings rigged, and its engine and systems all fitted. However, with no flight control surfaces rigged, she might as well be a boat.

Fully rigged, engine and systems up and running – but no flight controls…

Secondly, I am awaiting the arrival of the technician from Autoglass to change the windscreen on my car.

Travelling back home from work one afternoon, I thought that I had come under machine-gun attack, and the volley of stones that hit the screen might as well have been real bullets, as they plunged deep into the laminated glass, and with a noise like a pistol shot, three long cracks propagated across the screen.

A short phone call to my insurers and £75.00 lighter, and the windscreen would be fixed. It appeared that as I had previously had two chips repaired, this would be a brand new screen.

Well, I was expecting to have to make an appointment to drop the car off at a repair station, but no, it would be changed on my drive, and all in about an hour.

So, staying with the vehicle theme, some of you may have read my previous article on the levels of pollution that is caused by the interaction of car tyres on roads?

No?

It may be worth a read if you are interested in sustainability, climate change and pollution.

Vehicle tyres degrade with use, and the erosion of the tread causes the release of micro-particles that wash into waterways, and ultimately into the seas and oceans.

So, a new piece of space-age technology caught my eye.

My first exposure to NASA[1] was as a barely-ten-year-old boy watching the launch of Apollo 11 on the 16th of July 1969, and subsequently watching recorded footage of the lunar landing on school TV on Monday 21st July.

To say that I was awestruck was an understatement.  Subsequently I couldn’t read enough about space, and became an avid reader of the science fiction pulp magazines such as Astounding Science Fiction and Amazing Stories that my dear old Dad used to buy from the secondhand bookstall not far from the tube station.

I think that by the time I was 13, I had the complete works of the mighty Isaac Asimov on my bookshelves, and was familiar with all of the Sci-Fi greats; Arthur C Clarke, Robert Heinlein and Philip K Dick.

A few days before the launch of Apollo 11, the BBC aired it’s first episode of Star Trek, and I had become a fan almost instantly.

The Crew of NC-1701 Starship Enterprise – Star Trek the Original Series

And I have been a real fan of quality science fiction (not to be confused with science fantasy such as the Marvel Superheroes) ever since.

There has always been, however, a blurring of the lines between science fiction, and science fact. Which drives which?

In Star Trek, (the original series) we saw Captain Kirk being presented with what looks like an iPad tablet for him to sign. Uhura, the Comms Officer wears what looks like an ancestor to a Bluetooth earpiece, and Motorola designed a flip phone that looked suspiciously like a Star Trek communicator.

I have to admit, that I am REALLY looking forward to using a dematerialisation transporter. Imagine just setting the co-ordinates of a friend’s house in California, and hitting the button and arriving microseconds later.

A universal replicator that ends poverty, and makes the use of money totally redundant…?

I digress…

So, it seems that Science Fact is now about to follow what was Science Fiction up until a few decades ago.

The continuing exploration of Mars has been conducted to a great extent by the Mars Rover vehicles, which have been sedately pottering over the Martian landscape since 1997. Kitted out with sensors, cameras and communications equipment these vehicles have been surveying our nearest planetary neighbour.

In order to traverse the hostile terrain, the current rover, Perseverance, is equipped with six 52.5cm (20.7 inch) wheels made from aluminium and springy titanium spokes. The wheels are fitted with cleats for additional traction.

Well…

It seems that the NASA-developed tyre technology may be coming to a vehicle near you – well, initially, a bicycle near you!

NASA – Not just a Space Agency! Designers, Developers and Scientists

These highly advanced tyres are designed by the SMART (Shape Memory Alloy Radial Technology) Tire company, and manufactured by NASA using a highly elastic material called NiTinol+.

Virtually all elastic materials will stretch, and then they may almost revert back to their previous shape and strength. Most will lose their resilience and potency – think of a well-used bungee strap.

The clever thing about the metal alloy used in the construction of Perseverance’s wheels is that it actually changes its molecular composition when it is flexed or distorted. Once no longer subjected to any loads, the material simply returns to its prior profile, and the molecules are rearranged to their previous composition.

Tyres constructed from this material would no longer need to have inner tubes, or be inflated with air – no more punctures, less weight, and the added strength of Titanium.

The outer surface of the “tyre” may be coated with a highly resilient synthetic rubber called Polyurethanium.

The robust nature of the tyre combination means that a SMART tyre will probably exceed the life of the vehicle to which it is fitted! There will be no risks of punctures, and deflations, no need to use sealants or carry a spare wheel.

In comparison to conventional steel, this new alloy, known as METL, is thirty times quicker to recover to its original profile. This made it ideal for use in the hostile environment and rugged terrain of Mars.

Now the good news!

These revolutionary tyres are about to be launched – initially for bicycles, which will enable further development to be carried out for heavier vehicles.

SMART Tires has already collaborated with the Micro-mobility scooter provider, Spin (owned by the Ford Motor Company) to develop tyres for electric scooters.

Currently, this is a small-scale project, but in due course, it will become a primary challenge for the $250 billion global tyre industry to adapt to and deliver. This will be driven, in part, by the ever more urgent need to reduce emissions of any kind.

SMART Tires aims to launch their range of tyres to the cycling community by 2022, and once in full production, will no doubt start developing wheel/tyre units for the automobile and motorcycle industries.

I imagine that the launch range of bike tyres will be expensive initially, and will appeal to only the upper echelons of competition cyclists, but the economy of scale will undoubtedly reduce prices to the level where they may be bought in your local high street bicycle shop.

So, in the words of Captain Jean-Luc Picard…

“Make it so!”

Well, Maybe buy one of these after I have bought the tyres! If I have any cash left!

Power Generating Flooring? What a load of Rot…

I walked into my den, clutching a fresh cup of tea, ready to start writing a new article. The squeaky floorboard near the door irritated me somewhat, as SWMB and I had taken every effort (as did our builder) to ensure that the wooden planks didn’t squeak as we walked around the house.

This plan worked well for the first few months, but gradually, the floor and stairs conspired against us, and began to creak as we walked around the house.

In some of the rooms, we managed to inject a resin compound to stop the slight movements, which is accomplished by drilling two small holes into the planks, and squiring the goo in under pressure.

Two tiny holes to stop a squeak… Photo Mark Charlwood©

This, again, worked for a while, until the creaks started coming back – and just when I thought that it was safe…

I personally don’t mind a few little creaks and squeaks, as it adds character to the place.

Squeaks and creaking floorboards happen as a result of the wood settling down, and as it ages, as all natural products do, it flexes more readily, and allows each plank to move slightly against adjoining planks, or shift slightly upon the joist to which it is fixed.

My mind wandered back to the old, edwardian house that I grew up in. Its’ uneven old floorboards used to grumble and groan, even when they were only supporting the weight of a poorly five-year-old.

That old house is etched into my brain indelibly.

When I was a kid, my Mum did all of the familys’ hot meals on a gas cooker, or in the gas oven. As a small boy, I well remember my Dad attempting to boil a kettle, striking match after match, and hearing him curse as the igniting gas finally engulfed his fingers, singing the hairs on his hand as he fumbled, without success to light a gas jet.

In the end the old boy arrived home one day with a small mechanical flint lighter, which was great news for Mum, as the shower of sparks lit the jet with ease.

Simple but effective – a simple spring steel flint lighter.

A few years later, Dad came home with his latest high-tech acquisition – a Piezo-electric butane lighter. This neat device contained a small reservoir of liquified butane gas, and a trigger that when pulled would generate a nice fat blue spark at the tip.

Easy and quick – and I still use one for fire lighting. Photo Mark Charlwood©

The resulting mini flame thrower was a teenage schoolboys’ delight.

I remember being intrigued with the way it worked.

The piezoelectric principle was discovered in the late 1880s. It was found that if certain materials were flexed, an electric current would be produced.

Over the years, this principle was developed, and has subsequently given us SONAR[1], inkjet printers, cigarette lighters, loudspeakers, motors such as those found on autofocus mechanisms in cameras and medical equipment.

Goodyear Tyres even considered using Piezoelectric technology to be used inside the carcase of a tyre that would generate electrical power every time the tyre flexed.

Why am I telling you about all this, when I normally write about new technology, sustainability and alternative energy?

There is a link, believe me.

So, back to sustainability.

Wood is a wonderful material for using in the construction of houses. If sourced responsibly, it is relatively inexpensive, reusable and recyclable. It also offers good levels of thermal and sound insulation, is relatively stable and may be machined fairly easily.

Timber stacked ready to be turned into a house

It is strong and resilient, and may be used in virtually every aspect of the construction of a house, from walls to roofing, and floors to cladding.

Whilst pottering about in the depths of the internet, I stumbled across a reason for welcoming potentially squeaky boards into your homes.

It seems that a team of researchers in Switzerland have established that timber, when flexed also exhibits the piezo electric effect.

Obviously, if it were to be possible to harvest the electrical output generated by people simply walking across a floor then this would assist in the battle to make homes carbon neutral.

The problem is that the types of wood used in flooring do not have enough flexibility to generate power effectively.

The research team discovered that by introducing a mild form of fungus (a white rot) the decaying process could be accelerated a little, and this in turn made the sample wood (balsa in the case of this early research) much more flexible – to the point that harvesting an electrical output became possible.

When a piece of wooden veneer was treated with the fungus, and then fitted with a piezo-electric converter, the plank would produce a voltage whenever it was trodden on!

The voltage was only small – just 0.85 Volts, and at a very low current, but the scientific conclusion is that the output could be scaled up.

Naturally, it’s likely that such a bio-engineered concept would only work over a large square area of floor, with a high traffic load, such as an office, auditorium, ballroom or gymnasium.

Harnessing nature and working with it may offer better long-term solutions to some of our global problems.

I guess the alternative is to incorporate piezoelectric sensors in my shoes, and charge my iPhone in my pocket?

Yes – Really! Walk 10,000 steps, get fit, and charge your phone!

Meanwhile, I will just accept that my floor is just sighing contentedly…

Go Well.

If You Think Humanity Is Stupid Now, Keep Polluting and See What Happens…

Climate change.

We have been hearing about it in the news almost every day, until it was supplanted by other issues. The run-up to BREXIT, the general election, floods, and now the Coronavirus pandemic have made us all temporarily dump the issue and public attention is now fully occupied with the control of the global pandemic.

The mainstream media have highlighted the drop in climate-change gases – a direct link to a significant reduction in both travel and manufacturing following global lockdown.

From a planetary perspective, the drop is not highly significant and as soon as lockdown finishes, we will probably revert to our old ways very quickly. 

Having said that, I am hopeful that state governments will use the opportunity to consolidate some of the steps that have been taken to enable the use of alternative means of transport – making that small reductions permanent. 

We have seen cities around the world banning vehicular traffic from city streets, together with enhancing cycle lanes and pedestrian routes, making it easier and cleaner to travel.

Electric Bicycles – the best of both worlds – and you can take them on the train!

This is nowhere near enough, but at least it is showing that people can get around large cities safely without using a car or public transport.

All the media focus revolves primarily around the ever-increasing levels of air pollution that are triggering climate change, rising sea levels and rising temperature.

There is, however, an interesting health issue that lurks in the sidelines.

As a species, we rely on breathing air, from which we extract oxygen, and then exhale CO2, together with other gases such as Nitrogen and Methane, and some organic compounds.

In order for our bodies to function correctly we rely on our lungs to absorb oxygen and exhale the COin the correct ratios. 

The composition of the air that we breathe is 78% Nitrogen, 21% Oxygen, and 1% Argon. There are also traces of CO2, and rare gases such as Xenon, Neon, Helium, Methane.

As we increase the levels of CO2 in the air, our lungs will be unable to exhale the surplus and this will be absorbed into the body, which will have an effect.

According to a recent study conducted by the University of Colorado in Boulder, The Colorado School of Public Health, and the University of Pennsylvania, evidence suggests that future levels of CO2 may severely impair our cognitive ability.

The study based its research on two scenarios; one, a world where human society reduces the amount of CO2 it releases into the atmosphere, and the other where we don’t – “business as usual.”

Alarmingly, even when we do reduce the amount of carbon dioxide that we release into the ecosystem, by the year 2100, individuals would still be exposed to elevated levels (by today’s standards) of CO2 leading to a 25% decrease in cognitive abilities.

The reduction in mental ability is caused by an increase in CO2 in the brain, a condition called Hypercapnia. which leads to a reduction in brain/blood oxygen (Hypoxemia).

The result is a reduction in brain activity, decreased levels of arousal and excitability. On top of this, it induces sleepiness, and anxiety, the result of which is an impact on our cognitive functions such as learning, memory, strategising and crisis management.

Lost Concentration…? Foggy Brain…? Maybe thats Air Pollution for you…Photo by Oladimeji Ajegbile on Pexels.com

This is easily understood. Who hasn’t been in a lecture room, classroom or meeting room, where our concentration wanders, and we get tired and disengaged. The result of excess CO2 released by a lot of individuals. The solution is normally to open a window to let in some fresh air.

But what if the air outside was not really fresh at all? 

A report in 2001 (Robertson) argued that even slightly elevated levels of CO2 (720 parts per million) could cause lowered pH in the blood (acidosis) leading to restlessness, mild hypertension and ultimately confusion.

The report concluded that if we continue with “business as usual”, flagrantly releasing megatons of COinto the atmosphere, by 2100 we could see our cognitive functions reduced by as much as 50%.

Unless we build on this virally-induced reduction in CO2 and continue to decrease global pollution, we may survive this.

If not, we, as a race, are doomed to become the joint recipients of the last-ever Darwin Awards.

Bill and George? Who?

Today should, by rights, be a good day for me to write an article.

Maybe words to titillate the senses; maybe to educate, entertain or inform? Or maybe an opportunity for me to be self-indulgent.

Why does today augur such good omens?

Well, for a start, it just happens to be the birthday of William Shakespeare, or so the historians think. The actual date of the bard’s birth is not recorded or documented, but his baptism was, and he was christened on 26th April 1564. It was normal to have baptisms three days after the birth, so I guess its a reasonable assumption.

Weirdly, William Shakespeare died on the 23rd April 1616. This is documented, so either way you look at it, this should be a good day for a struggling penman to bash out a few words.

Now, flashback to the early 1970s.

Confounding my father’s prediction that I would be an imbecile for the rest of my life, I did pass my eleven-plus exam, and made the cut to get into Grammar School.

A typical 11+ exam from 1968… Could a ten year old do these now?

English lessons with Mr Dobbins were dreary and dull, but at least he taught me the fundamentals of grammar, and spelling.

Even at that age, I was a voracious reader. My bedroom bookshelves housed the complete works of Issac Asimov (all read, I add), but I recall that I also dabbled with H G Wells, Jules Verne, E E “Doc” Smith and Arthur C Clarke.

Just one of the reasons why I love Science Fiction

However, nothing prepared me for the sheer, unadulterated hell of classes in English Literature.

Miss Briggs, my English Mistress, was a true hippie, complete with an Alice headband, long dresses and mauve tights. I think she knitted her own shoes.

But she was a nice soul, generous with her praise, and gentle with her frustrations at dealing with a totally disengaged class.

The english literature syllabus back then required that students were able to understand the context of the books studied, and could explain the use of metaphores, and allegories.

This meant that the works of the great writers were dismantled, sentence by sentence, line by line, chapter by chapter.

And then the probing questions and tests to establish our understanding…

“Mark, what did Shakespeare mean by his obscure use of the word and in this sentence.

After two years of dissecting Macbeth and Richard the Second, I was put off Shakespeare’s works completely,. So whilst I could (and still can) recite several speeches and soliluquies, I ended up leaving school with a deep seated loathing for Shakespeare, and a not much better opinion of the mediaeval writer Geoffrey Chaucer. Maybe this was a reaction against learning The Millers Tale and the Nun’s Priest’s Tale in Middle English.

What the hell were our educators thinking???? My old school friends, with whom I still meet regularly, all left school with the same feelings.

It was many years before I came into contact with the Bard again; I was in my mid twenties, and had joined my local drama group. After gaining confidence and appearing on stage in a lot of very minor bit parts, I was finally being offered more principle or leading roles.

One winter evening, I went to a meeting of the players, to discover that the next play we were producing would be A Midsummer Night Dream.

Would you like to see my Bottom?

My heart sank. Not Shakespeare…

Please…

However, I soon discovered that when read and performed as the great man intended it to be, it was truly joyous, and is a great piece of literature.

I have never managed to read any of his works as a book. I have watched and genuinely enjoyed some excellent performances of his work, so the cultural damage inflicted upon me as a kid have been repaired, but it has taken over four decades!

If they had required that I study Science Fiction, I would have probably passed my English Lit exam with an A+ rather than a C-.

The other thing of note about today’s date, is that it is Saint George’s Day.

Saint George on his charger…

For those that aren’t familiar with Saint George, let me briefly explain. St. George is the patron Saint of England. Not Britain. England.

The true history of St. George is lost in the mists of time, but he did exist. It appears from several accounts that he was a serving officer in the Roman army around 300AD. Legend has it that he killed a dragon that was slaughtering the residents of a local town. He was offered a monetary reward from the King, but refused to accept it, and donated it to the poor of the town.

This made him worthy of Sainthood.

There are accounts from 12th Century Genovese books that refer to Saint George’s colours being a red cross on a white background.

Other accounts tell of him fighting alongside the English Knights Templar during the crusades of the 12th Century.

In 1348 King Edward III of England incorporated the Cross of St. George into the English Royal Standard, and by the end of the 14th Century, St George was adopted as the Patron Saint of England, and the Protector of the Royal Family.

The English Royal Standard, circa 1348

It has been this way for centuries.

Now, the English seem to have a reputation as a self effacing race. We don’t normally go in for self agrandisement, prefering understatement to get by. That and the much publicised “Stiff Upper Lip”.

So, it’s our Patron Saint’s day today. We are in lockdown. So none of our pubs will be open for the discounted English Ale, cheap Cider, roast beef sandwiches and pork pies . There will be no give-away straw hats, or plastic flags. No Public Holiday.

But then, we don’t do that anyway.

COVID 19 – Lockdown and Walking with Nature

I’m sitting here in the early evening enjoying my back garden, listening to the birds as I mull over this article. My terrace is bathed in warm, golden sunlight, as Sol starts to dip majestically behind the trees lining the nature reserve.

I am so very fortunate. I have managed to make the right decisions – either by luck, intuititon, or skill, that have resulted in me living in a beautiful part of the UK. Or it could be SWMBO’s excellent judgement.

I don’t question SWMBO’s judgement – she is, after all, with me, so her decision making and judgement skills are refined.

I live in Hampshire which, like most of the UK, has a timeline of civilisation that extends 14,000 years into the past.

Roman Emperor Claudius invaded Britain in AD 43 and shortly thereafter (in the larger scale of things), Winchester became the County Town of Hampshire.

For those of you that are unfamiliar with the British concept of county towns – a county town was the ancient equivalent of of a capital city, but at county level. Traditionally, a county town is the most important or significant town in a county.

Winchester is not only the county town of Hampshire, but also a city in the truest sense of the definition.

In the UK, most people use the term “city” to describe any large town, but the status of a city was traditionally only given to towns that had a Cathedral – King Henry the Eighth establishing the first ones during his reign. To this day, the UK’s monarch has to grant city status to any town.

Winchester cathedral was consecrated in 1093, and is a wonderful old building, which seems to have history seeping out of its walls and emanating from its very fabric.

The opulence of Winchester Cathedral

Winchester is about 24 miles west of where I live. It is a beautiful old city. It is where the ancient English King, Alfred had his royal seat.

King Alfred the Great – Still watching for marauding Vikings…

The old part of the city, in which the ancient cathedral sits, is a maze of tiny cobbled streets and lanes.

Winchester City centre. Disney or Universal take note…

I digress.

The area in which I live is also historic. There has been a human settlement here at least since the 14th Century; the Roman army crossed the River Wey at Lindford, about 1 mile away, whilst en-route to battle in the west of the county in the early part of the the last millenium. The crossing over the local stream has been here since 1350, but the current bridge was refurbished in 2008.

So, we are in Lockdown.

According to Her Majesty’s Government (HMG), we are allowed to exercise once a day. So, this last Sunday, SWMBO and I decided that we would partake of some gentle exercise in the form a walk through the Deadwater Valley Nature Reserve.

It was a beautiful afternoon, with a light zephyr tousling the crowns of the trees as we left the house. A six minute walk up the hill took us to the entrance of the nature trail.

The trail is cool, the smell of damp sphagnum moss mixed with that wonderful, rich, loamy, peaty aroma. The sunlight pierced the canopy with spears of golden light, impaling the shy bluebells and forget-me-nots hiding on the floor of the woods.

Quiet – and with no risk of bears or vampires…

We continue wandering, sowly, drinking in the scents of the woodland. The information board informs me that this is a home to Stag Beetles, Slow Worms, Sparrowhawks, Red Admiral butterflies, Nuthatches and Goldfinches – together with the occassional Roe or Muncjac deer.

We plod on, hand in hand, humbled by the sheer abundance of plants, insects and wildlife.

The Deadwater Sream, slowly meandering its way towards the River Wey…

We see few people on the trail; those that we do are keen to ensure that we all comply with the two metre separation. Sometimes, we yield to walkers coming towards us, standing in the undergrowth so tha they may pass. Natural selection seems to ensure that next time we meet fellow walkers, they hold back for us to pass.

However, the social niceties are maintained, with many “good afternoons”. “please”, “thank you” and “have a good one” as we contine our walk.

The trail isn’t crowded by any means; we are in solitude for most of it – just us, walking, talking, laughing. Soaking up the atmosphere and enjoying nature.

Bluebells carpet the walk – just about everywhere. I love Spring – my favorite season

We continued on, walking generally north until we reached the exit point, where the new housing estate starts.

Not wanting to just return on the same route, we decide to wander through the small town suburbia and re-enter the reserve a little further down.

It’s a relief to leave the road once more, lined as it is, with high density housing, and populated with bus stops, garage blocks and parking bays.

We re-enter the reserve, skirting the sticky muddy morass near the stile, and test the waterproof capabilities of our footwear as we stride on through the silty puddles that surround the more glutinous mud.

Looking at the tracks in the earth, I immediately deduce that the trail is used by mountain bikers, hikers, walkers, children and dogs.

Eat your heart out Sherlock Holmes. Go back to your flat Hercule Poirot.

Whilst the nature reserve isn’t large, we have never visited before, so I was happy that I had a fully paid up account with the Ordnance Survey, and had access to excellent charts.

Using the app, we quickly planned how we would return to the end of the park nearest our home.

Our route back took us past a picturesque pond, which, according to the information board, was home to Toads, Frogs, Herons and Dragonflies.

The pond, basking in the sunshine, as it has done for over 100 years.

Sadly, we didn’t see any of them, but it has given me an excuse to come back again to check it out more regularly.

I would not necessarily have discovered this wonderful place if I hadn’t been on lockdown – so something good has come about as a result of COVID19.

My day today has been filled with catching up on various tasks around the house, so maybe tomorrow I will dig my bike out, and go and explore in a bit more detail.

A great way to do an hours exercise without having to go to the gym, which I find abhorrent at the best of times.

Go Well…

Coronavirus – The Catalyst for Global Change?

Unless you have been living on the Cook Islands for the last few months, you will have heard of Corona Virus, now known as COVID 19.

The virus is officially a global pandemic, and is now rampaging across every continent, leaving a trail of dead.

Here in the United Kingdom, we are in a state of national emergency, and state-sanctioned lockdown is in effect, with only absolutley essential journeys authorised. All retail shops except those selling essential supplies such as food, maedicines and perhaps bizzarely, alcohol are closed.

The London Underground has shut stations across its network, and passengers figures are plummeting.

Stations shut as a result of Coronavirus

Working at home has been the norm for many workers. As a result, the economy is in freefall, with the retail and hospitality sectors being worst hit. Clubs, pubs, cinemas, churches, sports centres, museums and public buildings are now all closed for the immediate future.

The aviation and maritime sectors have been quick to feel the impact of travel restrictions, and many airports are struggling as flights have become virtually non-existent, passenger traffic stagnated, and many airlines now trying to mitigate their losses by flying freight.

Flight Radar 24 – Screenshot showing flights in South East England. This was taken mid morning on the 13th April 2020. This airspace would normally be teeming with traffic, given that this is a Public Holiday in the UK.

Whilst the global shutdown is severely damaging both our manufacturing and financial economies, we are reaping some form of benefit; pollution levels have dropped across the planet, and air quality is improving.

Imagery from the Copernicus Programme’s Sentinel 5P satellite. The left hand image shows Nitrous Oxide pollution over France and Italy. Darker Red is higher levels of pollution. The right hand image shows how the levels and extent have reduced throughout the month of March 2020

It’s not just transport that contributes to atmospheric pollution – industrial and manufacturing activities have fallen across the UK and Europe as countries shutdown their economies to fight the coronavirus pandemic.

This shows that it is possible to stop climate change, but the societal costs are far too high to make this acceptable.

I do believe that when the virus is contained or burnt out, we will emerge from lockdown and social distancing as a changed society.

So, what may happen?

Many firms that up until recently were resistant to their employees working remotely will have seen that some of their “trust issues” have been proved to be unfounded and that staff have been as productive, if not more productive that when working at the office.

Bearing in mind the cost of office space, many companies may find the savings realised by using smaller premises make remote working desirable.

After a major pandemic such as this one, people may be far more cautious about personal hygeine, and become much more concerned to see that public areas are properly sanitised. This could have an effect on the practice of hot desking at work.

The travelling public will probably also need to see evidence that public transport is cleaned and sanitised far more regulalrly and effectively than currently.

The lack of public trust in the health security of public transport could trigger more car use, as people seek to protect themselves with more regularised self isolating. Even car sharing could become less popular as people choose not ot sit in close proximity with another individual on their commute.

Who can really say?

If thousands more people take up remote working, there may well be more economic pain ahead for public transport operators.

Railway and air journeys that used to be undertaken for business meetings may well now be conducted using video conferencing using internet platforms such as Skype for Business and Microsoft Teams.

Will our current level of communications network provision be sufficient to accommodate this?

Individuals that were reluctant to order shopping on-line, or use home delivery services prior to COVID 19 have now been using them out of necessity, and many of these people will now be sold on the advantages, leading to further decline of England’s high streets.

Individuals that were previously regular patrons of theatre and cinema will have become adept at streaming movies and watching “live” performances from the comfort of their own homes, using YouTube, Netflix or Amazon Prime.

The question is – will they return to the cinemas and thatres with quite the same degree of regularity as they did before?

It seems that the mainstream media have been focusing on the leisure and retail industries and whilst they do report on the struggle for our manufacturing industries, they do not highlight the underlying problems.

In the UK there is evidence that our contingency planning for a “Hard Brexit” triggered our government to closely examine our logisitcal supply chains with the involvement of the retail and distirbution industries, and this has surely helped ensure that truly essential items remained on the supermarket shelves, despite the media-induced panic buying.

The other aspect to this is the lack of resilience that our manufacturers have against supply chain failures.

Whilst numerous products are proudly made here in the UK, few are totally built here. Huge numbers of manufacturers import sub-assemblies, parts and components from overseas which are used to build their product.

The world’s biggest exporter, China, is, to all intents and purposes, the birthplace of COVID19, and also its primary exporter. The subsequent lockdown of the Chinese economy led to an abundance of British manufacturers struggling to obtain the raw materials, parts, components and sub-components needed to build and sell their own products..

This may result in a baseline realignment of our logisitical networks, and maybe re-initiate inward investment.

Who knows, we may see a slow transformation back into a manufacturing economy again.

This is a bit of a mixed bag then; at more localised levels the possible resulting drop in bus and train usage could lead to more cars on the road, each contributing to climate change. On the other hand, more people at home reduces traffic of any kind on the roads.

There are so many possible futures that could result from the aftermath of CV19, which only action at government level can establish.

This could be a great opportunity for each state to re-evaluate its’s strategies for handling pandemics, and may trigger new systems to increase the robustness of manufacturing bases.

Who knows, it may even give us the required impetus to design an improved model for society that will offer progress on controlling our nemesis of irreversible climate change.

backwards or forwards?

Tomorrow is the date at which the clocks go forwards by one hour, moving us instantly from Greenwich Mean Time (GMT) to British Summer Time (BST).

Correct today – but tomorrow?

This has been happening every year since the Summer Time Act was passed by Parliament in 1916, whilst the Great War was raging in Europe. Placing the clocks an hour ahead gave workers an extra hour of daylight in the evening, enabling greater productivity for the war machine.

After World War One the annual changes to the clocks continued ping-ponging back and forth between BST and GMT.

World War Two started in September 1939, and by 1941 the UK was on Double Summertime (DST). This was achieved by putting the clocks forward in spring 1940 and not putting them back to GMT at the end of Autumn. In spring 1941, the clocks were advanced by an hour again – giving even more daylight to aid productivity.

This went on until autumn 1947, when the clocks went back completely to GMT.

Despite a parliamentary enquiry conducted in the late 1950s, involving 180 organisations, which concluded that there was a slight preference to remain on GMT +1 throughout the year, Britain stayed with the system

Why am I telling you all this?

Well, its because I’m in two minds about this.

Research conducted by the University of Colorado (Boulder) has shown conclusively that the fatal car accident rate spikes by 6% during the working week following the clocks being moved forward into Daylight Saving Time (DST). As the research only studied fatal accidents, it may be reasonably assumed that the underlying rate for all accidents will increase.

A further study published by Vanderbilt University’s Medical Unit shows that there is a negative impact upon health during the transition from statndard time to daylight saving time.

The cumulative effects of Daylight Saving Time can lead to increasing risks of heat attacks and ischaemic strokes

It appears that its not just the biannual one hour difference interfereing with our “body clock” or Circadian Rhythm – but the cumulative effects of this misalignment which takes up about eight months of the year.

It is the actual process of changing rather than which time reference is followed.

The European Union (EU) has voted to end Daylight Saving Time in autumn 2021. States within the EU have the choice of making their last change on the final sunday of March, or the final sunday of October, depending on whether they wish to have their standard time based on summertime or wintertime. This would naturally accommodate preferences according to geographic location.

More time on my hands – Yes Please!

So – moving the clocks back and forward is bad for health, and bad for accident rates.

On the other hand, there is a big argument for doing something more radical.

This time tomorrow?

Lets stay on GMT+1 as our standard time.

Moving the clocks forward every spring, as we did in WW2, gives us effectively two hours more sunlight in the evening during summer, and one more hour of evening light in the winter.

Looking at this from an environmental perspective; extra light means less electrical demand for lighting in the summer, and during the winter months less demand for heat as well.

Research conducted by Cambridge University showed that an extra hour of sunlight every day during winter could save up to £485M ($604M US) annually.

A further benefit is a proportionate reduction in carbon emissions as well.

Now, lets think about trade. Disregarding Brexit, we still do a lot of trade with our neighbours in the EU. However, even the most western part of the continent is always an hour ahead of the UK, and eastern states such as Finland are two hours ahead.

This is an impediment to easy trade, so staying GMT+1 in winter, and GMT+2 in summer would keep us aligned with our european trading partners.

Tourism would also receive a big boost, with longer hours available when people are not working.

The Tourism Alliance estimated that an extra £3.5M ($435.9 US) of revenue would be generated in the UK as a result iof businesses staying open for longer. This would create an estimated 80,000 jobs.

Individuals would also gain about 235 hours of post-work daylight every year,

Now that’s got to be worth having!

What would people do with all of this extra daylight? Well., they would use the opportunity to play sports, visit parks and enjoy outdoor recreational activities.

This has a health benefit, as more people out exercising (Even if they are only walking or cycling to the pub!) means less people becoming unhealthy as a result of inactivity.

Human nature is such that we tend to stop outdoor activities when it gets dark. SImply readjusting our clocks so that “dark” coincides with “later” means we achieve more each day.

The extra hours of daylight could also reduce crime levels, as most criminals do like to do their “work” in the dark.

My opinion?

Well, I would like to use the old WW2 system of GMT+1/GMT+2. Ilike the idsea of an extra 235 useful hours every year. I like the idea of saving power and cutting emissions.

It does seem that on balance this could be the best option for business, the planet and us living on it.

You decide…

Go Well
