Thanks for that.

Note how that is a very swish website with lots of 'infrastructure'...


Personally, I don't like the look of that idea at all!...

A few of my immediate thoughts are:

  • Really, no planning permission needed?...
  • No regulations needed?...
  • What of safety/certification to ensure that:

    • Those devices do not damage or endanger the traffic;
    • That they remain benign even when unmaintained or abandoned;
    • Parts can never fly off to endanger traffic even in the worst conditions;
    • Are they crash safe?


  • Do they guarantee no dazzle factor under any conditions, even at night for a long line of them?
  • Really, they are not dangerously distracting?
  • Added driver fatigue due to miles of unnecessary additional motion distraction?
  • Additional spray and visibility hazard in rain and snow?
  • Increased noise?



And note that in the real world of physics, there is no such thing as a "free lunch"...

I strongly suspect that they will be stealing at least a proportion of the generated electricity from the fuel used to push the traffic past them that then causes them to spin... The passing traffic then suffers increased fuel usage.


Where do we get that lot checked up upon?

Stay safe folks!
Martin

Up, up and away.

Hydrogen-powered flights hitting California by 2024.

Hydrogen-powered short-distance passenger flights could soon be coming to California — paving the way to a future of clean-energy air travel.

Seattle-based aviation company ZeroAvia is set to start air tests of the Dornier 228, a 19-seat passenger plane the company has converted to run on a hydrogen-fueled powertrain, according to car-and-truck trade journal AutoEvolution.

Last year, ZeroAvia proved the propulsion system — which it calls HyperTruck — could work on the ground when the company used the technology to propel a 15-ton military truck.

ZeroAvia hopes to reach a 500-mile range for its regional aircraft, according to Bloomberg. But the company has bigger plans if it manages to get Federal Aviation Administration approval: A 40-80 seat hydrogen-powered airliner by 2026, according to AutoEvolution....

Why not break down several processes into 1?

Can this MIT metallurgist clean up copper production?

But will industry change their ways and take it up?

It's the balance between profit and law-enforcement penalties that counts.

When the business is big penalties don't even rise to pocket change.

Then the politicians aren't setting the penalties high enough (perhaps for obvious "I'll scratch your back if you scratch mine" reasons). Some of the newer financial misdemeanours are seeing potential penalties set at a significant percentage of global turnover, rather than profit: that should be big enough to be noticed.

It is worth noting that the penalty delivered by a court may not be the only one that hits a company. On occasion the public have delivered a much more painful one, product disloyalty, boycotts and so on all hit the bottom line. Then there's secondary and tertiary court cases that just keep rolling up at the door (as VAG are finding out years after the initial Dieselgate case).

Now here's a practical idea, gravity batteries.

Can gravity batteries solve our energy storage problems?

There is a riddle at the heart of the renewable energy revolution. When the wind blows, the sun shines, and the waves roll, there is abundant green power to be generated. But when skies darken and conditions are calm, what do we do?

The answer, today, is to ramp up conventional power production, supplying the grid by burning fossil fuels. It is a 20th Century solution to a 21st Century problem – one that sits in sharp contrast with plans for carbon neutrality.

A cleaner future will mean focusing on ever-larger lithium-ion batteries, some energy experts say. Others argue that green hydrogen is the world's best hope. And then there are those placing their bets not on chemistry, but the limitless force that surrounds us all: gravity.

"What goes up, must come down" – this is the immutable Newtonian logic underpinning gravity batteries. This new field of energy storage technology is remarkably simple in principle. When green energy is plentiful, use it to haul a colossal weight to a predetermined height. When renewables are limited, release the load, powering a generator with the downward gravitational pull.

A similar approach, "pumped hydro", accounts for more than 90% of the globe's current high capacity energy storage. Funnel water uphill using surplus power and then, when needed, channel it down through hydroelectric generators. It's a tried-and-tested system. But there are significant issues around scalability. Hydro projects are big and expensive with prohibitive capital costs, and they have exacting geographical requirements – vertiginous terrain and an abundance of water. If the world is to reach net-zero, it needs an energy storage system that can be situated almost anywhere, and at scale....

Now I wonder where this pair came up with this idea?

Recyclers see used glass bottles as key to easing worldwide sand shortage.

The funny thing is that we had amassed massive piles of recycled glass creating a huge storage problems here several years back and we have been using the stuff in just these fashions ever since.

After a 3 1/2-year-long test Japanese engineers reckon that it's now ready for commercial use.

Japan’s Big Boy Deep-Sea Turbine Will Harness the Power of Ocean Currents.

Japan is dropping a massive 330-ton turbine power generator onto the ocean floor just off the country’s coast in a bid to source theoretically limitless renewable energy.

Over the past decade, IHI Corporation has been developing “Kairyu,” a 100-kilowatt-class generator that can harness the power of ocean currents. In February, the Tokyo-based engineering firm successfully completed a 3 1/2-year-long test of the subsea turbine in the waters of southwestern Japan. You can expect to see it up-and-running sometime in the 2030s...

The great vegan diet ‘con’
Despite what the documentaries tell you, a plant-based lifestyle isn't better for your health and it certainly won't save the planet
Canola oil, yeast, acidity regulator, methyl­cellulose, corn oil thickener, starch, gelling agent. “Hmm, I don’t like agents in my food,” says Jayne Buxton.
We’re in the refrigerator aisle of a well-known, high-end health-food supermarket in Richmond, London, reading the backs of packets of vegan ­sausages, burgers et al. As far as vegan products go, we’re dining at the Ritz.
Pastrami-style slices, scrambled tofu, vegan chorizo slices, jackfruit rendang, a canister of No-Egg Egg for £4.99. “That’s more than a carton of eggs,” says Buxton as she scans the ingredients. Gum cellulose dextrose, “That’s sugar. Do you want sugar with your eggs?”
You would expect the quality here to be better than anywhere else, but nutritionally, says Buxton, it’s a wasteland of chemicals and oils where nutritious protein should be.

“Someone’s going to arrest us in a minute,” she jokes. It does feel subversive. Like we’re poking around in veganism’s knicker drawer.

Isn't that more the 'con' of Marketing and Marketing food for the maximum profit?...

Meanwhile, there is no denying that going vegetarian or vegan avoids a huge and expensively wasteful cost of farming animals...

Depends where the animals are living.

If it's the UK, animal farming has a very low emissions problem. A quote from the article previously linked.
Lumping the UK in with global figures for countries with vastly different farming practices means that some of the good news gets lost. Beef cattle and sheep in the UK account for just 5.7 per cent of all UK emissions, but this is reduced to 3.7 per cent if carbon sequestration (storing of carbon in the soil) is taken into account. While she says it’s a cliché, “It really is the how, not the cow.”

An ordinary, average British 4oz steak, Buxton worked out from numbers in an FAO report, is about 1.9kg of CO2e.

But that Vegan takeaway you ordered from 5 miles away added 2.7kg of carbon emissions emitted by the vehicle delivering it.


And do you really want to be eating all those chemicals to replace the essential vitamins etc. that are not in vegetables but are in meats, fish and eggs.

Can we replicate what they do and take the worm out of the equation?

Styrofoam-munching superworms could hold key to plastic upcycling.

...Scientists at Australia's University of Queensland have now discovered that superworms -- the larvae of Zophobas morio darkling beetles -- are eager to dine on the substance, and their gut enzymes could hold the key to higher recycling rates.

Chris Rinke, who led a study that was published in the journal Microbial Genomics on Thursday, told AFP previous reports had shown that tiny waxworms and mealworms (which are also beetle larvae) had a good track record when it came to eating plastic, "so we hypothesized that the much larger superworms can eat even more."...
