Lake Powell is artificial, and most of its water is exported to Arizona, Nevada, and California. There's nothing natural going on there.

Parking meters may be ugly, but there are a lot of them around, and throwing in a charging socket would trivial - Canadian parking meters already power your stop-the-radiator freezing heater ...

The paying-for-charging negotiation would be electronic, between the car and the charger. Next guy might unplug you and connect himself, but he'd pay for the current.

An electronically controlled mechanical lock on the charging plug/socket wouldn't be impractical.

In the old garden of Eden, there was no economy; all needs were satisfied. For breathing air, that's still the economic model, but it's an illusion: the (1952?) black fog in London killed thousands, and air-quality regulation, with its associated costs, has been with us ever since.

We don't just WANT air, we need it. Oil and gas, we just want. People can live without consuming petrochemicals.

Corporate sales of air are not distorting your perceptions, but those of gas and oil and coal put a LOT of PR money between your eyes and the reality.

Before modern technology, the average life spen was about half what it is now. Most kids died.

For breathing air, that's still the economic model,

Unfiltered coal burning is nasty. Natural gas is great stuff: cheap, reliable, safe, and clean. People keep finding more. Coal-fired power generation is declining in the USA because gas is so cheap.

A fraction of the planet's current human population would survive without the energy, materials, and fertilizers that we get from oil and gas.

The reality is that it's warm and dry in my house, we have electricity and hot+cold clean water, my gas-fueled car is outside if I want to run to Safeway and restock my electric-powered refrigerator with stuff shipped (with oil powered ships, trucks, trains, planes) from all over the world.

How would you do if all that oil and gas powered stuff just stopped? Happy without electricity, heat, food, transportation?

The metal resource needed to make all cars and vans electric by 2050 and all sales to be purely battery electric by 2035. To replace all UK-based vehicles today with electric vehicles (not including the LGV and HGV fleets), assuming they use the most resource-frugal next-generation NMC 811 batteries, would take 207,900 tonnes cobalt,

264,600 tonnes of lithium carbonate (LCE), at least 7,200 tonnes of neodymium and dysprosium, in addition to 2,362,500 tonnes copper. This represents, just under two times the total annual world cobalt production, nearly the entire world production of neodymium, three

of electric vehicles only, from 2035 as pledged, will require the UK to annually import the equivalent of the entire annual cobalt needs of European industry.

The European/UK public chargers don't have the cable - you always use an extension cable that is the property of the car owner.

The cable is locked in place on the car and the charging station while charging is in progress.

Currently only Tesla uses authentication between the car and charging station for billing purposes.

The high-speed DC charging standard implemented on all EVs that support it has a communication channel provided for car to charger negotiation for such purposes - only needs appropriate software, no physical changes required to existing designs.

Most EVs already do that and lock the charging plug in place when the car doors are locked..

They got malnourished every winter - everybody except the rich had annual s tarvation rings on their teeth. The agricultural revolution fixed that, but infectious diseases still killed a lot of kids.

Sewage, hygiene and clean water aren't exactly modern technology.

Sadly, even burning natural gas injects enough CO2 into the atmosphere that we can't afford to get much of our energy that way.

But we don't have to get them by burning oil and gas, and we really shouldn 't be using them up a lot faster than they are being laid down, quite apart from the nasty effect on atmospheric CO2 levels.

All of which you could have if the power you used was being generated by Wi ndmills and solar farms. A battery powered car would work just as well as y our Audi, though you'd need it have the moving parts enclosed in some kind of pretentious body work before it would satisfy your vanity.

You don't need to burn fossil carbon to generate electricity. We've being g enerating it that way for about a century now, but wind an solar generation is now cheaper, even after you've thrown in the batteries and the pumped s torage you need to carry you over the gaps when wind and solar aren't deliv ering.

So manufacturers and their buyers of electric vehicles will be precipitating a global environmental disaster and the rape of all the world's rare earth metals, eh? We need to reverse this environmentalist madness before it destroys the planet. We need to: Forget all about "renewable energy sources" and embark on an ambitious program of nuclear power station building, Ban the development of electric vehicles and start subsidising research into clean diesel engines (which was doing very well by itself before governments interfered with the program), Forget all about switching from plastic packaging to paper and foster development of bio-degradable plastics. It's all so simple and obvious really. I could do a better job than the politicians have in my sleep. Only politicians could f*ck things up they way they have. Parasites.

So what? Increase the demand, and the price goes up. Raise the price and a whole lot of mines will open up again that got closed down because their de posits weren't as easy to extract as those at the happy few who were able t o satisfy world demand when it was lower.

When I was growing up in Tasmania, Tasmania's tin mines were forever being opened up again when the tin price was high, and closed down again as soon as there was enough supply to push the tin price back down again.

Some people don't seem to understand how free markets work.

Then one morning you get up a bit earlier than usual and find some clown's taken a tap off your extension lead to run the fans and lights for their guerrilla cannabis grow. :-D

Traditionally they used an insulated hack saw to cut the cable off the plug and the socket, and sold the rest of the cable to a scrap metal dealer for the price of the copper content.

Taking a tap off without electrocuting yourself is trickier, and getting the power in a form which will run your fans and lights is trickier still. But you need to know stuff about electricity be aware of this, and Cursitor Doom clearly doesn't.

The next guy would be out of luck, I'm sure it can be arranged that either the cable would refuse to disconnect or that the charger would refuse to charge his car.

  When I tried casting out nines I made a hash of it.

The problem with you lefties is that you _really_ believe that government can deliver you to the Garden of Eden, when in reality, your socialist ideas bring hell on Earth. The last hundred years should be plenty of evidence but your eyes will never see.

Petrochemicals like CO2?

They make my life *immensely* better. They _allow_ all good things from clean water to clean air for a few billion people. But your eyes will never see.

Script kiddie, at best.

Billing? I thought they were free!

No, never. It's always 75F and sunny in Vermont, except on the ski slopes. All lefties should move there now! It's one place their politics can't destroy.
