They are. Which is why you don't buy a new one, you swap it out for a
recharged one, or you plug in your car at home and at your destination.
There's a company setting up a network of charging stations across the
whole of BC:

And a Government programme to subsidise it. There's already a GP to
subsidise the production of the cars and this could be ramped up enormously.

Taxes yes, and why not? But fuel costs wouldn't be higher so long as
alternative means of making electricity already existing are developed
further, along with any new technology that might pop up.

So far. When more of them are being made the price will drop, which is
why subsidies are needed at this stage. And when gas has become so
expensive as it runs out that it's beyond most people's reach, then
we'll be glad that the technology for electric cars is already in place.

You could be right; I don't know much about the technology. But there is
a heat differential even at the depths coal mines reach, so I don't see
why that can't be used.

Well yes, there would be. If God had intended us to take energy out of
the ground, he would have provided us with tap roots.

Of course. But it would be even higher lunacy to keep calm and carry on
as if there were nothing wrong and the oil deposits were infinite, when
instead we can develop alternative energy sources and so escape the
crisis. Probably.
