Yes Zuts, its all bull. There were a few test electric cars around a few years ago that were only for lease, you couldnt buy them, and then a huge conspiracy theory why they were all suddenly withdrawn and stopped production. It was explained in detail, that to have a few weird cars around that needed a huge infrastructure in spares and support within a reasonable reach of users, was just financially impossible, with the almost zero interest in meaningful volume sales in the near future. The media skimmed over that little detail.
Bones, its not the car, its not the car, its the inefficient, green house gas producing power to charge the batteries in the 1st place. And yes, when alternative power generation hits the straps, then its all good. They need to just forget alternative cars for a while and concentrate just on producing the juice in the 1st place, thats where the action is.

I agree with you there, if you use electrolysis to produce the hydrogen for the cars. Uses up far too much energy for little return. However, there has been a few ideas about burning water (with a catalyst or without) as a fuel. Might come as a surprise but water will burn, at a high enough temperature. That's also a problem....the engineering of a suitable engine. Especially in so far as materials engineering....making manifolds and such that can take the temperature.
All cars cost a lot of money to design and initially get out into full scale production and use. Costs in order of a billion dollars to do so. That's why cars are as dear as they are, and why they tool up to produce so many. To recoup costs. Electric cars would be much the same, in some cases even dearer, given present technologies.
And so, you swap one greenhouse producing enterprise for another. Forget the batteries and alternative cars, let's just stick to producing petrol powered vehicles and make things even worse than they've already become. However, I agree that they'll have to find a better way of recharging them than using coal fired power stations to produce electricity.
