tw, you've picked the bits out that you wanted to argue and that's fine. Nowhere did I stipulate that mass production was the only way to reduce costs. Generally, in order to 'mass produce' something from a prototype it is necessary to innovate, so I would have thought that someone with your superior intelligence would have taken that as a foregone conclusion.

As to hydrogen fuel cells.

I'm not a scientist so I'm not able to argue the figures with you. All I'm trying to suggest and demonstrate is that real life trials are being run and they're working. Of course they're expensive. All trials are.

Are you suggesting that scientists should stop trying to provide new forms of energy? What alternatives would you like to discuss, as opposed to simply denegrating suggestions made by others.
