Is it really cost effective to build a compact unit to extract hydrogen from H2O ?

Question by j l: Is it really cost effective to build a compact unit to extract hydrogen from H2O ?
Especially for transportation purposes…trains, cars, etc….I know on submarines , they extract the oxygen from H2O. Is there a car on the market where you can add water instead of gas/diesel ?

Answer by oiloiloilcoal
You have to inject more energy than you will extract. Submarines have a handy nuclear reactor as standard equipment to provide the energy for the extraction process.

What is the cost of one full battery charge for the Tesla Roadster?

Question by Tahini Classic: What is the cost of one full battery charge for the Tesla Roadster?
I like that electric sportscar. But is it really as efficient as they say? Wouldn’t your power bill end up looking a lot like your fuel bill used to with a regular car if you used it in the same manner?

Best answer:

Answer by John Sol
It does 2cents to the mile I heard, It must be efficient to get that sort of performance. It’s all on thier website.

Do a calculation for how much you would drive and figure out what sort of electric bill you would get, then compare that to a gas bill for the same mileage
