hydro power??

Gas. I just got that out of a Motor Trend, so the source is probably reliable.

[ivymike1031]

if he simply said that a hydrogen powered vehicle gets 50% better efficiency than a gas-powered vehicle, then the author hadn't a clue what he was talking about. Was the article about fuel cells, about Hydrogen-fueled IC engines, or what? Was he talking about the efficiency of a fuel cell by itself, or the overall efficiency of the propulsion method? I wouldn't count on a Motor Trend magazine (or any consumer magazine for that matter) being an accurate source of info. A general rule of thumb about the editors/authors of automotive-related magazines: they're english majors with an interest in cars.

So true.

I think it was on fuel cells.

Size and safety problems aside they actualy have to create a long lasting and stable fusion reaction before you can even consider useing it as a power source.

The Doc did it in BTTF.

There's one thing alot of people don't realize about hydrogen fueled cars. They can't just drill for the stuff and it's not cheap to make.

Hydrogen is the most abundant element in the universe. Where's the shortage?

Its not that there is a shortage (Read more carefully), Its just that it so expensive to produce large quantities of hydrogen and store it. The three main ways of acquiring H2 (natural gas steam reforming, water electrolysis, and through biological processes) are not at stage right now were they could be considered anywhere near cost efficient. So yeah, we got a ton a hydrogen but there's not an efficient way to get to it yet.

The shortage is on earth... unless you know of a good way to capture hydrogen from distant stars!

Hydrogen makes up about 0.14% of the earth's crust, largely bound up in hydrocarbons, and it's even less abundant as H2.

what about water (H20)? Not too much of a shortage if you consider electrolysis as a method for producing hydrogen. Then again, as of now its hard to produce it in large quantities with this method.

well riddle me this, riddler - how do you propose to power your electrolysis machine?

Why a nuclear fusion reactor of course

bah, tokomak's and hydrogen bah!!

I think we should all just convert to burning alcohol. Of any kind, really. So i'f im low on gas at home, and i have a bottle of 151, i could just our that into the tank.

In all seriousness, i'd rather see us go to alcohol. Replenishible, cheap to convert cars, cleaner...

That's really only true if you assume that an "environmentally friendly" source of H2 is found. Currently the best place to get the H2 is by hacking it off of hydrocarbons (ie methane), and by the time you're done with it, you've used considerably more methane than you would have used if you'd just burned it in the engine. Since cleaner sources of hydrogen are currently either sci-fi (fusion reactors that produce energy instead of consuming it), just too expensive (solar), or not widely available (ocean turbines, etc), I don't see any benefit of using H2 in vehicles for quite some time. Current "expert estimates" of when H2-powered vehicles will be more environmentally friendly than diesels, diesel-electric, or gasoline-electric hybrids, put the date somewhere beyond 2020.
