I can't believe that only a few years ago, water powered cars were super futuristic. I actually remember a book where the cars ran on water and water prices were really high.
Hydrogen is held in 4.1 kg @ 5000psi (Hydrogen is sold in Kilograms). Runs with an EPA 61 MPGe (Miles Per Gallon equivalent) achieving a max rang of 240 miles per fill up. The tank although only holds a little fuel is massive with heavy side walls.

It uses Oxygen from the air.

James may drives the FCX Clarity:

Now only if it could collect some of that water and fed it to a water and or ice dispenser, that just be the beans to it's bacon. Or even a keurig... but that'd probably just be in the Rolls Royce version.

sailor Check the real current sources for Hydrogen: http://www.google.com/url?sa=t&rct=j...,d.eXY&cad=rja

95% from hydrocarbons, with most of that from natural gas.

Straight electrolysis is WAY too expensive, and adding distilling from ocean water would be crazy expensive. It's not even the latest method for getting drinking water from the ocean (diffusion membrane plants are catching on).

Another case where the "green" propaganda doesn't match reality.

BTW - I'm an outdoors person and hate messing the environment in stupid ways, environmental activists at the extreme are just off the wall. Getting rid of people because people mess up the Earth is a key point (hidden agenda) if you look close at them. Of course they all think they're part of the elite few who will still populate the Earth. (rant)

A1_Fares In a way they run on water! Since you need to make water to create the electricity. Lol

However much they use, its easy to make. Just take ocean water, boil it to get rid of the unnecessary minerals, then diffuse it. Unless there's other ways to find hydrogen in nature which I doubt since it's a freaking micro bomb.

sailor Remember, they don't RUN on water, they produce it.

I don't have output/storage specs on hand for hydrogen, there are some wild storage systems like absorption into a metal lattice to store more at lower pressures.

Your car produces a LOT of water right now, not as different as you might think.

sailor CotyM got it right, for now the "hydrogen economy" is just a way to store & transport power made from other sources.

There's the Hindenburg factor to slow things down as far as adoption, that problem has been solved before. Adding an odorant to natural gas made it safer than the almost odorless gas it can be. (always done after disaster, Texas? school blew up)

EVERY power storage system bottles up enough juice to do major damage in the wrong circumstances...

sailor "Fuel Cell" can take Hydrogen & Oxygen to make water & produce mostly electricity directly instead of heat. Not like burning to power a generator to make electricity.

Skips steps & is much more efficient/clean.

A1_Fares In that situation, you'd be filling the car with hydrogen and the oxygen you'd get from, well, the air which can be mixed into the 02. None of that in home diffusion bs. You'd still need heat to combine the two. Unless they stick together in mid air.. Haha. I'm even more interested to really study these new engines now.

CotyM ^Yep that's why hydrogen powered cars like the Honda FCX Clarity use an electric drive train, the power is generated by mixing hydrogen and Oxygen, the result is that when these two elements merge into water they produce a high voltage discharge. The fuel cell is designed to collect this energy and use it to power the car and recharge the battery...

In the end all it is is an electric car than you can fill up in about 2 minuets, because it still essentially uses electric from power plants to make your fuel.
