We all know that. But do you want to use the Polar Ice to make it? Than every boday in low line area will be swimming other than driving.

Let's see even a small prototype. Well we have to purify the catalyst, purify the water and do all the solar structure. Many questions such as cat life, etc. Also compress all this stuff for use. It will happen but later.

Alright, so we've tried food as fuel via ethanol and that has produced increased food prices with no real benefit. So now we're going to try water as a fuel? WTF??? Really folks, we done have a bunch of excess clean water flowing around.

Boy i can't wait to pay $4/gallon for water

What if they use the alternator to generate the energy? Endless-running car! Yay!

Fresh water is too valuable a resource to be using it for fuel. Just ask the people in Southwest US who are fighting over States water rights.

Sea Water is a great resource. If they can do it with that, you have a nearly inexhaustable source.

I wish these kinds of articles would have journal references.

[quote]the research group claims that has developed a catalyst that “effectively catalyzes” one of the necessary half reactions[end quote]

May I point out thesaurus.com?

I'd replace "catalyst" from above quote with "system" or "stimulus".

And with a second looks like an "it" is missing between "that" and "has".

Sorry. I'm a QA Engineer, not a journalist. My job is to find problems. And this is serving as my defect submission form. =0

You use sunlight as the energy source, to turn water in fuel (hydrogen) plus oxygen. The oxygen you release into the atmosphere (just as trees do in photosynthesis). The hydrogen you store as fuel.

When you eventually take the hydrogen fuel out of storage and use it ... you burn it. That means combining it back again with oxygen (the exact same amount as you released before, BTW). You get energy from that burning, and the waste is ... water vapour!

A completely closed cycle. No carbon involved at all. Sustainable (as long as the sun shines). Total water used by the whole process = ZERO! Not one molecule of water used. Every single molecule of water originally split into hydrogen and oxygen is recombined back to a water molecule at the end of the process.

If this works, it would be a great step toward the economical and environmentally friendly production of hydrogen. Although cars can be made to run on hydrogen using internal combustion, this is inevitably a very inefficient conversion of energy. If the challenges of using fuel cells, instead, can be overcome, then I think we'll have a complete, efficient, and nearly inexhaustible system of powering our future cars.

As an aside, the statement "We increasingly hear about ideas that suggest that future engines in fact may be able to run on water..." is misleading. The engines would not be "running on water" any more than your air conditioning "runs on freon"; water would simply be the "working fluid", transporting energy from one place (or form) to another. The engine would actually be running on sunlight.

My 2 cents,
Richard

This kind of research became very popular, because scientists like the idea of having a portable fuel cell that can be charged up very quickly.
