Israeli Scientists Make a Major Hydrogen Fuel Breakthrough

Developing a way to create hydrogen fuel from water is a "Holy Grail" of alternate fuel development. Many consider Hydrogen fuel sells the perfect pollution-free alternative to fuel automobiles. In these cells Hydrogen is consumed by a pollution-free chemical reaction, not combustion. So the fuel cell simply combines hydrogen and oxygen chemically to produce electricity, water, and waste heat. Nothing else. hydrogen is the most abundant element in the universe, it would take millenniums to run out. Up until now the major problem with creating hydrogen fuel cells is the chemical process needed to seperate the hydrogen and the oxygen used as much energy as it produced. The Weizmann Institute in Israel may have found a way to solve that problem:

...except stupidity.

Thanks gw. That excerpt was pretty bad though, had to go to the originating page. VERY interesting:

It is relatively easy to turn hydrogen into clean energy. The problem is getting clean energy in order to to make hydrogen.

[grey_whiskers]

It potentially minimizes the need for oil, and it's from Israel?

Now the Arabs will *REALLY* hate the JOOOOOOOOOOOOS. /sarc>

Cheers!

That would be epic sweetness!

“.... it would take millenniums to run out.”

I’d hate to be around when that happens....

Yarmulke good point there.

"Closest naturally occuring source: The Sun.Have fun retreiveing it, don't forget the coppertone."

"Good heavens! They've come up wth the perpetual motion machine."

Why is it, that on every thread that involves potential alternate energy technology, numbskull nutcases like you two pop up with know-nothing comments like the above????

[Wonder Warthog]

"Normally I would dismiss the idea that someone could produce hydrogen from water using less energy than one gets by oxidizing the hydrogen produced."

Where do you dredge THIS idea up?? There are two energy inputs into the process, one photochemical and one thermal. I see nothing in the article that implies that there is less energy used to produce the H2 than is obtained by oxidizing it.

[Wonder Warthog]

"Properly used, fine, but lots of engineering needed."

Once upon a time, the same was true for gasoline. Hydrogen is used on a daily basis at tens of thousands of locations in the US. Very few problems. The "lots of engineering" has already been done.

Sorry genius. I guess I didn't choose my words carefully enough for you. I was thinking of the energy from other stored energy sources normally needed to separate hydrogen and oxygen such as electrical energy used in electrolysis. The light from the sun utilized in this process is effectively infinite and so it doesn't really count.

We could always get it at night. ;-)

Just the basic Laws of Physics my FRiend, there are only three of them and they are not that difficult to understand.

They have not been violated yet, except by the Almighty.

"“When we exposed this third complex to light at room temperature"...

OK. If I understand this correctly, my vehicle's fuel will have to be generated in a "closed" system to contain the fuel, but will have to be generated in an "open" system so that the 3rd stage can be completed. That is, unless a flashlight will suffice. Then my key-ring flashlight can be connected through an O-ring into the "closed" fuel generator.

Now I have to figure out how many batteries I have to keep on hand.

IAC, I'm trying to avoid even thinking about the net efficiency of the reversion of the 500 lbs (?) of the metal complex to it's original state so that I won't have to haul a trailer full of the stuff for replacement.

I'm really encouraged. Got to try to figure how much H2 will be needed to run a Ford 350 hauling whatever.

Because I've studied physics and chemistry. The laws of thermodynamics (which have never been broken) tell us you can't break the chemical bonds that hold hydrogen atoms to oxygen, then combine them back together and gain energy. You can't wind up a spring and get more energy out of it by letting it unwind then it took to wind it. You can't un-burn wood ashes and then burn them again.

Maybe you should spend a little more time reading the article, which says nothing like the above. The chemical process involved contains not one, but two energy inputs---on photochemical and one thermal. So your comment stands as idiotic. As to "studying chemisty and physics", I have PhD in the former--so go back to school.

See 39. It applies to you, too.
