this could get interesting

"Hydrogen production now involves a large amount of CO2 emissions," Sunkara said. "Once this alloy material is widely available, it could conceivably be used to make zero-emissions fuel for powering homes and cars and to heat homes." [tgdaily.com...]

I hope this isn't another cold fusion [en.wikipedia.org] story.

Through theoretical computations, they've demonstrated that an alloy formed by a two percent substitution of antimony in gallium nitride has the right electrical properties to enable solar light energy to split water molecules into hydrogen and oxygen, a process known as photoelectrochemical (PEC) water splitting.


If the fuel is taken from tap water then this will be a cheap fuel. But if the costs of the alloy is the issue then it will be a big problem. Looking forward to see this great discovery in action.

I don't want cars drinking my local ground water, we've got enough problems with people and lawn watering to have to deal with cars sucking up supply.

1. The oceans are full of water.

2. The byproduct of using hydrogen in an internal combustion engine is H2O.

No problem. We Canadians will sell you all the fresh water you want ... at $90 per barrel!

1. The oceans are full of water.


yea salt water that would corrode the hell out of an engine and all parts in between. desalinization isn't cheap enough yet, at least not for fresh human drinking water, but if they'd truck in desalinized ocean water for cars im all for that. Just stay out of my drinking supply


2. The byproduct of using hydrogen in an internal combustion engine is H2O.


which doesn't directly fall back to the ground and soak back into the aquifer, even if such a miracle did happen it would take a lonnnnng time to make its way back, it would also have to rain directly on a recharge zone.

im in FL... people keep moving in, people keep building houses, and they keep sucking the ground dry. Sink holes don't happen for no reason, and this is in a state the gets more then its fair share of rainfall.

Holy cow J-RaD, there's no sodium chloride in hydrogen.

Maybe you have a valid point in there somewhere, I just can't see what it is.
