Aluminum alloy extracts hydrogen from water

Posted on Thursday, May 24 2007 @ 05:53:14 CEST by

Professor Jerry Woodall and students from Purdue University claim they've found a way to extract hydrogen from water by using an aluminum alloy.
Woodall says the method makes it unnecessary to store or transport hydrogen — two major challenges in creating a hydrogen economy.

"The hydrogen is generated on demand, so you only produce as much as you need when you need it," he said in a statement released by Purdue this week.

So instead of having to fill up at a station, hydrogen would be made inside vehicles in tanks about the same size as today's gasoline tanks. An internal reaction in those tanks would create hydrogen from water and 350 pounds worth of special pellets.

"No extra room would be needed," Woodall said, "and the added weight would be the equivalent of an extra passenger, albeit a pretty large extra passenger."

The hydrogen would then power an internal combustion engine or a fuel cell stack.

"It's a simple matter to convert ordinary internal combustion engines to run on hydrogen," Woodall said. "All you have to do is replace the gasoline fuel injector with a hydrogen injector."

Did anyone actually bother to read the whole article? And realize; it takes energy to turn Aluminum Oxide back into Aluminum and Oxygen? Ohh yea, other than the energy it takes to dig out and refine aluminum in the 1st place.
It's just a chemical reaction. Net Energy LOSS when you factor in total costs.
Hydrogen Economy is stupid.
I'm all pro-Eco and pro-Tech. But please, don't take your science from any MSM news.
