lauriebox rated 11 months ago- A Pollution free energy source is the topic of research .Scientist are working on this technology at Purdue.

- From the page: "Researchers at Purdue University have further developed a technology that could represent a pollution-free energy source for a range of potential applications, from golf carts to submarines and cars to emergency portable generators."

- This is very cool stuff. I love the fact that it's simple to convert ordinary internal combustion engines to run on hydrogen..which ultimately should help the environment and, hopefully, be a beginning to getting our cars to run on hydrogen.

- From the page: "Engineers perfecting hydrogen-generating technology" Silly Purdue students, nothing comes for free. You took the oxygen off the water, made hydrogen, but now you are stuck with the metal oxide. There is a reason Aluminum is so heavily recycled, it's expensive to make new Aluminum from the oxide. If they were REAL engineers they'd understand this... Basically you are using Aluminum as an energy storage device. You use energy to make the Alumina into Aluminum, then use the Aluminum to make hydrogen, and more Alumina, and then convert the Alumina back into Aluminum. If the cycle were perfectly efficient, you'd have gained no energy (obviously) and you still need to use the hydrogen perfectly efficiently to come out even. Since no cycle is perfectly efficient, you come out behind. The more complex the cycle, the more likely you are behind. As was pointed out earlier, electrolysis is simpler, and probably more efficient. This is what happens when you sleep through thermodynamics class kiddies...

- "Purdue researchers demonstrate their method for producing hydrogen by adding water to an alloy of aluminum and gallium. The hydrogen could then be used to run an internal combustion engine or a fuel cell. The reaction was discovered by Jerry Woodall, center, a distinguished professor of electrical and computer engineering. Charles Allen, holding test tube, and Jeffrey Ziebarth, both doctoral students in the School of Electrical and Computer Engineering, are working with Woodall to perfect the process.
