I can't believe this one. It is a container with a output. You put in aluminum and koh with water and you get out Hydrogen. NO electricity needed. LOL how do you turn it off? I was under the impression that aluminum hho is poisonous.

not at all.. aluminum has a stronger bond with oxygen than hydrogen and oxygen. Natively the problem with this is that the aluminum forms a skin of aluminum oxide and stops the process. But a EE from Perdue figured out a way to prevent this. I assume by accident he dropped a piece Aluminum Gallium Arsenic (the stuff they make LEDs out of) into water and it created hydrogen. Turns out the Gallium prevents the skinning to form. http://www.physorg.com/news98556080.html (http://www.physorg.com/news98556080.html)
nice!
So how do you turn it off. Do you have a manual screen you lift the metal out?
stop the flow of alluminum gallium into the water.. gallium disolves the aluminum.. it's a liquid from what it says
