I saw that, I actually saw these on the Science Channel a few months back. They are good. Anything that a large Corp. like Panasonic would put their name on is going to work. But from what I remember its just not that cost effective or efficient for the average person. Keep in mind a Large Corp is trying to make Max. Profit$ also so just to purchase it would probably be Crazy Expensive.

One Model they showed that I think Phillips developed was a Solar Powered Model Like this, that was just a Giant Electrolyzer that also separated the H and O for running a pure Hydrogen Vehicle Cell. They don't show allot about those devices, I guess so no one steals their idea or whatnot.

You could very easily design and build one of these yourself. I have thought about using my spare windmill set-up just to see how it would work, but as of now I have no use for stored H at my house.
