Scientists at Stanford University have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas. Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive and abundant nickel and iron.

HHO people have been using stainless steel electrodes for decades now in their cells. 1.5V is right in the middle of the voltage range per electrode pair, and not even the peak gas/waste heat voltage. What’s special about this?
I’d say that in 20 years or so, we’ll start to see energy beocme cheap and plentiful, to the point where most people consider it virtually free. (Of course I’m also hopeful we’ll eventually see wireless internet virtually free too.)I think there are plenty of promising factors for Solar and Wind and the like, as those get better. And even Nuclear has it’s place, alternative reactors like those for Thorium might be a big advance. Oh, and what about that Fusion reactor, eventually those might work.Also, maybe by that time oil will start running out.. I think we’ll need a push like that, to move to alternative power sources. =/
