Coming on the heels of the Oregon PUC’s decision in the Honeywell case (see Steve Hall’s blog below), scientists at MIT announced today that  they had discovered a cheap way to separate oxygen from hydrogen using techniques learned from studying plant photosynthesis.  Once separated, the hydrogen and oxygen can be used to power a fuel cell.  During the daytime, a home would run on solar power–at night, it would draw energy stored in the fuel cell.

Could this development be a game changer?  The full story is to be published in Science today–in the meantime, check out ScienceDaily.
