New Solar Cell Harvests Hydrogen From Water

Engadgets is reporting that researchers at Penn State have built a new kind of solar cell that can harvest hydrogen directly from water. "The folks at Penn State have now developed a process that more closely mimics the photosynthesis process in plants, and while we won't pretend to understand all the nitty gritty of dye usage and other such nonsense, we do know that such a system could eventually attain 15% or so efficiency, providing a nice and clean way to gather power for that fuel cell car of the future."

Parent is first one to point out storage benefit... someone with points should mod up.

This is the biggest problem with solar/wind power, the power generated often needs to be supplemented with conventional generation technologies to ensure constant energy supply. Production of stored energy source like hydrogen solves this issue.
