Love That Dirty Water: ARPA-E Scientist Discovers Artificial Photosynthesis

MIT Chemist Dan Nocera can power your home with a glass of the Charles River

The idea is to use solar power for electrolysis - breaking water into hydrogen and oxygen - which then could be recombined when needed in a fuel cell, efficiently saving "almost all the solar energy," according to Nocera. "We emulated photosynthesis for large-scale storage of solar energy." [source] This means that with continued research and development, there could be wide spread access to solar cells that are both cheap and affordable.

This discovery and Nocera's prototypes are the product of 2009's US Department of Energy's Recovery Act, which provides funding for ARPA-E, the green, civilian version of its much scarier, bizarro-world counterpart, DARPA. Nocera presented his findings at ARPA-E's inaugural two day summit earlier this week.
