Another potentially planet changing breakthrough from MIT scientist Daniel Nocera and the Tata Group. From Fast Company:
Just 45 days ago, Nocera and his team stuck an artificial cobalt- and phosphate-coated silicon leaf into a jar of water and managed to create power--at an efficiency that surpasses today's solar panels, no less. The technique mimics photosynthesis by splitting hydrogen from water to generate power from the sun.
Tata and Nocera imagine that the research could lead to a refrigerator-sized "mini power plant" in a development that could, according to Live Mint, bring power to the three billion people currently living without.
Check out an interview with Nocera explaining the technology he has been working on for the past 25 years:
