A professor at MIT claims to have Mother Nature beat at her own game. Dr. Daniel Nocera says his invention is ten times more efficient at photosynthesis than a real-life leaf, and could help to bring affordable alternative energy to developing countries. Described as an "advanced solar cell the size of a poker card," the device is made of silicon, electronics, and inexpensive catalysts made of nickel and cobalt. When placed in a gallon of water under direct sunlight, the catalysts break the H2O down into hydrogen and oxygen gases, which are then stored in a fuel cell -- the energy produced is apparently enough to power a single house for a day. Of course, this isn't the first time we've seen scientists try to one-up nature, in fact, we've seen solar-powered leaves before, but this thing actually looks poised for the mass market -- Nocera signed a deal with Tata in October. Full PR after the break.MIT professor touts first 'practical' artificial leaf, signs deal with Tata to show up real plants originally appeared on Engadget on Mon, 28 Mar 2011 15:54:00 EDT.
