No more alkaline batteries. No more NiCad's. No NiMH's. No Lithium. Forget all of those hazardous chemical reactions in the batteries and think eco-friendly. Professor David Edwards did.
Edward's group Lebônê, incubated at Harvard, has developed a way to make batteries from nature. Microbial fuel cell (MFC) batteries generate energy from bacteria in the soil and consist of a graphite-cloth anode, a chicken-wire cathode, manure and mud, a sand ion barrier, and salt water as electrolytes.
Save developing nations, save the planet, in one word: revolutionary.
Popular Mechanics named the Harvard team one of the 10 Most Brilliant Innovators of 2009.
