Stanford researchers find electrical current stemming from plants

In an electrifying first, Stanford scientists have plugged in to algae cells and harnessed a tiny electric current. They found it at the very source of energy production - photosynthesis, a plant's method of converting sunlight to chemical energy. It may be a first step toward generating 'high efficiency' bioelectricity that doesn't give off carbon dioxide as a byproduct, the researchers say...
