Generate electricity from grapes

Scientists from the University of Texas at Austin (University of Texas at Austin - UT ) made grapes to produce electricity due to the so-called biofuel cell (biofuel cell). The cell consists of two carbon electrodes (cathode and anode), each of which is thinner than a human hair, and collects the energy produced by plants as a result of glucose and oxygen metabolism. This cell is producing only 2.4 microwatt, that is, for ordinary light bulbs they will need a few million. Device works best where much glucose - in grapes.

Now scientists are trying to make the cell work in insects or small animals, however, test grasshoppers yielded nothing. In the future, improved cell can produce power tiny autonomous sensors and chips, but talking about it is too early.
