Bugs Make Juice To Run A Radio
Bugs make juice to run a radio. Now you can buy a battery that harnesses the energy of millions of harmless bacteria to produce enough electric current to run a small transistor radio.
The biological fuel cells are available as a kit that makes a battery of twelve cells, delivering about forty milliamps at six volts.
The experimental kit has twelve plastic containers filled with powdered brown rice husks. Bacteria, feeding on the husks create an electric potential between two electrodes in the mix. Occasionally adding water keeps the cell going.
