Scientists Made a Virus That Can Charge Your Batteries

[JMH]

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have found a way to exploit the harmless kind of organisms that usually make you sick to charge your gadgets.

The researchers said they have successfully engineered viruses that create electricity in response to mechanical stress. In an experiment, they coated a stamp-sized electrode with the virus, which then generated electricity as soon as the scientists tapped the surface of the stamp. This current design, the first product that uses the piezoelectric properties of a biological material, produces enough energy to power a small LCD. Future designs could be integrated, for example, in shoes or clothing - or common movable objects such as doors or wheels - to create much more energy, power gadgets or charge their batteries.
