M13 is a natural power source, but researchers enhanced its output by genetically engineering the virus, adding some negatively-charged amino acids to one end of its tough outer shell. Basically, the GMO version of M13 became a better voltage generator, because it had a negatively charged end and a positively charged end, thus aiding the flow of electricity. Then, they tested it.


According to a release from Berkeley Lab:

They created the conditions for genetically engineered viruses to spontaneously organize into a multilayered film that measures about one square centimeter. This film was then sandwiched between two gold-plated electrodes, which were connected by wires to a liquid-crystal display.

When pressure is applied to the generator, it produces up to six nanoamperes of current and 400 millivolts of potential. That's enough current to flash the number "1" on the display, and about a quarter the voltage of a triple A battery.


Obviously this is a beta version of what's to come. Berkeley bioscientist Seung-Wuk Lee, who worked on the project, is hopeful that it can pave the way for more research into virus-powered electronics. I think we're all looking forward the day when we can power our monitors just from slamming our heads onto (M13-covered) desks while streaming Transformers 2.
