MIT has pioneered a Virus battery.

Researchers constructed a lithium-ion battery, similar to those used in millions of devices, but one which uses genetically engineered viruses to create the negatively charged anode and positively charged cathode.

The virus is a so-called common bacteriophage which infects bacteria and is harmless to humans.

Amazingly it is already marketed as something that can power cars, which says a lot about demand versus the auto industry. Who killed the electric car, indeed!

It also is nice to see viruses get a good name, given all the negative press that we usually see in technology. Go battery virus go.
