Virus battery could 'power cars'

Viruses have been used to help build batteries that may one day power cars and all types of electronic devices.

The speed and relatively cheap cost of manufacturing virus batteries could prove attractive to industry.

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

Three years ago the MIT scientists manipulated genes inside a virus that coaxed the particles to grow and self-assemble to form a nanowire anode one-tenth the width of a human hair.
