Virus based batteries?

A breakthrough at MIT allowed a team of researchers to create virus based batteries, the main idea behind this is having tiny cells, which in turn would allow to have very small sized batteries that could be use to power really small electronic gadgets and maybe after a more study even electric cars. Even though there is not a finished prototype yet, things seem to be going just fine and two of the three most important components have been successfully put together, the full announcement is here.
