Electricity From Viruses

Posted on: May 20th, 2012 by partapsingh No Comments

Here comes the grey goo! Scientists at U.C. Berkeley have created a tiny generator using a combination of pressure and a film of specially engineered viruses that covert mechanical energy into electricity. You can read the BBC story here.

The viruses – which apparently only attack bacteria and are harmless to humans (for now) – can only produce enough energy to make the number “1” light up on an LCD. But think about what we’ve got here: potentially self-replicating, self-assembling viruses that get more energetic under pressure. This is going to be grey goo, right? This is what could power nanotechnology gone wild – tiny little virus-powered robots proliferating all over the place, pushing life as we know it out of the way.

Okay, okay, so I’m going a bit overboard on the scifi side, but remember that the grey goo scenario wasn’t thought up by science fiction writers, but by mathematical genius John von Neumann and nanotech researcher Eric Drexler. As long as we’re just talking about robotics and electronics, we really don’t have much to worry about, but once you start throwing biological material in – material that is designed to evolve and adapt on its own – then things get much more interesting.
