Using nature to grow batteriesin collaboration with
My dream: to be able to drive a virus-powered car.
Inspired by an abalone shell, Angela Belcher programmes viruses to make elegant nanoscale structures that humans can use. Selecting for high-performing genes through directed evolution, Belcher has produced viruses that can construct powerful new batteries, clean hydrogen fuels and record-breaking solar cells. Here, she shows us how it's done. Talk recorded 14 January 2011.
