Using nature to grow batteries: Angela Belcher on TED.com

Posted by: Jenny Zurawell

Inspired by an abalone shell, Angela Belcher programs viruses to make elegant nanoscale structures that humans can use. Selecting for high-performing genes through directed evolution, she’s produced viruses that can construct powerful new batteries, clean hydrogen fuels and record-breaking solar cells. At TEDxCaltech, she shows us how it’s done. (Recorded at TEDxCaltech, January 2011 at Pasadena, CA. Duration: 10:26)
