Using nature to grow batteries Angela Belcher

Inspired by an abalone shell, Angela Belcher programs viruses to make elegant nanoscale structures that humans can use. Selecting for highperforming genes through directed evolution, she s produced viruses that can construct powerful new batteries, clean hydrogen fuels and recordbreaking solar cells. In her talk, she shows us how it s done. (Filmed at TEDxCaltech. ) Talk by Angela Belcher.
