Angela Belcher: Using nature to grow batteries

The video explores the potential of using biological processes to create advanced materials. It begins with the abalone shell, a natural biocomposite, and discusses how its structure can inspire new technologies. The speaker envisions bio-inspired batteries and solar cells that mimic natural processes, using genetic information to improve over time. The talk highlights the role of simple organisms in material formation and the potential of using the periodic table to innovate new materials. The speaker also describes engineering viruses to create high-powered batteries and efficient solar cells, showcasing the potential of biotechnology in material science.
