Donald Sadoway: The missing link to renewable energy

The video discusses the need for balancing electricity demand and supply, highlighting the limitations of current energy sources. It introduces the liquid metal battery, a new energy storage solution developed at MIT, which addresses these challenges. The video covers the history of battery invention, the inspiration from aluminum production, and the design of the liquid metal battery using earth-abundant materials. It also details the development process, scaling efforts, and the innovative approaches taken, such as mentoring students and focusing on cost-effective production.
