What's the key to using alternative energy, like solar and wind? Storage -- so we can have power on tap even when the sun's not out and the wind's not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: "We need to think about the problem differently. We need to think big. We need to think cheap."

Donald Sadoway: The missing link to renewable energy

The missing link to renewable energy

Inventing the liquid metal battery, a game-changer for storing renewable energy, ensuring sun or wind power is always available.

Scaling up from a 'shotglass' to a 'pizza', this innovative battery aims to meet the daily electrical needs of 200 households.

A blend of creativity and science, the liquid metal battery project reshapes our approach to renewable energy storage solutions.
