Sun energy will be used without Sun



Donald Sadoway : MIT Professor of Materials Chemistry
Alternative energy like solar and wind will be used. 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."
