The Liquid Metal Battery

From Ted Talks:

"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."

Today there is no battery technology capable of meeting the demanding performance requirements of the grid: uncommonly high power, long service lifetime, and super low cost.

Don Sadoway and his team sought to make a battery out of earth elements. Preferably locally sourced dirt! Here is the inside story of the liquid metal battery.
