Donald Sadoway is working on a battery miracle -- an inexpensive, incredibly efficient, three-layered battery using “liquid metal."
Why you should listen
The problem at the heart of many sustainable-energy systems: How to store power so it can be delivered to the grid all the time, day and night, even when the wind's not blowing and the sun's not shining? At MIT, Donald Sadoway has been working on a grid-size battery system that stores energy using a three-layer liquid-metal core. With help from fans like Bill Gates, Sadoway and two of his students have spun off the Liquid Metals Battery Corporation (LMBC) to bring the battery to market.

Reinventing the battery: Donald Sadoway at TED2012
February 29, 2012
Photo: James Duncan Davidson “The electricity powering the lights in this theater was generated just moments ago,” says MIT professor, Donald Sadoway, now on stage at TED2012 to talk power. “The way things stand, electricity demand must be in balance with electricity supply.” The problem is: coal and nuclear plants can’t address demand fast enough. How […]
