Donald Sadoway is working on a battery miracle -- an inexpensive, incredibly efficient, three-layered battery using “liquid metal."
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.
“With a giant battery, we'd be able to address the problem of intermittency that prevents wind and solar from contributing to the grid in the same way that coal and gas and nuclear do today.”
“If we're going to get this country out of its current energy situation, we can't just conserve our way out. We can't just drill our way out. We can't bomb our way out. We're going to do it the old-fashioned, American way. We're going to invent our way out, working together.”
“In a battery, I strive to maximize electrical potential. When mentoring, I strive to maximize human potential.”
“The liquid metal battery story is more than an account of inventing technology. It's a blueprint for inventing inventors.”
