Liquid battery could charge green energy

Liquid battery could charge green energy

NEXT STAGE: Inexpensive batteries made from liquid metal could store electricity from solar panels and wind farms, and then distribute the electricity when needed. (Photo: tarczas /Shutterstock) Engineering professor Donald Sadoway on March 1 used an old-school chalk board at the prestigious TED gathering to write the formula for a liquid battery that could one day cut the need for new power plants. "The way things stand, electricity demand must be in constant balance with supply," Sadoway told the tech-savvy audience in southern California . Inexpensive batteries made from liquid metal could store electricity from solar panels, wind farms, or existing generation facilities and save it for when it is most needed. That would be a major change from today's consume-it-now-or-lose-it systems. "The battery is the enabling device here," he said. "With it we could draw electricit...
