MIT startup Fourth Power, founded by Prof. Asegun Henry, has developed a solar cell that generates its energy through built-in solar panels powered by hot graphite, writes Hiawatha Bray for The Boston Globe. “The Fourth Power system can be heated up using renewable energy, like wind or solar power, at times when these resources are cranking out surplus power,” writes Bray. “[T]he Fourth Power technology could become a preferred method of providing extra power to electrical grids during periods of peak demand.”
