Gradiant, an MIT startup founded by Anurag Bajpayee PhD ’12, S.M. ‘08 and Prakash Govindan PhD ’12, has developed an energy efficient system that purifies water by mimicking natural rainfall cycles, reports Aaron Pressman for The Boston Globe. “Nature has the advantage of having all the surface area of the oceans available freely and a free source of energy from the sun,” Govindan said. “We have to engineer this into a compact, highly efficient, and energy-efficient industrial device.”
