Study: Running Sun Power Plant With Molten Metal May Be Cheaper

Power plants that work with concentrated solar power use special molten salt to convert the sun’s heat into steam which turns the generators that produce electricity. Researchers at the Georgia Institute of Technology say using molten metal instead of salt may increase the efficiency of the generators. The innovative design was presented at the recent energy summit in Washington. While water circulates in this scale model of a concentrated solar power plant, a full-size plant uses molten...
