Pumping liquid metal at 1,400°C opens the door for better solar thermal systems

Christopher Moore, Georgia Tech Researchers from the Georgia Institute of Technology, Stanford, and Purdue University have built a ceramic mechanical pump that can move liquid metal as hot as 1,673K (that is, about 1,400 degrees Celsius). Usually, the temperature of liquid metals that you can pump tends to cap out at 1,300K (1,027 degrees Celsius) […]

(credit: SolarReserve) On Monday the South Australian government awarded a key contract to a company called SolarReserve to build a 150MW solar thermal plant near Port Augusta. The California-based company uses giant mirrors, called heliostats, to direct sunlight […]

Three solar thermal plants in Chile could generate electricity 24 hours a day

SolarReserve The Chilean government recently gave the go-ahead on a massive solar thermal plant that is expected to produce electricity 24 hours a day, seven days a week—a considerable feat for a plant that depends solely on solar energy. The plant, proposed for a site in Chile’s Tamarugal province, would consist of three 150 megawatt […]
