#GE uses CO2 to solve solar #Energy’s biggest drawback
#GE: The system functions in two parts, one in which heat is collected from the #Sun and stored in molten salt. In the other, some of the surplus electricity is used to cool a pool of liquid #CO2 and turn it into dry ice. The molten salt is used to heat the solid CO2 to create a supercritical fluid — a state where CO2 will present the characteristics of both a gas as well as a liquid — which will then power an innovative turbine called a #Sunrotor.
