Why molten salt is used in solar power tower
Solar towers are non-polluting, emission-free solar power plants that can run continuously for extended periods as long as they have a way to store the free heat energy that comes from the sun. The only emissions they produce are from scattered sunlight. Modern solar tower installations.
