Salt To Store Solar Energy

A professor from the University of South Florida has devised an innovative way to harness the sun’s energy even after it has disappeared from the sky. Yogi Goswami, an internationally renowned mechanical engineer, used salt-filled ceramic balls which help convert water into steam when there’s no sunshine.

The steam then powers electricity-generating turbines. Although not a novelty when it comes to ways of storing energy, this is the first time that a way to concentrate the energy storage into golf ball-size capsules has been devised by the professor. Using this technique means that, even at high volumes, the balls take up little space, reduce costs and last much longer than other technologies so far in use.
