In the salt-gradient solar pond the density gradient is established by using dissolved salt. In principle, any inorganic salt can be used. However, some desirable characteristics for the usable salt are that it must be (1) cheap and readily available, (2) soluble in water without significant reduction of optical transmission, and (3) safe to handle and nonpolluting to the local air and ...
