Jet Propulsion Laboratory (U.S.). Solar Salt Pond Power Project.

During the 1960s, salt gradient solar ponds were built and put into service in various countries of the world. Salt gradient ponds are typically large bodies of salt water, 2.5 to 5-m deep. The ponds, depending on size and depth, are capable of storing tremendous amounts of thermal energy and, therefore, can supply energy on a continuous 24-hour/day basis.

The most notable ponds were located on the shores of the Dead Sea in Israel near Ein-Bokek, at Miamisburg, Ohio, and at Albuquerque, New Mexico. A large solar pond plant experiment was also planned at the Salton Sea in Southern California.
