Solar Ponds: Research, Applications and Development

摘要

This report briefly describes selected research in solar brine ponds, chiefly in the United States and Israel. It concludes that solar ponds are technically feasible and can be economically competitive. Salts used may be sodium-chloride, magnesium-chloride, borax, disodium phosphate, or sodium sulphate. PVC pipes and heavy duty plastic liners are used to prevent corrosion, but leak detection is difficult. Stainless steel instruments are used. Shallow solar ponds are market ready, but salt gradient solar ponds are still on the fringe of market readiness.
