Patent number: 4537179Abstract: An aqueous gel comprising water and a cross-linked polyacrylamide provides a transparent, thermally insulating cover for a solar pond. Heat losses from the top of the pond to the atmosphere due to convection currents are minimized as well as losses due to evaporation. Advantage is taken of convection currents to maximize heat extraction efficiency.Type: GrantFiled: November 4, 1983Date of Patent: August 27, 1985Inventors: Ebtisam S. Wilkins, Michael G. Wilkins
