  Salt gradient solar pond (SGSP) is a low cost method of capturing and storing solar energy at relatively low temperatures. A SGSP has mainly three layers of water filled in a pond in an order of salinity and relative mass from the bottom to the by: 2. The salt gradient solar pond consists of three layers. The top surface layer is known as the convection zone (CZ) that is a zone of constant temperature and salinity. The thickness of this surface layer varies from to m and is formed due to upward salt transport, surface. Hot water storage has been studied extensively, particularly for space and water heating, see, for instance, Lavan and Thompson [4], Cabelli [5] Jaluria and Gupta [6] and Guo and Wu [7] Salt-gradient solar ponds have also been studied because of their considerable promise for collection and long-term storage of solar energy as reviewed by Cited by: 1.   The other ponds are still in the proof of concept stage. In this chapter solar ponds are, therefore, classified in three categories, which will be discussed in the following order: the salt-gradient solar pond (SGSP), the shallow solar pond (SSP), and alternative solar ponds (ASPs).

  This paper presents the results of a simple mathematical model for predicting the ratio of the evaporation pond (EP) area to that of a Salt Gradient Solar Pond (SGSP) area. The EP idea provides a very attractive method of salt recycling by evaporation, especially in areas of high rates of evaporation and low rates of rain as it is the case for North Africa. Pons is a pastiche of Holmes; the first book about Solar Pons was titled In Re: Sherlock Holmes. Like Holmes, Solar Pons has prodigious powers of observation and deduction, and can astound his companions by telling them minute details about people he has only just met, details that he proves to have deduced in seconds of observation.   Introduction Salinity gradient solar pond (SGSP) is an emerging cost-effective renewable thermal energy storage technique in which an artificial saline water body accumulates and store thermal energy from solar radiation. A solar pond is a pool of saltwater which collects and stores solar thermal energy. The saltwater naturally forms a vertical salinity gradient also known as a "halocline", in which low-salinity water floats on top of high-salinity water. The layers of salt solutions increase in concentration with depth. Below a certain depth, the solution has a uniformly high salt concentration.

Salinity-gradient solar ponds are of interest as a means for collecting solar energy and storing it as heat for such low-temperature applications as space heating, industrial water heating, and crop drying. Joyce, A., and Valle, L. (), “A Salt Gradient Solar. Another use of the output from a salt gradient solar pond is to operate a low-temperature distillation unit to desalt seawater, such as MSF (see Chapter 8, Section Chapter 8 Section ). Such systems operate at a top temperature of 70°C, which can easily be obtained with a solar pond. The new power-generating facility is a solar pond In order to take advantage of the heat stored in the salt gradient pool, Ormat engineers utilize a three-cycle (evaporation, drive, and.
