1. ‘ Inexhaustible Source…’

2. OBJECTIVES…  To decrease the use of non- renewable energy sources by using solar energy.  To solve the problem of “GLOBAL WARMING”.  Economical Beneficial.  Multi Applications.

3. PRINCIPLE…  When the sun rays heat up the water, this heated water being lighter, rises to the surface and loses it’s heat to the atmosphere.  While in ‘SOLAR POND’ technology, because of the salty layer of water... Fresh Salty (5%-10%) Very Salty (20%) Heat loses 1.Connecting Layer (10-15 cm/1m) 2.Non connecting / Insulator Layer (50 cm) 3. Storage Layer (35-40 cm)

4. HOW IT WORKS…? Fresh Water (atmospheric Temp. ) Rein Forced Rubber Liner Insulating Plate Heat Exchanger Drive Fluid

5. APPLICATIONS…  Other than process heating, thermal energy collected in a solar pond can be used in many more applications.  Process heat can produce hot air for industrial and space heating applications.  The heat contained in a solar pond can be used for cold storage of food products and also for air-conditioning. (KUTCH)  The hot brine can also generate electricity, using an organic Rankine cycle engine. (ISARIAL (150kW, 5MW**) )

6. ADVANTAGES…  The approach is particularly attractive for rural areas in developing countries.  Even when covered with a sheet of ice and surrounded by drifts of snow, the El Paso Solar Pond's lower zones produced temperatures of 154°F -- hot enough to generate electricity.  Coast for generating electricity is $2000 per Generated Kilowatt.
