Dear Dr Khaleel
Solar pond can store high thermal energy as heat. This stored heat can be used in heating and air conditioning.

Dear Dr Khaleel
Solar ponds are efficient methods to store energy. It uses the gradient salty water to gather and collect the solar radiation energy as heat inside it. This heat can be used in many applications. Surely, heating spaces is an application which can be satisfied by solar pond.

It might be helpful to incorporate a phase-change material into a solar pond that undergoes solid/liquid phase change in the temperature range attained in the solar pond. Storage of latent heat in addition to sensible heat might increase efficiency of a solar-pond-powered heating system.
Dear Dr Denur
You have presented a good is a to increase the heat storage of a solar pond. However it is costs are rerely high.
Regards
Dear Dr. Denur, Dear Dr Nasser
PCM has excellent storage properties but using it is solar ponds may reveals a problem due to the large size of the pond. However, it can be used in the required application out of the pond which will reduces the costs.

You could use a pump to take suction from the solar pond and circulate the hot water in pipes inside the building for space heating and then return the colder water back to the pond to be reheated.
Hope this helps answer your question.

Dear all
A solar pond is a body of water that collects and stores solar energy. Solar energy will warm a body of water (that is exposed to the sun), but the water loses its heat unless some method is used to trap it. Water warmed by the sun expands and rises as it becomes less dense. Once it reaches the surface, the water loses its heat to the airthrough convection, or evaporates, taking heat with it. The colder water, which is heavier, moves down to replace the warm water, creating a natural convective circulation that mixes the water and dissipates the heat. The design of solar ponds reduces either convection or evaporation in order to store the heat collected by the pond. They can operate in almost any climate,

Dear all that answered my question i hope to thank you very much . can we use plastic pipe heat exchanger at the bottom of the solar pond to extract heat from it .
