As everyone knows that the sun is the largest renewable sources of energy. Its energy is available in abundant in nature. This all everyone knows. But we had a problem to entrapping this abundant energy. Also the equipments used for its trapping was found to be very costlier.
Now an method that has emerged a long back suits to be suitable to some extent. Its simply the solar ponds. This idea was researched 1987 itself. This pond offering processed heat to the dairy industries from 1993. This is located in Bhuj, Gujarat.
Here the process is very simple. Everyone knows that when you heat water it becomes light and travels upwards. The pond's temperature remains at the atmospheric temperature.This prevents the heat loss from the pond to the atmosphere.
Also salt is add to this pond, which prevents the light vapor to reach the top. The heat of the pond is trapped in it. This salt makes the vapor heavier & prevents it from rising.
There are three zones available, Upper convective zone where the salt concentration is least. Non convective zone there the salt concentration is intermediate & Lower convective zone where the salt concentration is found to be the maximum.
Its also found that the water cannot move from one zone to another, thereby acting as an insulator which not only allows the sun's energy to reach the bottom of the pond but also doesn't allow them to go off. This way it entraps the sun's energy & this can be used for various processes.
It can be made anywhere required. It will be economical if we construct these solar ponds where we the salt is available.
This way we can save our earth & natural resources. If you all have any of such innovative ideas to save our earth. You can publish then in the comments.a
