A new, low cost passive solar system that uses simple physics to help create renewable energy.
Solar ponds are a type of passive solar energy technology whereby pools of saltwater are used to collect and store solar thermal energy — making use of the natural formation of a salinity gradient in such bodies of water, whereby heat isn’t easily transferred between a high-salinity layer at the bottom of the body of water in question and a low-salinity layer on top. As a result of this naturally occurring vertical salinity gradient — known as a halocline — heat stored in the lower portions of such a “solar pond” isn’t easily lost, and can thus be used […]
