Solar still water distillation fresnel lens, solar tracker and pcm

Mechanical Engineering

Solar energy is one of the cheapest and easily available source of energy and we can use it in so many ways. One of the application is water purification. The motivation for this project is the limited availability of clean water resources and the abundance of impure water available for potential conversion into potable water , in addition, there are many coastal locations where seawater is abundant but potable water is not available. Our project goal is to efficiently produce clean drinkable water from solar energy conversion. Our project goal is to efficiently produce clean drinkable water from solar energy conversion. Increasing shortage in fossil fuel supply and the growing need for fresh water have motivated further development of water distillation and purification by renewable energies. The use of solar thermal energy will cured the problem of getting fresh water in rural area. The simplest and direct applications of energy are the convergence of solar radiation into heat. Many type of solar stills are designed. Here in this project we designed a single basin single slope solar still. With Fresnel lens for concentrating sun light in to the solar still. Then we track sun light for this a solar tracker is used. Then we added a paraffin wax as a thermal energy storage material.Using latent heat storage materials which is paraffin wax can helps to store the solar energy during its availability and repack during off sunshine hours.A temperature measure device also used. Solar distillation is a simple technology and non requirement of highly skilled labour for maintenance and low energy consumption.
