A Review to Improve the Productivity of the Hemispherical Type Solar Sill

Abstract

Water is the basic need for sustaining life on the earth. With the passage of time due to technical usage and their waste disposal along with ignorance of human being caused water pollution, which led the world to water scarcity. To resolve this problem Solar Distillation is one of the best Techniques. But, due to its lower productivity it cannot be commercial in the market. So that Lots of work can be done to improve the solar still efficiency or productivity. With the help of past research work we can conclude that if we are using flat circular based absorber type hemispherical solar still than its productivity will going to be increased.
