How to make | Solar Water Purifier / Distillation Syster with Plastic Bottles

It takes a lot of energy for water to vaporize. While a certain amount of energy is needed to raise the temperature of a kilogram of water from 0 to 100 Celcius (C), it takes five and one-half times that much to chnage it from water at 100°C to water vapor at 100°C. Practically all this energy, however, is given back when the water vapor condenses... This is the way we get fresh water in the clouds from the oceans, by solar distillation. All the fresh water on earth has been solar distilled Since one of the main goals of solar distillation is to provide a clean source of water, proper disinfection after construction is crucial. Some less intensive methods of cleaning could be use of soap or laundry detergent. A glass cover is more advantageous with respect to maintenance than a plastic cover, due to the electrostatic properties of plastic that can make it a beacon for detritus. The brine left over after thorough distillation can be harvested for sea salt, as it is now a valuable commodity in its own righ.
