How to extract drinking water from sea water using a solar still.

Описание к видео How to extract drinking water from sea water using a solar still.

In this video I demonstrate how to build a solar still. Solar stills can be used to extract drinking water from ocean water. Under most circumstances extracting drinking water from the ocean is an extremely energy intensive process. The name for the industrial process is called water desalination. This is the complete opposite. The idea was to create a process that is as energy efficient as possible while using no external energy sources other than the sun and the night air.
