Solar Powered Desalination System for Life Boat

A solar powered desalination system is developed for Life boats that can purify water from nearly any source, a system that is relatively cheap, portable, and depends only on renewable solar energy. The motivation for this project is the limited availability of clean water in Life boat. As per the SOLAS, 1.5L of water is reserved/person for 3 days, which is not sufficient. The project goal is to efficiently produce clean water from solar energy conversion inside Life boat and to add the water kept inside the life boat. Distillation requires an energy input as heat, electricity and solar radiation can be the source of energy. When solar energy is used for this purpose, it is known as solar water desalination. Solar distillation is an attractive process to produce portable water using free of cost solar energy. This energy is used directly for evaporating water inside a device usually termed as ‘solar still’. The use of solar thermal energy in seawater desalination application is implemented in the Life boats where there is specific regulation on drinking water. This desalination system provides fresh water in efficient way by using only solar energy.
