The Seawater Greenhouse is a unique concept which combines natural processes, simple construction techniques and mathematical computer modelling to provide a low-cost solution to one of the world’s greatest needs – fresh water. The process uses energy from the sun and cooling from the ocean to enable year-round cultivation of high value crops.

Designer and inventor Charlie Paton came along to present the development of the seawater greenhouse which has had several trials including the Middle East, the Maldives and Gran Canaria.
