Radical new technology Seawater Steam Engine presented in this book is a scientific and technological breakthrough with the hopes of stopping climate change. New technology can simultaneously produce energy and drinking water, using only 3 natural forces: Renewable energy sources (RES), Seawater and Gravity. In the next 15-30 years with this technology it will be possible to produce 24,441 TWh of energy and 244 km3 of drinkable water per year, which are amounts that can satisfy mankind's needs for energy and drinkable water and save up to 20 Gt of CO2. Seawater Steam Engine technology has an extremely high potential for further development and could in fact become the 'prime mover' of third, and last, industrial revolution, which essentially becomes a synonym for realization of sustainable communities.
