This project was born in April 2016 and consists of a specially designed electronic circuit that manages to extend the transfer of ions from a saline medium to convert them into useful and immediate energy. The electrodes of the salt bridge make it possible to drain energy from the salt water, (a known process), but with the electronic circuit with which it is possible to extract around 500 watts for each liter of water. The prototypes that we have developed are portable equipment weighing around 2 kilos. These teams can be scaled up to industrial production quickly. The Waterlight project can be scaled up vertically and horizontally in many ways. As goals for the immediate future, to connect several units to a central base and in this way produce and extract greater amounts of energy. A second goal is to be able to make plants on the shore of beaches to produce energy in significant quantities, continuously and for immediate use or to store in accumulators. The effluents from th
