The technology is based on a invention, which uses a a closed circuit comprising a thermal solar collector and a heat exchanger, in which circuit a heat transfer medium circulates, a tank which can be charged with the sea water to be treated, and in which the heat exchanger is arranged to heat and evaporate the same, a cooling surface which lies above the tank for condensation of the rising steam, and water collectors which are arranged below part regions of the cooling surface for catching the condensed water.

To achieve the goal it will require finance support and expertise networking to pass through several technology readiness levels. Because currently the project, is on an experimental proof of concept (TRL3), where a prototype, with above description, is being build.
