WO2010124697A3 - Floating on pontoons desalinating and electricity generating tandem power plant - Google Patents

Abstract

This invention relates to a method for desalinating sea water bellow the pond, through freezing it to Ice and isolating the Ice in a sealed tank to melt it. Aiding colder water is pumped up from different sea depths, which reaches a temperature down to 4°C, saving freezing power and controlling the quantity of Ice produced, storing the desalinated water in the pontoons, by discharging the pontoons balance balloons from salt water - The floating power plant, synchronously generates electricity, through special circuits producing the freezing coldness, as gas/steam compression circuits and the liquid(s) pumping circuits filled completely with liquid gas or filled partially with either liquid gas or other fluids like Methanol, Ethanol..., which all produce synchronously, electricity, - The flow engines connected to a generator of the said circuits are driven only by using renewable energies, such as: 1- basically the sea water thermal temperature, to discharge the freezing coldness and/or the warmness of the pond to gain additional thermal energy from sea water 2- the temperature differences between deeper and surface sea water, to create higher pressure differences driving the flow engine of the liquid gas pumping circuits, 3- aiding other renewable energies are added cheaply driving directly the compressors of gas compression or pumps of liquid gas pumping circuits, producing freezing power and producing amplified by the sea temperature heat discharged at the pond. - The pontoons of the floating power plant have to be stabilized at sea with pillars, a.- which offers the use of wind energy, just adding fans on top of the stabilization pillars b.- The suspension energy from wave and ebb and tide motions on the pontoons, offers the use of wave energy, by adding direction unifying units to the alternate flow obtained c- If solar heat exists, it is absorbed automatically, just darkening the floor of the pond. - To maintain always the optimum speed of the generators, over produced 1- "HEAT", is saved : by the additional "accelerated evaporation" desalinating water, by lowering above the tightly sealed pond the pressure to a level below 0.9 bars and using only over produced heat in the pond (higher than 30°C), 2- "ELECTRICITY", is saved: by producing hydrogen and converting hydrogen (H₂) and carbon dioxide (CO₂) to liquid methanol (H3-C-OH).
