Abstract
An atmospheric water vapor extraction power generation device includes a hygroscopic solution, a hygroscopic solution reservoir, a circulation pump, a water vapor permeable barrier, a second evaporation heat exchanger, a first condensation heat exchanger, a steam ejector, a pressurized water driven generator, and condensed water reservoir. The pump supplies pressurized water flow thermally coupled to hygroscopic solution contained within reservoir. The hygroscopic solution absorbs moisture from ambient air through water vapor permeable barrier with the absorption of water, the hygroscopic solution decreases in density which causes it to rise towards the top of reservoir. Heat of ambient humidity condensation into the hygroscopic solution is coupled by second evaporation heat exchanger to the water contained within conduit. The heat of condensation of ambient humidity into solution is used as heat of evaporation of water contained within conduit to generate steam.
