A magnetic drive, seal-less combination axial air and water pump includes a housing having an inlet and an outlet at least one impeller mounted for rotation within the housing, and a magnetic drive surrounding the first rotor and the second rotor, the magnetic drive being configured to transmit torque to the first rotor and a second rotor at a location radially spaced from a central axis of the first rotor and the second rotor.

A system for generating electrical power may include a flowline having an inlet that receives reservoir fluid at a first pressure, an outlet that outputs the reservoir fluid at a second pressure, a first flow path between the inlet and the outlet, and a second flow path between the inlet and the outlet, in parallel with the first flow path. The difference between the first pressure and the second pressure may include a pressure differential, and the system may include a valve that adjusts the pressure differential. Additionally, the system may include a turbine disposed along the second flow path that generates mechanical energy from a flow of the reservoir fluid induced by the pressure differential, and the mechanical energy may be converted to electrical energy.

Embodiments of the present disclosure relate to a device for thermoelectric storage that may include main pressurized tanks that may contain hydraulic fluid, propellant fluid, and liquid communications. Further, the pressurized tanks may be equipped with hydroelectric conversion assemblies and heat exchange systems. In some embodiments, the device may include mobile physical separations between fluids, hot or cold thermal reserves, and secondary tanks equipped with pipes.

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.
