A distillation device and method of manufacturing a distillation device is disclosed. The distillation device includes at least one spiral wound membrane distillation (MD) unit. The spiral wound MD unit includes a perforated center tube concentric to a cylindrical housing and a plurality of effects spirally wound around the center tube. Each of the effects include a vapor permeable membrane, a feed spacer disposed on the vapor permeable membrane, a permeate spacer, and a heat exchange film. The permeate spacer is disposed between the vapor permeable membrane and the heat exchange film. Distillation of a feed fluid by the plurality of effects deposits a condensate fluid into the center tube.

A fluid power circuit with a switch-mode power transformer used to transfer power while keeping the pressure of power source and reverse osmosis processes relatively decoupled. The switch-mode power transformer uses the inertia of a hydraulic motor driven electric generator and switching of a hydraulic motor inlet between high and low-pressure ends to decrease the pressure at which power is being transmitted to a reverse osmosis process.

An exemplary power system utilizes turbines configured within a water intake conduit to the desalination processor to produce power for the desalination processor. Water intakes are configured to provide a natural flow of water to the desalination processor though hydrostatic pressure. One or more turbines coupled with the water intake conduits are driven and produce power for the system. The desalination processor incorporates Graphene filters to and may include a structured water system to increase the H3O2 concentration of the water prior to Graphene filters. Discharge water may be pumped back into the body of water but be separated from the intakes. A secondary power source, such as a renewable power source, may be used to produce supplemental power for the system. Power produced may be provided to a secondary outlet, such as a power grid, all above and/or underground.

The present disclosure discloses a system and a method for solar-driven photothermal seawater desalination and ion electroosmosis power generation. In the system, a first reservoir is provided with a first electrode immersed in seawater; a second reservoir is connected to the first reservoir via a cation selective nanofilm; a third reservoir is provided with a second electrode immersed in seawater, and the third reservoir is connected to the second reservoir via an anion selective nanofilm; and an adjustable sun-visor shields the cation selective nanofilm to form a first preset part of solar illumination and shields the anion selective nanofilm to form a second preset part of the solar illumination. Therefore, the cation selective nanofilm and the anion selective nanofilm are each under an asymmetric illumination to generate a temperature gradient.

The present teachings generally include parabiotic dialysis systems and techniques. For example, the present disclosure includes parabiotic liver dialysis, e.g., for use in settings with limited resources. To this end, a parabiotic liver dialysis system may include a device having a semipermeable membrane with an average pore size that allows for the passage of albumin therethrough. In such a system, a first extracorporeal circuit may connect the device to the vascular system of a first animal (e.g., a liver patient), and a second extracorporeal circuit may connect the device to the vascular system of a second animal (e.g., a human with normal liver function), where the exchange of albumin therebetween is facilitated through the device. The present disclosure also includes various safety measures for parabiotic dialysis systems and techniques, such as biometric verification systems and techniques.

Power generated by a wind turbine is applied to drive reverse osmosis (RO) desalination. Rather than discharging the brine back into the ocean, it is concentrated and modified through industrial-scale processes to produce sodium hydroxide (NaOH). Direct air capture of CO.sub.2 occurs when liquid NaOH, created from the RO desalination brine, is conveyed to the rotor hub and emitted from the wind turbine blades to react with CO.sub.2 in the atmosphere. The power of an offshore wind turbine is used for the onboard production of fresh water to supply shoreside water needs, or water may be electrolyzed to produce hydrogen while adding the vital process of CO.sub.2 sequestration to the ocean.

The invention relates to an anti-blocking seawater desalination device based on graphene filtering, comprising heating device, solar heat-collecting device, fresh water condensation heat-exchange device and thermal-expansion and cold-shrinkage control valve mechanism; the heating device can fully heat and distill seawater, the sprayed seawater is distilled by graphene heat-conduction layers to improve the distillation efficiency and avoiding blocking; the distilled water vapor enters into fresh water condensation heat-exchange device to exchange heat with seawater, increasing the seawater temperature, making full use of the heat in water vapor, and increasing water vapor condensation speed; the distilled concentrated seawater enters into the thermal-expansion and cold-shrinkage control valve mechanism, the flow of seawater entering into the heating device is controlled by the concentrated seawater temperature, when the temperature is too high, the flow of the seawater entering into the heating device increases, and when the temperature is too low, the flow decreases.

Energy may be stored by injecting fluid into a fracture in the earth and producing the fluid back while recovering power and/or desalinating water. The method may be particularly adapted to storage of large amounts of energy such as in grid-scale electric energy systems. The fracture may be formed and treated with resin so as to limit fluid loss and to increase propagation pressure. The fluid may be water containing a dissolved salt or fresh water and a portion or all of the water may be desalinated using pressure in the water when it is produced.

A water purification system utilizes an ionomer membrane and mild vacuum to draw water from source water through the membrane. A water source may be salt water or a contaminated water source. The water drawn through the membrane passes across the condenser chamber to a condenser surface where it is condensed into purified water. The condenser surface may be metal or any other suitable surface and may be flat or pleated. In addition, the condenser surface may be maintained at a lower temperature than the water on the water source side of the membrane. The ionomer membrane may be configured in a cartridge, a pleated or flat plate configuration. A latent heat loop may be configured to carry the latent heat of vaporization from the condenser back to the water source side of the ionomer membrane. The source water may be heated by a solar water heater.
