The present disclosure describes an apparatus that may be used to generate desalinated water from a supply of untreated water using a photovoltaic cell. The front surface of the photovoltaic cell is partially enclosed to form an evaporation chamber. The front surface of the photovoltaic cell is exposed to sunlight or another light source. This exposure results in power generation by the photovoltaic cell and also heats the air in the evaporation chamber. Untreated water is subsequently introduced into the evaporation chamber. Upon contacting the heated air and the front surface of the photovoltaic cell, a portion of the untreated water evaporates to generate water vapor. The water vapor is then removed from the evaporation chamber and transported to a condensation chamber. The water vapor is cooled in the condensation chamber to yield desalinated water.

A system for recovering water from air includes a skirt supported by legs and at least one interior wall suspended from the skirt. At least one exterior wall extends from an accumulator and is spaced apart from and substantially parallel to the at least one interior wall, thereby defining a flow channel between the at least one interior wall and the at least one exterior wall. At least one thermoelectric cooler (TEC) is connectable to an electrical power source for transferring heat from a cool side of the TEC to a warm side of the TEC, the cool side being positioned on the at least one interior wall, not in the flow channel, for cooling the at least one interior wall, the at least one interior wall defining a condensing surface proximate the at least one TEC.

The disclosure provides systems methods and apparatus for purifying water. A purification device includes a heating vessel adapted to receive impure water and output water or water vapor. The device further includes at least one heating element arranged outside and in thermal contact with the heating vessel, configured to provide heat to the impure water. The device also includes at least one heat exchanger to exchange heat between the impure water and the water vapor to raise the temperature of the impure water. In some example implementations, the at least one heating element can include a Peltier cell.

A water purification device comprising a pre-purified water reservoir for storing pre-purified water, a water vapor chamber for receiving water vapor generated from heating the pre-purified water in the pre-purified water reservoir, a condensation chamber for receiving the water vapor and condensing the water vapor into purified water, and a Peltier device comprising a hot side and a cold side. The hot side of the Peltier device heats the pre-purified water into water vapor and the cold side of the Peltier device condenses the water vapor into purified water.

An apparatus, system, and method for the extraction of water molecules from the air includes a combination of electrical mechanisms and materials engineering. With the help of hydrophobic and hydrophilic materials on an array of thermally conductive and electrically insulated materials, the extraction of water from the air is significantly increased. A combination of hydrophobic and hydrophilic materials and an electric field gradient moves the water molecules towards the collection system thus speeding up the water formation process. This also inhibits the re evaporation of the water droplets.

An atmospheric water harvesting generator includes an adsorbent with a nanopore structure and a moisture-condensing substrate with an amphiphilic structure such that water can be efficiently harvested from the atmosphere even in a dry climate, the generator is easy to operate with little power, and the flow of air can be controlled with a simple control to efficiently and continuously harvest water.
