An ambient water condensing apparatus that extracts water vapor from ambient air utilizing a thermoelectric device, a superhydrophobic and/or superhydrophilic radiating condensing surface and a heat sink for providing point of source irrigation or drinking water using conventional and/or sustainable energy supplies. The thermoelectric device is thermally coupled intermediate of the condensing surface and the heat sink, and in particular a cold side of the thermoelectric device is thermally connected to the condensing surface and a hot side of the thermoelectric device is thermally connected to the heat sink. The water condensing apparatus may also include at least one fan element that cools the heat sink and introduces additional air to the condensing surface. The thermoelectric device and the fan element may be powered by any suitable electrical energy source, such as by solar energy, wind energy or grid power.

The invention relates to a renewable power and/or water generator with an absorption heat transformer (AHT) providing a heat pump, an Organic Rankine Cycle (ORC) for generating power, and a coupling between the AHT and the ORC to regenerate ORC rejection heat. The AHT consists of a low pressure evaporator and a vapour absorption binary (VAB) reactor that forms the coupling between the AHT and ORC. The VAB reactor includes an absorption section with an absorber heat exchanger and a distillation section provided by a rotating centrifugal unit that includes a flooded rotating packed bed.

The present invention relates to an apparatus and a method of removing water contained in a gaseous material. An apparatus of removing water by phase-changing water contained in a gaseous material to a frost phase includes a gas inflow unit 100, a main body 200, a discharging unit 300, and a frost discharging unit 400. A method of removing water by phase-changing water contained in a gaseous material to a frost phase includes phase-changing water contained in gas to a frost phase, separating the phase-changed frost and the gas from which water is removed, discharging the gas from which the water is removed to the outside, and discharging the phase-changed frost to the outside.

A system for recovering water from air includes a base plate having an upper surface having a substantially non-reflective surface to absorb heat energy from the sun. A column is positioned on the base plate and has at least one wall through which heat energy from the sun may pass to the base plate to heat the base plate, and the base plate heats air in the column. An upper thermally conductive plate is secured at an angle between horizontal and vertical within an upper end of the column. A lower plate is secured within the column parallel to and spaced beneath the upper plate to define a flow channel between the upper plate and the lower plate. A thermoelectric cooler is connectable to a power source for cooling the upper plate. An accumulator is positioned for collecting and accumulating water that condenses on and flows through the flow channel.

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 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.

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 adjacent to the bottom of an evaporation chamber. The top and bottom of the evaporation chamber are composed of a transparent material, to allow light to pass through the evaporation chamber and reach the photovoltaic cell. The front surface of the photovoltaic cell is exposed to light, resulting in power generation by the photovoltaic cell and also heating the sides of and the air inside the evaporation chamber. Untreated water is subsequently introduced into the evaporation chamber, and a portion thereof 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.
