A water generating device utilizing thermoelectric cooling, also known as Peltier technology, for obtaining potable water from ambient air inside or outside a structure or dwelling, having a unique continuous duct for bringing this supply of ambient air to the device and for releasing the air back outside the device after it has been processed. This device includes a cold sink with which the incoming air is cooled below the dew point to condense the existing water vapor. The cooled air is then redirected over the heat sink which increases the efficiency and cooling capability of the device over that of using only the warmer ambient air to cool the heat sink. The rate of air flow is controlled by the variable speed of one or more fans or blowers. The fan or blower speed in turn is controlled by a device that determines the current ambient dew point by measuring the temperature and relative humidity, and the temperature of the cold sink. The incoming air flow is increased or decreased by the fan or blower, to the maximum possible flow rate without excessively exceeding the determined dew point temperature of the incoming air being processed.

A portable water-generating device for obtaining water from ambient air including a thermoelectric cooling device having a cold side and a hot side, a thermally-conductive cold sink having multiple cold sink fins of a first size thermally coupled to the cold side and a thermally-conductive heat sink with multiple heat sink fins of a second size thermally coupled to the hot side. Air-movement devices move ambient air into the device and over the cold sink fins. The ambient air is cooled as it passes over the cold sink fins causing water to condense on the cold sink fins and to collect into a collecting tray. The water is then pumped through a multi-stage filtration and mineralization system and into a dispensing water reservoir for immediate or later use.

A condensation panel to be used for harvesting water from atmospheric moisture during those times of the diurnal cycle when relative humidity is at or near 100% utilizes very localized cooling to optimize condensation on a surface whose materials promote the condensation and collection of the water. The panel is passive in the sense that it can be deployed and left in an unmaintained condition for considerable periods of time. At least one time each day, almost certainly in the morning, water harvested by the process of assisted condensation can be collected for use.

An apparatus for and method of distillation uses a high temperature thermoelectric device to heat a liquid, such as water to vapor (steam) and cool the vapor to a purified, distilled liquid. Distillation system has no moving parts, thereby increasing reliability while reducing noise and maintenance. Liquid in a container has a heating section on the container extending into it to boil it into a vapor that is fed to a condenser section disposed on the container adjacent to the heating section. A thermoelectric section provided with a Peltier effect device is interposed between the heating section and condenser section. The Peltier effect device has one side in contiguous contact with the condenser to transfer heat from it and another side is in contiguous contact with the heating section to transfer heat to it to boil the liquid into the vapor and feed the vapor through the condenser that condenses it into distilled liquid.

A method and apparatus for extracting water. The apparatus comprises a first and second cooling device and a controller. The first cooling device has a first and second side. The first side heats materials located at the first side and generates a water vapor. The second side cools the water vapor and fluids collected from a source.

The method is applicable for slow-flowing as well as fast-flowing real compressible-extendable generalized fluids and enables optimal design of convergent-divergent nozzles, providing for the most efficient jet-thrust. The method can be applied to airfoil shape optimization for bodies flying separately and in a multi-stage cascaded sequence. The method enables apparatuses for electricity harvesting from the fluid heat-energy, providing a positive net-efficiency. The method enables generators for practical-expedient power harvesting using constructive interference of waves due to the waving jet-effect.

In the present invention, a solution containing a target substance is atomized into a mist in an atomizer 1 to produce a mixed fluid of mist and air. In the collection of the mist from this mixed fluid, an air transmission membrane 51 of a pore size is used that transmits air but does not transmit the target substance contained in the mist.
