The device (10) for continuous generation of cold and heat by the magneto-calorific effect, comprises a chamber (11), divided into two adjacent compartments (12, 13), separated by a wall (14). The chamber (11) contains a rotating element (15) made from at least one magneto-calorific material, a first circuit (17a) with a first heat exchange fluid circulating therein and a second circuit (17b) with a second heat exchange fluid circulating therein. The chamber (11) is connected to magnetic device (16) for generating a magnetic field in the region of the compartment (12) in which the rotating element (15) is located. When the above is set in rotation the part thereof located in the first compartment (12) is magnetized upon undergoing an increase in temperature. On passing into the second compartment (13), the part is demagnetized upon undergoing a cooling. The heat and the cold thus generated are transmitted by the heat exchange fluids respectively to user circuits for heat (19) and cold (22) for recovery and use for ulterior purposes.

An ST-MRAM structure, a method for fabricating the ST-MRAM structure and a method for operating an ST-MRAM device that results from the ST-MRAM structure each utilize a spin Hall effect base layer that contacts a magnetic free layer and effects a magnetic moment switching within the magnetic free layer as a result of a lateral switching current within the spin Hall effect base layer. This resulting ST-MRAM device uses an independent sense current and sense voltage through a magnetoresistive stack that includes a pinned layer, a non-magnetic spacer layer and the magnetic free layer which contacts the spin Hall effect base layer. Desirable non-magnetic conductor materials for the spin Hall effect base layer include certain types of tantalum materials and tungsten materials that have a spin diffusion length no greater than about five times the thickness of the spin Hall effect base layer and a spin Hall angle at least about 0.05.

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.
