Abstract: This invention provides a simple and energy-efficient process for obtaining water from air through better use of the solid desiccants using a high heating cycle in a confined space, applying minimal air flow and avoiding the use of a chilled condenser plate. The process of obtaining water in this invention consists of the production of water using, in one embodiment, a rotating drum covered with a desiccating material, a device that generates heat in a confined space, and a collection chamber. The process begins with charging the adsorbent material, which captures water vapor from the environment. Then, a discharging stage occurs through which an area of the desiccated material is exposed to controlled heating in a confined space, allowing the trapped water vapor to be released from the desiccant. A very light air flow may also be applied to increase the draw of the water vapor toward the area of condensation.

Abstract: The invention provides wind energy use. One application provides wind energy use for water harvesting from natural humid air. The method is based on changing thermodynamic state parameters of ambient wind air portions passed through a device comprising convergent-divergent and wing-like components. Those components transform the ambient wind portions into fast and cooled outflowing air portions. A decrease in static pressure and temperature triggers condensation of water-vapor into water-aerosols. Another application of the method provides an effective mechanism for harvesting electrical energy from naturally warm air using renewable wind energy, including the wind inertia, internal heat, and potential energy stored in the air mass in the Earth's gravitational field. The electrical energy harvesting mechanism is also applicable to use of natural renewable energy of streaming water.

Abstract: A water vapor ejector comprises a desiccant disposed in a communication path to a green house enclosure. In the day time and under sunlight exposure, the green house enclosure heats up, which dries the desiccant and generates a flow to the outside ambient through a pressure difference.

The desiccant traps the moisture within the flow, ensuring a moisture-free enclosure. The cycle re-starts in the next morning when the enclosure heats up. The diurnal cycle removes the water vapor present in the enclosure and delivered to the exterior of the enclosure.
