  • Patent number: 11320142
    Abstract: The apparatus described herein uses a disc wafer-type rotor featuring channels disposed around its circumference and around the interior circumference of the rotor housing specifically to induce cavitation. The channels are shaped to control the size, oscillation, composition, duration, and implosion of the cavitation bubbles. The rotor is attached to a shaft which is driven by external power means. Fluid pumped into the device is subjected to the relative motion between the rotor and the device housing, and exits the device at increased temperature. The device is thermodynamically highly efficient, despite the structural and mechanical simplicity of the apparatus. Such devices accordingly provide efficient, simple, inexpensive, and reliable sources of distilled potable water for residential, commercial, and industrial use, as well as the separation and evaporation of other liquids.

  • Patent number: 11320157
    Abstract: A natural ventilator is herein disclosed that is free of moving parts, wind-activated, rain-proof, and free of dust or smog infiltration. It is not only suitable to be a standalone natural ventilator, but is also advantageous to be used as an enhanced exhaust exit in a forced-air ventilation system, for such enclosed spaces or objects as buildings and vehicles. It can also be used as a suction generator that supplies so-called suction or negative pressure to help stabilize such building components as roof membranes by channeling the low pressure to their underside to balance the wind uplift above. The ventilator has an enhanced rainwater-proof method that serves to defend the vent system, and the space being vented, against rainwater invasion, even if raindrop trajectory becomes highly oblique from vertical as driven by strong winds.

  • Patent number: 11303244
    Abstract: A solar collection system includes an absorption refrigeration system to generate water from atmospheric moisture, and to do so without the use of an electrically operated compressor. At least a portion of the solar energy captured by the solar collection system is used to operate the absorption refrigeration cycle. The absorption refrigeration cycle provides cooling that causes water in the atmosphere to condense into a liquid that can be collected and used for various applications. As one example, the collected liquid can be used for the cleaning of the solar collection system of contaminants like dust or bird drippings. In other applications, the water can be used outside the solar collection system including, but not limited to, irrigation, drinking, and other industrial purposes.
