Abstract: An apparatus for water reclamation includes an inlet head for admitting warm humid ambient air, a buried pipe coupled at a first end to the inlet head and sloping downward in the ground from the first end. Water condenses as the air is cooled in the buried pipe and collects in a cistern coupled at a second end of the buried pipe. A tube coupled at a lower end near the second end of the buried pipe includes a heated element extending at least partially into the tube from an upper end of the tube. Cooled air is heated by the heated element and is expelled at the top of the tube. A heater is coupled to an upper end of the heated element. The heater may be a solar collector with a Bernoulli aperture.

Abstract: Apparatus to convert LNG to gas, comprising a vaporizer having passages to pass the cool or cold LNG in heat transfer relation with warming gas flowing downwardly to discharge in multiple directions, and flow control means to control discharge of the gas flow in selected direction or directions, as a function of wind direction.

Abstract: A wind-powered ventilator includes a pressurization conduit hood mounted on the periphery of an automatic directional type or worm gear type ventilator. The conduit hood is arranged to pressurize atmospheric wind, however feeble and minimal, and conduct the wind to produce a pressurization effect, causing a pressurized wind moment to pass directionally through the ventilator, thereby achieving enhanced drafting efficiency without the intervention of artificial power sources.
