Abstract: The portable and autonomous desalination system is an autonomous reverse osmosis (RO) desalination system utilizing power from a combination of electricity generation and storage sources that include a photovoltaic (PV) unit, a vertical-axis wind turbine (VAWT) unit, and an electricity storage unit. Electric power from PV, VAWT or storage units or a combination of these units is provided, depending upon the availability of sunlight or wind, or for night operation for water desalination using the reverse-osmosis process. The unit is portable, environmentally friendly, self-sufficient and self-sustaining in terms of supplying the electricity and fresh drinking water needs of the typical household. Multiple PV-VAWT-RO desalination units are combined together to provide fresh, clean water and electricity for communities of various sizes. A small-size, straight-bladed vertical axis wind turbine runs at very low wind speeds for urban operation.

Abstract: The lighter-than-air vehicle for shading is an airborne, movable system that provides sun shade for an open area. The vehicle is a substantially flat flying device having upper and lower surfaces, and which is filled with a lighter-than-air gas or gases, such as helium or hydrogen. The vehicle may be tethered to the ground through control wires, or may be fully autonomous and controlled by propeller fans. The required power may be provided by wire from ground, or through a portable power source, such as solar cells, mounted atop of vehicle. The vehicle has sun sensors that allow it to track the sun, and provides around the clock shaded area underneath its surface. The vehicle can also have pressure sensors and altitude sensors that may trigger an alarm in case of an emergency descent to the ground.

Abstract: The solar-powered air conditioning system is a low cost, environmentally friendly system for cooling air through evaporative cooling. The system includes a motor-driven fan for producing a directed air stream. A water delivery system is in communication with an external water supply and produces water droplets, which are delivered into the directed air stream. Evaporation of the water droplets within the directed air stream lowers the temperature of the directed air stream via evaporative cooling. The motor-driven fan is powered by at least one solar panel, which may be mounted on a water tank for holding the water supply of the water delivery system. Further, a rechargeable battery may be provided for providing power when the solar panel generates insufficient power.

Abstract: A hybrid cooling system for cooling electronic devices includes a heat generating electronic device and an endless metal belt in sliding contact with a surface of the device for removing heat by conduction. The system also includes a fan or jet and an airfoil with and without a movable surface and/or flap for simultaneously directing a flow of coolant across the electronic device and/or the endless metal belt. An additional cooling element and cooling fins are also disclosed. Further, a method for cooling such devices is disclosed.

Abstract: Movable surface planes include opposed independently movable endless surfaces over the majority of opposite sides of the planes. By moving one surface in the same direction as the fluid flow about the plane, and the opposite surface in a direction opposite the fluid flow, the flow is accelerated across the surface moving in the same direction to produce a lesser pressure, and retarded across the surface moving in the opposite direction to produce a greater pressure. The net result is a force urging the plane toward the surface moving in the direction of ambient fluid flow. The two surfaces of the present invention may be operated independently of one another, to move in the same or opposite directions and to have the same or different velocities. The movable surfaces are porous and communicate with ductwork within the structure, to provide fluid flow through the surfaces for boundary layer control.
