  • Patent number: 9493245
    Abstract: An air vehicle incorporating a hybrid propulsion system. The system includes a gas turbine engine as a first motive power source, and one or more battery packs as a second motive power source. Through selective coupling to a DC electric motor that can in turn be connected to a bladed rotor or other lift-producing device, the motive sources provide differing ways in which an aircraft can operate. In one example, the gas turbine engine can provide operation for a majority of the flight envelope of the aircraft, while the battery packs can provide operation during such times when gas turbine-based motive power is unavailable or particularly disadvantageous. In another example, both sources of motive power may be decoupled from the bladed rotor such that the vehicle can operate as an autogyro.

  • Patent number: 8282830
    Abstract: Devices and methods for producing purified water. The device includes a reverse osmosis subsystem, a dehumidification subsystem and a purified water storage tank fluidly coupled to the subsystems such that purified water produced by each can be locally stored. A vehicular platform, such as a ship, can be used to locate the device adjacent a supply of saline water and humid air. A saline water inlet, membrane and purified water outlet cooperate in the reverse osmosis subsystem to allow preferential passage of water relative to salt in a saline water supply, while the dehumidification subsystem includes a heat exchanger that extracts moisture from the ambient humid air. Purified water produced by each of the subsystems can be used as a potable water source.

    Abstract: A heat exchanger is provided for use in heating and cooling applications. The heat exchanger includes a heat exchange fluid, at least one heating element for heating the heat exchange fluid, and a plurality of heat exchange pipes positioned in the heat exchanger. The heat exchange pipes are filled with an uncrosslinked high density polyethylene phase change material. The heat exchanger may be used in combination with separate shell and tube type heat exchangers to provide residential heating and hot water heating. The heat exchanger may also be used in combination with an absorption air conditioning unit to provide residential cooling.

  • Patent number: 7759287
    Abstract: A composition and method of storing and releasing fuel gas such as hydrogen, methane or natural gas is provided which utilizes lightly crosslinked high density polyethylene pellets. Fuel gas is stored by placing the pellets in a reaction chamber which is heated to a temperature slightly above the crystalline melting point of the pellets, followed by the introduction of fuel gas into the chamber. The fuel gas permeates the pellets and becomes contained therein upon cooling of the pellets under pressure. The fuel gas may be stored indefinitely in the pellets at ambient temperature. When release of the fuel gas is desired, the pellets are incrementally metered into a discharge chamber and are heated to a temperature above the crystalline melting point of the pellets under a pressure from about 5 to 200 psi such that the fuel gas is released from the pellets for use. The expended pellets may then be recycled for further fuel gas storage.
