Abstract: A self-contained orbiting power plant receives and directs solar radiation as an energy source to heat the working fluid of a Rankine-type engine used to power an electrical energy generator and create a pseudo-gravity environment in which the buoyant force exists. Through the use of reflectors and alignment of the power plant with the solar radiation source, the low temperature of outer space is used as a heat sink to condense steam back into the liquid phase. The working fluid (e.g. water) is pressurized and heated to the elevated vaporization point and the expansion of the superheated steam is captured through rotation of the power plant in the microgravity environment. The steam is used to rotate an electrical generator turbine and a counter-rotation hull turbine. The steam is cooled by conductive heat transfer to a cooling fluid (e.g. liquid ammonia) which radiates excess heat to outer space, and to return the working fluid to the liquid phase for recirculation.

Abstract: A device to collect wind energy from the rooftop of a house or other building is described. The device encompasses a wind scoop, which can be moved in any direction to ‘catch’ the prevalent wind. The wind passes through conduits to a low-profile wind turbine, which is configured for maximum containment of wind and energy capture. The turbine powers a electricity generator to produce electricity. In an alternative embodiment, the turbine can be powered by moving water from ordinary municipal water lines or other sources.
