Abstract: In a preferred embodiment of the invention, rotatably adjustable elongated cylindrical solar collector plate cells, rotatable around the elongated axis thereof for adjusting angle of incidence of exterior light rays from the sun to the surface of the collector plate, are mounted upon a roof with water flow therefrom being channelled below an insulated ceiling downwardly for alternate flow as between parallel flow paths alternately selectively to and through concrete slab conduits having copper tubing directing heated water therethrough, and the parallel flow conduits through a layer of rocks beneath the concrete slab, the concrete slab being a part of the floor structure of the dwelling and the layer of rocks being a reservoir sink therebeneath, flow being directed dependent upon differential temperature of the upper floor surface of the concrete slab, such that space within supporting wall room space defined between the ceiling and the floor is economically heated devoid of excessive room temperatures and wi

Abstract: In a preferred embodiment of the invention, a dwelling structure includes a floor heating structure including copper piping embedded within a concrete slab having insulation thereunder, having hot water circulated to the concrete slab conduits from a solar cell unit arranged along an upright outer wall of the dwelling at an elevation substantially beneath the floor heating structure and with a hot water containing reservoir vessel located at an elevation substantially above the floor heating structure in flow series in closed circuit for flow from the vessel to the floor heating structure downwardly to a lower portion of the solar cells and upwardly from an upper portion of the solar cells to the reservoir vessel, by heat convection flow, the solar cells being arranged substantially along the upright outer wall of the dwelling, and the individual cells being cylindrical rotatable cells rotatable around the elongated axis thereof, adapted such that the angle of incidence of sunlight rays is adjustable intermit

Abstract: In a preferred embodiment, an electrically driven fan blows ambient temperature-air across heat exchanger heat-exchanging tubes for the taking of heat from the air into gaseous freon 12 which warmed gas is thereafter further heated by heat of compression when passed through a compressor pump, another part of the combination, the total heat of which is heat-exchanged in isolated (separated) heat exchange relationship with another closed cycle of freon 11 in a condenser boiler adapted to vaporize the freon 11 which is channeled to a gas turbine drivably connected to an electric generator for the generation of electricity, the extraneous and/or waste heat energy emanating from around the turbine being collected by a heat exchanger and coolant thereof which turbine coolant is, in the heated state, channeled to another heat exchanger tubing in separate closed cycle, over which tubing the fan also blows to both cool the heated turbine coolant and the thereby warmed air thereafter striking the freon 12-containing he
