  • Patent number: 10371127
    Abstract: Heat is collected by tributary canals formed by the space bounded by the rafters of the roof and by a thermally insulated panel at the bottom and by the roof at the top. The tributary cannels collect and concentrate solar energy that has penetrated the roof. The heat is collected by a plurality of tributary canals, in which solar heat is absorbed. The tributary canals are positioned substantially parallel with a building roofs slope such that the higher ends of the tributary canals are in the proximity of the ridge board of the roof at which a mainstream duct collects hot air arriving through the higher ends of the tributary canals. At the end of the mainstream duct an evaporator box for housing an evaporator is placed with a fan that pulls the hot air from the tributary canals and into the mainstream duct and pushes it onto an evaporator.

  • Patent number: 9453433
    Abstract: Embodiments of a system that configured as a closed loop system, with a pump, an evaporator, a power generator, and a condenser, the combination of which circulate a working fluid to generate electrical power. The embodiments can harvest residual energy in the working fluid to improve efficiency and to reduce power loss that can derive from the pump as well as other auxiliary loads (e.g., fans). In one embodiment, the system incorporates members that operate in response to the working fluid, often in the higher pressure vapor form that occurs after evaporation and/or power generation stages. These members can include mechanical elements, for example, that have motive action (e.g., reciprocate, rotate, etc.) that is useful to satisfy operating and power requirements of auxiliary loads. For the pressurization stage, these mechanical elements may embody a piston-and-cylinder arrangement (or other rotary or linear positive displacement arrangement) that generates motion that can drive the pump.

  • Patent number: 8424306
    Abstract: The Air-Water Power Generation System utilizes the temperature differential between warm air and a surface cooled by water evaporation. To enhance the temperature differential, the air that evaporates the water is first cooled by releasing heat to boil the working fluid in a boiler and then is cooled further by a counter-flow heat exchanger before the air enters the condenser where a water film is evaporating. The air then becomes colder as the water evaporates in the condenser, and this provides the cooling to condense the working fluid. Finally, the cold air flows out of the condenser and flows back through the counter-flow heat exchanger to provide the cooling of the air flowing from the boiler.

  • Patent number: 7621129
    Abstract: A geothermal power system for production of power, and in particular electrical energy, utilizing naturally occurring geothermal energy sources and a method for identifying and converting manmade and natural geological formations into a substantial source of energy and at the same time providing remediation of environmental and safety hazards. Utilizing surface air that is substantially cooler than the geothermal temperature of the subterranean cavern an induced air flow will be produced. This naturally induced air flow will be harnessed and provide the energy to the system power plants for production of electrical energy. The system includes a hydro-electric power system, a geothermal well, underground farms, heat recovery systems, a source of renewable biomass material, and air and water remediation systems.

  • Publication number: 20090217664
    Abstract: A system for generating electrical energy using a naturally occurring temperature difference is disclosed. The system provides electrical energy by thermally conduit a geothermal heat source and cold deep-level water to opposing sides of a thermoelectric element. The thermoelectric element generates electrical energy based on the temperature difference between these two surfaces.

  • Publication number: 20080202120
    Abstract: Device converting thermal energy into kinetic energy, related to the group of machines based on four-phase basic thermodynamic cycles. It uses rarefied gas in a novel three-phase cycle, of which the first phase is a spontaneous isothermal gas aggregation (0 - - - 1), equivalent to an ideal isothermal compression, followed by an adiabatic expansion (1 - - - 2), with work produced at the expense of the internal thermal energy of the gas via a gas turbine (5), and by an isobaric expansion (2 - - - 0)), where the expanded gas is reheated via a heat exchanger (6), while cooling the ambient air (7).

  • Publication number: 20080148733
    Abstract: A system and method for generating and distributing a closed loop riparian geothermal energy infrastructure. This system fills the need for the average home to tie into an existing geothermal “grid” constructed along, adjacent to or underneath a riparian body. The user may not need to invest in the geothermal infrastructure necessary outside the home to enable a geothermal system inside a home. The user, instead, is responsible for creating the section of the geothermal system that exists in the interior home infrastructure. In one embodiment of the invention, the infrastructure comprises at least one distribution flow line having a forward line for a first phase and a return flow line for circulatory second phase. The distribution flow line is coupled to any point along a main flow line. The main line flow line is buried to a sufficient depth within a riparian body for converting the first and second phases.
