The starting and controlling system is comprised of one or a combination of any two or more of a refrigerator, a circulating pump and a heat exchanger. The method comprises the following operation steps: filling the device with a working medium; activating the starting and controlling system; after having been pressurized under liquid state, the working medium absorbing heat and being gasified, entering the gas pipe, and generating the high-speed gas flow. The method may utilize a low quality heat source to convert a low-speed gas flow into a high-speed or extremely high-speed gas flow with relatively high use value. Thus, thermal energy carried by the fluid in the nature may be converted into mechanical energy efficiently.

  • Patent number: 9488388
    Abstract: A method for operating a geothermal system is provided to optimize heat exchange between a geothermal loop and a heat pump load loop. The flow through the earth loop is adjusted to meet current thermal demand of a heat pump array, so as to reduce the electrical demand of the earth loop circulator when heat pump thermal demand is low. The speed of the earthloop circulator adjusts to meet the operating conditions of the heat pumps and earth loop, thereby permitting efficient laminar flow whenever possible, as long as thermal demand is met. Specifically, if flow in the earth loop transitions from turbulent to laminar, this method insures that the current thermal demand of the heat pumps is met, and if not, increases the earth loop circulator speed to meet current thermal demand, otherwise maintaining laminar flow.

    Abstract: Solar/gas hybrid concentrating solar power (CSP) systems and methods of using the CSP systems are described. The hybrid CSP systems are highly efficient due, at least in part, to a solar segment comprising a first heat transfer fluid and a thermal storage segment comprising a second heat transfer fluid. The second heat transfer fluid heat exchanges with a steam segment to produce steam that drives a steam turbine. Thus, the solar and thermal segments perform the “heavy lifting” of producing steam from water. Once the steam is produced, it enters a superheater of the steam segment. The superheater, which does not heat exchange directly with the thermal storage segment, is heated by a gas turbine positioned downstream from the thermal storage segment.

Using air or water as a high temperature heat source, an expander generates cryogenic liquid as a low temperature heat source, using natural gases (such as N2, He, Air, CO2 etc.) as a working fluid, based on methods of cryogenic working fluid thermodynamic—refrigeration cycle and frost-free two stage heat exchange cycle.

  • Publication number: 20140150448
    Abstract: A method of and apparatus for producing electricity, hydrogen gas, oxygen gas, pure water using a geothermal heat are disclosed. A low voltage (such as less than 0.9V) is applied to a prepared solution containing hydrogen generating catalysts to generate hydrogen and oxygen. The hydrogen and oxygen are used to drive a gas turbine to generate electricity. The oxygen and hydrogen are combusted to generate heat and pure water. This process is advantageous in many aspects including desalinating salt/sea water using geothermal heat.

  • Patent number: 8713940
    Abstract: A method of using geothermal energy to produce electricity by lowering a geothermal generator deep into a pre-drilled well bore below the Earth's surface. A self contained geothermal generator includes a boiler, a turbine compartment, an electricity generator, a condenser and an electric cable. The condenser includes a distributor chamber, a peripheral chamber and plurality of tubes disposed within the peripheral chamber. The peripheral chamber of the condenser surrounds the turbine, electric generator and distributor chamber departments and is cooled with a separate closed loop system. The condenser cools and converts exhausted steam back in liquid state and returns it back into the boiler for reheating. Water contained within the boiler is converted to high-pressure, super heated steam due to heat from hot rocks contained within a pre-drilled well bore. The steam is used to produce electric energy which is transported up to the ground surface by the electric cable.

  • Patent number: 8658918
    Abstract: A fast heat transfer device is provided. The device dissipates heat and generates power at the same time. A liquid flow is used to absorb heat for forming a vapor gas flow; then, the gas flow drives a blade turbine and a power generator; and, finally, the gas flow is cooled down to become the original liquid flow for recycling. Thus, the present invention dissipates heat and generates power simultaneously with a minimized size and a reduced cost together with energy conservation.

    Abstract: A closed-loop, solid-state system generates electricity from geothermal heat from a well by flow of heat, without needing large quantities of water to conduct heat from the ground. The present invention contemplates uses for depleted oil or gas wells and newly drilled wells to generate electricity in an environmentally-friendly method. Geothermal heat is conducted from the Earth to a heat exchanging element to heat the contents of pipes. The pipes are insulated between the bottom of the well and the surface to minimize heat dissipation as the heated contents of the pipes travel to the surface.

    Abstract: The disclosure describes trench-confirmable geothermal reservoirs that can snugly abut trench walls (that may be of virgin, compacted earth) for facilitating heat exchange and flow liquid from one lower end to an opposing top end, and vice versa, depending on desired heat exchange. The direction can be reversed for summer and winter heat/cooling configurations. A series of the reservoirs may be used for appropriate heat transfer. The water volume of the reservoirs is relatively large and slow moving for good earth heat conduction.
