Geothermal source on-site power generation plant with computing facility and method
A method of processing electrical data and signals which comprises locating a site with a geothermal hot water resource which feeds hot water to an on-site heat engine that drives an on-site electricity generator which provides electrical power to an array of microprocessors, located in an enclosure structure, that processes data transmitted from a remote location at high speeds. The processed data is transmitted back to the remote locations at high speeds.
METHOD FOR THERMAL ENERGY TRANSMISSION USING WATER AND CARBON DIOXIDE
The invention provides a system for energy distribution that uses liquid carbon dioxide as a working fluid. Evaporation of the carbon dioxide provides cooling, and compression of the carbon dioxide gas back to the liquid state provides heat. The amount of heat transferred at both stages is sufficient to provide environmental heating and cooling. Waste thermal energy from a power plant, in the form of hot water, is fed into the system and used to drive the overall process. An underground thermal energy storage system is used to store energy flowing into the system that is in excess of the current demand.
ADVANCED REINFORCEMENT DESIGN FOR MULTIFUNCTION CONCRETE WASTEPIPES
This application discloses an advanced design method for customized RCP, (cRCP), with one or more made-to-order reinforcement cages supporting one or more wall-encapsulated heat-exchange channels, cast with special-batch (SB) concrete having additions of fine-disperse CaCO.sub.3 and particular polymer fibers; the resulting Single- and DoubleEPipe sections especially adapted for heat exchange with pipe-internal wastestreams and/or groundwater and including provisions for an optional graywater accumulator for efficient recapture of both water and energy.
Fuel cell heater system
A heater is described. The heater includes a fuel cell to produce heated air, electricity and water vapor. The heater further includes a heating element operatively coupled to the fuel cell to convert the electricity to heat and a control system operatively coupled to the fuel cell and the heating element, the control system being configured to monitor and control the fuel cell and heating element.
PROVIDING DOMESTIC HOT WATER FROM CONVENTIONAL RESIDENTIAL SPLIT SYSTEM HEAT PUMPS
In a split system heat pump cooling and heating system, an auxiliary hot water storage tank is provided as an energy storage bank. Two sets of coils run through this storage tank, a first set carrying hot refrigerant from the heat pump to deposit energy and a second set carrying hot potable water to remove energy. Valve and switch matrixes are operated at the heat pump to provide hot potable water from the energy storage bank during both normal space heating and cooling operations of the heat pump.
Solar water heating system
Systems and methods for a thermosyphonic water heating system for a storage tank. A DC heat pump receives power from a DC power source and heats water via a heat exchanger using a thermosyphonic piping system. A passive back-flushing having a cold water inlet pipe connected to the hot water return pipe draws cold water into the storage tank through the heat exchanger. A vertical array of temperature sensors distributed throughout the storage tank monitor temperature of stored water at multiple heights and a communication unit communicates monitored data to an external control device.

REGULATION SYSTEM FOR A THERMO-HYDRAULIC CIRCUIT AND CONTROL METHOD
A system for regulating a thermo-hydraulic circuit has a thermal machine, a heat exchange terminal, a carrier fluid circulation system having a delivery duct, a return duct, and a three-way valve. The system has a pump, a first temperature sensor measuring post-valve delivery temperature of the carrier fluid downstream of the three-way valve, a second temperature sensor measuring pre-valve delivery temperature of the carrier fluid, and a third temperature sensor measuring temperature of the carrier fluid downstream of the heat exchange terminal. A flow or flow rate sensor measures a mass or volumetric flow rate of the carrier fluid. An electronic control unit has a storage device in which a model function of the thermo-hydraulic circuit is stored. A processing unit calculates values of a valve control signal and a pump control signal as function of a mass or volumetric flow rate error and a carrier fluid delivery temperature error.
