A fluid processor for use in a downhole pumping operation includes a fluid processing stag, a nozzle stage and a gas compressor stage. The nozzle chamber is configured as a convergent-divergent nozzle and the variable metering member is configured for axial displacement within the convergent section to adjust the open cross-sectional area of the nozzle. A method for producing fluid hydrocarbons from a subterranean wellbore with a pumping system includes the steps of measuring a first gas-to-liquid ratio of the fluid hydrocarbons and operating a motor within the pumping system to operate at a first rotational speed. The method continues with the steps of measuring a second gas-to-liquid ration of the fluid hydrocarbons with the sensor module, where the second gas-to-liquid ratio is greater than the first gas-to-liquid ratio, and operating the motor at a second rotational speed that is faster than the first rotational speed.

A downhole drill pipe may comprise a transducer disposed therein, capable of converting energy from flowing fluid into electrical energy. A portion of a fluid flowing through the drill pipe may be diverted to the transducer. After passing the transducer, the diverted portion of the fluid may be discharged to an exterior of the drill pipe. To generate electrical energy while not obstructing the main fluid flow from passing through the drill pipe, the transducer may be disposed within a lateral sidewall of the drill pipe with an outlet for discharging fluid exposed on an exterior of the lateral sidewall.

Kinetic Energy Electric Power is an ecofriendly method of producing utility-scale electricity. It does not need high pressure steam to operate, there is no need for expensive steam turbines, nor do any of its operating plants need to be placed within any particular geographical location or weather condition such as sunny, windy, near water, etc. This invention is driven by heated air flowing through a system of solar thermal panels containing mineral oil, or another suitable heat-retaining liquid, that is circulated within a closed circuit piping network through one or more thermal energy storage tanks then through heat exchangers located in one or more large heat chambers that have a chimney stack extending skyward in order to facilitate the draft of air. As the air inside the chambers is heated and expands, it is forced out the top, because of stack effect, through the chimney, thus forcing fresh air to flow in through an opening at the chambers' bottom that brings outside air in via a passageway and travels through one or more paddlewheel-like wind turbines that drive multiple large, weighted flywheels that have multiple electric generators attached to them via gear/clutch mechanisms and producing utility-grade electricity 24/7, 365.

A thermal management system for an aircraft includes a thermal bus including one or more first heat sources; a heat sink; a vapour compression system including a compressor, a condenser, a receiver, a first side of a recuperator, an expansion valve, an evaporator, a second side of the recuperator, and the compressor; and one or more second heat sources. A heat transfer fluid transfers waste heat energy generated by the first heat sources to the heat sink. A second flow of waste heat energy from the second heat source(s) is transferred to a refrigerant. A third flow of heat energy in the refrigerant is transferred to the heat transfer fluid. The compressor includes a supplementary refrigerant reservoir, and the volume of refrigerant in the vapour compression system is increased during operation when a temperature of the heat transfer fluid is at or below a temperature of the second heat source(s).
