Systems and generating power in an organic Rankine cycle (ORC) operation to supply electrical power. In embodiments, an inlet temperature of a flow of gas from a source to an ORC unit may be determined. The source may connect to a main pipeline. The main pipeline may connect to a supply pipeline. The supply pipeline may connect to the ORC unit thereby to allow gas to flow from the source to the ORC unit. Heat from the flow of gas may cause the ORC unit to generate electrical power. The outlet temperature of the flow of the gas from the ORC unit to a return pipe may be determined. A bypass valve, positioned on a bypass pipeline connecting the supply pipeline to the return pipeline, may be adjusted to a position sufficient to maintain temperature of the flow of gas above a threshold based on the inlet and outlet temperature.

In one example embodiment, there is provided a flowmeter system. The flowmeter system includes a high temperature transferring part that collects external heat energy to transfer the heat energy; a low temperature transferring part that transfers heat energy of an intake pipe; a stirling engine that produces a power based on a temperature difference between the heat energy transferred from the high temperature transferring part and the heat energy transferred from the low temperature transferring part; and a flowmeter that is supplied with the power produced by the stirling engine to measure a flow rate of the intake pipe.

A system of captive oxygen fuel reactor to efficiently generate electricity from hydrocarbon fuel utilizes a flow of oxygen and a flow of hydrogen from an electrolysis unit and a flow of carbon monoxide in order to complete a fuel oxidizer reaction within a heat exchanger unit. The fuel oxidizer reaction emits a flow of steam and a flow of carbon dioxide from the heat exchanger unit re-direct them through a steam rotary piston motor unit, a carbon dioxide rotary piston motor unit, a steam carousel motor unit, a carbon dioxide carousel motor unit, and a duel drum motor unit to generate electrical current. The exhaust gases within the system are properly discharged and stored within respective storage containers for the use of the system or other possible requirements.
