摘要： An electrical power system for a resource extraction system includes a thermoelectric generator assembly configured to couple to a wall of a fluid containment structure. A portion of the thermoelectric generator assembly is configured to be disposed within an opening in the wall that extends through the wall to a cavity within the fluid containment structure. In addition, the thermoelectric generator assembly includes a thermoelectric generator configured to be in thermal communication with a fluid within the opening and with an environment external to the fluid containment structure. The thermoelectric generator is configured to generate electrical power in response to a temperature differential between the fluid within the opening and the environment.

摘要： A triboelectric film and its laminate that utilize a conductive primer are provided. The triboelectric effect is a type of contact electrification such that with a suitable configuration, a current may flow from one region to another. When decorative triboelectric films are touched, electrical charges are built up and the generated electrical charges between a human body and films flow through a conductive primer. This system based on the triboelectric effect and the conductive primer can provide electrical functions to decorative film products without there being any large changes.

摘要： Apparatus, method(s), and system(s) according to which electric power is generated in one or more coils by rotating a magnetic field generated by one or more permanent magnets. The one or more coils are connected to a collar. The collar is positioned downhole in an oil and gas wellbore. The one or more permanent magnets are connected to a rotor positioned within an internal passageway of the collar. A fluid is communicated along the internal passageway of the collar. The rotor, and thus the magnetic field generated by the one or more permanent magnets, are rotated using the fluid communicated along the internal passage.

摘要： A control circuit for an electrostatic machine includes a current source or sink, an inductor, a switching network coupled between the current source or sink and the electrostatic machine, and between the inductor and the electrostatic machine. A controller is configured to automatically cause the switching network to connect the current source or sink to the electrostatic machine each half-cycle of a periodically alternating polarity. At each polarity alternation, the electrostatic machine is isolated from the current source or sink for a first period of time. At each polarity alternation, the inductor is connected to the electrostatic machine for a second period of time while the electrostatic machine is isolated from the current source or sink, and then disconnect the inductor from the electrostatic machine.
