A master system for collocated, grid-independent energy generation and usage outside of a typical energy grid dependent system. The system uses a short-coupled delivery system between generation, storage and usage points to prevent line and system energy losses. As a result, the system generates and promotes hyper-efficient end use of electrical and thermal energy, as well as waste products produced during energy generation. Moreover, as a closed system, all waste energy can be reused and/or repurposed within the system, thereby promoting higher energy efficiencies. The versatility of the system is such that it can be implemented across any application that requires efficient energy storage and consumption, especially those involving higher levels of security and control.

A first electrode coolant path is configured to cool a first welding electrode by liquid coolant flowing from a supply path through the first electrode coolant path to a return path. A second electrode coolant path is configured to cool a second welding electrode by liquid coolant flowing from the supply path through the second electrode coolant path to the return path. Three or more valves are configured to stop or reduce liquid coolant flow through the first or second electrode coolant path and configured to stop or reduce liquid coolant backflow from the return path when the first or second welding electrode is at least partially detached. At least one valve is coupled in the first or second electrode coolant path. A drawback apparatus generates a suction force to draw liquid coolant away from a gap formed when the first or second welding electrode is at least partially detached.

The disclosure provides a fluid driving device including a casing and an oscillation film. The casing has a fluid chamber, a liquid inlet, a liquid outlet, and a vent hole. The oscillation film is movably disposed in the fluid chamber so as to divide the fluid chamber into a liquid channel and a gas channel that are not fluid-connected to each other. The liquid inlet and the liquid outlet are connected to the liquid channel, and the vent hole is connected to the gas channel. When the oscillation film oscillates, it forces liquid to flow into the liquid channel from the liquid inlet and forces gas to flow out of the gas channel from the vent hole, or it forces the liquid to flow out of the liquid channel from the liquid outlet and forces the gas to flow into the gas channel from the vent hole.

A thermal management system for an energy storage container includes an enclosed compartment containing an energy storage unit, an air temperature control unit configured to cool an interior of the enclosed compartment, and at least one inverter connected to a coolant circuit, which is separate from the air temperature control unit, and configured to be cooled by a coolant in the coolant circuit. The thermal management system also includes a radiator located outside of the enclosed compartment, the radiator being connected to the coolant circuit, wherein the coolant in the coolant circuit flows through the radiator, and at least one fan located alongside the radiator, outside of the enclosed compartment, the at least one fan being configured to blow air across the radiator to cool the coolant flowing through the radiator.
