Abstract: A direct current (DC) electrical panel (DC Combiner) is disclosed which includes a plurality of input pairs of positive and negative inputs, each input pair of the plurality of input pairs is configured to provide a positive DC input at a predefined voltage and a negative DC return, each positive input is coupled to a protection circuit whereby each such positive input is isolated from other positive inputs of the plurality of input pairs, thereby generating a protected input, each protected input is coupled to a busbar, and the busbar coupled to a plurality of switched circuits via a breaker switch in line with a protected input.

Abstract: Systems and methods for implementing ejector refrigeration cycles with cascaded evaporation stages that utilize a pump to optimize operation of the ejector and eliminate the need for a compressor between the evaporation stages.

Abstract: A thermodynamic system that can approximate the Ericsson or Brayton cycles and operated in reverse or forward modes to implement a cooler or engine, respectively. The thermodynamic system includes a device for compressing a first fluid stream containing a first gas-liquid mixture having a sufficient liquid content so that compression of the gas within the first gas-liquid mixture by the compressing device is nearly isothermal, and a device for expanding a second fluid stream containing a second gas-liquid mixture having a sufficient liquid content so that expansion of the gas within the second gas-liquid mixture by the expanding device is nearly isothermal. A heat sink is in thermal communication with at least the liquid of the first gas-liquid mixture for transferring heat therefrom, and a heat source is in thermal communication with at least the liquid of the second gas-liquid mixture for transferring heat thereto.
