Abstract: A DC power plant generating DC power from a variety of engines including a Stirling cycle engine. The DC power plant includes a relatively small start-up power source that is discontinued after the engine is running. A method for producing DC power for a load including starting up an engine using power supplied by a relatively small power supply supplemented by a capacitor bank, providing output from the engine to a generator, producing alternating current (AC) power by the generator, converting the AC power to direct current (DC) power, disabling output of the DC power during a first set of pre-selected conditions, limiting a rate of change of current of the DC power during a second set of pre-selected conditions, reducing conducted and radiated emissions of the DC power, disconnecting the DC power from the load under a third set of pre-selected conditions, and providing the DC power to the load.

Abstract: A system including a heat exchanger with two or more channels is provided. The system includes means for one or more source channels and one or more load channels. The source channels and load channels are enclosed for containing and channeling a heat-bearing fluid through the heat exchanger. The source channels and load channels are integrated as components of complete source circuits and load circuits with the purpose of conveying the heat-bearing fluids between heat/cold loads and the heat exchanger. The system also includes means for providing thermal storage that may be used for sensible heat storage, latent heat storage, or a combination of sensible heat storage and latent heat storage. Within the system there are means for putting the source channels, load channels and thermal storage means in intimate thermal communication with one another for the purpose of exchanging heat in all flow-directions.

Abstract: A portable solar collection apparatus and system describes an apparatus and system having a solar collector apparatus having a glaze and photovoltaic panel operatively coupled to a rectifier operatively coupled to a 12-volt battery and a circulation pump, the battery is operatively coupled to an inverter. The system and apparatus includes an insulator having a cold water compartment, a luke warm water compartment, and a hot water compartment. A circulation pump moves water through the rectifier and into the hot water compartment. A mixed temperature outlet receives some of the hot water mixed with cold for discharge. The outlet may be coupled to a shower head and/or stand for discharging water.

Abstract: The invention relates to a sensible heat storage apparatus that comprises a core material that can be heated to a high temperature while it has been placed in a heat transfer fluid that absorbs essentially all the heat that is lost by any heat leakages from the core material. Accordingly, there is a very low, or almost absent overall heat loss, even though the sensible heat storage apparatus can store heat at a very high temperature. The gist of the invention is further that the high amount of heat can gradually be transferred to the HTF, which heat can in turn be put to use for domestic applications (e.g. domestic hot water and/or space heating) or for steam generation.
