This invention describes a non-imaging, non-tracking, integrally-formed solar radiation concentrator that passively concentrates both diffuse and direct solar radiation onto photovoltaic cells to produce electricity, incorporating its features into a shingle-like element useful as a roofing material and in other structural applications. The substantially transparent, solar concentrating elements of the invention may also incorporate a system to remove waste energy in the form of heat that is not utilized in the generation of electricity. The invention further provides a thermal energy recovery system including a forced convection air system for removing waste heat from the concentrating shingle assembly and using it, if desired, for building space heat or domestic water heating.

Heat pump water heater and associated control system
ActiveUS20110058795A1Maintain water temperatureDomestic stoves or rangesElectric heatingControl systemEngineering
A heat pump water heater has a tank portion, an electric heating structure for adding electrical heat to water stored in the tank, and a heat pump for adding refrigerant heat to the tank water. A control system associated with the water heater has three user-selectable heating modes for heating the tank water during a given heating demand cycle—a first mode that initially heats the tank water with refrigerant heat while the electric heat is locked out for a first predetermined period before supplementing the refrigerant heat if necessary, a second mode similar to the first mode but with a longer electric heat lockout period, and a third mode in which only the electric heat is utilized to satisfy a tank water heating demand. Illustratively, the heat pump is disposed in a compact component arrangement on the top end of the water heater tank.

This invention provides a system and method for cogeneration of electric power and building heat that efficiently interfaces a liquid-cooled electric power generator with a multi-zone forced hot water (hydronic) space heating system. The system and method utilizes an electric generator with an electric output capacity (kW) that is near the time-averaged electric power consumption rate for the building and with a heat generation capacity that is useful for meeting building heating needs. This generator is operated as the priority source of heat for the building, but normally only when there is a demand for heat in building, with the intent of running the generator for long periods of time and generating a total amount of electric energy (kWhs) that is significant in comparison to the total electric energy consumption of the building over time. The actual onsite time-variable power demand (kW) is met by a combination of the cogenerated electric power produced on site and quantities of electric power from the public electric power grid or another external power source. Hence, useful electric power is generated on site as a by-product of the required generation of heat for space or water heating. The generator is run at a speed / operating condition that is appropriate to maintaining a long operational life.
