Abstract: An apparatus is provided comprising: a radiating panel mountable to a surface such that the panel is directed towards a night sky and cooled via radiation heat loss to the night sky, and air proximal the panel is cooled by transferring heat thereto which radiates the heat via the heat loss, the panel being sloped such that ambient air proximal an outer surface of the panel flows towards a lower portion of the panel as the ambient air cools, the ambient air being further cooled due to further contact with the panel as the ambient air flows towards the lower portion; a plurality of air openings in the lower portion of the panel, for the ambient air cooled by the panel to pass there through; and, an air collection space defined at least in part by the panel for receiving cooled ambient air passing through the air openings.

Abstract: A transpired solar collector chimney tower is provided. Specifically, disclosed herein is a transpired solar air heating collector device comprising: a heat absorbing root an interior space adjacent the heat absorbing root and, a plurality of air inlet openings distributed over the heat absorbing roof and configured to allow ambient air to flow from outside the heat absorbing roof into the interior space, a porosity of the heat absorbing roof due to the plurality of air inlet openings being in a range of about 0.25% open area to about 5% open area; a chimney tower extending from the transpired solar air heating collector device and connected to the interior space such that heated air in the interior space flows from the interior space through the chimney tower; and, one or more turbines positioned on a path of airflow from the interior space through the chimney tower.

Specifically, disclosed herein is a system that uses solar radiation for generating electricity comprising: a transpired solar air heating collector device comprising: a heat absorbing roof; an interior space adjacent the heat absorbing roof; and, a plurality of air inlet openings distributed over the heat absorbing roof and configured to allow ambient air to flow from outside the heat absorbing roof into the interior space; a chimney tower extending from the transpired solar air heating collector device and connected to the interior space such that heated air in the interior space flows from the interior space through the chimney tower; and, one or more turbines positioned within one or more of the interior space and the chimney tower and on a path of airflow from the interior space through the chimney tower.

Abstract: An apparatus for cooling ventilation air for a building, includes a radiating panel having an emissive surface for use on the building such that the emissive surface of the panel is directed skyward and exposed to ambient air. The radiating panel defines an air collection space between itself and the building and has a plurality of air openings for the ambient air to pass through the openings to the air collection space. A passageway extends between the air collection space and an interior of the building and is located for passage of cooled ambient air from the air collection space into the interior of the building. A fan is located for moving the cooled ambient air from the air collection space through the passageway to the interior of the building.

Abstract: Ventilation air for a building is preheated by providing on a south-facing wall a solar-energy absorbent collector panel with a plurality of air-inlet openings which communicate with air collection channels behind the panel. Outside air passing upwardly along the panel is heated by the heat of the panel which itself is heated by a combination of solar radiation and heat being lost from the interior of the building. The outside air, passing upwardly a short distance along the panel to the closest air inlet opening, is withdrawn therethrough into the air collection channel and expelled into the interior of the building.

Abstract: Ventilation air for a building is preheated by providing on a south facing wall a sunlight-absorbent corrugated collector panel with the corrugations vertical, thus defining vertical channels between the panel and the wall, and vertical grooves on the exterior of the panel. Outside air passing upwardly along the channels is heated by a combination of solar heat from the panel and heat being lost from the interior of the building through the wall. Air passing upwardly along the grooves is heated by solar heat from the panel. The thus heated air is withdrawn from the channels and grooves and expelled into the interior of the building.
