Abstract: A solar engine, which is vertically aligned along an interior portion of a building, is heated by solar radiation. The solar engine includes a warm air chamber at an upper portion of the solar engine and a hollow core positioned below the warm air chamber. Habitable spaces are positioned around the outside of the core toward an exterior of the building.
