Abstract: A solar water heating system, including: (a) a solar heating collector, having: (i) an array of convex lenses; (ii) a panel disposed below the array of convex lenses, wherein the array of convex lenses focuses sunlight on the panel to heat areas of the panel; (iii) a fluid chamber disposed below the panel; and (iv) a plurality of members extending from the panel into the fluid chamber to transfer heat from the panel into fluid in the fluid chamber; (b) a fluid reservoir; (c) a fluid inlet line for moving fluid from the fluid reservoir into the fluid inlet of the solar heating collector; (d) fluid outlet line for moving fluid from the fluid chamber of the solar heating collector to the fluid reservoir; and (e) a pump for moving fluid cyclically through the fluid chamber of the solar collector and the fluid reservoir.

Abstract: A system for heating and cooling a main floor of a building, including: a building having an attic, a main floor and a crawl space; an attic air blower system for moving attic air into the main floor; and a crawl space air blower system for moving crawl space air to the main floor, wherein (i) the attic air blower moves air from the attic into the main floor when the crawl space air blower moves air from the main floor through the crawl space to the exterior of the building; and, (ii) the attic air blower moves air from the main floor through the attic to the exterior of the building when the crawl space air blower moves air from the crawl space into the main floor.
