A conduit 4 in the form, for example, of When light 24 of the sun 19 shines on Solar battery 22, an exhaust pipe or a chimney, Stands vertically, advanta 25 electric power is obtained directly therefrom, and at the geously at the center of building structure 1, and extends Same time battery panel 22 is heated by the Sun. As a result, through room 2, ceiling 2" and roof 3. Conduit 4 includes hollow passage 23 is also heated to produce rising air Stream holes 6 and 6' near ceiling 2" of room 2. 21 by the chimney effect. This air Stream is gathered together Warm convection 9 of heat produced by heating of room by means of air circuits, as will be more fully described with 2 by artificial sources and body heat is drawn into conduit 4 reference to FIG. 7, and turns fan 11 to generate electricity. through holes 6, 6' and once inside comprises a rising air By changing Sun light to electricity through Solar battery 22 stream 10 created by the chimney effect. Rising stream 10 and power generator 12 operated by Solar heat, and therefore turns a fan 11 near the upper top of conduit 4, which in turn making more complete use of Solar energy, it is possible to operates a power generator 12 drivably connected therewith. obtain electric power with improved thermal efficiency. In this manner electric power can be obtained from power 35 Referring now to FIG. 6, an embodiment of the invention generator 12 by warm convection 9. is shown which employs triple construction power generat Conduit 4 can provide Several advantages concomitant ing equipment for further utilization of the potential of the with its usefulness in channeling rising Stream 10 upward for Sun.

An energy generation System, comprising: Having described preferred embodiments of the invention a conduit for channeling a convected flow of an air created with reference to the accompanying drawings, it is to be by a difference of heat along portions of Said conduit; understood that the invention is not limited to those precise an energy generation means responsive to Said flow of air embodiments, and that various changes and modifications disposed along Said conduit for converting energy of may be effected therein by one skilled in the art without Said air flow into another form of a uSable energy; departing from the Scope or Spirit of the invention as defined 1O in the appended claims. wherein, Said conduit is attached to a building Structure What is claimed is: with a portion of Said conduit oriented vertically and 1. An energy generation System, comprising: having an opening at a top;
a conduit for channeling a convected flow of an air created 15 wherein, a heated air vents into an outside environment by a difference of heat along portions of Said conduit; through said conduit by a chimney effect of Said an energy generation means responsive to Said flow of air convected flow;
disposed along Said conduit for converting energy of wherein, Said building Structure has a floor and a Space Said air flow into another form of a uSable energy; juxtaposed to the floor, Said conduit directing heated air wherein, Said conduit is attached to a building structure to Said Space to thereby heat Said floor; with a portion of Said conduit oriented vertically and wherein, Said energy generation means consist of a fan having an opening at a top; operated electrical generator positioned in Said con wherein, a heated air vents into an outside environment vected flow within said conduit; through said conduit by a chimney effect of Said wherein, Said conduit is a part of a Solar heating System convected flow; 25 attached to Said building Structure with a Solar panel wherein, Said energy generation means consist of a fan positioned at an exterior of Said building Structure to operated electrical generator positioned in Said con define a portion of Said conduit; vected flow within said conduit; wherein, Said conduit has at least one opening at a lower wherein, Said conduit is a part of a Solar heating System point to an interior Space of Said building Structure as attached to Said building Structure with a Solar panel an intake of a heated air of the building. positioned at an exterior of Said building Structure to define a portion of Said conduit; k k k k k
