Abstract:
1. A system for capturing heat energy from waste gas comprising: a chimney flue stack for conveying exhaust gases from a combustion space; a solar heat collecting sphere located directly above said chimney flue stack, said solar heat collecting sphere comprising at least one spray nozzle connected to a liquid supply line; a heat exchanger; a hot gas return line placed inside said chimney flue stack, said hot gas return line coupled to said solar heat collecting sphere and a refrigerant compressor, wherein said refrigerant compressor delivers refrigerant gas from said solar heat collecting sphere to said heat exchanger; said liquid supply line centrally located inside said hot gas return line for supplying said refrigerant to said solar heat collecting sphere for conversion to a refrigerant gas; a flange located at a base of said solar heat collecting sphere, wherein said flange allows for complete rotation about a vertical axis for maximum solar heat absorption; wind baffles located below said solar heat collecting sphere to cause an upward wind action; and and air supply for passage through said heat exchanger to heat a desired location.
