Patent ID: 8823197

Claim:
A chimney and one or more air feeder tubes, where the air feeder tubes do not substantially gain or lose net elevation before connecting with the chimney's lower end, where the chimney gains elevation and where a rising geographic terrain substantially helps to support the chimney as the chimney substantially slopes diagonally upwards, so that relatively hot air in the chimney will rise up the chimney, the chimney and one or more air feeder tubes comprising one or more openings to the atmosphere at substantially the far ends of one or more air feeder tubes from where the air feeder tubes meet the chimney, one or more openings to the atmosphere at substantially the chimney's top end, a flow of atmospheric air or a mixture of air and other gases into the far ends of the air feeder tubes, through the air feeder tubes, up the chimney and out of the openings at the chimney's top, a device by which the gases are progressively heated by the sun's rays as the gases travel down substantial parts of the air feeder tubes to the chimney, whereby the gases are pre-heated for use in the chimney, one or more wind turbines or other devices to generate electricity from the draft generated inside the chimney by rising relatively hot gases, wherein the force of the relatively hot gases rising up the diagonal chimney drives the wind turbines or other electricity-generating devices, generating electric power, and one or more insulated chambers embedded in one or more of the air feeder tubes, which are substantially filled with earth or rock, through which the flow of air travels before the air travels up the chimney, with air tunnels or air capillaries within the earth or rock that allow substantially all small streams of the incoming air to transfer heat to or from the earth or rock while minimizing air friction, so that great amounts of heat at sunny and at warmer times will be efficiently transferred by the flow of air into the insulated chamber's earth or rock, and during dark and at colder times heat will be transferred back from the earth or rock into the air flow, whereby the chimney can run on heated air and supply electric power at hours of the day and night when immediate heat is not available from the sun or from some other source.
