Abstract
Abstract An air pressure differential energy generation system comprises a stack for conduction of air from a high to a low atmospheric pressure level. A vapor injection device within the stack provides a method of filling the stack at least in part with water vapor. A heat exchanger is provided at the high atmospheric pressure end of the stack. A turbine is coupled to the heat exchanger and is impelled by warmed air. An electrical generator is coupled to the turbine to provide electrical power.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
61 words
An energy-generating system comprising: a stack having open lower and upper ends for receipt and discharge respectively of air at relatively high and low atmospheric pressures; means heating and humidifying the air within said stack adjacent said lower end inducing an upward flow of air in said stack; and a turbine mounted in said stack and driven by said air flow.
Claim 2
Dependent Claim
61 words
An energy-generating system comprising: a stack having open lower and upper ends for receipt and discharge respectively of air at relatively high and low atmospheric pressures; means heating and humidifying the air within said stack adjacent said lower end inducing an upward flow of air in said stack; and a turbine mounted in said stack and driven by said air flow.
Claim 3
Dependent Claim
17 words
The structure of claim 1, said means comprising a heat exchanger and a solar heater connected thereto.
Claim 4
Dependent Claim
17 words
The structure of claim 1, said means comprising a heat exchanger and means conducting geothermal fluid thereto.
Claim 5
Dependent Claim
21 words
The structure of claim 1, and water collection means adjacent said upper end for recovery of condensate from air discharged thereat.
Claim 6
Dependent Claim
22 words
The invention as stated in claim 1, including heat insulating material attached to and circumjacent at least a portion of the stack.
Claim 7
Independent Claim
36 words
The method of generating energy comprising: heating and humidifying air within and at the lower end of a stack to induce an upward flow of air therein; and coupling a turbine impeller to said air flow.
Claim 8
Independent Claim
36 words
The method of generating energy comprising: heating and humidifying air within and at the lower end of a stack to induce an upward flow of air therein; and coupling a turbine impeller to said air flow.
Claim 9
Dependent Claim
20 words
The method of claim 6, and recovering the condensate in the air at the upper discharge end of said stack.
