Claim Text:
1. A clean energy generation system, comprising at least one energy generation unit, each of which comprises: a wind tunnel, including a contraction section, a test section and a diffuser section; said contraction section, said test section and said diffuser section are arranged in tandem; and said test section is connected to said contraction section and said diffuser section respectively; wherein said wind tunnel has a tunnel contraction end and a tunnel diffuser end; an air/gas turbine, located in said test section or said diffuser section; a generator, coupled to said air/gas turbine; at least one heating device, for preheating the air/gas flowing through said at least one heating device; wherein said at least one heating device is located in said contraction section, wherein each of said at least one heating device is a heat pump, wherein said heat pump includes a heat source and a heat sink, wherein said heat source is disposed outside of said wind tunnel, wherein said heat sink is located in said contraction section or in said connecting tube, wherein said heat source delivers the heat of ambient air/gas or geothermal heat to the destination that is said heat sink, such that said heat sink has the energy to preheat the air/gas flowing through said heat sink; and an air/gas compressor, for compressing the air/gas flowing through said air/gas compressor, wherein said air/gas compressor is located in said contraction section, and said air/gas compressor is: (1) between said at least one heating device and said air/gas turbine or (2) located in said diffuser section; wherein said air/gas turbine is driven by the preheated and compressed said air/gas such that said generator is driven to generate electricity; wherein the power produced by said air/gas turbine is more than the sum of the power consumed by said air/gas compressor, the power consumed by said heat pump and the power of net friction loss.
