Claim:
1. A method of generating a high-speed gas flow, in natural environment, that involves utilizing a device comprising a gas pipe, a circulating pipe, a guide pipe, and a starting and controlling system, wherein the starting and controlling system comprises a refrigerator, a circulating pump, and a heat exchanger; wherein the gas pipe makes a working medium in gaseous state be condensed into liquid state and be guided into the circulating pipe by necking the gas pipe to vary the diameter thereof or by additionally providing a gas-liquid separation device and a flow guiding device; wherein the guide pipe guides the working medium in gaseous state from the circulating pipe into the gas pipe in a direction toward an outlet of the gas pipe, wherein the working medium is anew circulated to enter the gas pipe after absorbing heat by passing through the starting and controlling system; and wherein the method comprises: filling the device with the working medium; activating the starting and controlling system; and after having been pressurized under liquid state, the working medium absorbing heat from the natural environment and being gasified, and entering the gas pipe, to generate the high-speed gas flow.
