The present invention provides a power device generating greater propelling force and finds that traditional power devices do not include all propelling forces based on the fundamental core propelling force source problem. External pressure is guided to the traditional power devices since the inner speed is higher the outer speed, power consumption for overcoming fluid resistance is high, and mutual contradiction results are obtained. The unique difference between the present invention and general common sense lies in opposite fluid pressure directions; inner fluid channels and outer fluid channels with higher flow speeds are formed to generate pressure differences which guides the fluid pressure to the outside and serve as propelling force, and thus the present invention creatively finds three propelling force sources, two lifting force or propelling force sources of helicopters or airplanes driven by propellers and two propelling force sources for sufficient burning of fuel in combustion chambers of engines.

Traditional power generation with a turbine may be inefficient, costly or inconvenient. The improvement disclosed herein involves the use of two fluids. A pressurizing fluid is vaporized, pressurized and fed into a pressure cylinder holding a liquid working fluid. The pressurizing fluid forces the working fluid out of the pressure cylinder and through a liquid turbine to generate electricity or perform work. The working fluid is recycled from the turbine into another pressure cylinder for re-use. The pressurizing fluid is condensed and then also recycled back to the evaporator where it is vaporized and pressurized again. Use of a liquid rather than gas turbine makes for improved efficiency and lower cost. The use of a separate pressurizing fluid, which may be volatile, allows for convenient use where the temperature of the thermal source is limited.
