First, it is important to realize a freshwater supply to prevent global desertification caused by human activities. For simplicity, let us consider the motion of a dry air mass of unit mass existing in the atmosphere under static equilibrium, where the temperature lapse rate is equal to the dry adiabatic lapse rate r (g/Cp). g is the acceleration of gravity at the earth's surface. Cp is the specific heat at constant pressure (approximately 1 kJ (K −' kg −' ) for dry air. The value of the dry adiabatic lapse rate is 0.00976 K/m. The temperature of the atmosphere.

T6 An atmosphere with values close to the altitude distribution of temperature and pressure expressed by the above equation is observed when a minute downdraft exists, for example in an atmosphere in an anticyclone.

(6) When the air mass is lowered in cycle 4, the temperature of the air mass is equal to the surrounding atmospheric temperature. Air masses do no work. The thermal efficiency of this heat engine is Am/AQ=rh/To=(To-T+ 1/To
(7) For example, if an air mass existing on the sea surface with a temperature of 300 K is raised to an altitude of 5 km, *efficiency is 16% when raised to an altitude of 10 km. Thermal efficiency is 32%. Next, we will consider the case where an air mass that is warmer than the surrounding area is introduced into the interior of a pressure-resistant pipe that extends upward. In this case, two methods of air mass introduction described in a and b below are possible. a. If the pressure at the top of the tube is equal to the pressure of the surrounding atmosphere, the temperature of the spirit inside the tube is higher and less dense than the surrounding atmosphere. Therefore, at the bottom of the tube, the pressure inside the tube is relative to the atmospheric pressure. The pressure becomes low. here. Consider the following heat engine that extracts wind energy. The altitude distribution of the temperature and pressure of the surrounding atmosphere is expressed by the formula (1). (21
．． Suppose that it is given by (3), 1. The dry air mass present at z=o is heated and its temperature is set to T, =T. 10 Let ΔT be. This air mass is introduced into the tube. 2.

(9) The wind energy generated by this tube heats the ground atmosphere with a temperature of 300 K and a pressure of 1 atm to 330 K, and reaches an altitude of 5 km. When operating with a flow velocity of 10 m/s at the bottom of the pipe, approximately 40 million kW of wind energy can be obtained.Wind energy is converted into electrical energy with high efficiency.In addition, the pressure at the top of the pipe and the surrounding atmospheric pressure The pressure difference between

! The thermal efficiency of the leapfrog. The wind energy generated when the cross-sectional area of the pipe introduction part is Ikm' and the flow velocity of the air mass at the pipe introduction part is 10 m/s, and the wind energy generated when the pressure at the top part is the same as atmospheric pressure. The vertical height of the pipe is the difference between the atmospheric pressure and the atmospheric pressure at . The temperature of the air mass at the time of introduction is shown as a parameter.
Furthermore, the air mass contains water vapor and is cooled below the dew point. When moisture in an air mass condenses. Because the temperature of the air mass follows the IW athermal lapse rate. This is because the temperature is higher than that of a dry air mass. The work ΔW for the introduction of air mass into the unit quality indigo increases. Furthermore, in addition to the method of increasing the temperature of the air mass, there is also a method of humidifying the air mass, that is, a method of increasing the latency of the air mass. Wind energy can be generated similarly if the temperature lapse rate is greater than the wet adiabatic lapse rate. The efficiency of this heat engine is determined by the temperature at the bottom of the tube and the temperature at the top of the tube.
It depends on the vertical height of the pipe, the lapse rate r of the air temperature, and the heating temperature, but as shown in Table 1. Using slightly hot gas, which is only a few tens of degrees Celsius higher than room temperature, which was previously difficult to use, it is possible to convert it into wind energy with high efficiency. +! II.Ideal for large-scale use of solar energy. Large-scale wind power up to hundreds of millions of kW can be obtained. This wind energy can be converted into electrical energy with high efficiency. Also, if a high-humidity air mass near the AM layer is introduced into the tube.
WRf'A Condenses water vapor in the cooled air mass. If fresh water can be obtained and the pressure at the bottom of the tube is the same as atmospheric pressure, the pressure at the top of the tube will be relative to the surrounding atmospheric pressure.
In addition to the method of holding tubes using mountainous terrain or artificial horizontal objects, which create high pressure, the differential pressure created by this can also be used to hold heavy objects, such as balloons, at the top of the tube. In this case, if there is strong wind in the sky E, add a tail to the pipe. You can also use lift. Also, connect a balloon to the tube. It is also possible to use the buoyancy to hold the tube in the air. The L ascending airflow inside the tube is fully formed. The pressure at the center is compared to the pressure around the tube. It can also be a low pressure. still. Temperature lapse rate is dry P. Reduction rate ``If greater than, R
In an absolutely unstable atmosphere, it simply causes the air mass on the surface to rise. Because the temperature is higher than that of the surrounding atmosphere, the apparent thermal efficiency may exceed 100%. The same is true when the surface air mass contains a large amount of water vapor and the temperature lapse rate is greater than the humid adiabatic lapse rate, that is, in a conditionally unstable atmosphere. The pipes may be installed along slopes in mountainous areas or by artificial horizontal structures. Furthermore, it takes advantage of the buoyancy of the air mass. Alternatively, the buoyancy of a balloon or wings attached to the tube may be used to hold the tube at a high altitude. [Example] First, there is a pipe 1 that is vertical or has a gradient in the vertical direction.
At the bottom of this tube 1 is an air mass introduction port 3. The air on the ground is heated or humidified, or heated and humidified by a heat exchange means 6 using solar energy, warm seawater, waste heat, etc. as a heat source in the tube 1 having an air mass outlet 5 at the upper part of the tube 1. By doing so, the surrounding atmosphere. By introducing the air mass 2, which has become buoyant due to its low density state, through the air mass introduction port 3 installed below the tube 1, an upward airflow that moves upward within the tube 1 is generated, There is a wind generation method that is characterized by generating wind energy from this updraft. In the above, the outer shape of the above tube 1! Linear or wing.
Alternatively, a wind energy generation method and device that connects a balloon and uses the lift force exerted on the wings by the wind in the sky and the buoyancy of the balloon to control the attitude of the tube. Wind power generation methods and devices, fresh water production methods and devices are also considered. The pipe l may be installed along the slope 4. Further, the tube 1 may be reinforced by inserting a strut 8 therein. In addition. As wind power conversion means 7. If a windmill is selected, this is done to alleviate the torque that the windmill applies to pipe 1. A combination of windmills that rotate in opposite directions may be used as the conversion means 7. [Effects of the Invention] The wind energy generation method and system, the wind power generation method and device, and the freshwater production method and device according to the present invention are as follows. As a result of the above-mentioned efforts, the following effects arose. In other words. The air mass, which has been heated to have a lower density than the surrounding atmosphere, is introduced into a tube or pressure-resistant tube. ．． This wind energy can generate updrafts and generate wind energy. It is now possible to generate wind power and produce fresh water. Furthermore, the tube is made to have a lightweight structure that can withstand positive pressure, and the pipe is designed to be able to withstand positive pressure by applying a pressure of M to the surrounding atmosphere. By suppressing it. We have made it possible to create a self-floating tube with buoyancy that can reach high altitudes. Yet again. Add a balloon and wings to this tube. Added the ability to increase buoyancy.
