1. You can use the wind power of the windmill to "win the field", dry the harvested rice, and separate the rice and rice husk.
2. Use windmills to provide wind energy to provide water, heating, refrigeration, shipping, power generation, etc.
3. The basic principle of old-fashioned airplanes is the same as that of windmills. The propeller (windmill) rotates at high speed to generate strong airflow, allowing the airplane to take off.
1. Spreading plant pollen
Wind can spread plant pollen and seeds, helping plants to pollinate and reproduce. For example, the most common example is that dandelion seeds are spread by wind.
2. Wind power generation
Wind energy is a widely distributed and inexhaustible energy source. Using wind energy to generate electricity reduces the use of fossil energy and protects the environment.
3. Improving the farmland environment
Wind plays an important role in improving the farmland environment in the agricultural squadron. The flow of air forms wind, which transports and exchanges carbon dioxide, oxygen, heat, etc. in the air. Create conditions for the growth of crops.
Utilization forms of wind energy
The main form of wind energy utilization is to convert the kinetic energy of atmospheric movement into other forms of energy. Wind is horizontally moving air. The movement of air is mainly caused by the different intensity of solar radiation received by various latitudes on the earth.
In the equator and low latitudes, the sun's altitude angle is large, the sunshine duration is long, the solar radiation intensity is strong, the ground and the atmosphere receive more heat, and the temperature is higher; in high latitudes, the sun's altitude angle is small, and the sunshine is The time is short, the ground and atmosphere receive little heat, and the temperature is low. This temperature difference between high latitudes and low latitudes forms an air pressure gradient between north and south China, causing the air to move horizontally.
