Wind energy could let the wind turn to electric energy.It is a kind of renewable energy and play an important role around world.”The total wind energy around world are about 2.74*10^9MV,and the available wind energy is about 2*10^7MV.The wind energy is 10times bigger than water energy.”(www.baidu.com wind energy)Wind energy is harmless ,and we can use it conveniently .In some water shortage places,they could use wind energy . “Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity.“( https://www.energy.gov/eere/wind/how-do-wind-turbines-work)
Wind power generation is about use the wind power to let the vanes rotate to create the electricity .Because the power is unstable ,so it always output 13~25v changed electricity.Simply,the wind energy just uses vanes to turn Horizontal air potential to rotate energy ,then connect it with the alternator.Generators is the mechanical equipment which can change one energy to other energy. It can change mechanical energy into electrical energy. It be made of stater, rotor and bearing.
Generators are divided into: direct-current generator and alternating-current generator. We will use alternating-current generator in this experiment. This kind of generator was use by electromagnetic induction principle to work.And Electromagnetic induction phenomenon refers to the change in the magnetic flux of the conductor, will produce electromotive force. The electromotive force or induced electromotive force, if the conductor is closed into a loop, the electromotive force will drive the flow of electrons, the formation of induced current. It’s the working principle for it.
Use a pair of oppositely placed poles. When the pole is fixed, you need a coil. You can bend the copper wire into an approximately rectangular shape with a rectangular area to ensure that the rectangle can be rotated in the space between the poles. The rectangle is not sealed, and both ends of the wire are respectively taken out, and are arranged on a rotating shaft. Then it can make electric. It’s the easily way to make generator. And we will use fan and generator together to make a invention. Generator use electromagnetic induction principle change mechanical energy to electric energy. Use wireways connect fan and generator. When generator working, the fan can rotate. We also will use wheel to make it can move on the desk and floor.And we decided to made the Fan car looks like a shoes by PVD board and Use KD board to make the vanes .It could decreases the weight.And buy some wireway to connect every thing together.If we finish use it , the boards will be thrown into the trash bin .We think this invention will very interesting and it maybe can move 10 meter to 20 meter if they wind was heavily. We choose to do it because we think use 2 different things are very creative. We want to do better than others.
