This is a resistance wind turbine that relies on the difference between the wind surface resistance and the lee surface resistance to obtain power. The greater the difference, the higher the efficiency (aerodynamic lines and continuous shapes avoid loss of air disturbance). energy.) The system has high rigidity and rotates The shaft is thin, the friction resistance (the friction circle is small), its linear speed is always lower than the wind speed, the transmission inertia is small and the speed stability is not good, which can be improved by a flywheel-like mechanical system. Effectiveness is related to the resistance area and the smoothness of the surface.
You must first own a wind turbine to receive wind energy. Then make a device like a bicycle chain drive to transmit the wind force received by the moldin wind to the generator, then install the generator. In this way, a small and simple generator is ready.
But it doesn't matter when it's windy. What if there’s no wind? Haha, the equipment to store electricity is quite expensive.
Added answer
I think it may not be easy for you to do it yourself. First of all, the design of the fan blades should always remain oriented towards the wind direction, and it should be reinforced. Additionally, the rotation of the fan blades drives the generator, so you must at least have a speed-increasing device in order to get sufficient power. Recently you need to configure a battery.
