There are two types of wind in front of the car:
One is the wind generated by its own kinetic energy (relative wind). Where does this energy come from? It transforms itself into electricity. Do you want to convert it back into electricity? Isn't it a waste of energy to move around like this?
The second is natural wind from outside, which can be divided into three types: 1. Wind from behind 2. Wind from side 3. Wind from front;
1 can be used; 2 can also be used; 3 can be used, but the available power is estimated to be not very high. Think about how much power such a large wind turbine on the front of the car can generate?
The most important thing is that the first wind is the main wind of the vehicle. The second wind can be almost ignored and serves no purpose.
So, in order not to mess around and waste energy, in reality no one will install a wind turbine on thecar.
The wind-solar hybrid street light is a lighting device that combines solar and wind energy. The wind turbine is mainly responsible for collecting and converting wind energy into electrical energy. The direction of rotation of the wind turbine is determined by the wind direction and the designed mechanical structure.
Generally speaking, the direction of rotation of the wind turbine is opposite the direction of the wind. When the wind blows on the blades of a wind turbine, the force of the wind causes the blades to spin. According to Newton's third law, the reaction force of the wind on the blades causes the entire wind turbine to rotate. The direction of rotation of the wind turbine is therefore opposite to the direction of the wind.
In addition, the direction of rotation of the wind turbine is also affected by the designed mechanical structure. Generally speaking, the rotor of a wind turbine is connected to the generator via a transmission device. The transmission device can determine the direction of rotationon depending on design needs. For example, if the transmission is geared, the wind turbine can rotate in the same direction as the wind or in the opposite direction, depending on the design of the gears.
Generally, the rotation direction of the wind turbine is opposite to the wind direction, but the specific rotation direction is also affected by the designed mechanical structure. The wind turbine of the wind-solar hybrid street light will determine the direction of rotation according to design needs to maximize the collection and conversion of wind energy into electrical energy and provide sustainable energy for lighting the street lights.
