Oh! Your idea is a little outdated. When primary battery technology was not yet available, a large number of toys, clocks, etc. were used. were powered by mechanical springs. But now there are all kinds of batteries in front of us, and their volume ratio, weight ratio, capacity ratio, price ratio, etc. are different. All aspects of performance are far superior to mechanical power. Therefore, unless you want to experiment or experiment with the following mechanism, in terms of real practicality, it is better to use batteries.
What are the types of wind turbines?
Wind turbines are spiral and airplane propellers can also produce electricity. The amount of electricity generated varies. One is the aileron discharge and the other. absorption. Currently all installed twist blades are high efficiency twist blades. They are mainly imported or joint ventures. The one whohe who can design a good twisted blade will win glory.
Depending on whether the propeller is variable: fixed propeller: fixed propeller, passive yaw; variable pitch: variable propeller, active yaw classified by blade: two-blade, three-blade, multi-blade; type: permanent magnet direct drive wind turbine, dual power asynchronous wind turbine; according to the direction of the axis: horizontal axis, vertical axis according to power: micro, small, medium, large and by region: offshore type, land type.
