About Which gear should the wind cannon use to generate electricity
A gearbox is typically used in a wind turbine to increase rotational speed from a low-speed rotor to a higher speed electrical generator. A common ratio is about 90:1, with a rate 16.7 rpm input from the rotor to 1,500 rpm output for the generator. Some multimegawatt wind turbines have dispensed with a gearbox.

The drivetrain on a turbine with a gearbox is comprised of the rotor, main bearing, main shaft, gearbox, and generator. The drivetrain converts the low-speed, high-torque rotation of the turbine’s rotor (blades and hub assembly) into electrical energy.
Wind turbines use blades to collect the wind's kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity.
This chapter presents an overview of wind turbine generator technologies and compares their advantages and drawbacks used for wind energy utilization. Traditionally, DC machines, synchronous machines and squirrel-cage induction machines have been used for small scale power generation.
A wind turbine works by catching the energy in the wind, using it to turn the blades, and converting the energy to electricity through a generator in the part of the turbine called a nacelle. While some turbines are direct drive, most have a gear box that increases and controls generator speed.

4 FAQs about [Which gear should the wind cannon use to generate electricity]
Does a wind turbine have a gearbox?
A gearbox is typically used in a wind turbine to increase rotational speed from a low-speed rotor to a higher speed electrical generator. A common ratio is about 90:1, with a rate 16.7 rpm input from the rotor to 1,500 rpm output for the generator. Some multimegawatt wind turbines have dispensed with a gearbox.
What is a magnetically geared wind turbine drive train?
Magnetically geared wind turbine drive trains In a geared wind turbine drive train, a gearbox is used to step up the input speed of the generator. The typical cascade-type system configuration of a mechanically geared wind turbine system also applies to a magnetically geared system as shown in Fig. 12.
Are magnetic geared wind generators a viable alternative to direct drive?
In this paper, magnetic gear technologies for wind power applications have been investigated as an alternative to both direct drive and conventional geared systems. Studies have shown that magnetically geared wind generators (MGWG) can achieve competitive power densities for renewable energy applications.
Are mgwgs better than mechanically geared wind generators?
Comparing with mechanically geared wind generators, MGWGs potentially have high efficiency, better thermal behavior and higher reliability. The relatively complex mechanical structure of MGWGs implies higher manufacturing costs, but this can potentially be offset by savings in installation costs, reduced downtime, and maintenance costs.
