## Can a fan be used as a wind turbine?

After some painstaking work, he was able to turn a ceiling fan into a wind turbine (of sorts). While it’s true that some generators and motors can be used interchangeably by reversing the flow of electricity (motors can be used as generators and vice-versa) this isn’t true of ceiling fans.

### How long is a fan blade on a wind turbine?

The blades may range from as small as 4 feet to as long as 50 feet and be mounted on a metal lattice tower up to 165 feet (50 meters) tall. When one of the blades is sticking straight up, these turbines can average 120-200 feet in height.

#### What is the difference between fan and wind turbine?

The differences between wind turbine and ceiling fan blades arise from the contrasting design criteria: the wind turbine is intended to capture high-velocity wind to generate electricity efficiently; the ceiling fan needs to move air at low velocity with inexpensive components.

Can I use a fan motor as a generator?

The fan is a bi-directional machine, so it can transform wind energy in mechanical energy without any change. In order to obtain electrical energy, it shall be necessary to make changes in the motor to obtain a generator. The design of these motors is very simple.

Can a fan generate electricity?

One of the method for generation of electricity is through the ceiling fan blades. Ceiling fan convert electrical energy into mechanical energy.In order to achieve the motive we have to convert this mechanical energy into electrical energy. This can be achieved with the help of Faraday Law of Electromagnetic Induction.

## How much do windmill blades cost?

Structural repair of a single wind blade can cost up to \$30 000 and a new blade costs, on average, about \$200 000.

### Why 3 blades are used in wind turbine?

With three blades, the angular momentum stays constant because when one blade is up, the other two are pointing at an angle. So the turbine can rotate into the wind smoothly.
