When I pick up a Home Power Magazine, or a Backwoods Home, or a Mother Earth News. I read the letters to the editor and I think, These are my people! This is my tribe—the tribe of folks striving for independence of thought and lifestyle, who are creative in their choice of building materials, who try to make responsible choices about how their choices affect the environment they live in.
While writing this article I put a lot of thought into getting the information to the people. Well here goes :^D . A list of important things to know and remember.
- All motors are generators ie electrical motors, not engines.
- If the motor is a DC motor, it will produce AC electricity if it is used as a generator.
- Generators function better if you don’t have to create the magnetic field ie they need magnets in them to perform best.
- A moving magnetic field near or through a coil of wire creates a voltage and current that is AC, The stronger the field the higher the voltage and current, also the more turns of the coil increases the voltage.
- AC electricity can easily be converted to DC to charge Batteries with a Bridge rectifier.
Here is a excellent video on how to build a inexpensive wind turbine generator with these parts.
- recycled DC motor from treadmill or other appliance (DC motors have magnets in them already)
- 24 inch of plastic pipe schedule 80 / 8 inch pipe, you should get 6 blades out of.
- 24 inch alum. square tube
- 8×12 piece of tin for tail fin to guide into wind
- length of pipe to mount the wind turbine on
- pipe clamps
- a union for a swivel
- a bridge rectifier
- copper wire
- a 12 volt battery (or multiple batteries in a bank)
