DIY Energy Wind Turbine

Finally you can rest your green conscience by building your own wind powered generator. ThisDIY wind turbine is easy to build especially since the authors show you how with step-by-step instructions. The wind turbine is unsophisticated in design but efficient as it produces about 84 Watts with 30mph winds. It won’t eliminate your entire electricity bill, but it’ll help you start your journey into the alternative energy movement.  Check out our DIY Free Energytutorials and more details below.

The author’s website at Velacreations.com guides you through the nitty-gritty of putting the contraption together.  So go ahead, give this windmill a whirl. Reduce your electric bill and your carbon footprint in one go.

The motor is the core of Chispito. Without it, forget about the rest. You are looking for a permanent magnet motor. Why permanent magnets? Because they work well as generators, which is what we want here. Also, they don't normally require high rpms to get some usable power out of them. To find out if your motor might work, look on the label and find the rpms. Then, find the working voltage. Divide rpms by voltage to get rpms per volt. For this sort of machine, you are looking for 25-35 rpms per volt. The more rpms per volt, the faster Chispito needs to turn to charge a battery, which means you will need more wind before it will start charging. So, go for low rpms per volt.
The motor should also have a hub attached. If it doesn't, you'll have to find something that works. Saw blades, pulleys, and hubs from something else might work, but remember, this thing can get up to 1500 rpms, so get that hub on there tight!
The motor should be easy to turn by hand, and it should produce a bit of voltage with a hand turn. Something in the range of 1-2 volts with a hand turn will be great. If in doubt, hook the motor to a lathe or drill press to get a good representation of what it will output at set speeds. If the machine can't get power out of it, neither will the wind.

o    Blades
These blades are designed to be cheap and easy to make. That being said, blades can be very dangerous. Our suggestion is to use the thickest material possible, and for heavens sake, paint it! PVC is vulnerable to UV damage, so paint will help with that. The green sewer pipe that is 3/8” thick makes great blades that are durable. We have had several sets that have survived falling from 20 foot towers!
Other sizes of pipe will work, but performance may change. If you use below 8 inches in diameter, it might be an idea to use 4 blades instead of 3 on your Chispito. Make the blades as wide as you can, and maybe a few inches longer.
Longer blades will help start the generator at lower wind speeds, but the output on the high end will be lower. Design for what winds you have. If you only get small breezes, then make your blades wide and long, and maybe add an extra one. If you get hurricane winds every day, keep the blades short and thin, and you'll easily produce a bunch of power with this machine.
The mount and tail should be sturdy. Weld the mount to the yaw pipe, if at all possible. Also, make sure your tail is on there good. If it vibrates, then add a bolt that goes all the way through the mount.
Tails are more effective if they are big, so don't skimp on the size. We like the metal casing of washers and dryers for our tails. Those cases will make a lot of tails, so make them as big as you can.
Balance of the mount and tail are extremely important. Without proper balance, the machine will vibrate and create stress everywhere. It will also be noisy. So, add weights, drill holes, and do whatever you can to get it as balanced as possible.
