Plans For PVC Pipe Windmills

Would you like your own PVC pipe windmill ?

PVC pipe is inexpensive, fast to build with, and can be used to make great wind generators. With a few tips and tricks, you can achieve great electrical output from readily available materials.

These PVC windmills are easy to make and if your thrifty you can make one for under $50.

These small, easy to make PVC pipe windmills call for different designs for different average wind speeds. One Piece of pipe can make the motor housing and the blades.

You can increase your electrical output by tapering the ends and creating an air foil by sanding the edges of the PVC blades. ( I've included a picture below )

The best plans for PVC Pipe Windmills.

The only setback I've had is that I've broken a few blades. The PVC windmill blades tend to get brittle and break at the hub. The blades are so cheap and quick to make, that it's not that big of a deal. Other than that they work great.
I've also shown how to prevent the blades from breaking at the hub. Just keep reading.

PVC Windmill Blade Design 

This is what I was talking about when describing the blades. The angle is increased as you get further towards the tip of the blade. The tips are moving the fastest and you don't want drag on the ends. This just increases their efficiency.

The blades taper towards the tip, this reduces weight and drag. The air foil is to produce lift, like an airplane wing. The result is more spin, and with windmills that's a good thing.

Two PVC Windmill Blades - One Piece Of Pipe 

Because they taper you can align them to reduce waste. One piece of pipe can make multiple blades. Depending on your electrical demands, you'll determine the size of pipe and the length of the blade.

Cutting the PVC to fashion the blades is super simple.

If Your Windmill Blades Keep Breaking 

You can make a hub that reinforces your blades. The blades are most prone to break close to the hub. This is where the most shear force is. If you strengthen your blades in this fashion, they will be very hard to break.

This also increases weight and adds drag, so unless your PVC windmill is in a hard to reach location, I wouldn't do this. However if it's difficult to reach, or on a vacation home, then you might want to consider this approach. You can always test and see what your electrical loss is.
