Materials to Make a Wind Generator Propeller With

When building a wind powered generator from home, one of the things that you need to decide on is the materials to make a wind generator propeller with. The propeller is one of the most important parts of the wind generator, and the materials you use to make it would determine the efficiency of the wind power unit and the amount of electricity it can produce.

Here are some of the common materials used to make the propeller part:

Generator

Wood

Traditional windmills have propeller blades made of wood. In fact, there are still a number of wind generator designs that make use of wood for the propeller part. Here, red cedar wood is ideal for it is relatively inexpensive and strong. But it would be quite a task to carve out the propeller from a piece of 2' x 8'.

Metal

Metal is another choice of material you can use to make the propeller with. It is also lightweight and can rotate easily in the wind to produce more electricity output (depending on what metal you are using). But the cost of getting it might be a deterrent to most.

If you are using metal, you also need to take special care to protect it from the effects of weather too.

Plastic

In most wind generator designs today, plastic is the most preferred choice of material to make the blades with. I built my wind generator with PVC plastic propeller blades. PVC plastic is quite easy to find and is also relatively cheap - in fact, I found the piece of PVC pipe from a local scrap yard.

With PVC, you can make a durable, lightweight, and cheap wind generator propeller from home. This would add to the energy efficiency and more power output from your homemade wind generator, hence more money saved month after month.
