I was looking for another way to for free power. I maybe this mini wind turbine that actually works. I connect it to a charge controller that allows it to charge my 12 volt batteries. This is a smaller turbine but works on the same concept as the big turbines. I got my turbine off line and bout the pvc pipe at local hardware store. I was pretty easy to make and interested in green/free energy I would recommend making one.
Tools and Supples
4 PVC 90 connectors
3 PVC T connector
Building this 12 volt wind turbine is pretty straight forward. Depending on the size of your turbine will help determine the size you want to cut your PVC. I cut to pieces for the long bottom sides at 18 inches. Then to make it square i cut 4-8.5 inches pieces to make a square. I cut them 8.5 inches because the T connectors will take up space. Then you are going to need to cut to more pieces of PVC that are the middle PVC pieces that connect to another T connector that the turbine will go in. On one of the side PVC pieces i drilled out a hole for the wiring to go threw. Then I ran the wire threw the PVC up threw the to and then soldered the negative and positive wires to connectors.
looks cool when spinning
