This is my first instuctable, so bear with me. This instructable will show you how to build a horizontal double helix wind turbine.This generates 100 percent green electricity. This is my own design. I've tested this design and found that it works well. This design similar to this is a vertical double helix wind turbine. This wind turbine is easy to build and anyone can do it. So lets begin by going to the first step.
Step 1: Things you will need.
1. A long pipe with an interior diameter no smaller in interior diameter than 3 inches (the bigger the interior diameter of the pipe, the better)
2. 8 bolts or screws that can reach the radius of your pipe (these will be used to hold your ball bearings in place (see item 6))
3. A rod 1foot longer than your pipe
4. Fasteners to hold the forms of the wind turbine blade in place
5. Three Forms(These are made by taking the interior diameter of the pipe (in inches)-subtracting 1/2 inch to get the length of the form, adding 1/2 inch to the diameter of the rod to get the width,and by cutting the diamond shape out of 1/4 inch to 1/2 inch thick wood).
6. 2 ball bearings, 1for each end of the pipe. (The diameter of the inner ring of the ball bearings should be the same or slightly larger than the exterior diameter of the rod).
7. 2 small pieces of pipe that fit snugly around the ball bearings.
8.Some 1 millimeter thick foam
9. Something to mount your wind turbine mount to (I used a tripod made for mounting large satellite dishes on).
10. Something to mount you wind turbine on (I used PVC pipe, zip ties, and rubber strips to mount my wind turbine.
11. A DC motor or alternator to generate electricity with. ( I used an RC car motor)
12. Something to connect your rod to your generator (I used a wooden dowel with a hole drilled through the center).
13. Some wood to make the tail fin for the wind turbine and the three forms.
14. PVC pipe to attach your tail fin to your wind turbine pipe.
15. Duct Tape (to hold certain things together)
(Its the best stuff in the world):-)
16. Something to attach your generator to the wind turbine tube with ( I used wood and zip ties).
Everything mentioned here can be bought at Home Depot except for the generator/ DC motor/ alternator, the tripod, and maybe the foam.
Tools You Will Need
1. A Hack Saw
2. A drill
3. A drill bit the same size as the bolts or screws used to hold your ball bearings in place
4. A drill bit the same size as your rod.
5. Utility knife for cutting the foam.
6. Measuring tape or ruler.
7. Wrench(s) if you use nuts as fasteners.
8. Stapler/ Staple Gun for stapling the foam to the wood forms.
8. Table Saw (optional--- it just makes life easier).
