Cardboard Savonius Wind Turbine

Step 5 Attach the paddles

1. Double or triple up one of the rubber bands and push it up the axis rod to within about 2 inch from the top. The purpose of this and the other rubber band is to anchor the rod to the disk via friction. The also help to keep the turbine from slipping up and down.

2. Push the axis rod down through the center of one of the disks. I suggest that you keep the side of the disk with the angles drawn facing up for easlier alignment of the paddles.

3. Push the rod through the center of the second disk with the side of the disk with the drawn angles facing down. Slid the disk up the rod to within about 8 inches of the top disk.

4. Slide the second rubber band up the rod to within an inch of the lower disk.

5. Push one of the paddles onto upper and lower disks so that the notches on the paddle dock into the angled notches on the upper and lower disks. You might want to temporarily tape the paddle into place from the top and bottom.

6. Mount the other three paddles in same way.

7. Push the rubber band on the bottom up the rod so that it sits firmly up against the lower disk.

8. Now you can tape the paddles more firmly to the lower sides of the disks (the lower sides if you don't want the tape to show. As an alternative, you could use a glue gun to glue the paddles in place. Only do this after you have finished testing the turbine in the wind and are happy with the angles of the paddles.

how can i make this power 2 LED lights with 1 motor. what kind of motor should i use

[medius]

Now what is this hooked to that generates power?

As I said in the instructable, it is not connected to anything. I was just experimenting with the placement of the blades. Something this small might be able to run something like the motor behind a computer fan.
