Take your home wind turbine step by step and enjoy the energy of the wind

Having solar home energy systems (or considering having them) is something more and more common. However, it is not the same with the wind, would you like to start taking advantage of this source of energy? If so, we show you how to make a homemade wind turbine up to 12 volts, which you can install in the patio or on the terrace of your house.

Materials.

home wind turbine materials

The materials we will need for this project are:

  • A motor. You can reuse it from old electronic equipment, such as old printer, video or scanner. If you don’t have one on hand, you can buy it online.
  • PVC cutter.
  • A piece of PVC pipe between three and four inches wide and about one inch long.
  • Another piece of PVC pipe of the same diameter, but about three inches long.
  • A piece of PVC pipe 2.5 cm in diameter and 2.5 cm. long.
  • A T-piece for connecting PVC pipes approximately 2.5 cm wide.
  • Part for assembling PVC pipes.
  • Plastic (eg from the case of an old CD).
  • A flange for the support.
  • 22 AWG wire (0.6 millimeter in diameter).
  • Wire stripper.
  • Blades.

Instructions.

  1. First step: prepare all the pieces.

    Cut the PVC pipes to the correct size. Remove the ring from the pipes as this will prevent them from turning easily.

    Take the motor and wrap it in electrical tape until it clicks into the pipe connection piece. Next, cut and strip the ends of the wire making sure you have enough extra material.

    Cut off the piece of plastic you had, in this case the CD case, and be sure to clean it of any protruding pieces. Now, with the 2.5 × 2.5 tube you had, make a cut that the CD can fit into. For this you can use a PVC cutter or a saw.

  2. Second step: wiring.

    Solder the cable to the motor. In this case, the positive of the motor has been soldered and marked as negative and the negative as positive since it will be used to take energy and not to receive it. Once soldered, slide the cable through the T-piece, the 3-inch pipe, the connector, and the other pipe, the 1-inch.

    Drill a one-inch hole in the pipe and slide the cable through. Then connect all the parts making sure they are not too tight as this will prevent the impeller from spinning.

  3. Third step: wind turbine fin.

    Attach the CD case to the 2.5 × 2.5 tube by sliding it into the cutout you made earlier. Later, join this pipe with the T-piece.

  4. Step four: paste and test.

    Check that everything is assembled well and glue it. Again try not to over tighten in this phase because if the parts are too tight the generator will not spin.

  5. Step Five: Check the Results.

    If all went well, your homemade turbine should be working perfectly.

  6. Sixth step: final suggestions.

    In these images, you can see several options for the blades for your homemade wind turbine, including a solution made from a plastic bottle. Among all the options, the ones that gave the best results in light winds were the blades purchased on the market, four of which were incorporated into the wind turbine.

    As you will also see in the pictures, you can combine wind and solar power by adding a small panel to strengthen the motor and provide additional power.
