1980’s copy of Mother Earth News had pushed the designers and developers towards making a Savonius turbine through assembling the 55 gallon PVC containers from closest flange and sheet metal screws. This was probably to flourish a design from recycled stuffs. The essence of this design is that such Vertical-axis wind turbine can resist over 70 MPH winds and that too without destruction.
Complexity level: Moderate
Time required: It depends on the expertise and experience so differs from person to person.
1. Plastic (50 to 60 gallon)
2. Compass or sharpie
3. String or straight edge
4. Poly vinyl chloride pipes
5. Closest flat surface
6. Screws of sheet metal and nuts
7. Hand tools or electric tools
9. Lazy Susan supporter
12. Wire or chain
Procedure to build vertical axis wind turbine using recycled parts:
Step 1: Bisecting outline on container: Deal cautiously and do not slash diagonally or across the thick tube-shaped opening. Use sharpie and straight edge or compass and string and draw bisecting outline on container.
Step 2: Slash the containers and unite the halves: Do not let the container move while slashing the long sides of the container. Bring a piece of wood or any device to firm the position of the container or fix the container next to the wall by a solid article that is heavy in weight. Use the hand tool to slash the container. Arrange the containers and fasten them from closest flange.
Step 3: Use poly vinyl chloride pipes: Hit the pipes through all of the containers to situate them at ninety degrees away from each other. Drill into the pipe through the closest flat surface and place the container by using the rivets of sheet metal to the surface.
Step 4: Exploit Lazy Susan support: Drill countersinking holes in the wood, if required. Combine two support assemblies and for this, use Lazy Susan bearings, and wood. Utilize closest flat surface and accumulate it to drill a hole. Fasten it from the screws of sheet metal that will get combined to poly vinyl chloride pipe.
Step 5: Turbine accumulation: Accumulate the turbine and generator to arrange the gears of small size.
Frequently Asked Questions:
What is the right process of connecting the halves?
Unite the halves: Arrange the container in a manner that the two halves of the container overlap each other with nine inch. Fix the halves together by a flat surface which is stuck to an object that will fasten it and will make it stronger. Through the container, drill four quarter inch holes by using flange spacer. Now put in four quarter inch bolts and nuts to fasten the container and finish the process of connecting all the containers.
- Instead of electric tools, prefer hand tools.
- To prevent from accident, use chain or chicken wire to make an enclosed structure around the spinning turbine.
Things to watch out:
- Cautiously surmount the hand tool while cutting the container.
- Be accountable while using gears.
