Converting to green energy can help you save a lot of money on fuel bills, and one of the cheapest ways to manage this is to build a wind energy pinwheel. These small turbines can be used in a garden or on a smallholding, and will provide enough power to refill a battery, or produce small amounts of energy for lighting or warming water. Once you have made one small wind energy pinwheel, you can make many more, and this is the key to providing yourself with cheap, readily available energy throughout the windy season. In order to make this little pinwheel, you will need a few household items, and a pinwheel template which can be found in many places online.
Step 1 - Make the Pinwheel
You will first have to create your own pinwheel on the card. Pinwheel templates are available online, but they are essentially a regular square shape, which you can make and print out yourself. Lay down your pinwheel template on the piece of card or stiff paper, and then draw around it with your pencil. Remove the template once you have made the drawing, and then cut out the shape using your scissors. If you wish to, you may color or decorate the pinwheel card. This is a good idea if you want to create a number of them, as the different patterns will provide an interesting spectacle as they turn in the wind.
Step 2 - Cut the Pinwheel
Once you have made your square and decorated it, you will need to cut each of the corners of the pinwheel, almost to the center, but not quite. Leave a space about a dollar in size around the middle of the square. Use your hole punch to make holes at each of the corners, so that each of your triangle 'wings' have a hole cut in the lower left quarter. Using your sharpened pencil, make a hole in the center of your pinwheel.
Step 3 - Make Your Wings
Take the triangular shapes of your pinwheel, and turn the point with a punched hole towards the back of the card, and line up the punched space with the hole at the middle of the wheel. Glue these into place, and then push a small peg, nail or card fastener through all of the holes.
Step 4 - Fit the Parts Together
Once you have your pinwheel fastened together, take the straw, and push the other end of the peg into the straw, and then secure it on the other side, either by gluing, extending the legs, or by adding a nut if you are using a screw. Don't fasten completely, as the pinwheel needs to be loose enough to move. You can now attach an energy turbine to the back of the pinwheel, and push a stake or piece of wood through the straw to support your pinwheel outside.
