    If you can turn a wrench and operate an electric drill, you can build this simple generator in two days: one day of chasing down parts and one day assembling the components.

    You need 4 basic ingredients:

    1. a GM pickup truck alternator ($40 new)
    2. a GM fan-clutch assembly ($35 used)
    3. the bracket for mounting the generator on a tower or pole ($25 galvanized pipe and fittings version)
    4. a tower or pole ($20 for 15 feet of 2″ tubing, used).
    If your alternator is not GM make sure it has a built-in voltage regulator. You’ll also need some electric cable or wires to hook it up to your storage battery.

    A tail fan to spin the generator around lining it up with the wind’s direction must be attached to the 12″ nipple at the back of the bracket. Cut a fan out of old tin siding or roofing with tin snips or a cutting torch. A right angle triangle shape works best. Drill three holes in the nipple. Use self-tapping screws (steel roofing screws work good) to affix the tail to the nipple.

    Tower/Pole – Use an old Television antenna tower 20′ tall with a 2-1/2″ diameter pipe top piece. You’ll also need a Stop at the top of the tower which lines up with the Stop on your bracket assembly. This can be welded or bolted onto the tower. The Stops will only allow the generator to turn 360° clockwise and counterclockwise so your cable doesn’t get twisted around and around the pole/tower.

    A joint of 2-3/8″ oil field tubing anywhere from 10′ to 20′ in length (height) attached to a building or bolted to your truck bumper makes a good tower. Make sure it is secure and you may need to use guy wires.

    Fan Clutch to Alternator Attachment:

    The fan clutch hub can be welded directly to the alternator hub, just make certain the fan is perfectly straight in line with the alternator shaft. Make sure the alternator’s built-in wire plug ins are located on what will be the bottom of the generator.

    Once you have all the generator components fastened together, mount it on your pole or tower. Insert the pipe on the generator inside the larger pole pipe (or the top of your tower). Use two steel washers together to create a bearing between the generator and tower for a smooth surface for the generator to pivot 360 degrees. Attach the positive and negative wires to the alternator and secure with zip ties, baling wire and/or duct tape on the bracket and along the tower.

    Again, this is a Project in Progress – more to work out before this becomes efficient.

    Here is a video I found that shows this wind generator in action…

    NewWind has created a device called The Wind Tree which promises to harness wind power while having a minimal impact on the local environment. The Wind Tree is small, aesthetically pleasing, silent, and requires very low wind speeds to generate energy. To make the device even more fitting for populated areas, they have been designed to look like trees. [More]
