JoshK's high-torque, urban, wind turbine. Concept and plans!

JoshKJoshK Solar Expert Posts: 232 ✭✭
Hello everyone. Have a look at what I cooked up and let me know what you think. It is intended to operate where traditional wind turbines can not. I finally figured out the swimming action mechanics and had to draft it. I am looking for feedback. If anyone wants to build it, feel free to, but I would love pictures! I don't think it is a million dollar idea because of the belts & bearings required, but a do-it-yourself person might have fun creating the first ever! Questions and comments welcome.

PS - The belts are cogged belts to prevent slippage.

    I think you should build the proof of concept prototype.

    Good point, but I don't have the time or really need a wind turbine. I am hoping someone gets interested enough over it to build themselves one.

    Interesting ideas, but a ton of moving, interacting parts, and what happens during a freezing rain storm when parts start seizing up could turn out to be very entertaining.
    Would be amazing to see one operating, regardless of efficiency or lace thereof.
    Thanks for sharing.

    Do you think it might be more efficient if it was a vertical axis turbine? It would lose one of the belts and be easier to stabilize I would think.

    Thanks for the feedback guys.
    [USER="6662"]waynefromnscanada[/USER], No doubt it has a ton of moving and interacting parts. Mechanical efficiency is lost to each bearing and belt. I think though if everything is light enough loss stays to a minimum. It also gains by having a very large power stroke, 50% of the rotation. And basically no resistance on the return flight.

    [USER="379"]westbranch[/USER], Yea it would work vertically, and you could even bolt two together. But in that configuration you are better off with a industry standard design. This design was meant to take advantage of the wind acceleration that happens across a roof peak.

    Ah ha, you want to take advantage of the anabatic winds created upon heating.. should have mentioned that at the start... problem is they are quite irregular unless you have the optimal roof orientation and the bigger, and steeper, the roof is the better, and short lived over a day.

    Like the idea though.

    I had to Google anabatic, but no, that doesn't seem strong enough alone. It still needs a good breeze, but by using the roof as a funnel and accelerator it should generate the equivalent of a larger turbine. And with one mounted North/South and one mounted East/West you would catch every wind angle. And a roof-line is perfect support system to stack more on the end and build a long, powerful system with only one generator per stack. With traditional turbines on a roof you need dozens of systems. With this you just add turbine length.

    Thanks for the peer reviews :) It was a good bounce the idea off a few other people. If anyone else has comments let me know too. I will check back now and then.
