Your dedication is admirable, that's some heavy work. I caught lyme from a tick and didn't get to my big project this year, had to hire help just to finish my firewood. But your effort is an inspiration! It'll be interesting to see how this one compares to the smaller one, hope you're using some really slick bearings and grease for all that weight. If it turns out too heavy, you might consider a lighter rotor of metal tube framing and thick fabric/tarps/plastic sheeting for the fins. Excited to see how it turns out, this one could produce substantial usable power. Have you kept track of the costs if someone were to buy all the materials? Or the weight of the frame and especially rotor, just for curiosity's sake?
If you watch the video of the first part of this build, it will help you to have a better understanding of the plan. -link: "ua-cam.com/video/A-NUT3iuvBk/v-deo.html" Yes, weight of turbine important. -it will be mostly carried by 3 wheels attached to frame. Cost is also being considered, and availability of material; and what ever else that turns up for changes.
Interesting approach, I quite like it. I'm assuming the plan is for an equally large and low cost gear ratio as well? A cone CVT perhaps? Using mass to offset height and keep the cost low is a clever angle, but a safety stop might be a challenge ... maybe an outer ring of chicken wire that can quickly be covered with tarps? My concern is braking at the wheels could cause some twisting and rapid disassembly should the wind speed really start to run away with it. Looking forward to see how this goes - bang for the buck the concept seems very solid
You're right in line with some of my thinking! My plan for 'off and on', is to place galvanize remesh around the outside working area, with small tarps to hang, and operate like a curtain. The gear train/drive train, is going to be the three wheel barrow wheels supporting the weight of the turbine on the track at the outer edge. The gear ratio will be around 10 to 1. The weight of the turbine will supply the traction for the wheels, though I may have to clad the track with sheetmetal if it starts to tear up. There are some unknowns, but this is how you find out...
Real easy to get hurt on that scale. Please be careful. For best results respecting laws of physics, you want weight at center of pivot whereas weight on peripheral will disproportionately resist rotation. Ever consider a darwin wind pipe for simpler construction?
Extraordinary size and design. Definitely following this build!
YOU most certainly think BIG !! I like your method too. v
pretty darn impressive to have done that by yourself!
It looks awesome
Thanks!
Great work as always!
Much appreciated 👍
Awesome!
Thank you!

Cause pine wood lasts to darn long outside....
