This is a scalable remix of Vertical Windmill Mk 2 by Miiiike.
Here at Geek Media HQ our specific vicinity to vortex-producing nearby traffic and occasionally windy weather and the recently absurd comments by ignorant politicians have inspired us to build a similar such an ancient system of capturing these effects into a usable form, and as we should know by now, having observed and gained wisdom through the teachings of everyone from Aristarchus to Galileo up to today's awareness of the weather patterns here on Oblate Spheroidal Earth as well as in the Heliosphere that everything has value and "Power", even the invisible.
This and these similarly designed systems can be scaled up to suit needs, and of course the wider your struts will be the greater the torque applied!

Thank you Miiiike for the Original Design, great work!!!

Digitmakers.ca 1.75 Carbon Fiber, Glow in the dark, Transparent
Glow in the dark GREEN and Transparent
All parts ought to be printed with 100% Solid Infill except the Spindle Mounts which i opted to print with 5 perimeters, 0 solid top layers, and 14 solid bottom layers.
Sprockets were designed utilizing "Sprocket Generator OpenSCAD" by Talon_1
-Spindle mounts reduced by 3% (tighter fittings)
-Aerofoils were cut at 79mm in height (right above the strut mount), stretched to 190% along the Z axis, and then trimmed to 140mm.
-Aerofoils without the threaded rod mountings also in .stl
-6, 9, and 31 Toothed Sprocket(s).stl files should be Solid Printable in Carbon Fiber as I opted to, in order to isolate the spindle shaft from any electrical component such as the chain and generator from lightning or even reverse voltage leak. I opted to add galvanized 2" washers and nuts to the assembly
-Joiners.stl should be printed with at least 5 Perimeters at 30% overlap at the least, or 100% Solid ( made em for when your electricity cuts off mid-print as mine did - or if youd like to cap the Helix at the opposite end :)
Best if you drill and thread the strut mounts and wings with the appropriate sized drill bit and thread.
This design should allow for slightly greater torque due to it's reduced inner arc going up the helix, so you can then make this much wider in diameter, resulting in greater torque on the central axis/spindle. Recommend using a strut width of <500mm for the 3/8" or 10mm threaded rod struts due to load limitations on these materials.
Overview and Background
The Ancient History of the Helical "Darrieus" design
Lesson Plan and Activity
- 1/4" or 6-7mm Threaded Rod(s) for the central axis spindle
- 6pcs(or more) 3/8" or 10mm Threaded Rods for the struts
- High Performance Exterior Grade Adhesive with great Working Temps and adhesion to PLA and Plastics (or whatever you print it out of)
- 2pcs(or more) "L" Stainless Steel/Galvanized Mounting Brackets
- 8pcs(or more) Skateboard Ball Bearings
- 1(or more) sprocket(s) possibly from a bicycle, ideally non-conductive material or the Sprocket .stl files included
- 1 bicycle chain 1/2 x 1/8"
- 1(or more) DC Generator Motor
- 1 large diameter flywheel
- 1 DC-AC inverter
All hardware should be of highly rigid and corrosion and oxidation-resistant metals such as Galvanized or Stainless Steel.
All adhesives and bonding agents used should be exterior grade, and water/corrosion resistant.
