video Wind Mill (vertical axis wind turbine)
Students of Drafting and Engineering at Truckee Meadows Community College (T.M.C.C) build their own version of a vertical axis windmill. The plans were drawn by using the free student versions of AutoCAD / Inventor offered by AutoDesk to students of the school.

The goal was to make it out of the most affordable parts from any hardware store. This was made with 2 sheets of plywood, 11 2x4's, 2 PVC pipes, paint, skate bearings, bolts and screws and cost less than 200$ per unit without the generator (300$). The reason for the size was that the generator was 'high output' and could barely be turned by hand, if you choose to use a car alternator, then you should downsize this design and switch to metal flashing. I hope to have a link for files soon.

If you are in RENO, I recommend the drafting program for 3D AutoCAD. It will help you design and create whatever you like to build.

an average output over time would be a phenomenal contribution........

I agree, but since we built it for someone else, I don't have one. If you do it, let me know.

You can add some realism to this project by trying to solve the reliability issue of dirt getting into the thrust bearing. Or you can solve the maintainability problem of quickly replacing a dirty bearing that has frozen the rotor.

What sort of power output did you get?
