this is the type of windmill I want to ad to my Energy farm portion....
I want to build a vertical axis windmill or two. they arent quite as efficient but they take up less space and the generator portion can be at ground level for maintenence.
this one is 100-400 Watts... Enough to power my well pump.
my Dad was an engineer for a carbon fiber manufacturer... He was hired on contract for them to design windmills for their own wind farm project. Mr Basso developed the technology to create carbon fiber Tennis Raquets then sold the process to Dow Corning. He made a boat load of money.... so He wanted to get involved with the bigger end of the spectrum. Dads experience was with Air foils and Prop blades...
Sow when the project was in full bloom and they were starting production Dad hired me as a detail drafts man. The fab shop would be ready to make a new part it was up to me to draw it up so they could do it.
I learned alot about Windmill Trials and tribulations during that time. OUrs was one of the first to lead the wind instead of trail the wind. and because of that they had a lower failure rate than other windmills. So the design sold and Mr. Basso invested and he got richer.... LOL.
Ours also had a generator housing that was servicible from inside. You had to climb up a sixty foot tube to enter the housing.... I got to design the tube...
The ones I want are Not so big... Maybe the Airfoil structure would be six feet tall.... Support structure would be about seven feet tall. Then the footings designed for Dynamic loading would probably be about four to six feet deep depending on Soil base.

So with this type of windmill how much torque can be achieved at the shaft? It don't appear that is could power much at all in comparison to fan blade length and the weight on a a three blade windmill. 100 to 400 watts is a very small output. If you are using this to generate 120 volts AC, you could expect .9 ~ 3.6 amps or 240 volts AC would be .45 ~ 1.7 amps.
I read that you mentioned you have a 400 ft deep well. By the time you factor in voltage drop for 400 ft of well pump wire. I doubt 100 ~ 400 watts would hadrly turn the pump at all and would most likely burn up the coils in the windmill generator or worse yet in the pump it's self or even worse both. Unless you were in the midst of a wind storm but even the I doubt it would work. I never seen a deep well pump that would operate off of .45 ~ 1.7 amps (240 volts) all the ones I've seen require 10 to 15 amps one each leg (240 volts) so 20 to 30 amps total.
Just trying to prevent a costly error. Replacing a well pump 400' down is not something I would want to pay for because i burnt it up trying to save a couple of bucks.
