How to build a windmill part 2: Parts, nuts, bolts and blades (2012)

Nice, I've always imagined I would build an windmill of some sort. Having seen the hydro-rock energy storage device I could imagine an interesting combination there, pumping water to lift the rock, using the water pressure from the rock to generate hydro power.

It has also always disappointed me that turbines in California were so constrained by wind speeds, between X and Y MPH they could turn, under or over those numbers and they feather their blades and stop. I'd like to experiement with turbines that could work in any wind that didn't physically cause them to fall down.

True story: (dad and granddad owned a water well firm in NV)

I was sent out to assemble a windmill one day. All the precut/predrilled angle iron was banded. There was a wooden box with the bolts, nuts and (cast) head.

When I got to the site, I opened the box, and there was a paper with instructions printed thereon.

The instructions read:

"When properly assembled, all parts will fit."

It was a puzzle.

I'd like to have that thing on the roof of my house hooked to a powerwall, is that even possible?

A few minutes with a pair of strong magnets taught me more about the nature of exponential force than all of the books and math I've ever seen. Great care you must use. Powerful in the force are they.

Scared of losing fingers, but this is cool :-)
