OK, so I'm new to all the various locations and please don't shoot me if I posted this in the wrong place.
A bog-simple AC generator can be created by wrapping copper wire around a non-conductive tube (cardboard, thin wood, etc) and then spinning three or four magnets inside it. Given that we can create magnets (subject hot iron to a powerful electromagnetic field and Bob's your uncle), we should be able to attach magnets to the central spindle of the windmill, construct the armature of wire around it using wooden lath, and increase the power drop off the windmill without violating any known laws of thermodynamics. We'd be getting better throughput, but we're still well under 30% power transfer; wind just isn't that efficient a source..
For what it's worth, windmill-driven water pumps in New Mexico frequently use this design. The mechanical drive operates the pump, while the electricity powers lights or agitators in the trough to prevent the growth of algae or mosquitoes.
Also, I understand that this is the design used in some power turbines, where smaller generators link in series to produce electricity, rather than a single generator trying to do it all.
Spire network, is this a thing or have I wandered outside the boundaries of Medinan science?
