After puzzling over why there was problem with small ,when small has always
been
a problem with wind mills in general.Worked on a device to do the same thing
as this microwindmill.
Got one ...you shrunk down the idea for the flying windmill.Go to your RC
aircraft junk bin and locate
your old tractor autogyro and modify for windmill service.The thing is
airborne in a 15mph gust and fly it like
a kite out to constant wind level.It is far enorgh up you don't hear any
blade flap and got enorgh current to run
the wall clock.Now to get it totally right. You need to hook it up to the
computer for autopilot function so you can walk away.
The plans are offered by R/C model magazine as the Whistler...less
modifications of course, for windmill.

To the best of my knowledge, small wind turbines (less than 10kW) don't
use gears. Claiming that they don't make small wind turbines because
the gears mess things up is like saying they don't make small cars
because there isn't enough room for the coal.
There are plenty of plans for do-it-yourself wind turbines under 50W
and some of them you can download off the net for free. They seem to
work reasonably well. Some designs have even made their way to powering
street lights and road signs.
