One idea I heard was to make windmills with the rotor stator on the rim rather
than have the generator at the centre.
(As explained to me) the trade off is as follows:
the bigger the windmill, the greater the structureal efficiency (more power
per structure, the lower the required wind speed t
Not to mention sounding very complicated and expensive.

Those are DC motors, AFAIK

Sorry, I wasn't sure if it's what you wanted. (LOL)
There was a generator someone made a few years back. I think it was
developed by some guy named "Roesel"() ... or something like that.

AFAIK, the use of an "exciting" circuit is restricted to DC generators. This
is
where there is a separate field winding, e.g. shunt, compound or

y one is making progress on this route to selfsufficiency I woulod like

Don't temp us, Curtis - tell us what a rewritable rotor does :)

Actually, there WAS an AC generator which generated a constant 60Hz output
in spite of varying RPM input. It did this with a rewritable rotor.

I am based in Ottawa, Ontario. We are at the edge of the main urban area
(inside
Greenbelt), and our power was out about 12 hours. After that, we provided
support
to
in order to maintain 60 hz at multiple rpm's, you need to generate dc, and
use an inverter to get ac. not many types of ac motors can be used for ac
generators. asynchronous motors can be IIRC. dc permanent magnet motors are
interchangeable.

My understanding is that the some of the windings have to be "excited"
before the other winding will incite a current. However, this is where
my confusion comes in. I am interested to know how one wires up a motor
to act like a generator. I'll do some "googling"

Martin,
my understanding is that any AC motor will generate if turned mechanically and
the
electrical circuit is made. However, I believe the frequency (e.g. 60 Hz) is
very
dependent on maintaining the rpm of the motor (now alternator) at the correct
speed.
