Farm Windmill - Converting up and down motion to circular? - Page 5

 
Just 'funning' you.  I spotted several problems with trying to put the
'works' at the top beginning with some sort of slip-ring to pick off
the generated juice.

  This kind of thinking is the result of listening to fools.

It won't work, if it did every farmer in the world would be energy
independent.

But think of this, a generator is nothing more than a device to pass a
coil through a magnetic field. So you mount all your magnets on a rod
parallel to the moving rod of the windmill which has the coils mounted
on it. The trick is to get the spacing right so that the coils pass
the magnets sequentially to give a continuous current. And you get to
pump water as well.

But you want to be quick, because, as soon as beemerwanker reads this
he will try to take out a patent.

Of course if you really want to get into generating big time you could
put a micro hydro turbine in the water pipe as well, I mean, as long
as you are moving water, it may as well do some work as well.



Reality, I first saw "your" concept more than twenty years ago. It was
such a success that there are, Oh Dear, none in use today.

A couple of obvious questions
How much power do you want to or expect to generate.
Do you have the required gearbox to increase the shaft RPM to drive an
alternator.
Do you have a suitable alternator.

Reason for asking is that windmills to generate power are specially
designed just for this purpose.
They use a specific blade arrangement (2 or 3 blades max,and a very
carfeully controlled blade pitch) with a very efficient alternator
designed to produce useful output at low RPM.
A farm type windmill for pumping water will make a poor generator.

I often hear this and think it false, the water pumpers spin slow, but
have quite a bit of torque and
spin in very little wind. I can't see there being a problem in gearing
one up. If the thing is going to
spin away, why not make some power?

The problem with gearing, as I understand it, is that there is some
power loss in the process and you have a lot more moving parts. The
more moving parts you have, the more chances for something to fail.

Water pumping wind turbines might not be the best for generating
electricity but they'll still work.
