As this talk about the F&P designs has me wondering and I know I should get the one I have going b4 I get thinking like this. But these motors are designed to run at high rpm's correct? couldnt you re-wire each coil with bigger wire to handle much higer amps, and use gearing to get it to spin much faster with a low blade spin speed? I know I am probably overthinking this, but it seems that the rotor stator design seems pretty sturdy, so, you should be able to use heavier wire, less turns, get much more power. or would that require a blade size that is way to big to have enough tourqe to turn?Edited by readyakira 2008-07-18

Don't you think Free/Renewable energy should be mandatory in new buildings?

G'day readyakira,
Like everyone else I've shied away from this post as fanciful boy thinking. Still I don't like to see a post go unanswered so will be briefish.
Think of your motor theory where the power is made by passing a magnetic field past a coil.
You propose increasing the coil.
Most propose increasing the magnetic fields strength.
I'll leave you to ponder why this may be so.

Sure you could do both, but that then is a new motor and would you want to build a new motor with an old lossy iron core?

It is the price of the F&P that makes it an excellent power generator not its technical specs, and re-engineering co$t.

Good luck with your current F&P project.

was working fine... til the smoke got out.
