Although to be honest, you'll probably end up with a 300 Watt turbine before the 1000 watt one. I plan on building one the easy way first with the PM motor I was describing, and after starting to work on making my own alternator. That 300 Watts extra will make a big difference considering you only have 30 watts of solar panels !! (so 10 times more power!) :) That’s the plan !!!

Hmmmmmmmmmmmmmm? So my question is, can you build US a 1000 watt turbine from scratch for a few hundred dollars?

Your basically looking for a PM motor that can supply the required voltage at the lowest possible RPM. … and yes they do need to be stepped in a certain way.

I should have mentioned that in my article, but it'll be part of a future one. I'm still trying to figure out common ways to get a permanent magnet motor. I too have been eyeing that electric scooter I bought myself and wondering if the motor would work. I know 2 ways of getting these permanent magnet motors. Ebay is easiest. They flat out say they're permanent magnet motors and give the rated voltage. From what i've read and been told, AMETEK motors are the best for this. The other option, is OLD TAPE DRIVE motors. Not a floppy disk, the good'ol fashion Tape backup drives. Those motors are apparently some of the better ones to use. Treadmill motors are also known to be good for this. Other than that, i'm still looking. :) I have started asking all IT people I know to keep old tape drives aside for me, as well as old hard drives so that I can salvage the magnets. (The harddrives I have a feeling i'm gonna be gettings hundreds of them!) Wow that’s a great question Simon. I should have mentioned that in my article, but it’ll be part of a future one.

It is very informative and I learned how wind turbines work inside which I didn't know before. I remember from my physics lessons at school (just about) that you could generate power from a motor. What kind of motors are PM motors? Could I rob the motor from inside one of my kids motorized scooters and hook that up to a propellor? Or do they need to be stepped in a certain way.
