Here’s a direct link to the Instructables page for a thousand watt wind turbine project.
“We built a 1000 watt wind turbine to help charge the battery bank that powers our offgrid home. It’s a permanent magnet alternator, generating 3 phase ac, rectified to dc, and fed to a charge controller. The magnets spin with the wind, the coils are fixed, so no brushes or slip rings necessary.”
You might want to start your homebrew energy exploration with a less ambitious Pringles indoor vertical wind turbine made up of a couple of CDs, a paper towel holder, a Pringles can, and other household items.
