Dan Bartmann in action at Otherpower building and testing a new design alternator for a 12 footer (3.6 metre diameter turbine). See his full description on the otherpower discussion board of this machine with 15 inch magnet rotors, and thick 2 inch diameter magnets. He squeezes a bit more copper in there, and can get 1000 watt continuous without overheating while testing on the ground. Nice work.

nice email received:
From: Mike Allen
Subject: Re: A Wind Turbine Recipe Book
Date: 12 April 2013 10:53:18 BST
To: jytteI recieved the book yesterday and when it arrived I thought ‘this isn’t worth £12’.
But how wrong I was once I’d opened the envelope and settled down to read the contents with a cup of coffee. 3 hours later the coffee was stone cold and I was still reading the book.
Loads of info to be getting on with.
I’ll email Hugh when my terbine is up and running with some pics.
Thanks a lot.
Michael.
