Here is footage from the presentation I made for the Windempowerment Conference in Athens last month. Actually this is a backup that was not used at the conference as I was able to make the same presentation live (and said a whole lot of different things, I think). Anyway this backup version is too long to upload as a single video so I have split it into 3 parts: Scoraig Stories, Alternator Design, and a shorter subsection: Ferrite Magnet Windmill. This last is an intro to my new 2F design document
sorry about the poor sound quality
More about windmills in the old days on Scoraig here
Dear Hugh, i have your plans for the 2f design and would be very interested in building the 3F. wind turbine. Would it be possible to purchase a set of plans from you. I have also dabbled with the idea of a machine with 19 inch rotors, 16 50mm by 75mm ferrite magnets per rotor and a 3.6m blade but was wondering how many coil windings to use in the stator coils for a 48volt machine. Hope t0 hear from you soon.
Kind Regards,
Arthur Sheridan.

Hi Arthur,
I tried to reply by email but the address did not work. You can email me at [email protected]
I can send a draft version of the 3F plans that gives all the info you will need but it’s not a very finished document. Donation would be welcome.
3F uses 40 cm diameter disks and 16 magnets 75×50 each disk. I also have a 4F design using 50cm disks with 20 magnets each 75 x 50.
cheers
Hugh
