Nando, I have some great news for you:
http://www.martinslade.freeserve.co.uk/
is the site that contains the PDF, at the bottom of the page there is a picture
that links to the same stuff that is in 'your' files...
If it was available on the web, you could just as well have linked to it !
Would have saved us all a lot of trouble And you would have never lost your friends email address, because, conveniently he has a link to it on his page.
Also there is a picture there of the 'prototype 11 KW machine', but this then
shows a picture of a machine that is nowhere close to 11 kW, but it does seem to sit on the tower that is in the drawings, so there probably is some connection:

The funny thing is that the tower in the picture is the tower in the PDF, but the hub in the picture (and the size machine quoted) do not match at all.
I can't help but notice that the machine that is sitting on the tower
there if the tower is 9m tall (and it is according to the description)
is only 6 m or about 18' in diameter.
I also can't help but notice that a 10 (or 11 but who is counting) KW machine is roughly 9 m in diameter, and at that size the blades would have some trouble turning because they'd hit the guy wires... Let's hope they added a piece !
if you click the image on the page linked above you land in the pdf.
Which incidentally is pretty useless for comparisons purposes because it expresses the power generated as a function of the rotational speed of the generator shaft, but not as a function of the windspeed...
Do note that the plans mention lots of hydraulics, and that this is NOT a torque hub, but a hydraulically actuated variable pitch machine. So, why do you claim it is meant to be a torque hub ? The two have very little to do with each other.
To help you in your search for your long lost 'friend' I hereby present you with his email address: simon@martinslade.freeserve.co.uk, it was recovered from the CPU you lost at great expense by the CIA using 'carnivore' and express mailed to my door via astral projection. Good to have friends in high places isn't it ?
If that mill ever flew than I'm challenging you to back it up with a picture, I'm sure Simon won't mind you posting one, since you already posted his PDF.
For now all I see is a botched attempt at making a VP hub on the floor of somebody's garage and a cheap chinese knockoff of the 1 KW bergey sitting on a tower that will not support a 10 KW machine because of simple geometry. Please prove me wrong, it would make my day. To see that machine in person would make my day even more but I think that as long as the blades are going to be attached the way the photos show that I'll decline for now.
Also, I would like to remind you that passing yourself off as an engineer when you are not (and we are talking licensed engineers here, or is a design engineer somehow exempt) is very unwise.
best regards,
Jacques
