I'm always interested in people who can think outside the box so look forward to an explination of your winding method.

Oh meant hopes (4)for 700w but 800w would be nice;)
A perfect example of why we discourage the use of "texting" shorthand type posts. Taking the time to type that one out would have saved you the time to type the clarification, for example. Plus, a lot of these guys are old farts [I know Allan is!] who don't use those devices so don't know the "code"
Proper spelling and grammar go a long way towards clear communication.
Just a bit of advice to help make your time here more profitable mining information.

Yes I am sure you can do it as a Torus in about 4 forms, some with teeth and some without. It will be hard work and at best you may save 30% on magnets but those little tiny cubes are not going to make life very easy. Pull in Lbs is meaningless so that doesn't give us much of a clue.
Using a Torus you shouldn't be using the common 12/9 dual rotor as a guide, that is not the way to do it. There is nothing magic about the 12 0r 13" disc diameter either so I wouldn't limit yourself by that.
I think a well designed torus should work quite well, but the actual performance will be no different from simpler constructions and unless you do something with the matching of the load the efficiency will be the same.
Don't thank any of us for help, nothing posted here is going to be much help to you and you will have to start from scratch rather than try to adapt windings for a different type of machine.
Good luck and keep us posted.

Even with the torus I don't think you will be even near to handling a 10ft prop.
You can't settle a winding without deciding a speed so you have a chicken and egg situation. If you build the alternator for 10ft and miss then it will be too slow to fit smaller blades.
I am inclined to think you would probably match an 8ft machine reasonably well.
The core will cost you much more than sensible magnets but it will be interesting.
