Blades stalling
niall:
Hughs latest books have some ferrite mags in the axial designs .....i think Proven downwind mills use them too
if your going to build an axial ..........it might be worth thinking about .....ish
i,m convinced i can corrode a Neodymium magnet .....by just looking at it
TurboMiles:
I would use the ferrite over the neo just for the price. Downwind design, no tail lol
niall:
not much help .....but theres a ferrite axial in the vid
the ferrites are very fairly big .....neos are small .....ferrites dont rust though
just a small amount of flux ... :(

TurboMiles:
I would like to build it using ferrite even though they aren't the strongest. They can still be an effective turbine, Chris Olson has made many using them and are making 2kw. I don't know all the details though. I would also like to build the coils that will allow 110v at 450 rpm and use a classic to charge some teslas
niall:
yes .. go at it again
stuff rarely goes right first time ...
in the interesting times we live in maybe having your own power is good ..........but i,m not sure what that means :)
