I'm wondering why it has only three blades? Why not 7 or 11?

Because the more blades you run, the slower it turns and more power is eaten up by drag.  It actually has 5 blades though.

Judging by the GM style alternator core I would say dismal performance until winds hit 30mph.

especially with 5 blades, nice work though. it may need the 5 blades to break cog and startup with that neo rotor, also going to have quite a bit of core loss with that gm lamination and the neos.

this machine appeared for sale on ebay a while back - the seller was very quick responding to me until I asked about the output, all I shown was the usual open circuit volts/RPM meaningless graph

more surface area is needed to get it spinning, but it's that same surface area that will stop it reaching a high enough RPM to produce any really useful output - alt based turbines need to be screaming around

yard art, very nice yard art
