Here are afew pic's of the turbine I have been working on this past spring. All of this was CNC Machined on a Doosan 2000sy 6 axis Lathe.
-
was it ever found out what this nice item of garden art actually produced in watts ?
-
I'm wondering why it has only three blades? Why not 7 or 11?
-
The money shot right there.I bet that took a while to wind out. ;)

Because the more blades you run, the slower it turns and more power is eaten up by drag. It actually has 5 blades though.
-
nice work....whats the specs on it..?
-
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
