The Hugh Piggot HAWT put out 500 to 600 watts when it started to furl.
The venturi turbine added anouther 250 to 300 watts. It was a little dissapointing but it did add some output out of a relativily short 35 foot tower.
it was a fun project put I scrapped it. The parts will get used for other projects.
The alternator is direct drive from an 8 inch stainless steel 3/4 inch shaft coupled by a flex coupling to the rotor. This allows the airfoils to expand and contract with temperature without effecting the air gap of the magnet rotors. The top bearing is also a unique design that allows the turbine frame to flex without loading up the bearings and shafts.

Interesting turbine but what were the results of the data? THe vid's called collecting data.

Looks Great.
Can you show us the gear part with PMA ?
Thank You.
