OK , two things. One: Try the twisted helix design instead of the straight blade.
Two: Ametek motors are not known for good output. They simply need too high of RPM.
The generator I use needs only 120 RPM to reach 12v. Makes a big difference.
Keep in mind VAWT generators turn slower than airplane type blades. The good news is that VAWT are more efficient than HAWT type.  In other words they turn more often.
Any way, hope this helps.

Uh;


 The good news is that VAWT are more efficient than HAWT type.

Pretty bold statement. Got any figures or is it just regurgitated from some VAWT cult web site?

Bold statements require extraordinary proof.

I see you have been pushing VAWTs here off and on since 2005. Lets see yours. Oh, I guess if you had one that worked you would have bragged it up by now so I can only assume its just more talk.

If I am wrong, show us the proof, please or don't make questionable statements like:

 The good news is that VAWT are more efficient than HAWT type.

without some proof. Simple to prove, I would think ,if true.

Cheers.

I meant to type "extraordinary claims require extraordinary proof" not "Bold statements require extraordinary proof"

Just to be accurate.
