DIY wind turbine blade aerodynamics. what is the optimal size/angle/material?

I am using a old izuzu npr alternator for this turbine. I am using a belt system to increase RPMs making the automobile alternator a viable option for wind turbines with hopefully low drag. That being said - I have no clue how large I should make the blades/how thick the blades should be/what I should make said blades out of.

Why not make a half barrel wind mill? Seen one on a friends farm. Cut a 55gal barrow in half and mount each piece on a shaft facing opposite directions. Done. Should be cheap to build and they are surprisingly efficient.
