I don't have a specific alternator in mind. I was just thinking of an easy way to make some airfoil shapes. A variation on the CAP 21 "icecream cone" airfoil came to mind as something I could make with a table saw and a router table. Here are pics of my first prototype. It has no twist and a 10 degree angle of attack.
