I need to build several types of blades for a wind turbine to see which one produces the most electricity. Any ideas.? Answered

I found some good designs on here that I can use, but I need some various blade designs so I can switch out the blades and do my experiment. Trying to help daughter with science project.

there are a few options - non-scientific terms ahead: flat angled - where its just an angled cut thru a rectangular board - to make a wedge shape aerofoil shape - where the edge is rounded, and shaped like a plane wing 'scoop' shape, like half-ping-pong balls on sticks that literally catch the wind. Those are the simple 'blades'. There are some pretty fancy sauvinous/vertical axis wind turbines with combinations of these styles...
