wind energy? our theme for the science fair is energy and i am doing wind energy, i plan on comparing the blades of the windmill to measure the best amount of wind energy. My question so far is Using Styrofoam, Balsa wood and cardboard as a blade design while creating the windmill itself which one of these materials as a blade design for the fan of the windmill produce the most energy when hit with wind? i was thinking this was good but my teacher told me it needs to be more with why and how. so i am kind of stuck and not sure my idea was to see if i could find out if one of those materials was proven best and i can try to prove it and explain why. but i am not sure how can anyone help?
or what would be the best material and why if anyone knows
