What would be a good material for creating a custom vertically oriented wind turbine blades? Answered
For a school project my group an I are building a vertically oriented wind turbine similar in orientation to the one in the link(http://www.youtube.com/watch?v=rLa_NY5U1nk)
We would like to build a few different designs to test which will give us the best efficiency as we will do using it to generate maximum output voltage.
I'm wondering, what would be a good way to create these different custom pieces, especially the curved airfoil shapes we may wish to utilize in the design?
