a) Does it really work?
Yes, we know that turbines can produce electricity, see how much is produced in the UK right now at: http://www.bwea.com/ukwed/index.asp

c) What made our design the best?
It looks to me like you have a rigid design, with good curvature on the rotor arms. It is also light. All winning features, well done!

d) What made our design win?
See answer above, and well done.
