Helix spiral wind turbine

Our new design project focuses on research...1. Wind energy 2. Solar energy and 3. Reclaimed water. I spent a few hours online researching wind turbines and i found a video of the Helix spiral wind turbine... it has a rather odd shape but according to specialists this turbine is a lot more quieter and produces more energy. http://www.youtube.com/watch?v=9_xrlMV9EKM
