The designer of the Hercules, Terry Glenn Phipps, said this about the project: 

"While the goal was to make something that would fit in with beautiful architecture and nature, the corollary objective was to build using the highest quality sustainable materials available with the minimum amount of conversion and waste. This aerogenerator is made to last a lifetime without ever having to be recycled, down-cycled, or tossed."
