Green Echo is a powerful wave in that it is all about using nature as design inspiration. In this case, a whale's fin is the thought provoker here. WhalePower has developed something truly remarkable – Tubercle Technology – which takes its name from the bumps on the leading edge of the whale’s flippers. This design is said to be 30% more efficent at moving air or water than other leading blades. The big man upstairs had reasons why he gave perks to the animals of the world, now with the help of scientists, humans can benefit from the seemingly odd designs in order to make our world a better place. Beautiful!
