Whale

● Humpback whale flippers have bumps called TUBERCLES along their edges, which allow them to move efficiently through water. Envira-north Systems is creating industrial- size fan blades with whalelike tubercles to REDUCE DRAG. “What’s cool about it for wind turbines is that you can operate at lower wind speeds,” Benyus says. “That opens up the opportunity for wind power in zones that are no-go now.”
