Inventors inspired by humpback whales make a more efficient wind turbine
"Dewar, Watts and Fish's invention has the potential to make an impact on worldwide energy consumption, particularly as we increasingly rely on green technology. Their work shows how nature can serve as a source of inspiration and innovation and how following this inspiration might lead to refreshing and unconventional technological advances."
"The humpback whale actively maneuvers to capture prey and the tubercles along with their long fins are important. Tubercles passively modify the flow over their wing-like flippers to give them greater lift and reduced drag."
"Right away from our initial [test] results we saw some impressive data. Once we had these results it was about going out into the real world and developing solutions."
A team led by Frank Fish, Stephen Dewar, and Philip Watts developed turbine blades featuring three-dimensional bumps inspired by humpback whale flippers. These innovations enhance aerodynamic performance and reduce noise. Their work has significant implications for global energy consumption and green technology. The unique structure of humpback whale flippers, with tubercles that modify airflow, contributes to their efficiency and maneuverability. Initial tests showed promising results, leading to further development of practical applications for their findings.
