Turbines / cooling fans / airplane wings / windmills

WHALES have been swimming around the ocean for a long time and are able to dive hundreds of feet below the surface and stay there for hours.
.
How can they feed their massive size only with microscopic animals but still have such powerful tails ?
 .
In 2004, scientists at Duke University, West Chester University and the U.S. Naval Academy, discovered that the bumps at the front edge of a whale fin greatly increase its efficiency, reducing drag by 32% and increasing lift by 8%. Companies like Whale Power are borrowing this concept and creating wind turbine blades that greatly boost the amount of energy created per turbine, and other companies are applying the idea to cooling fans, airplane wings and propellers. This is nature’s solution to the problem of
speed and agility under water.
.
These research also helped structures to generate windmills more efficient and quieter.
