It seems streamlining as human engineers have understood it thus far, has a few shortcomings.
“Dolphins and whales have evolved over millions of years to maximize efficiency of movement through water. The human species has been trying to perfect streamlined designs for barely a century. Biologists and engineers, applying biomimicry, studied the flippers, fins and tails of whales and dolphins, and have discovered some features of their structure that contradict long-held engineering theories.
The shape of whale flippers with one bumpy edge has inspired the creation of a completely novel design for wind turbine blades. This design has been shown to be more efficient and also quieter, but defies traditional engineering theories.
Dr Frank Fish of West Chester University says that the shape of whale flippers has inspired the creation of a completely novel design for wind turbine blades.”
Well, duh. If you take the natural philosopher’s approach (Newton called himself a natural philosopher), you’ll learn from nature versus your own puny self.
NOTE: A natural philosopher looks only at God-givens, and makes all deductions from that.
