| Whales inspire better blade designsToronto - When biologist Frank Fish spied a figurine of a humpback whale in a Boston gift shop and noticed the pointy bumps along its fins, he said, "That has to be wrong." But when the shop manager produced a photograph that showed the leading edge of the long fins was indeed serrated like the teeth on a saw, Dr. Fish was intrigued and decided to investigate. He discovered that these bumps, called tubercles, are this creature's secret weapon, allowing a whale the size of a school bus to make tight turns and capture prey with astonishing agility. Fish, a biology professor at West Chester University of Pennsylvania, is now using this technology perfected by nature to produce fans with serrated blades that use 20 percent less electricity than traditional models. This finding contradicts conventional designs that strive for the smoothest possible edges. continued here: http://www.csmonitor.com/2008/0516/p13s01-stgn.html

| Most good innovations tend to come from people without government funding. Public money tends to stifle the imagination.
I always come to my conclusions by careful, scientific observation.
But only if the results of said careful, scientific observation fully corroborate my biased opinion. If It Ain't Dutch, It Ain't Much
