Driving Like A Whale

Deep-sea diver and inventor Bob Evans modeled his GasPods – attached to the roof of a car to improve mileage – on the "the tiny raised bumps that speckled the heads of whales" and lobsters: 

The pods—spaced four inches apart and located 10 inches from the lip of the roof— reduced aerodynamic drag by 5 percent when a two-door VW Golf was driven at 65 miles per hour. … Speaking personally, he said, “Driving at 60 miles an hour, we went from 19 to 20 miles a gallon to 24.5.” Evans calculated that translated to a savings of $6.19 per tank.
