Holy Moly GasPods Work
By Bob Evans
I have dedicated my life to making products that help people move freely and efficiently underwater. I have discovered a lot about fluid dynamics over the years.
I had been working on some new product shapes, inspired by whale tubercles, for some of my Force Fin design. "Whale tubercles" are the knobs or nodules predominant on the body of humpback whales. Similar adaptations exist on many marine animals, such as lobsters.
Somewhere around 25 or 30 years ago, I told my marine biologist friends that these bumps were similar to vortex generators, and helped accelerate water flowing past the large surface area of the whale's body. At the time, they disagreed and insisted they were related to feeding behavior. Others now participating in the trend of design by bio-mimicry, of which I was a modern day pioneer, have proven me right.
How objects respond to air flow is very similar to fluid flow. I decided to super glue some of these lift generating shapes, aerodynamic prototypes for GasPods onto the roof of our old Volvo station wagon to see what might happen.
I was doing a lot of driving back and forth between Santa Barbara and Los Angeles to help my father. As that was where my mind was during these drives, I forgot all about the GasPod prototypes super glued to the car roof.
*Over a 2 year period, I was driving an average 500 miles per week. I always returned to Santa Barbara with between a 1/4 and 1/2 tank of gas in reserve. After putting the GasPod prototypes on the car, I got home with more than 1/2 tank. That had never happened before.
I said, "Holy Moly," not exactly, but some words with a very similar exclamatory meaning, "GasPods work at saving fuel!" And, that is how The GasPod Project came to be.
