Unlocking the secret of fish and dolphin propulsion.

Have you ever watched a dolphin swim 25 mph along side a boat and wondered how they do it so effortlessly? After experimenting with single fins and being disappointed by their thrust, I realized I was missing something. A dolphin's movement begins at the nose and head, then moves to the dorsal fins, and finally to the tail. This motion creates a sine wave, with more movement toward the tail. The propulsion isn't just from the tail; the whole body undulates. Fish do the same. Just observe a black marlin's head while it swims at 50 mph. A fish first cups its body to one side, then as it snaps its head to the other side, there is a temporary moment when the fish forms an S shape (rather than just a C). It is at this moment when maximum lift is generated. A single fin can not do this. There must be front and back fins working together.

I have invented a mechanical devise that mimics this motion and am looking for a partner to turn this concept into a product. Please contact me if you are interested.
