Power Rubber Band
By James F Humphries
Simpler submarine designs had shown me that a strand of rubber bands about 24 inches long was needed to drive a model submarine across a swimming pool some 35 feet long. The boats would dive five feet deep after launch, cross the pool at that depth, then slowly begin to surface as the rubber band wound down and the slight positive buoyancy overcame the downward force of the diving planes. Just as the boat coasted
Jules Verne himself carefully described the geometry of his remarkable submarine in the pages of his book, Twenty Thousand Leagues Under the Sea.\Over a century ago, Verne wrote an incredible fictional account of an electric powered submarine, the Nautilus, that could operate anywhere in the oceans of the world without need for a port.
It was to be made of pine, with 3/4 inch planks glued together with waterproof resorcinol, forming a turning block for lathe work. Since wood floats, and lead is expensive, I decided to build the boat with a hollow interior. To do so, I made cutouts in each of the interior boards that made up the hull. This was done with a jigsaw before gluing the boards together. The interior cutouts had to be designed to permit trapped air to escape immediately when the submarine was immersed in water. So I shaped the interior profile to direct the trapped air to vents to the exterior surface of the boat. The idea worked perfectly so that there was no need to invert the submarine under water to let the trapped air escape.
