Remember the space program? Yes, it provided all sorts of great spin-off technologies, teflon, velcro, satellites for everything, increased computing power, etc.
Now, the submarine world can add something of value. A chair that uses technology from reloading torpedoes. When you look at this chair, you'll ask, "Why?"
But, nice to see we can reuse some of the stuff that goes into our boats in commercial applications.
Does anyone know of any other developed for submarine technologies that have made their way into everyday use?
