Did anyone else here see the article last summer about the engineer in Woods Hole who built a research submarine designed to circle the world (perhaps twice) with no fuel? It uses a thermal engine producing drive from the thermal variance in the ocean water to propel it forward and generate small amounts of electrical energy. It uses the electicity and a small GPS to fix it's location while sounding, and to make course corrections. DR piloting is used while diving. Now imagine this scaled up into a semi-autonomous ballistic missile sub. Scary, huh? -- "Where am I, and what am I doing in this handbasket?"
