NASA’s Robot Submarine Generates It’s Own Energy

The Sounding Oceanographic Lagrangrian Observer Thermal Recharging (SOLO-TREC) is more than just a mouth full to say, it is NASA’s newest autonomous submarine robot. What looks to be a buoy, is actually a 183 pound submarine that is able to generate its own energy. According to Engadget, when the machine dives, “cooler water temperature causes a liquid wax-like substance inside to solidify, squeezing out oil that drives a hydraulic generator. When it surfaces, the wax softens once again, ready for another round”.

Every time it goes through that cycle, it produces 1.7 watts per hour, which is enough to power the buoy and other instruments used. Since the power of this robot is basically infinite, long term goals can easily be accomplished with it. Things like making a map of the sea world, but since the US Navy has a say in this project, it might just be used as an autonomous torpedo launcher.
