The Tech Behind James Cameron's Trench-Bound Submarine

MrSeb writes "Yesterday, James Cameron completed a five-mile-deep test dive in the Pacific Ocean, in preparation for a seven-mile (36,000ft, 11,000m) dive to Challenger Deep, in the Mariana Trench; the deepest place in the world. We don't know when the actual dive will occur, but it will probably be soon. At 36,000ft, the pressure exerted on the hull is 16,000 psi; over 1000 atmospheres, and equivalent to eight tons pushing down on every square inch of your body. Understandably, building a submersible (and equipment, such as cameras, motors, and batteries) that can withstand that kind of pressure, and then safely return to the surface, is difficult. This article digs into the technology required to get Cameron safely to the bottom of the ocean, film some 3D, IMAX footage, and then return to the surface."

Am I the only one that read the title and thought to themselves, "Not him again." This guy isn't as much about real science as he is about using science to grab headlines and then not sticking around to follow through. Remember how he was going to single-handedly fix the Horizon oil disaster off the coast of Louisiana? Never happened. Actually, not a single thing this guy has made headlines for has actually panned out.
