The tech behind James Cameron's submarine

MrSeb (471333) writes | more than 2 years ago

Science 1

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. Here, ExtremeTech 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."

This is Awesome (1)

$10M coming to james' pockets thanks to the X prize... being aware of some of the challenges that this team has had to face, this is truly an Awesome achievement, Yes it was done in the 60's but this machine is Way more sophisticated than their vessel. Its also better (IMHO) than the Virgin Oceanic's vessel which can only dive while moving forward, this means that if they see anything interesting they will only get a fleeting glance, James On the other hand has 100% control of his position in the water relative to the seabed has the ability to stay down for Hours and hours on end, Oh and its ready to dive now.. and has just completed a dive to 8000m http://deepseachallenge.com/latest-news/cameron-to-walsh-on-record-8k-dive-youd-have-loved-it/ [deepseachallenge.com] I Like the way james rubbed Chris walsh's nose in it :)
