James Cameron reaches deepest sea point powered by fluid compensated electronics

The director of movies Titanic and Avatar, James Cameron becomes the third person in the world to reach the deepest point in the sea, nearly 7 miles deep Mariana Trench, around 200 miles southwest of the Pacific island of Guam.

The deep-sea is dangerous than space because the RF wireless communication does not work. Even the sonic and ultrasonic have limitations. The challenge was met by using a submarine build exclusively for this called "Deepsea Challenger".

The electronics inside the Deepsea Challenger is referred as fluid compensated electronics. The 70 bread-loaf size batteries are housed in a plastic case immersed in a bath of silicon oil, enabling the electronics to be exposed to high water pressure without coming in direct contact with seawater. Deepsea Challenger has used acoustic navigating system to track the sub. When the sub is floating it uses the RF for position tracking.

Deepsea Challenger has used LED light panel, which can illuminate up to 30 meters.
