Casio develops pocket-size transceiver for Scuba use
Casio announced it has developed an underwater transceiver that lets users have spoken conversation via ultrasound and bone conduction technology when scuba diving. Casio says the device is small enough to attach to the strap of a diving mask so divers can converse normally with the scuba regulator in their mouths.

Scuba tank-powered dirt bike
What all can you do with a scuba tank? Dive, of course, but an engineering school graduate in Australia used it to power a dirt bike. The O2 Pursuit bike, which looks quite impressive (you first don't even see the tank), runs over 60 miles on a full scuba tank, and can reach almost 90 mph top speed.
