Diving

Well-known film director and deep-sea explorer James Cameron is no stranger to setting records, but this time, instead of box office gross, he's setting his sights on something more akin to a single-handed lunar landing - a solo trip to the ocean's deepest point, the Challenger Deep in the Mariana Trench off Guam. Billionaire entrepreneur Sir Richard Branson is hard on Cameron's heels but it appears almost certain the genius behind the blockbusters Titanic and Avatar will be the first to get there alone - he just snagged the record for deepest solo dive off Papua New Guinea on March 6th with a depth of 26,791′ (8.2km).  Read More

The Seabreacher not only looks like a dolphin, it can dive and jump like one, too

Gizmag covered this amazing dolphin-like watercraft almost three years ago. At that stage, the Seabreacher - a unique submersible vessel - was just a prototype. Now, you can own your own, make like Flipper, and dive, roll and jump while staying warm and dry in the comfort of the sealed cockpit. Oh, that is, if you have a cool USD$50,000 burning a hole in your wallet.  Read More

February 3, 2006 Air and water are two of life's staples - interestingly, two of the best ideas we've ever written up involve both. Airwater machines extract water from the air and now there's a machine which can extract air from water, on-the-fly. Isreali company LikeAFish has developed a new technology which will enable a new paradigm in underwater exploration and living. Likeafish’s tankless diving technology is able to extract air from water and could revolutionise scuba diving, offering unlimited dive time and no need for expensive and inconvenient refills. The appropriately-named company uses a method similar to a fish’s gills to extract the dissolved air present in all seawater to offer an indefinitely sustainable supply of oxygen to scuba divers, submarines and underwater habitats. The device uses a battery-powered centrifuge to lower the pressure of seawater in a sealed chamber, enabling the air to escape, in a similar manner to opening a bottle of lemonade. After separation in the centrifuge, the air is transferred to an air bag for use by the diver. The first unit will be installed in Lloyd Godson’s BioSUB this year – the BioSUB is the world’s first self-sufficient, self-sustaining underwater habitat.  Read More

The Surf Shark helps humans swim like a fish

October 27, 2005 NEW IMAGES UPLOADED The Surf Shark and the Electric Dolphin are electric aquatic vehicles with a difference – instead of holding onto them as with all other diving and swimming aids, the Shark and Dolphin attached to your feet and propel you from behind, just like a fish and nearly as fast. The Surf Shark is the pick of the pair for speed, having two motors, each delivering 82 pounds of thrust and capable of pushing a swimmer through the water at more than 5 knots (10km/h) – that’s roughly twice the speed of Grant Hackett at World Record 1500 metre pace. The Dolphin has just one motor but makes up for its lesser speed with twice the life, being capable of delivering about half that speed for over an hour before needing a battery swap.  Read More

This remote controlled submersible is designed to give you first hand experience of the world beneath the waves without so much as dipping a toe in the briny. Spyfish STV is equipped with two cameras, three thrusters and floodlights that enable it to dive to depths of 150 meters and transmit video images back to the surface in real-time.  Read More

Shark Shield makes it safe to go back in the water

Man's love affair with the surf has always been tempered with the fear of the ultimate blue water predator, the shark. Until now that is... a new Australian invention makes it safe to go into the surf or sit "out the back" with your legs dangling in far greater safety. Adelaide-based SeaChange Technology has released the Shark Shield, a book-sized device that straps on to the thigh and repels sharks by emitting an electrical field via trailing antenna. A Sharks detects this electrical field through sensory receptors on its snout, initially causing mild irritation and as it swims closer, muscular spasms that drive the shark from the area. The Shark Shield is available in a general-purpose unit for surfing activities or as a kit designed specifically for divers which has the two electrodes at different points - one on the ankle and another on the scuba cylinder - creating a protective field all around the body.  Read More
