Underwater

The University of Maryland has won the 11th Annual International Autonomous Underwater Vehicle Competition, in San Diego California. The event is organized by the Association for Unmanned Vehicle Systems International and the Office of Naval Research, and challenges universities to design and build an AUV capable of navigating realistic underwater missions.  Read More

A giant rubber tube known as the “Anaconda” may present an viable solution to the challenge of generating electricity from the power of ocean waves. Under development in the UK, the simple design means it would be cheap to manufacture and maintain, resulting in clean electricity at a lower cost than other types of wave based energy production.  Read More

Scientists at the University of Washington have created a sub-surface robot that uses fins instead of propellers, and is able to wirelessly communicate enough information to move in tandem with other units. The Robofish is roughly the size of a 10-pound salmon and will be used to track animals and map the bottom of the ocean.  Read More

Best known for its ventures in land-based military vehicles and home-helper robots, iRobot has now branched out into the autonomous underwater vehicle (AUV) market. The company will commercialize "Seaglider" technology from the University of Washington, a system which assists civilian, academic and military personnel in taking oceanographic measurements at a lower cost than traditional research vessels or moored instruments.  Read More

April 13, 2008 We've written before about H2O Audio's waterproof iPod accessories that let you pump out some good adrenaline tunes while you push through your swimming workout. Now, as America, China and Australia prepare to do battle for aquatic world supremacy in Beijing, the company has teamed with U.S. backstroke world record holder Natalie Coughlin to produce the iSH2 - an integrated waterproof case and headset for the iPod shuffle that works up to 10 feet (3m) under water.  Read More

February 28, 2008 Looking to beat the heat this summer by installing your own swimming pool? We thought we would give you a taste of what you almost certainly can't have when designing your dream backyard aquatic paradise. Firstly, there's the world's largest pool with an area equivalent to an incredible 6,000 standard-size 26 ft long domestic pools located at the San Alfonso Del Mar resort in Chile, and, going to the other extreme, there's Belgium's amazing 100 foot deep, 660,000 gallon (and heated!) Nemo33 dive pool.  Read More

January 29, 2008 Ocean Thermal Energy Conversion uses the temperature difference between surface and deep-sea water to generate electricity – and though it has an efficiency of just 1-3% - researchers believe an OTEC power plant could deliver up to 250MW of clean power, equivalent to one eighth of a large nuclear power plant, or one quarter of an average fossil fuel power plant. Architect and engineer Dominic Michaelis and his son Alex, along with Trevor Cooper-Chadwick of Southampton University are developing the concept with plans of putting the theory to the test on an unprecedented scale by building a floating, hexagonal Energy Island that will harness energy from OTEC, as well as from winds, sea currents, waves, and the sun.  Read More

October 10, 2007 The Seabob electric underwater propulsion device captured our imagination earlier in the year, acting like a 20kmh powered bodyboard and allowing users to dart along coral reefs and the ocean floor like they were born with fins. We’ve since discovered that the company has now produced a souped up version called the Cayago Magnum with 2½ times the available power or endurance. With the existing Seabob models already setting a pretty thrilling pace for leisure use, the high performance Magnum will be pitched as a military and special forces tool that will enable operatives to move exceptionally quickly from point to point, underwater and in total silence.  Read More

August 21, 2006 Lockheed Martin telegraphed its intention to become a significant supplier of unmanned systems technology during a press briefing at the National Press Club in Washington, D.C. this week. In showcasing its latest developments in unmanned systems technology and its progress into the future net-enabled environment, it discussed a broad range of unmanned and autonomous technologies, from the recently introduced Polecat and other unmanned aerial systems, to surface vessels such as the Protector (covered earlier this week here) and subsurface prowlers, such as the Sea Talon. During the conference Lockheed VP Frank Murno acknowledged that the company was considering a hybrid version of its F-35 Lightning II Joint Strike Fighter – where it could be operated with or without a human pilot as required.  Read More
