PLUTO off the coast of San Diego (Image: Paul Wedig, DHS S&T)

When someone mentions drug running, most people probably picture a person coming through an airport carrying a suitcase with a false bottom or with balloons stuffed up their nether regions. We don’t usually imagine things like submarines. Unfortunately, the South American drug cartels not only imagine them, but they build and operate them. To help combat these underwater smugglers, the Department of Homeland Security Science and Technology Directorate (S and T) is operating their own drug-running submarine called PLUTO to develop and test a new generation of detection equipment.  Read More

A new additive based on glycerol helps reduce pollution in marine bunker fuel used in crui...

The bunker fuel used in cruise liners and freighters is some of the cheapest, crudest fuel available. It’s also among the dirtiest. Scientists from the Maine Maritime Academy and SeaChange Group LLC led by George N. Harakas, Ph.D announced at the 244th National Meeting & Exposition of the American Chemical Society that they have developed what they call "Bunker Green" fuel. This fuel uses an ingredient commonly used in food and medicine to reduce sulfur and other emissions in ocean vessels.  Read More

The Mercier-Jones hovercraft design was inspired by luxury sports cars

Frustrated with what they see as stagnation in the evolution of hovercraft design over recent decades, cousins Michael Mercier and Chris Jones have teamed up in an effort to bring the personal hovercraft into the 21st century. As well as a futuristic, streamlined look inspired by high-end sports cars, the Mercier-Jones concept also purports to be quieter, easier to maneuver, and more environmentally friendly than existing craft.  Read More

The SE-35 is waterproof to a depth of 130 feet (40 meters)

The iGills SE-35 is not just another waterproof case for the iPhone, but instead promises to turn Apple’s mobile device into a fully-featured dive computer. The waterproof scuba diving case protects the iPhone down to depths of 130 feet (40 meters) and allows easy underwater usage via six buttons integrated into the design. Users also retain access to the iPhone's camera for underwater shots and on the software side, the SE-35 is offered with a complementary app which features navigation tools and torch, in addition to an automatic dive log.  Read More

Recent developments have rumored that the SeaOrbiter is set to start construction in Octob...

What once seemed science fiction may be becoming a reality. The futuristic SeaOrbiter ocean explorer, a concept conceived by French architect Jacques Rougerie, has been trying to reach fruition for the past twelve years. However recent developments suggest that the vessel is set to start construction this October, with possible completion in 2013.  Read More

The University of Barcelona's Bernat Codina and Andriy Lyasota study data from the wind-pr...

There’s wind in that thar sky ... That’s the sort of thing that – conceivably – might be wistfully said by someone who is tasked with looking for locations in which to locate wind turbines. Their job could soon be getting a little easier, however, thanks to a new balloon-based wind-prospecting system.  Read More

Guinness and Jump Studios have teamed up to turn a submarine into an underwater bar

Two hundred and fifty years ago, brewer Arthur Guinness signed a 9,000-year lease for his St. James's Gate Brewery in Dublin, Ireland. To commemorate this event, the Guinness company could have rolled out a stretch limousine, but it decided to go one better by launching a “deep-sea bar” in the chilly waters of the Baltic off Stockholm, Sweden. Designed by London-based Jump Studios, the modified tourist submarine was commissioned as part of the Guinness Sea Experience competition, that included an underwater trip inside the Guinness sub as a prize.  Read More

The ASV Roboat that will attempt to set a world record while conducting a study of the end...

While sailing can be an activity that is easy to learn, it is difficult to master. Sailing boats need to be constantly tended to quickly respond to changing conditions and for both the novice and the expert, this continual need for adjustments makes sailing a demanding task. That's why the ASV Roboat is an impressive piece of engineering. Packing an array of sensors, communications hardware and solar panels, the ASV Roboat is a fully autonomous, unmanned sailing boat that has its sights set on the current robotic world sailing record.  Read More

A new algorithmic system allows AUVs to reach their destinations faster, or to use less po...

Autonomous underwater vehicles, better known as AUVs, are increasingly finding use in applications such as oceanographic research, mapping, military reconnaissance, and deep-sea oil-well maintenance. As these independent underwater robots make their way through the world’s oceans, they use GPS transceivers to keep themselves on a predetermined route. When they encounter challenges such as cross-currents, one might assume that their best course of action would be simply to power straight across them, in order to travel the shortest distance possible. Engineers from MIT, however, have developed a system that allows AUVs to reach their destinations sooner, by traveling out of their way to “go with the flow.”  Read More

The Air Supported Vessel uses a cushion of air to increase speed and improve efficiency (I...

A European project is developing new Air Support Vessel (ASV) hull designs that allow watercraft to ride on a cushion of air to greatly reduce friction between the hull and the water, resulting in more hull speed for less power than conventional designs. The project is part of a EUR10,000,000 (approx. US$13,225,000) project funded in part by the European Union, the Norwegian Research Council and Innovation Norway, and Norwegian company Effect Ships International AS has recently completed tank-testing in Sweden of two ASV hull models.  Read More
