Europe's first ultra-deep-sea robotic glider to monitor deep sea pollution

The deep sea is the new frontier for mining, oil exploration, and other industrial activities as they leave the continental shelves for areas miles beneath the ocean surface. Along with this comes greater dangers to the environment, which will require constant monitoring. To provide the needed eyes, Britain's National Oceanography Centre (NOC) and partners are developing the BRIDGES Glider. As Europe’s first ultra-deep-sea robot glider, the craft is capable of reaching 75 percent of the world's oceans to depths of up to 5,000 meters.Read More

Origo folding boat can be assembled in 10-15 minutes

Slovenian brothers Luka and David Dolinšek have joined forces with their father Jure to create a foldable and eco-friendly boat. Following in the footsteps of the Quickboat, Foldaboat and Transporter, the Origo boat comes flat packed, enabling users to transport it directly to the beach or lake before assembling it in under 15 minutes. The family team is currently launching the innovative boat concept through a Kickstarter campaign to bring Origo into full production.Read More

Wärtsilä's new 31 becomes the most efficient 4-stroke diesel engine in the world

Finnish engine manufacturer Wärtsilä must be a fascinating place to visit. The company manufactures some of the most mind-bendingly enormous marine diesel engines in the world, like the record-breaking, 89-foot high, 44-foot long, 110,000 horsepower RTA96-C we wrote about more than 10 years ago. Now, Wärtsilä has another entry in the Guinness Book of Records ... for the world's most efficient 4-stroke diesel engine.Read More

"Whale tails" could use waves to make ships more efficient

Ordinarily, when a ship is heading into waves, those waves cause it to work harder. An experimental new setup known as a "whale tail," however, utilizes wave action to actually help ships move forward, allowing them to use less fuel when tackling rough seas.Read More

Seawolf sub takes your GoPro on an undersea voyage

While there are plenty of aerial drones that show us our surroundings from up in the air, there are far fewer remote-control devices that let us see what's lurking beneath the surface of the water. Although the Aquabotix Hydroview is one, at around US$3,000 it certainly isn't cheap. While still not inexpensive, the newest version of the TTRobotix Seawolf is considerably less pricey – partly because it incorporates the user's existing GoPro actioncam.Read More

Experimental Jet Blade personal watercraft features tilting front suspension

A team from Calvin College, Michigan, is trying to put the "ski" back in "jet ski" with a unique kind of personal watercraft (PWC) that features three skis, a tilting front suspension system and a 650cc engine. Inspired by the dual-ski Wetbike of the 1970s and 80s, and perhaps a little by the bizarre Watercross racing movement, the Jet Blade team has completed prototyping and preliminary water testing.Read More

Submersible photographs WW2 Japanese sub's long-lost airplane hangar

Until the 1960s, Japan's three I-400-class subs were the largest submarines ever built. They were so large, in fact, that they could each carry and launch three Aichi M6A Seiran amphibious aircraft. The idea was that the submarines could stealthily bring the planes to within striking distance of US coastal cities, where they could then take off and conduct bombing runs. Now, for the first time since it was scuttled at the end of World War II, one of the sunken subs' aircraft hangars has been photographed.Read More

SipaBoard stand-up paddleboard uses a motor for extra speed – and to inflate itself

While stand-up paddleboards are usually a lot of fun to use, they can be a hassle to transport and store. That's why we've seen ones that can be folded up and disassembled. The SipaBoard, however, takes yet another approach – it's inflatable. An onboard electric motor pumps the air into it for you, plus it also powers an integrated jet drive that provides paddlers with a boost. Read More
