Aquatic robot seeks and destroys reef-killing starfish

On Australia's Great Barrier Reef, the Crown-of-thorns starfish is the scourge of the deep as it eats and destroys large swathes of coral and threatens the overall health of the reef. This starfish is proving difficult to find and eradicate with conventional methods, so Queensland University of Technology researchers have created a hunter-killer robot – dubbed the COTSbot – that's designed to automatically search out and destroy these aquatic pests.Read More

Tetra-POD clamshell trailer pops open into a boat

At first look, the Tetra-POD is a large, capable ATV trailer that can haul gear, tools and debris as an open tub or an enclosed box. A closer inspection reveals that it's also a boat. With a few simple steps, the lid swings down to join the trailer body in creating a hull that can be motored out onto the open water.Read More

Kingii wrist-worn floatation aid to keep you afloat

Flotation vests save thousands of people from drowning every year, but they aren't of any use if they aren't actually worn. Despite their utility, many people choose not to wear such vests for reasons of comfort, fashion, or space, so Kingii is marketing what is calls the world’s smallest inflatable as an alternative. The focus of an Indiegogo campaign, the wrist-worn device is aimed at swimmers, surfers, sailors, and others who like getting their feet wet.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

Solar-assisted, volcanic-composite sailing yacht navigating world's toughest waters

Carbon fiber has established itself as a wonder material in vehicle construction, with its mix of low weight and high strength being prized for many of the world's most advanced vehicles of land, sea and air. Austrian company Fipofix believes that it's identified a material better-suited to the high seas, saying that its specially processed volcanic fiber-based composite, more commonly known as basalt fiber, offers a better performance-price ratio than carbon fiber or fiberglass and can be recycled after use. The company is in the process of testing the material in some of the world's most extreme marine conditions. Read More

Brainless but not directionless, jellyfish swim against the current

For many people, jellyfish are just an unwelcome addition to a day at the beach. But the gelatinous creatures can seriously affect commercial fishing ventures and even cause the shutdown of power stations when they form into giant "blooms" in the ocean. Researchers at Deakin University in Australia, might be on the way to a solution. Read More

Robot sub beats nets for discovering what lurks at the bottom of the sea

Curious about what's living on the deep sea floor? Well, the Autosub6000 AUV (autonomous underwater vehicle) is helping us find out. Led by Dr. Kirsty Morris, a team at the UK's National Oceanography Centre (NOC) has equipped one of the unmanned submarines with a high-resolution photographic system. As a result, it's claimed to be far more effective at identifying deep-sea life than the usual approach of scientific trawling. Read More
