DARPA's ocean-faring drone will hunt enemy submarines
Remember DARPA's aquatic drone that would roam the oceans, hunting down stealthy enemy submarines? Defense contractor Leidos has announced that construction has begun on the first of the fleet, with test cruises expected to begin at some point in 2015. Thanks to both a lack of crew facilities and a modular design, the ACTUV is expected to only take around 15 months to build. With no human operators, however, the drone's artificial intelligence needs to be rock solid to ensure it doesn't kick off another world war. That's why DARPA's been crowd-sourcing amateur submarine tacticians for their ideas with its ACTUV Tactics Simulator game. Yes folks, that time you recreated The Hunt for Red October in a simulation game is now locked inside the Navy's latest weapon. Sleep tight.
Fleet of underwater gliders could improve global weather forecasts
While our entire climate model is based on the world's ocean currents, there's a surprising lack of detailed measurements of their movements. Researchers from Rutgers and elsewhere want to rectify that with the Challenger Glider Mission, which will launch 16 unpowered, autonomous submarines later this month. As with past adventures, the 7-foot-long craft will ply deep currents across 80,000 square miles in five ocean basins, using buoyancy changes and fins for propulsion and navigation. From there they'll transmit real-time current, temperature and salinity data to the Iridium satellite network. Combined with other observational methods, that could help scientists refine current climate models and improve forecasting. Researchers will also gauge the health of our planet's oceans using phytoplankton measurements -- definitely a hot-button issue at the moment.
Navy launches a drone from a submarine's torpedo tube
We can think of few sights more ominous than watching an unmanned aerial vehicle emerging from an egg-like canister in the middle of the ocean, but that may well be the future of military reconnaissance. The US Naval Research Laboratory sent out a note today, informing the world that it has managed to launch a drone from submerged sub and have it fly around for an hour. It's not the first time the Navy's considered such a feat, but this time out, the drone traveled in a "Sea Robin" capsule fired from the sub's torpedo tube. Possible applications for the drone include surveillance, gathering intelligence and, naturally, delivering small packages to Prime members living in the middle of a large body of water.
Google Street View can now take you on a tour inside a naval submarine
Ever wonder what it's like to wander the narrow corridors of a 50-year-old Oberon-class British submarine? Well, you can now embark on a digital tour of the HMS Ocelot via Street View, which has become the first submersible to be fully documented by Google. Even without its backpack-worn trekker units, the company has mapped-out the Ocelot's complex control room, restricted sleeping quarters and even its six torpedo tubes, which have thankfully been out of service for more than 20 years. It also lets you take a tour of the dockyard from which the submarine was launched. Hit up Google Street View to begin your personal guided tour, just be sure to mind your head when navigating those hatches. [Image Credit: wimbledonian, Flickr]
Fujitsu made a Windows 8 tablet with a fan that works underwater
Hidden within Fujitsu's autumn lineup for Japan was another waterproof tablet, but this one had something a little different -- an extractor fan that survives underwater. The 12.5-inch QH77/M will need it, because it runs on Intel's 1.6GHz Core i5-4200U processor, which (nearly always) requires a degree of cooling. The fan will halt when the tablet is submerged, apparently, although our allies at Engadget Japanese, asking the questions that count, posited whether the fan offered enough thrust to move the tablet "like a submarine," if left to whir away. Fujitsu's spokesman said that they tested that themselves -- like any discerning company should. Unfortunately, the tablet is "too heavy" to move along the depths of the ocean your bathtub.
Spymaster's Orcasub is a $2 million submarine for two
Sure, you could use an ROV to feel like a regular Jacques Cousteau (or James Cameron, for that matter), but nothing beats the real deal: a personal submarine. UK department store Harrods used its Technology Showcase 2.0 event to highlight a mockup of Spymaster's Orcasub: a made-to-order $2 million submarine that can drop up to 2,000 feet into the briny depths. A total of two passengers can climb aboard the 4-ton, 22 foot-long submersible thanks to a pair of 360-degree domes that offer 80 hours of life support for each occupant. The battery-powered sub is piloted by using two foot pedals and a joystick, and handles somewhat like an aircraft since it was built with the principles of flight in mind. Orcasub comes outfitted with sonar for collision avoidance, a digital long-range communications system and a 60,000 lumen LED lighting rig. What you see above is just a miniature, but Spymaster is taking orders for the real, full-size McCoy. In fact, folks who'd like to dive deeper can put in a request for pricier models, with the most expensive version nabbing explorers a maximum depth of 6,000 feet for a cool $9.32 million. If you ask us, this sounds like a perfect escape vehicle for any luxury yacht worth its salt. Hit the source link for Pocket-lint's photo gallery of the craft.
SAIC shows how DARPA's submarine-tracking drone ship finds its silent targets (video)
Some of us have been feeding advice to DARPA's ACTUV sub-tracking drone project for more than a year, but we haven't had a in-depth look at how the autonomous ship will go about its business, especially when chasing very silent diesel-electric subs. Thankfully, craft designer SAIC has stepped in with a detailed video tour. If there's suspicions that a diesel sub is in the area, the US Navy can deploy sonar buoys that give the ACTUV an inkling of where to go first. After that, the drone takes over with both long-range and short-range sonar. The vehicle can gauge the intent of ships in its path (with human failsafes) and hound a target for up to 13 weeks -- either letting the Navy close in for an attack or, ideally, spooking the sub into avoiding conflict in the first place. While ACTUV won't hit the waves for years, there's a promise that we'll always know about underwater threats and deal with them on our own terms.
US Navy deploys SeaFox submarines to Persian Gulf for universal mine control
Tasked with mine detection and eradication in the Persian Gulf, the US Navy has sent a fleet of unmanned submarines to help keep the Strait of Hormuz open in Iran. Dubbed the SeaFox, each vehicle houses an underwater TV camera, sonar and a dose of explosives. Tipping the scales at less than 100 pounds, the subs are about four feet in length and are controlled via fiber optic cable that sends the live feed back to the captain of each ship. SeaFoxes can dive to depths of 300 meters and boasts a top speed of six knots. The units are thrust into action from helicopters, small rubber boats and off the rear of minesweepers and are capable of disposing of the aforementioned weapons of both the floating and drifting sort. There is one small catch: the $100,000 submarine destroys itself in the process, making each successful trek a suicide mission of sorts.
Remote-controlled Aquabotix HydroView takes underwater HD video, Mrs. Puff calls insurance agent
Using an iPad to control your music system? Been there, done that. Using an iPad to control a submersible that also records underwater video in 1080p? Oh, the possibilities. Aquabotix is giving Jacques Cousteau wannabes the ability to shoot the watery depths all the way down to 150 feet as its underwater doohickey -- the HydroView -- officially goes on sale. Measuring 14.6 x 19 x 7 inches and weighing nine pounds, the submersible comes with LED lights, a three-hour battery and a top-side box that connects with a cable tether. The box also allows users to communicate with the HydroView via an iPad, Mac or PC. Besides getting video proof of, say, which swimmers ate too many bean burritos for lunch, the submersible can also take pictures and gather data about water conditions. Top speed for the submersible is five knots -- one knot when going in reverse. Just make sure you don't channel your inner SpongeBob while remotely driving the thing. Although it's not in the same league as Rinspeed's submersible Elise, the HydroView still doesn't come cheap at $3,995 a pop. Check out the official PR and, uh, low-def video of the diminutive diver in action after the break.
Open source mini sub appeals to our inner Steve Zissou
Quadrocopters haven't exactly opened the skies for DIY exploration so much as they have for acrobatic feats, but the OpenROV project is hoping to make the briny depths friendlier for aspiring explorers and educators alike. The open source rover, spearheaded by NASA engineer and researcher Eric Stackpole, sinks to depths of up to 300 feet (100 meters), runs on eight C-cell batteries for approximately 1.5 hours and can clip by at three feet (one meter) per second. Within the laser-cut acrylic frame, a sealed cylinder houses a BeagleBone, HD webcam and LED lights. This all weighs in at 5.5 pounds and is piloted using a web browser and video feed. The footage is then piped up to a laptop that tethers the vehicle to the shore. Pre-orders for OpenROV 2.3 kits will be taken through Kickstarter later this summer at $750 apiece, though there are plans to sell fully assembled units. For now, explorers can register their interest at the link below and impatient Jacques Cousteaus will be pleased to know that all files necessary to build version 2.2 are available to download now.
James Cameron journeys to the Challenger Deep, lives to tell the tale in 3D (video)
It's easy for life to imitate art when you're armed with near billion dollar coffers. Taking a cue from his 1989 hit, The Abyss, James Cameron made a solo plunge down to the deepest part of the Earth -- a spot seven miles below sea level known as the Challenger Deep -- and recorded his journey in 3D for our slack-jawed, couchbound amusement. The terrain, described by Cameron as both "desolate" and "lunar," is part of the Mariana Trench and had remained unexplored by humanity since the Trieste first touched down in 1960. That two man crew, hampered by the technological advancements of the time, didn't have the luxury of capturing the undersea trek, so when Cameron's footage finally hits screens, it'll be the planet's first peek at a truly alien world. Conspiracy theorists and New Age-y types will be disheartened by the lack of any reported close encounters of the aquatic or Steve Zissou kind, as the blockbuster filmmaker only spied a variety of small, whitish and, predominantly, eyeless creatures. The trip was seven years in the making, and involved the construction of the Deepsea Challenger -- the high-tech mini-sub which carted Cameron safely to the Pacific Ocean's depths and back. Curious to see what only the world's richest can experience first-hand? Then click on past the break for a brief docu-tease.
It's not a flying fish, it's a submarine-launched UAV
VTOL may be old news already, but here's another great USP for any UAV: the ability to launch from a submerged submarine. The technology is still in development, but the Navy wants to try it from periscope depth during exercises in the Pacific Ocean next year. If all goes to plan, a Switchblade folding-wing drone will be ejected from the submarine's trash disposal unit and then carried to the surface by an SLV ('submerged launch vehicle'), which will keep it dry, point it into the wind and then hurl it heavenwards so it can go a-snooping. Whether the experiment succeeds or fails, we've glimpsed a worrying possibility: submarines are capable of dumping their trash right into the ocean. Until now, we sort of assumed they took it home with them.
Duke University's underwater invisibility cloak stills troubled waters
Everyone's jumping on the invisibility cloaking bandwagon these days, but no one's quite managed to fully deliver on the promise. The same goes for two Duke University researchers who believe their mesh casing could grant the gift of concealment to underwater craft -- submarines, anyone? According to the proposed model, a specially designed shell punctuated by complex patterns of permeability and millimeter-sized pumps would eliminate the drag and turbulent wake caused by an object as it moves through the water. Utilizing the penetrable gaps in the case, water would at first accelerate, and then decelerate to its original speed before exiting -- rendering the fluid around the object virtually undisturbed. Now for the bad news: the design doesn't quite work for large-scale, real-world implementations -- hello again, submarines -- since the tech can only cloak small structures, like "a vehicle one centimetre across... [moving] at speeds of less than one centimetre per second." It's a massive bummer, we know, but we're getting there folks -- you just won't see it when it actually happens.
Triton 36,000 submarine to plumb ocean's deepest depths, comes in yellow (video)
Richard Branson's not the only one eager to explore that other 70 percent of the world. Triton Submarines has designed a three-passenger sub able to dive 36,000 feet, reaching the deepest part of the world's oceans. And while Sir Richard envisions a spaceship-like craft, Triton's design evokes old school bathyspheres: it's a glass globe. Of course, water pressure poses a serious engineering challenge when you descend seven miles below the surface -- the last manned sub to reach that depth had only a single, small window made of plexiglass. The current design uses borosilicate glass (like those transparent displays we, um, saw through a while back) that actually grows stronger as depth pressure increases; it took eight months of careful heating and cooling to produce. Assuming the glass holds, it will take about 75 minutes to reach the bottom of the ocean. Anyone considering a test run should check out the PR video after the break, showing Triton's other submarines in action.
Download DARPA's sub-hunting sim, help train its ACTUV automaton
DARPA dabbles in all matter of defense drones, and it's no stranger to leveraging the wisdom of the masses to help develop tomorrow's military machinery. The agency's latest program to go the crowdsourcing route is its Anti-submarine Warfare Continuous Trail Unmanned Vessel (ACTUV), and it wants you to help develop the software that'll control the thing. DARPA's borrowed a bit of the Sonalysts Combat Simulations Dangerous Waters game to create the ACTUV Tactics Simulator, where players complete missions tracking a target sub while navigating through and around commercial ocean traffic. Would-be captains can then choose to submit their strategies and game data to DARPA for use in shoring up the autonomous seabot's strategic submarine pursuit software. Hit the source link for a free download and dive into the sub-hunting action.
Richard Branson launches Virgin Oceanic to explore the ocean's depths
Sir Richard Branson may have already branded his Necker Nymph aero submarine with the "Virgin Oceanic" moniker, but he's now finally taken things to the next logical (and ambitious) step. He's just announced a new, full-fledged venture of the same name, which promises to do to nothing short of dive to the deepest part of each of the Earth's five oceans -- all within the next two years, no less. That will be done with the one-manned sub pictured above, which was designed by Graham Hawkes and will be piloted by Chris Welsh on its first dive to the bottom of the Mariana Trench later this year -- those two are Branson's partners in the venture, and Branson himself is set to pilot the sub on its second mission to the Puerto Rico Trench. Not surprisingly, one of the team's goals is to set a few world records, but they're also planning to conduct some scientific research along the way, and are already musing about future vehicles that could collect samples and allow for more extensive research. Head on past the break for a teaser video, although we're told it should not be assumed to reflect an actual mission.
Tiny EGO pseudo-submarine for the super rich is aptly named
Imagine you are so rich you want your own underwater pleasure vehicle, and you don't mind dropping what is likely to be a boatload of cash get it, today may be your lucky, lucky day. A company called Raonhaje has developed the EGO mini-submarine which floats atop the water, but which boasts a submersible capsule for passengers to check out what's going on beneath the surface. Sounds intriguing, right? Sure does! The relatively eco-friendly EV vehicle cruises at just less than five knots for four hours on a full charge. There are no details on price yet, but we expect it will be quite a lot. Video of the rendered model is after the break.
Inhabitat's Week in Green: of pedal-powered submarines and soda-powered fuel cells
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. This week, California saw a tremendous boost for solar power as the nation's first solar thermal plant in two decades was approved for Kern County. We also saw several incredible new approaches to generating alternative energy as researchers took crucial steps towards tapping the skies for lightning power and scientists unveiled a fuel cell battery that can be powered by soda. And if you can barely contain yourself at the prospect of pop-powered batteries, relax -- a team of scientists is also working on using urine to create low-cost fuel cells. This week we also watched green transportation take a plunge beneath the sea as French engineers unveiled an awesome pedal-powered submarine. Our neighbors to the north also broke news as students at the University of British Columbia embarked upon a record-setting trip across Canada in an electrified VW Beetle and three Canadian schools announced plans to create a car out of cannabis - hopefully it doesn't go up in smoke. Finally, we took a (sobering) look at the havoc that poor public transportation planning can wreak: a massive traffic jam in China that extended for more than 60 miles and 9 days. Speaking of students, here are a few projects to get you energized for the coming school year: a German tank armory was recently transformed into an ultra-modern solar-powered school, and we showcased some of the world's most incredible student-built structures. In other news, we brought you two dispatches from the realm of wearable tech - a new energy-harvesting film that could wire your wardrobe and a line of clothing that lets you send and receive phone calls. Can you hear me now?
Robotic yellow submarine finds massive river under the sea, tons of other trippy stuff
Researchers at the University of Leeds have employed a robotic yellow submarine to fund and begin documenting a massive river under the sea, known as a submarine channel -- the first ever directly observed. The river is so large that if it were on land, it would be the sixth largest river in the world. The torpedo-shaped autosub itself is a 23-foot long, unmanned craft which can be programmed to stay just safely above the channels where they'd encounter damage. It's equipped with an underwater speed camera which enable the team to observe in detail the flows within the channel. While little is known about what kind of lifeforms may lurk in these waters, the team's research puts science a little closer to understanding these unique rivers, and its full report will be published later this year in Geology.

UK defense firm pumps data through solid submarine walls
Wireless power may still be on the drawing board, but wireless data is here today, and a UK defense contractor has figured out a way to pipe the latter through several inches of steel. Using a pair of piezoelectric transducers on either side of a watertight submarine compartment, BAE's "Through Hull Data Link" sends and receives an acoustic wave capable of 15MHz data rates, enough to transmit video by essentially hammering ever-so-slightly on the walls. BAE impressed submarine commanders by streaming Das Boot right through their three-inch hulls, and while metadrama is obviously the killer app here, the company claims it will also save millions by replacing the worrisome wiring that's physically routed via holes in a submarine's frame. See the company's full US patent application at our more coverage link.
