NASA heads underwater to test concepts for future asteroid mission

By - June 12, 2012 4 Pictures
With the first manned mission to an asteroid planned for 2025, NASA has sent an international group of “aquanauts” to the ocean floor off the Florida coast to test concepts for such a mission. The four-person crew will spend 12 days 63 feet (19 m) below the surface of the Atlantic Ocean in the Aquarius lab located in the Florida Keys National Marine Sanctuary as part of the 16th excursion of the NASA Extreme Environment Mission Operations (NEEMO) program.

Special solar cells produce electricity from underwater sunlight

Although solar cells are proving indispensable for powering things such as electronic sensors on dry land, sensors located underwater have typically had to rely on batteries, or electricity piped in from photovoltaic panels situated above the surface. That could be changing, however, as scientists from the U.S. Naval Research Laboratory have recently developed functioning underwater solar cells. Read More

OpenROV could open up the world of underwater exploration

By - June 6, 2012 7 Pictures
Underwater remote-operated vehicles, or ROVs, are almost impossibly fascinating. They’re controlled by a surface-based operator, who watches their real-time video feed and pilots them via a long umbilical cable. Although the big-league multi-million-dollar ROVs are used for things such as exploring the wreck of the Titanic or studying hydrothermal vents, hobbyists have quite a bit of fun using their own home-built versions just to see what’s under the surface of the local lake. Unfortunately, even to build one yourself, you need to be pretty technically skilled. That could change, however, as the OpenROV project is developing “easy to assemble” kits – it may even provide li’l ROVs that are ready to go, right out of the box. Read More

Architects transform submarine into a bar

By - May 18, 2012 12 Pictures
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.

"Dolphin speaker" could pave the way for human-cetacean communication

While there’s little doubt that dolphins are saying something to one another with all their clicks, squeals and whistles, we’re still not entirely sure just what it is that they’re communicating. We may be getting closer to figuring it out, however, as Japanese scientists have created an underwater speaker that’s capable of playing back the creatures’ entire acoustic range. The next step - see how they respond. Read More

GoPro releases Dive Housing for HERO actioncams

Although you may have seen plenty of underwater videos shot using the GoPro HERO actioncam, its lens was never really designed for underwater videography – as we previously illustrated in a video report, the footage sometimes looks a little fuzzy. As of today, however, would-be Jaques Cousteaus can now purchase a dive-specific GoPro housing, that promises sharp images. Read More

Dubai Water Discus hotel will allow guests to sleep underwater

It seems the construction boom in bustling Dubai is far from over – already home to several world record-holding projects, including the tallest building (for just a little while longer), the largest shopping mall and biggest man-made island, plans are now afoot to construct what will likely be the world's largest underwater luxury hotel, the Water Discus. Several years ago, we reported on another such ambitious project, Hydropolis, which sadly never got past the blueprint stage. If Polish company Deep Ocean Technology's (DOT) plans come to fruition, however, guests could one day find themselves asleep beneath the waters of the Persian Gulf. Read More

TAT7 case keeps your iPhone camera clicking underwater

There was a time, back in the days of film cameras, when the only ways of getting underwater photos were to buy an expensive waterproof SLR, an expensive waterproof housing for a regular SLR, or a cheap disposable waterproof camera that took horrible shots. Now, all you have to do is buy a housing like the TAT7 iPhone Scuba Case, and start snapping high-res pics – assuming you’ve got the phone to go with it. Read More

Ocean-powered robotic jellyfish could theoretically run forever

By - March 21, 2012 4 Pictures
Researchers have created a silicone submarinal robot that gets about by mimicking the motion of a jellyfish. The robot is powered by heat-producing reactions catalyzed by its surface, and using hydrogen and oxygen present in the water as fuel. It's claimed that that the Robojelly, so named by its Virginia Tech creators, could run indefinitely, effectively drawing energy from the water in which it swims. Read More
