Cutting Edge

We may be closer to harnessing the power of the sea and air. The world's first hybrid wind-current power generation system will be installed off the coast of Japan later this year.

The Savonius Keel & Wind Turbine Darrieus (SKWID) power generation system being developed by Mitsui Ocean Development & Engineering Company (Modec) is a floating system that shares a vertical floating axis. On the company's Web site (PDF), Modec says the concept will generate double or more power from the same sea surface area as a conventional wind turbine. … Read more

It won't console you as you drown your sorrows in alcohol, but MIT's Makr Shakr robotic bartender can make exactly the drink you're looking for before you've even arrived at the bar.

MIT's Senseable City Lab teamed up with Coca-Cola and Bacardi Rum to bring Makr Shakr to Google I/O, which starts Wednesday in San Francisco. The system allows barflies and frazzled developers alike to personalize their cocktail recipe of choice via a smartphone app, or to choose a libation created by another user, creating a crowdsourced drink menu.… Read more

The race for a lab-grown meat alternative has been on for years. Modern Meadow, for example, has gone after a type of 3D-printed meat using bioprinting techniques. Dutch tissue engineer Mark Post is using stem cells to make a lab-grown hamburger, one that may be actually going down someone's gullet very soon.

Post's Cultured Beef Project has been in development at Maastricht University in the Netherlands for some time thanks to $325,000 in funding from an anonymous donor. Cow muscle stem cells are grown into miniscule strips of tissue. Each strip can take several weeks to grow. It takes 20,000 of these to make a single hamburger. It's a time-consuming and expensive product at this stage of the project.… Read more

The X-47B prototype on Tuesday flew off an aircraft carrier and into the history books.

Today's achievement, the first-ever catapult launch of an unmanned aircraft from the flight deck of a carrier, promises to open up a new chapter in the annals of naval aviation.

The X-47B Unmanned Combat Air System demonstrator launched from the deck of the USS George H.W. Bush at 11:18 a.m. ET off the coast of Virginia. It executed several planned low approaches to the carrier -- a carrier landing will take place at a later time -- and then flew across … Read more

After keeping wildlife and sports photographers waiting for years, Canon has put a price tag on its 200-400mm supertelephoto lens with an unusual built-in 1.4x telephoto extender.

And it's not cheap: $11,799, at least on B&H Photo's preorder page for the Canon EF 200-400mm f/4L IS USM Lens with Internal 1.4x Extender.

Canon one-ups Nikon's $6,400 200-400mm lens with the 1.4x extender, which changes the Canon lens range to 280-560mm with a f5.6 aperture.

The built-in extender can be engaged by flipping a lever, a rapid operation that … Read more

The one-man media machine has landed.

Canadian astronaut Chris Hadfield returned to Earth in a Soyuz descent capsule after his six-month stint on the International Space Station, during which he became an Internet sensation.

Along with ISS crewmates American astronaut Tom Marshburn and Russian cosmonaut Roman Romaneko, Hadfield was extracted from the capsule in the Kazakhstan morning (around 10:31 p.m. ET) following a smooth descent.

Hadfield, the last to emerge from the capsule, waved and gave a thumbs-up once he was propped in a chair in the sunshine.

The trio is to be whisked off by helicopter to … Read more

How do you top months of amazing photos, demos, and tunes done aboard the International Space Station? If you're Chris Hadfield, you cover David Bowie's "Space Oddity" in a showstopping finale.

On the eve of his return to Earth, the Canadian astronaut released a beautifully done video of himself singing the 1969 classic.

Mixed with the help of staff at the Canadian Space Agency, musician Emm Gryner, and others, the cover features a somber piano intro and modified lyrics that reference the Soyuz capsule that will return Hadfield to Kazakhstan. … Read more

Saturday saw a first for NASA and the International Space Station, as two astronauts conducted an impromptu spacewalk to try to locate the source of a problem on the craft's exterior.

The space agency hadn't yet ordered such a spur-of-the-moment maneuver in regard to the ISS, according to the Associated Press, but when crewmembers on the craft spotted ammonia flakes floating through space beyond a window Thursday, the spacewalk was hastily planned.

After Mission Control and the ISS crewmembers prepped intensely -- for less than 48 hours -- astronauts Thomas Marshburn and Christopher Cassidy exited a hatch and … Read more

Imagine carving your way down a particularly challenging slope, your skis kicking up clouds of snow, trees flying by, your death-defying stunts captured perfectly on camera. And you're all by yourself.

How would you pull off such a feat?

Short of those with a film crew on hand, or at least a buddy with a GoPro camera tracking your every move, it's hard to imagine it being possible at all, let alone while you're alone.

But you may not have to imagine it for long.

Next week, a startup called Universal Air will finish shipping out its … Read more
