Two people spent 48 hours in nonstop virtual reality
If you own a virtual-reality headset, you've seen a few health and safety rules. Don't use your VR headset in a moving vehicle, for instance, or make sure to take frequent breaks. For most of us, these guidelines make sense: VR nausea is a very real problem, and limiting our time in artificial worlds is the easiest way to avoid getting simulator sickness. But what if you broke all the rules and decided to stay in virtual reality for 48 hours straight -- eating, sleeping, working and living in a VR headset? Well, then you'd be Dean Johnson, head of innovation for Brandwidth and crazy man who spent two days blindfolded with technology.
Drone flies as both biplane and helicopter using one propeller
There are helicopter drones and fixed-wing drones, but creating a hybrid of both is tricky. Even Parrot's Swing, as clever as it is, needs four propellers and elaborate wings to pull off its stunt. However, TU Delft (with backing from Parrot) has a far more elegant solution. Its DelftAcopter drone doubles as both a fixed-wing aircraft and a helicopter using only one propeller -- its tailless biplane design lets it take off and hover vertically, but gracefully turn into a fast-moving airplane (up to 62MPH) at a moment's notice. It's an incredibly simple design that makes you wonder why someone hadn't considered it for drones before.
Visualized: classic biplane gets a glass cockpit
Waco's YMF-5D biplane may look like an authentically vintage aircraft from the outside, but it's an entirely different story once you strap yourself into the pilot's seat. The plane is available with a number of different "glass cockpit" options, including the top of the line model pictured above that's outfitted with a whole slew of Garmin aviation gear and other 21st century niceties. Of course, that doesn't exactly come cheap - all told, the full glass configuration runs just over $99,000, or over $500,000 including the plane itself (you can see what it looks like after the break).
