The GroundBot is a spherical sentry designed to roll up to 6 mph through just about anything—mud, sand, snow and even water. Two gyroscopically steadied wide-angle cameras and a suite of sensors give remote operators a real-time, 360-degree view of the landscape, letting them zoom in on prowlers or detect gas leaks, radioactivity and biohazards.

With the wingspan of a B-29 bomber, the WhiteKnightTwo is the largest all-carbon-fiber aircraft ever built. Its mission is to carry a smaller craft, SpaceShipTwo, and drop it at 48,000 feet, where it will blast off into suborbital space with paying passengers—in 2010, if all goes well. [ Read Full Story ]

In 2002 I got my first digital pen, which captured handwriting as an image file, eliminating the need for paper notes. Or so I thought. Unfortunately, my full-speed penmanship was just as illegible in electronic form. Six years later, Livescribe solved that problem. Its Pulse uses the same technology to track its location on specially printed paper, but it pairs the text with an audio recording. [ Read Full Story ]

In congested cities like Tokyo, there’s barely room to swing a wrecking ball, and neighbors hate the caustic dust that implosions kick up. So the Japanese construction company Kajima developed a tidier technique, which it first used this past spring to take down a 17-story and a 20-story office tower: Knock out the ground floor, lower the building on computer-controlled hydraulic jacks, and repeat.

“Boss,” the brainchild of Tartan Racing (a collaboration between Carnegie Mellon University and General Motors), was the winner of the 2007 Darpa Urban Challenge, a competition of autonomous vehicles. The mission: execute tricky merging, passing and parking maneuvers as quickly as possible, while obeying California-state traffic laws. [ Read Full Story ]

Zoning laws often forbid tall wind turbines. The Windspire captures breezes at 30 feet and below with a design in which blades run up a pole’s length and spin around it. Contoured airfoils make the Windspire the first vertical-axis turbine that can start in slow winds without help from a motor or inefficient scoops or wings. [ Read Full Story ]

Construction on the $10-billion behemoth—housed 300 feet underground in a 17-mile circular tube—spanned 14 years and required the efforts of 10,000 engineers and physicists. But its real engineering feat comes from the 1,200 magnets—each 35 tons in weight, 50 feet long, and powerful enough to crush a bus between them—that steer a stream of protons traveling at nearly the speed of light. These magnets are powered by 4,700 miles’ worth of superconducting niobium-titanium cable, and work only when cooled to 3.4˚F above absolute zero, colder than deep space. [ Read Full Story ]

This Web site uses ordinary photos—whether of national monuments, scientific specimens or your vacation—to build a 3-D view that you navigate as if in a videogame. Photosynth analyzes dozens of shots to find overlapping areas and piece them together. [ Read Full Story ]
