This 18-inch off-roader is made for play. But it packs an engine, starter and sensor system that are just like a real racecar’s—at a tenth of the size

Gas-powered remote-control cars provide realistic racing fun. They burn a gasoline-like fuel called nitro (made of methanol, nitromethane and lubricant) with miniature internal combustion engines. Losi's Ten-T gets even more authentic by adding a starter that works like a diesel engine's. Nitro cars are usually hard to start: You have to pick them up, use a hand-held motor to spin the engine, and simultaneously work the remote's throttle. With the Ten-T you just hit "start" on the remote.
Bosch reinvents the common nailer, making a smaller tool with the nail-driving power of the big guns

Pneumatic nailers can slash the time it takes to fasten everything from window trim to roof rafters. The basic guts of the tool haven’t changed since the 1960s: Compressed air pushes a piston that drives a rod, forcing nails deep into wood, before the tool resets for the next nail. Now Bosch has figured out how to make a nailer that’s 20 percent smaller while boosting power by 10 percent, so it can drive nails into hard woods like walnut with less pressure than other guns.
A massive floating laboratory is attempting to drill through four miles of seabed to take samples of the Earth’s mantle

The world’s deepest drill is about to get taller—tall enough to dig into Earth's mantle. Already, the Chikyu research vessel is capable of fetching samples at depths of 23,000 feet below the seabed, two to four times that of any other drill. In 2007, off the coast of Japan, it became the first mission to study subduction zones, the area between tectonic plates that is the birthplace of many earthquakes. Over the next three years, scientists will tack on at least an extra mile of drill and attempt the most ambitious mission ever: piercing the Earth’s mantle.
It’s midnight. You’re a cop patrolling the wrong side of town when you spot a mugging. The assailant is about 40 feet away, out of range of your stun gun. You shout, but he darts down an alley. It’s a dead end. The crook picks up a bottle, hurls it at your head, and makes a break for the street. You draw your gun.
To take advantage of the strong winds that blow over the ocean, this gearless turbine uses a giant ring of magnets and 176-foot blades

There’s enough wind energy along our coastlines to power the country four times over, and the race is on to build the best offshore turbines to capture it. Manufacturers worldwide are experimenting with two techniques: ever-longer blades to harness more gusts, and simplified drivetrains (including new generators) that slash the need for costly repairs at sea. GE’s upcoming machine, slated to go online in 2012, will combine both into one package.
A robotic rocket that can repeatedly take off and land vertically would have endless uses: As a lunar lander that can park itself at a fuel station, gas up, and immediately relaunch to ferry supplies elsewhere on the moon. Or as a space-tourism craft that can touch down safely on helicopter-like landing pads. That’s why four years ago, NASA opened the $1-million Northrop Grumman Lunar Lander Challenge, a competition designed to encourage private companies to develop low-cost rockets with the precision, power and quick turnaround needed for moon and other missions.
Flashlight: Surefire’s military-grade torch shines more than 500 yards, even though it’s not much bigger than your hand. Its LED combines four light-emitting chips on one circuit board, instead of giving each its own electronics and case. The result is a concentrated yet efficient beam. A processor regulates power to run for 100 minutes on high, 500 on low. SureFire M3LT $450; surefire.com
A piece of plastic the size of a credit card, combined with a book-size gadget, can diagnose as many deadly diseases as big laboratory machines can—but quickly, cheaply and in remote locations

Most blood tests require shipping vials off to a lab, followed by several days of nail biting. This kit, one of the first that can diagnose multiple diseases on the spot, shrinks an entire lab into a two-piece portable package that even novices can use. A disposable, $1 plastic card, formed through injection molding, holds miniature versions of test tubes and chemicals. In place of technicians or $100,000 machines, a battery-powered, $100 gadget mixes the molecules.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
