Joseph Longo's Plasma Converter turns our most vile and toxic trash into clean energyâ€”and promises to make a relic of the landfill

It sounds as if someone just dropped a tricycle into a meat grinder. I'm sitting inside a narrow conference room at a research facility in Bristol, Connecticut, chatting with Joseph Longo, the founder and CEO of Startech Environmental Corporation. As we munch on takeout Subway sandwiches, a plate-glass window is the only thing separating us from the adjacent lab, which contains a glowing caldera of "plasma" three times as hot as the surface of the sun.
Watch as souped-up power tools tear down a 60-foot track (and through a flaming hoop!) in our exclusive video

For a closer look at the wildest repurposed rigs, launch the photo gallery by clicking 'View Photos' at left. And to see what happens when the power-tool racers come across a gas-powered ring of fire and a few cold beers, see the video at the bottom of the page.
It´s a rocket. Stuck through the back of a skull, sitting on an aging belt sander rigged to a pair of sawed-off skis. And it can haul butt down a track.
The newest pocket cams use stabilization to save you from your shaky hands

The smaller your camera, the more susceptible it is to even the slightest tremble, which can leave your photos looking like Impressionist paintings. Fortunately, optical image stabilization has trickled down from pro cams to the shake-prone pocket models. The cameras use motion sensors to detect any quiver and move a piece of the lens to compensate for it. I tested three in the most blur-inducing scenarios: in low light without a flash-the slow shutter speed gives you more time to twitch-and at full zoom, which magnifies shake.
An easy-to-install, gas-powered wheel turns any ordinary bicycle into a moped

Cycle your way out of traffic jams and high fuel costs-without breaking a sweat. Simply slide a canister of gasoline into your water-bottle holder, clip a throttle to your handlebars, and swap your front wheel for the Wheel, designed by Denver-based RevoPower (revopower.com). The Wheel's hub holds a 23cc, two-stroke internal combustion engine and a superthin gear train; less than three inches thick, it all fits between the prongs of your bike's front fork.
Surf the Web from the hammock out back (or the park down the block) with this solar-powered Wi-Fi extender

The promise of Wi-Fi is freedom-the ability to bring your laptop or PDA away from the anchor that is your desk and into your life. With most wireless routers, however, your life had better stop at around 300 feet, and forget about heading outside. Between the noise generated by other local wireless devices and physical obstacles like furniture and walls, chances are your Wi-Fi signal is little more than a whisper by the time it hits your backyard. So I built a box that can pick up that signal and boost it another 200 to 300 feet.
Learn to power small networked devices (like security cameras) with an Ethernet cable
By Paul WallichPosted 03.10.2006 at 2:00 am 1 Comment
Quick, how many cables go into the back of a wireless (a.k.a. Wi-Fi or 802.11) netcam? That would be one: a power cord.
How many cables go into the back of a wired netcam, which hooks directly into your ethernet? Also one, if you´re using PoE (power over ethernet). PoE takes advantage of the fact that only two of the four twisted pairs of wire (connected to pins 1/2 and 3/6) in a standard Cat5 ethernet cable carry signals. The other four wires are available to deliver power to your camera or whatever other AC-powered device you have on the network.
Turn a backpack into a portable, solar-powered Wi-Fi hotspot, and share a high-speed connection anywhere

I love the fact that more and more devices are sporting built-in Wi-Fi—the Sony PSP, smartphones, even Kodak’s EasyShare-One digital camera. The lone hitch: Wi-Fi is useless without a hotspot. Sure, thousands of spots are available, but few are free, and coverage is far from ubiquitous. What if you could marry the short-range power of Wi-Fi with the huge coverage areas of high-speed cellular services such as EV-DO to create a portable hotspot? You could use any Wi-Fi-enabled gadget anywhere you’ve got a cell signal.
