Unfortunately for you budding energy stars out there, the Pentagon's latest contest is over, so you've no choice here but to grit your teeth and applaud both DuPont and Germany's Smart Fuel Cell. Out of the 170 teams vying for the $1 million prize, these two managed to impress the most; the winning gizmo was the M-25 portable power system, which is already being sold to the US Army for "limited use in the field." Contestants were tasked with creating a new wearable power solution to juice up energy-hungry military gear (GPS units, night-vision goggles, head-mounted PMPs, etc.) without weighing soldiers down, and the winning device combined "DuPont's direct-methanol fuel cell technology with SFC's fuel cell and battery system." Yeah, we're totally expecting a PSP / DS compatible version of this before the holidays.

We're all about giving golf claps where they're due, and a healthy round is certainly in order for Mr. Brian Schulkin. The doctoral student in physics developed a breakthrough terahertz imaging device, dubbed a T-ray, that has already demonstrated its ability to "detect cracks in space shuttle foam, image tumors in breast tissue, and spot counterfeit watermarks on paper currency." The Mini-Z marks the first time such a powerful device has become portable in nature, weighing just five pounds and taking up about as much space as your average laptop. Taking home the first Lemelson-Rensselaer Student Prize ($30,000), Schulkin explained that this device didn't pose the same health risks as typical X-rays, and unlike ultrasound, terahertz waves can provide images and spectroscopic information without contacting an object. As expected, the patent-pending technology is already up for licensing, and has already received quite a bit of fanfare and commercial interest from larger companies. So while you may never personally encounter Brian's earth-shattering invention, we're fairly sure this young lad's working days are already drawing nigh if he so chooses.

It seems that automated floor-suckers are getting all the attention of late, as we've had users parading their Roombas around with all sorts of unorthodox methods, teaching them to bust a move, and now how to pose for the cameras. While already recognized in one Tokyo ceremony, the Fuji Heavy Industries and Sumitomo-created vacuum has officially taken the gold in the Robot of the Year competition hosted by the Japanese Ministry of Economy, Trade, and Industry. Due to its purported ability to replace "two live human beings" and clean out an area of "3,000 square meters in four hours on a single charge," the jumbo-sized Roomba wannabe can help those towering skyscrapers stay clean in a bustling world. Additionally, it can maneuver up and down floors, in and out of elevators, and around crowded workspaces with ease, but we're not exactly sure how many decibels of noise this thing cranks out while taking care of business. Nevertheless, the co-founders are selling the device for a whopping ¥20 million ($168, 011), but still claim that it will more than pay for itself after a decade or so -- you know, since it doesn't beg for health insurance or anything.

We totally heart DARPA (the folks who brought you the internet!), given all the sweet research that it funds. As such, our hearts sunk when Congress dropped the prize for DARPA'S 2007 Grand Challenge to nil back in October. But the Grand Challenge has just gotten a little sweeter, since Congress has since reinstated the prize money to $3.5 million, split three ways, (including amongst the Team B competitors): the winning team will get $2 million, the second place $1 million, and third place a cool half million clams, or bones, or whatever you call them. As you probably know, the 2007 Grand Challenge will be a 60-mile urban course, which means that the cars will have to navigate themselves through an unnamed city (or section of a city) somewhere in the Western US. Of course, this prize money isn't going to do much for offsetting the cost of such a large project, but it'll surely buy a lot of champagne at the victory party. [Warning: PDF link]
