    As seems to be the case each year, one or two stars show up to demonstrate new technology here at the All Things D 'Science Fair,' and it just so happens that a pair from the University of Pennsylvania are soaking up the limelight this go 'round. uBeam's the company, and based on what we saw at D9, we're guessing that you'll be hearing an awful lot more from the duo in the coming months. The company's mission is to provide wireless power -- hardly a new concept, but it's all sorts of refreshing to see what's often thought of as a pipe dream get an injection of reality. The outfit is literally comprised of two people for the moment, with the prototype shown here concocted just a few weeks ago. The goal? To get uBeam transmitters installed in as many locales as possible, and then to hit critical mass from a device standpoint. Imagine walking into a restaurant with uBeam transmitters in the ceiling, and watching your handset magically recharge as you await your appetizer. Granted, the outfit's a long way from that -- its first product will be a small charging puck that'll connect to a bevy of USB devices. That'll pair with an enterprise or consumer-level transmitter, a device that will ideally be situated in a ceiling. For now, things are strictly line-of-sight, but the shipping system will be able to detect a uBeam puck in the room and charge it if it's anywhere within a 20 to 30 foot radius. We're told that the consumer version will be suitable for piping power to just a handful of devices, whereas the enterprise build will be able to juice up an undisclosed amount more. Care to learn more? Head on past the break. %Gallery-124958%

  • Powercast and Microchip fire up interest at a distance with wireless power development kit

    We're sure if you asked Powercast nicely it'd tell you a whale of a tale, about how the "more than 100 companies" who allegedly signed up to develop products that seemingly pull energy from the ether materialized into this light-up Christmas tree. Still, we'd be happy to forgive and forget if meaningful products emerged instead, and that's why we're moderately happy the company's announced a nice big development kit. $1,250 buys your firm or deep-pocketed hobbyist the spread pictured above, with a wireless transmitter to throw three watts and a pair of receiver boards to catch them from over 40 feet away, plus a low-power development board from Microchip equipped with that company's proprietary short-range wireless protocols and ZigBee functionality. We can't wait to see what people build, but we won't be snapping one up ourselves -- we're still holding out for the firm to go open-source and build an Arduino version. PR after the break.

  • WiPower flees to 1974, returns with through-desk wireless charging system (video)

    Based on just how intimately we studied Chris Berman's hairdo from ESPN's 1979 launch, we're more than confident in saying that the video produced here to showcase a "new" wireless desk is most certainly a relic from yesteryear. WiPower -- a company that was trumpeting its wireless charging pad way back in '07 -- has purportedly joined up with Gill Industries in order to showcase the planet's first production through-desk, wireless charging system at NeoCon 2010. The solution would enable laptop users to plop their machine down anywhere on their desk (within the charging area, of course) and have it instantly charge, and if you play your cards right, doing so may open up a wormhole to the era of your choice. In all seriousness, we already saw a working demo of a similar solution at Qualcomm's Computex booth, so there's a better than average chance that this stuff is ready to ship right away. Trouble is, there's no official launch date for Gill's new family of energy-infused tables. Blast the from past is after the break... if you're prepared.

  • Nokia hopes to one-up Touchstone, harness wireless power for "ambient" phone charging

    Like a page torn right out of the government's top secret files on Nikola Tesla, a Nokia research team is working on a wireless energy harvesting mechanism, which sucks up all that cancer-giving RF floating through the air and turns it into electrical current. Their goal is about to capture about 50 milliwatts of power for "ambient charging" -- which would at least be enough to top off the battery while the phone is off. Unfortunately, right now their current prototypes are only pulling down 3 to 5 milliwatts, and many in the industry are convinced it can't be done (don't worry, Nokia, that's just The Man, keeping you down). To be honest, we're not totally sure were comfortable with the thought that there's enough RF floating around to make this even theoretically possible, but as we slowly come to grips with our own mortality, we imagine we'd gladly pay an extra $70 or so for the privilege of never having to charge our phone again. Nokia itself isn't over promising: they plan on supplementing this juice with solar power, and thinks it'll be three or four years until it makes its way into a handset -- probably around the time your existing iPhone contract dries up.[Thanks, CanisMinor]

  • Powercast looking to bring wireless power to reality

    We know, energy without wires has always seemed like one of those novel concepts that sounds terrific in theory, but remains a tad difficult to imagine hitting the commercial scene for some time to come. Apparently, all that is about to become nonsense, as a Pennsylvania-based startup is set to capture the wireless-loving hearts of, um, everyone when it tackles contactless power products. Powercast has already "signed nondisclosure agreements to develop products with more than 100 companies (Philips, for instance), including major manufacturers of cellphones, MP3 players, automotive parts, temperature sensors, hearing aids, and medical implants." The firm's radio-wave-receiving miracle device trumps existing attempts by "adjusting to variations in load and field strength while maintaining a constant DC voltage," essentially ensuring that only low wattages (read: the stuff that garners FCC admiration) are flung around. The system basically consists of two parts -- a wall-plug transmitter and a "dime-sized receiver" that handles the real magic -- and energy is instantly transmitted whenever that disc comes within a yard or so of its tag-team partner. Incredibly, the receiver only costs "about $5" to produce, yet the outfit has already secured upwards of $10 million in private funding, which translates into one less American that desperately needs to win the lottery. Get ready folks, if all goes well, Powercast will be shipping "many millions of units" by the end of 2008 -- and maybe even sooner.[Via TWW]
