Sony applies for wireless power patent, wants to daisy-chain your energy
As much as we're familiar with wireless power, we know developing a truly contact-free form of charging has a whole raft of extra challenges, such as getting into the sweet spot for power delivery and the potential traffic jam caused by throwing another device into the mix. Sony thinks it has these problems licked through a newly-published patent application. Its method uses location-finding to steer users until they're close enough for the wireless power source to reliably do its job. In some cases, it can use one mobile device to relay power to another, keeping everything fed even if the main power hub is tied up. Multiple power sources next to each other can go so far as to decide which of them should be the one to send power. The patent isn't a certain sign that your VAIO or Xperia is about to cut the cord altogether -- Sony first submitted this vision of the future in 2009. Even so, it gives us hope that our gadgets will one day start charging themselves instead of making us hunt down a wire or charging plate.
Sony dives into wireless power game, makes it way more interesting
We've been watching wireless power startups spin their wheels for years on end, and while we've netted a few contact-charging solutions along the way, there's still a dire need for bona fide wireless power. A most unlikely candidate has just shown up to deliver that very need, with Sony's wireless power supply system reportedly pushing some 60 watts of juice across 50 centimeters (nearly two feet) of crisp, cool air. Currently, the magnetic resonance setup is running at about 60 percent efficiency, but we're sure the engineers behind the breakthrough aren't satisfied yet. So, should we expect to see a prototype BRAVIA HDTV at CES 2010 that needs no AC cable to function? Please Sony, say yes. Say it emphatically. [Via Impress]
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]
