KAIST's wireless charging system can charge 40 smartphones simultaneously

Researchers at the Korea Advanced Institute of Science and Technology (KAIST), have developed a wireless charging system that can charge around 40 smart phones at a time, from a distance of 5 meters (16 ft). While we've examined numerous wireless charging systems, even one that transmits power to up to 9 m (30 ft), KAIST's prototype can power multiple devices within its range. It can deliver enough electrical juice, the scientists claim, to power many larger devices like fans, TVs and computers, simultaneously. Read More

If at first you don't succeed: Glowdeck makes a second bid for release

By - April 8, 2014 10 Pictures
Last August, Justin Kaufman hit Kickstarter to try and get his intriguing wireless phone charger and Bluetooth speaker system into the hands of mobile music lovers. Sadly, the campaign was not successful. But rather than give up, Glowdeck's creator went back to the drawing board and tweaked the design before trying again. A revamped device has hit the popular crowdfunding portal again, and this time managed to blow past its funding goal in just 3 days. So what's different this time around? Read More

New tech could beam power from roadside stations to passing electric cars

By - November 14, 2013 1 Picture
Among the concepts put forth for decreasing the range anxiety associated with electric cars, one is to embed electrical coils within the asphalt. This would allow vehicles to wirelessly draw power from the road as they traveled, although it would also involve having to tear up existing roads to install those coils. An alternative could be on its way, however. Scientists at North Carolina State University are developing a system in which power could be transmitted from stationary roadside stations to mobile receiver coils in cars passing by. Read More

Cota system transmits power wirelessly at up to 30 feet

By - September 29, 2013 9 Pictures
In 2008, Gartner Research released a report in which it identified the number one IT grand challenge as "Never having to manually recharge devices." Physicist Hatem Zeine has invented what he believes to be the answer to this challenge. The Cota wireless power transmission system uses intelligently steered phased array antennas to focus a beam of microwaves on a receiver module – and only on that module. The inherently safe technology can deliver electrical power up to 30 feet from a central transmitter without any line-of-sight requirement and without interfering with other devices. The system is projected to hit the market in 2015. Read More

Glowdeck portable speaker system does a wireless double act

By - August 6, 2013 9 Pictures
Smartphone users on the lookout for battery-powered wireless chargers, Bluetooth music players, and funky smart lights that bop to the beat will likely have to settle for a small collection of separates. There are devices that tick a couple of boxes, such as the Black Diamond III or TDK's Wireless Charging Speaker, but good luck finding one unit that does it all. If Justin Kaufman's new crowdfunding endeavor is successful, however, your quest might well be an easier one. The upper surface of his Glowdeck Bluetooth speaker system can charge the battery of any Qi-compatible device placed upon it using its own powerful battery or via a wall outlet, while the lights at the bottom flash to notify users of incoming calls or texts, or sync to the music being thrown out of the front-facing speakers.
