WiTricity wireless charging system ready for market

Gizmag has followed the development of the resonant wireless power transfer technology WiTricty since it was first theorized in 2007. Now it appears the technology is only one step away from being available to consumers with the developers seeing take-up by original equipment manufacturers (OEMs). The company has also displayed a wireless charging system designed for the iPhone 5 as proof of the capability and readiness of the technology for market.Read More

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

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

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

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.Read More

Wireless charging of electric buses to be put to real world test in Germany

Regional German transport operator Rhein-Neckar-Verkehr GmbH (RNV) is set to carry out a pilot project to test the viability of wireless inductive charging technology of electric buses. The trial will see two electric buses fitted with Canadian transportation manufacturer Bombardier's PRIMOVE inductive charging technology that will enable them to be recharged wirelessly as they let passengers on and off at bus stops along the inner city route 63 in Mannheim, Germany.
