Technological advances in wireless power charging and transmission have shown great promise for enabling plug-free and, in many cases, contactless charging for a wide variety of devices and machinery. From simple inductive charging mechanisms that require a direct point of contact between charger (transmitter) and device (receiver), wireless power systems have evolved to the point of promising the ability to transmit dozens of watts over dozens of kilometers. According to a new report from Pike Research, the wireless power market will reach an inflection point when it crosses the $1 billion revenue mark in 2012, and by 2020 wireless power system revenues will exceed $11.8 billion worldwide.
Wheelock adds that the industry taking shape around wireless power includes major manufacturers like General Motors and General Electric, as well as startups such as WiTricity, Pure Energy Solutions, and Powermat. However, at the moment there are no clear leaders in terms of technologies or companies, no industry-wide specifications or standards for interoperability, and little agreement about the size of the market opportunity and the most promising areas for investment.“Applications for wireless power are diverse, ranging from mobile phones to electric vehicles to unmanned aircraft,” says Pike Research president Clint Wheelock. “And in the future, wireless transmission will have the capability of sending large amounts of power to remote locations.”
