Consumers are now one step closer to the elusive cable-free TV. Sony has recently showcased a working wireless power-feeding system. The prototype on demonstration was shown to be capable of wirelessly supplying up to 60W of electricity to a 22-inch TV, featuring an effective range and transmission efficiency of up to 80cm and 80 percent, respectively. To achieve this feat, the solution deploys a passive repeater device based on magnetic resonance technology to act as a bridge between a 40 x 40cm wireless transmitter and receiver. Sony has not indicated any firm rollout date, though it is planning to introduce this wireless power-feeding system to a diverse range of consumer products.

Judging from early impressions, this is indeed a promising technology that could revitalize the A/V industry together with the growing popularity of wireless HDMI. That said, there are two key issues to address. For starters, we doubt users would trade a power cord for three bulky boxes that occupy even more precious shelf space--integrating the receiver into the actual products may be a possible workaround. Then there is potential interference from the overly congested airway, with perhaps a detrimental effect on gadgets such as the hard drive in your laptop and video recorder.
