Wireless charging technology coming in 2013

Intel could include wireless charging technology in select ultrabooks and smartphones beginning in the second half of 2013, according to a report from Digitimes.
It will use an ultrabook as the power source paired with related software and a transmitter to wirelessly charge a smartphone.
Samsung is also expected to launch a resonance wireless smartphone charger by 2013.
The report did not specify whether the charging will use the newer resonant inductive coupling system for longer range and higher efficiency, but it did say the phone did not have to be in a specific location, which suggests that the longer-range version will be used.

How much charge can be sent at one time? One of the biggest challenges for robots, is the power limitations. Tesla was building towers to transmit electricity. Maybe that type of system might be practical, especially in commercial applications.

“How much charge can be sent at one time?”: In the MIT study in Science magazine (DOI: 10.1126/science.1143254), researchers were able to transfer 60 watts with ~40% efficiency (24 watts received) over short distances (about 2 meters), which would allow for charging many batteries simultaneously for typical consumer devices (the charging ability in milliampere-hours for a given design and distance is limited mainly by the battery’s charging rate and number of batteries simultaneously charged). Tesla’s wireless power inventions were similar in some ways, but not practical.

Practical is putting it lightly! Can you imagine how beautiful our lands would become with the absence of electric wires?
