Image yourself in an airport and your laptop battery starts to die. Wouldn’t it be nice to be able to charge your battery using wireless technology? You bet it would. Intel thinks it may be possible with the new technology they are toying with. In a demonstration they were able to light a 60 watt bulb from several feet away from a power source, only losing 25% of the power during transmission.
According to Intel, electricity can be sent via a wireless transmission. In a statement made to the press, Intel said:
Building off work unveiled last year by Massachusetts Institute of Technology researchers, Intel Corp. on Thursday demonstrated how to make a 60-watt light bulb glow from an energy source 3 feet away. The Intel team did it with relatively high efficiency, losing only a quarter of the energy the researchers started with.
“That, to me, is the most striking part about it – transmitting 60 watts at 75 percent efficiency over several feet,” said Intel’s chief technology officer, Justin Rattner. “The power pack for your laptop isn’t that efficient.”
Wireless transmission of electricity makes use of some basic physics. Electric coils that resonate at the same frequency can transmit energy to each other at a distance.
But this technology has a long way to evolve before it becomes a commercial product. In both the MIT and the Intel work, researchers used charging coils far too large for wide-scale use.
This is amazing technology and wireless electricity could be in our future. It makes one wonder. Could a system be built powerful enough to charge electric cars? Only time will tell.
