| Scientists invent wireless device that beams electricity across room | Friday, June 08, 2007 - 09:29 AM EDT | | "Scientists have sounded the death knell for the plug and power | lead," David Derbyshire reports for The Daily Mail. | | "In a breakthrough that sounds like something out of Star Trek, they | have discovered a way of 'beaming' power across a room into a light | bulb, mobile phone or laptop computer without wires or cables," | Derbyshire reports. "In the first successful trial of its kind, the | team was able to illuminate a 60-watt light bulb 7ft away." | | "The team from Massachusetts Institute of Technology, who call their | invention 'WiTricity', believe it could change the way we use | electricity and do away with the tangle of cables, plugs and chargers | that clutter modern homes," Derbyshire reports. "It could also allow | the use of laptops and mobile phones without batteries." | | Lead researcher, Dr. Marin Soljacic, designed a method "to fill a | room with a 'non-radiative' electromagnetic field," Derbyshire | reports. "Most objects in the room - such as people, desks and | carpets - would be unaffected by the electromagnetic field. But any | objects designed to resonate with the electromagnetic field would | absorb the energy." | | "The scientists say the technique works only over distances of up to | 9ft. However, they believe it could be used to charge up a battery | within a few yards of the power source connected to a receiving | coil," Derbyshire reports. "Placing one source in each room could | provide enough power for an entire house." | | "Professor Peter Fisher, another of the researchers, said: 'As long | as the laptop is in a room equipped with a source of wireless power, | it would charge automatically without having to be plugged in. In | fact, it would not even need a battery to operate inside such a | room.' The researchers believe there is little to worry about on | safety grounds, saying that magnetic fields interact weakly with | living organisms and are unlikely to have any serious side effects," | Derbyshire reports. | | For more information see the following web address: | | http://www.dailymail.co.uk/pages/live/articles/technology/ | technology.html?in_article_id=460602&in_page_id=1965 | | --- | [This E-mail scanned for viruses by Declude Virus on the server aea8.k12.ia.us] | | --- [This E-mail scanned for viruses by Declude Virus on the server aea8.k12.ia.us] --------------------------------------------------------- Archived messages from this list can be found at: http://www.mail-archive.com/info-tech@aea8.k12.ia.us/ ---------------------------------------------------------
