Wireless system recharges electric cars automatically

New Scientist : To make recharging an electric car more convenient, a company has developed a plug-free system. Introduced last week at the Plug-In 2010 conference in San Jose, California, Evatran’s Plugless Power system can be fitted to a garage floor, and all the user has to do is park the car over the charging station and it will be recharged automaticallyâmdash;if it needs it. A drawback to the wireless system is that it is only 90% as efficient as plug-in recharging systems.
