Now time has come to fly car in the air. Physicists have taken one step in that direction. They are working on technology that will wirelessly transfer electricity from road to electric car using magnetic fields to send the power from one place to other place and provide the cars with an unlimited range.
Today's most advanced electric car have a range of little more than 160km.The system is in development at Stanford University,California.It would allow vehicles to be charged while they are driven, with copper wire beneath the road surface transferring electricity to identical coil under the car.
Shanhui Fan, associate professor of electric engineering at Stanford is leading the research and said t his team has proved that physics works. In his system, an alternating current passes through copper coils in the road producing the oscillating the magnetic field. The coils under the car detect this field and convert tit back into electricity.
Other system has been developed also to transfer electricity to vehicles but only Fan's team said that it would allow transferring electricity to a range of long distance. So vehicle would have driven so accurately above the coils.
But "What we have not done is to build a road and test transferring power to electric car" said Fan.
