Road Wireless Power System
A new wireless power system could help people avoid the inconvenience of charging the electric cars and wait for about more than an hour to make use of it again. Researchers at Stanford University adapted a concept from quantum physics to produce a wireless charger that does something other wireless chargers cannot: automatically tune the frequency of the radio wave — the medium that transfers the power — to account for changes in the distance between the charging pad and the device. Although other wireless-charging devices, such as those for phones, already exist, the efficiency drops dramatically if the device is too close or too far away from the charger. This means a phone has to be placed on top of a charging pad to work best, and an electric car needs to be parked directly over a pad to recharge efficiently. With this new concept, roads could power electric cars as you drive and make it efficient to "drive and recharge" rather than the old way "recharge and drive".
