They have many different systems and move the wheels to be considered under the earth, including induction, laser or microwave. Now researchers in Japan have studied a system that uses radio signals to drive an electric car.

The system of Masahiro Hanazawa Toyota Central R & D labs, and Takashi Ohira proposed Toyohashi University of Technology. This technology is in the highway underground to produce a strong radio frequency (RF) to drive the car to integrate.

Later, the car is a signal by a steel cable inside the tire is replaced, the system will change the shape of the vehicle on the radio frequency electrical energy into the electric motor running in the car.

The system it is expected that electric vehicles do not need to fear a battery in the middle of the journey. Therefore, the system automatically charges the battery of nature. Other effects, the battery is more compact, with less energy.

However, the RF system is still very implementation. But their hopes, this system is an alternative energy source is cheaper today.
