Japanese researchers developed a system that converts electricity into short-range radio waves to power an electric car. The system features high-speed inverters that deliver the radio waves to the car using a metal track embedded below the road surface. The car then conducts electricity from the RF signal using steel belts inside its tires.
The system could lead to a way to continuously power electric vehicles while driving, reducing battery size, and eliminating the need for charging stations. Additional developments would need to be required to make the system suitable for public use.
