Wireless charging is becoming an increasingly common smartphone feature – but the Korea Advanced Institute of Science and Technology (KAIST) decided to think big about the relatively new technology’s potential. KAIST, in a partnership with the South Korean town of Gumi, has developed a pair of electric commuter buses that recharge wirelessly while driving over specially-equipped roads.
The Online Electric Vehicle (OLEV) motor coaches, which run round-trip journeys of 24 kilometers (15 miles) while completing their stops, are special because they can be charged while driving or stationary. Built with special electrical coils underneath their chassis, the buses collect energy while driving over power lines that are embedded in the asphalt – thus removing the necessity to plug in at a charging station from time to time. READ MORE
