The Korea Advanced Institute of Science and Technology (KAIST) has developed an environmentally friendly public transport system that uses a “recharging road” to power up vehicles. Vehicles suck power magnetically from buried electric strips.
The system towing three buses, went into service at an amusement park in southern Seoul, where the mayor of Seoul and the president of KAIST joined other guests on a 2.2-kilometer (1.4-mile) ride around the zoo at Seoul Grand Park.
Named the Online Electric Vehicle (OLEV), the system requires a battery that is only one-fifth the size of conventional electric vehicles and so major recharging is not required. It also eliminates the use of overhead wires used to power conventional trams or trolley buses. After the success of the prototype, it is now going to be tried out on a bus route in the capital.
The vehicle uses pick-up equipment underneath it to collect power through non-contact magnetic charging from strips buried under the road surface. The power is then distributed either to drive the vehicle or for battery storage.
KAIST plans to use OLEVs to shuttle delegates at the G20 summit that Seoul will host in November.522415
