'Recharging road' becomes fuel for eco-friendly buses in South Korea

We have been witnesses to a variety of green energy mediums to power up vehicles, be it wind power, solar energy, human power or biofuels. But, here is something completely out-of-the-box. Research in South Korea unveiled an environmentally friendly public transport system that uses a “recharging road” to power up vehicles. The Korea Advanced Institute of Science and Technology (KAIST) has developed a system that lets a vehicle suck power magnetically from buried electric strips.

Duded the “Online Electric Vehicle (OLEV)”, the system towing three buses, went into service at an amusement park in southern Seoul. Seoul mayor Oh Se-Hoon and KAIST president Suh Nam-Pyo were among the guests who enjoyed a 2.2-kilometer (1.4-mile) ride on Tuesday around the zoo at Seoul Grand Park. The system requires a battery that is only one-fifth the size of conventional electric vehicles and eliminates the need for major recharging. It also prevents the use of overhead wires used to power conventional trams or trolley buses. After scrutinizing the success of the prototype, the state-funded institute would try it out on a bus route in the capital.

OLEV works by using 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 has has applied for more than 120 patents in connection with OLEV, which are said to be safe, clean and economical. Although the University of California (Berkeley) was the first to develop the technology, KAIST was the one to get substantial results. KAIST plans to use OLEVs to shuttle delegates at the G20 summit that Seoul will host in November.
