* Gumi - OLEV-powered buses enter regular use in
Gumi,South Korea -Gizmag, by Ben Coxworth -August 5, 2013: -- The South Korean city of Gumi’s transit system will see the addition of two electric buses that draw their power from the road. It’s the latest step in the development of the Korea Advanced Institute of Science and Technology's (KAIST's) Online Electric Vehicle (OLEV) system, in which electric cables embedded in the asphalt provide power to vehicles traveling on its surface... The cables in the road produce magnetic fields, which receiving devices in the vehicles’ undersides pick up and convert into electricity. It can be a continuous process, or cables can be placed in separate locations along the road, providing ongoing top-ups to a relatively small battery within the vehicle. Typically, only about 5 to 15 percent of the road surface needs to be excavated for the embedding of the cables... The buses will run a 24-km (15-mile) round trip route in Gumi’s inner city between the train station and the In-dong district. They will maintain a 17-cm (6.7-in) gap between their underbodies and the asphalt the whole time, receiving 20 kHz and 100 kW (136 horsepower) of electricity at a maximum power transmission efficiency of 85 percent...
