Korean mass transit moving towards wireless power

The world is slowly making the switch over to electric power, and while some mass transit systems have been powered by electricity for a while, it’s usually delivered through overhead cables that connect to the buses and trains at all times. However, Korea is moving away from overhead cables in favor of wireless power to its mass transit vehicles.

…The technology uses inductive charging to wirelessly transmit electricity from the ground to coils underneath the floor of electric vehicles. The ground has embedded power cables that transmit electricity to the pick-up coils. So far during testing, engineers have recorded an 85% transmission efficiency with the cables and coils.

Wireless power? Cool!
