Online Electric Vehicle (OLEV) is an electric vehicle
using electromagnetic induction
. On Tuesday, 9 March 2010 researchers from The Korea Advanced Institute of Science and Technology (KAIST) launched a public transport system using a "recharging road". Electric power strips have been buried 30 cm (12 in) deep under the road surface and connected to the national grid. Pick-up equipment underneath the vehicle then collects power through non-contact magnetic induction
which is used either to power the vehicle prime-mover or for battery charging. The demonstration system is a trackless train

Inductive coupling
In electrical engineering, two conductors are referred to as mutual-inductively coupled or magnetically coupled when they are configured such that change in current flow through one wire induces a voltage across the ends of the other wire through electromagnetic induction...

Trackless train
A trackless train is a road-going articulated vehicle used for the transport of passengers, comprising a driving vehicle pulling one or more carriages connected by drawbar couplings, in the manner of a road going railway train.-Terminology:Trackless train or land train...
