Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to
an electrical load without a conductive physical connection. In this paper the technologies available for
Wireless Power Transmission (WPT) and its future possible advancements is being discussed to assume its
feasibility in actual practices.
In our present electricity system much of the power generated is wasted during transmission from power
plants to the consumers passing through cables, substations, etc. With WPT the need for inefficient and
costly, cables, towers, and substations will be eliminated & so will the power losses, finally reducing the
cost of energy. This is one such technology that can make the transmission system highly efficient &
economical. One mere demerit of WPT is that it develops reactive power at a small frequency that is very
biologically compatible and harmful to environment & living beings on over exposure.
