Wireless Power Transmission an Overview of Technological Advancements

In today’s world most of the developments would have been impossible without the existence of electricity. The main mode of transmission of this electrical energy available to all of us is through wires but efficiency is significantly reduced in power transmission through wires. Only 70% of the electrical energy can be transferred efficiently. Moreover it is always difficult to lay cables in remote area. All these factors have given rise to necessity of a concept where the losses are minimized and convenience of energy transfer is increased. The concept being wirelessly transmitting power i.e. Witricity. In this paper we have given an overview of the recent researches and advancement in the field of wireless transmission of electricity. Various methods of wireless power transfer such as laser beaming, microwave power transfer, solar and magnetic resonant induction coupling are explained. We have also discussed the future aspects of wireless power transmission and have stated its various advantages. This paper helps us in understanding thoroughly the alternative method of transmission of power.
