Wireless power transfer (WPT) or wireless energy transmission is the transmission of electrical energy from a power source to an electrical load, such as an electrical power grid or a consuming device, without the use of discrete human-made conductors. Wireless power is a generic term that refers to a number of different power transmission technologies that use time-varying electric, magnetic, or electromagnetic fields. In wireless power transfer, a wireless transmitter connected to a power source conveys the field energy across an intervening space to one or more receivers, where it is converted back to an electrical current and then used. Wireless transmission is useful to power electrical devices in cases where interconnecting wires are inconvenient, hazardous, or are not possible. Industrial systems and medical devices can be made more reliable by eliminating trouble prone wiring and replaceable batteries. The technique exploits simple physics and can be used to charge a range of electronic devices over many meters. The system could replace the miles of expensive power cables and billions of disposable batteries. There is something like 40 billion disposable batteries built every year for power that is used within a few inches or feet of where there is very inexpensive power. If this technology is adopted in future it will make everyday products more convenient, reliable, and environmentally friendly. This paper includes the techniques of transmitting power without using wires with better efficiency, due to which it does not affect the environment surrounding.
