Abstract: In the present paper the various technologies available so far for wireless transmission of electricity and the need for a Wireless System of Energy Transmission is being discussed to find its possibility in actual practices, their advantages, disadvantages and economical consideration. This paper is mainly concentrated on : i) The most popular concept known as Tesla Theory, ii) The microwave power transmission (MPT) called Solar power satellite, iii) The highly efficient fibre lasers for wireless power transmission and iv) a centralized solution for user interface. Many concepts, research papers, patents are available on wireless transmission of electricity but the commercial technologies are yet to be materialized. The paper also discusses the possible ways to get useful and practical results out of all research carried out so far elsewhere.

Keywords: Wireless transmission, Tesla theory, Microwave power transmission, Fiber lasers, Collaborative research.
