Abstract
In the present paper the various technologies available so far for wireless transmission of electricity and theneed for a Wireless System of Energy Transmission is being discussed to find its possibility in actual practices, theiradvantages, disadvantages and economical consideration. Thispaper is mainly concentrated on :i) The most popular conceptknown as Tesla Theory,
ii) The microwave power transmission(MPT) called Solar power satellite, and
iii) The highly efficientfibre lasers for wireless power transmission.
Many concepts, research papers, patents are available on wireless transmission of electricity but the commercial technologies are yet to be materialized. The paper also discussesthe possible ways to get useful and practical results out of all research carried out so far elsewhere.Microwave ovenmagnetron with electronics to control the output power. The output microwave power ranges from 50 W to 200 W at 2.45 GHz. A coaxial cable connects the output of the microwave source to a coax-to-waveguide adapter. This adapter is connected to a waveguide ferrite circulator which protects the microwave source from reflected power. The circulator is
connected to a tuning waveguide section to match the waveguide impedance to the antenna input impedance. The slotted waveguide antenna consists of 8 waveguide
sections with 8 slots on each section. These 64 slots radiate the power uniformly through free space to the rectenna. The slotted waveguide antenna is ideal for power transmission because of its high aperture efficiency Key words – Wireless transmission, Tesla theory, Microwave power transmission, Fiber lasers, Collaborative research.
