Wireless Transmission of Electricity – Development
and Possibility


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 oven
magnetron 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.


































I. INTRODUCTION
In our present electricity generation system we waste
more than half of its resources. Especially the transmission
and distribution losses are the main concern of the present
power technology. Much of this power is wasted during
transmission from power plant generators to the consumer.
The resistance of the wire used in the electrical grid distribution system causes a loss of 26-30% of the energy generated. This loss implies that our present system of electrical distribution is only 70-74% efficient. We have to
think of alternate state - of - art technology to transmit and
distribute the electricity. Now- a- days global scenario has been changed a lot and there are tremendous development in
every field. If we don’t keep pace with the development of new power technology we have to face a decreasing trend in the development of power sector. The transmission of power
without wires may be one noble alternative for electricity
transmission.
II. THE TECHNOLOGIES AVAILABLE
In this remarkable discovery of the "True Wireless" and
the principles upon which transmission and reception, even in the present day systems, are based, Dr. Nikola Tesla shows us
that he is indeed the "Father of the Wireless." The most wellknown and famous Wardenclyffe Tower (Tesla Tower) was
designed and constructed mainly for wireless transmission of
electrical power, rather than telegraphy [1]. The most popular
concept known is Tesla Theory in which it was firmly ...
