Wireless Transmission of Electricity – Development
Tanuj Kumar Mandal1
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, and iii) The highly efficient fibre 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 discusses the possible ways to get useful and practical results out of all research carried out so far elsewhere.
Key words – Wireless transmission, Tesla theory, Microwave power transmission, Fiber lasers, Collaborative research.
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

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 . The most popular concept known is Tesla Theory in which it was firmly
believed that Wardenclyffe (Fig.1) would permit wireless
transmission and reception across large distances with
negligible losses . In spite of this he had made numerous experiments of high quality to validate his claim of possibility of wireless transmission of electricity (Fig.2). But this was an unfortunate incidence that people of that century was not in a position to recognise his splendid work otherwise today we
may transmit electricity wirelessly and will convert our
mother earth a wonderful adobe full of electricity.

Tesla wanted to transmit electricity from this Tower to the whole globe without wires using the Ionosphere. The source of the transmitted electricity was to be the Niagara Falls power plant.
The modern ideas are dominated by microwave power
transmission (MPT, Figure 3) called Solar power satellite to be built in high earth orbit to collect sunlight and convert that energy into microwaves, then beamed to a very large antenna
on earth, the microwaves would be converted into
