The Ultimate Aim of this project is Transmit the
Power By Wirelessmode.
Currently we want everything in compact &
consistent.
So there is anecessity toevery one to maintain the
chargingconditionvia air.
Here we are charging the batteries in wireless
modeto the instruments which ever is applicable based
onTESLA Theory

The resistance of the wire in the electrical grid
distribution system causes a loss of 26% to 30% of
the energy generated.Therefore, the loss implies that our present system
of electrical transmission is70% to 74% efficient.
In our country which is enormously occupied andconsume high megawatts of power there happen
frequent faults. 3

Wireless transmission of power is the process that
takes place in any system where electromagnetic
energy is transmitted from a power source to an
electrical loadwithout inter connection of wires. Thewireless energy transfer methods are important in
our present life.5

Nicola Tesla a great physician, concluded that
the earth is an electrical conductor, and that an
electric current can made to propagate
undiminished for distances of thousand miles.
Electrical energy can be economically
transmitted without wires to any terrestrial
distance

"Resonant inductive coupling" has key
suggestion in solving the main problem
associated with non-resonant inductive
coupling and electromagnetic radiation;
specifically, the dependence of efficiency on
transmission distance.

No conductor cost.
The efficiency of wireless transmission of energy
is in the range of 90% to 94%.
Rid the landscape of wires, cables and
transmission towers.
Great flexibility in power transmission.
Energy management thought the world.12
