    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
