 The Ultimate Aim of this project is Transmit the Power By Wireless mode.  Currently we are want everything in compact & consistent.  So there is a necessity to every one to maintain the charging condition via air.  Here we are charging the batteries in wireless mode to the instruments which ever is applicable based on TESLA Theory EE F.R - W.T.E.T.T - B Batch 2

 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 is 70% to 74% efficient.  In our country which is enormously occupied and consume high megawatts of power there happen frequent faults.

 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” EE F.R - W.T.E.T.T - B Batch 9

 "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. EE F.R - W.T.E.T.T - B Batch 10

 Resonance causes objects to reverberate when energy of a certain frequency is applied.  Two copper coils are we used.  One coil, attached to a power source,  The other coil, attached to the device to be charged,  Both coils are tuned to the same EM frequency. EE F.R - W.T.E.T.T - B Batch 11

 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. EE F.R - W.T.E.T.T - B Batch 12

 Types of devices that can be charged wirelessly (handset, MP3, headset, etc) EE F.R - W.T.E.T.T - B Batch 13

 Africa is in need of power to run pumps to tap into the vast resources of water under the Sahara desert.  Rural areas in countries like India and China EE F.R - W.T.E.T.T - B Batch 14
