3. Introduction
• Nikola Tesla was a Serbian-American
inventor, electrical as well as mechanical engineer..
• A.C. inventor worked with D.C. inventor .
• Wardenclyffe Tower (1901–1917), also known as
the Tesla Tower made by him for wireless
transmission.

10. Advantages
• Non-radiative energy transfer is safe for people and
animals.
• Wastage of power is less.
• Highly resonant strong coupling provides high
efficiency over distance.
• Does not interfere with radio waves

11. Disadvantages
• Wireless power transmission can be possible only
in few meters.
• Efficiency is only about 40%.
• Need for standardization and adaptation. So a little
overheating occurs because of different voltages.
• Refitting old equipment or purchasing new
equipment could become a very expensive
endeavor.
• Possibility of “energy theft”

12. Conclusion
• Think that the city will be covered with WPT hot
spots , just like Wireless Internet, there will be no
need of charging batteries, or carrying adapters all
around !
• If we apply this idea to the whole city, we might
not have to use any wired cable. Moreover, in the
future, it would save the material cost,
