WHAT IS WITRICITY ?
“The transfer of electricity from one place to other
without using wires ” is Known as Witricity.
BACKGROUND
• Nikola Tesla – The Genius
He did enlighten 200 lamps
at the distance of 40 km,
wirelessly.
• But only 15% of ...
Reborn of witricity
• In 2007,MIT powered 60
watt light bulb from
2mts(7fts) at 40%
efficiency
• Forgotten invention was

WORKING PRINCIPLE
Works under mutual induction
.
Types of wireless energy transfer
There are 3 major types of wireless energy
transfer:
• Short range : Inductive Coupling

How wireless power works
NEED OF WITRICITY
Cell phones, IPod, laptop computers are capable
of re-charging themselves without ever being
plugged in.

  3. 3. WHAT IS WITRICITY ? “The transfer of electricity from one place to other without using wires ” is Known as Witricity.
  4. 4. BACKGROUND • Nikola Tesla – The Genius He did enlighten 200 lamps at the distance of 40 km, wirelessly. • But only 15% of efficiency was achieved.
  5. 5. Reborn of witricity • In 2007,MIT powered 60 watt light bulb from 2mts(7fts) at 40% efficiency • Forgotten invention was reborn in 2007 • Prof. Soljacic – Another Genius MIT-IBM Collaboration
  6. 6. WORKING PRINCIPLE Works under mutual induction .
  7. 7. Types of wireless energy transfer There are 3 major types of wireless energy transfer: • Short range : Inductive Coupling • Medium range: Resonant Induction • Long range : Electromagnetic Wave power transfer
  8. 8. How wireless power works
  9. 9. NEED OF WITRICITY Cell phones, IPod, laptop computers are capable of re-charging themselves without ever being plugged in.
  10. 10. IS WITRICITY SECURE?  Principle is based on Magnetic Waves. The question is if Magnetic Waves Secure ? The answer is we all live in a globe that has already surrounded by magnetic waves. Yes it is secure
  11. 11. EASE OF WITRICITY
  12. 12. ADVANTAGES  Getting rid of great deal with cables.  Places where we cannot have physical cables.  Safe, fairly, efficient and good range.  Theoretically one stationary coil in a room could supply power to multiple devices at receiving coil.  Power can be delivered in any direction.
  13. 13. Obstructions  Walls and furniture can be penetrated through by Witricity.  Only obstructions are metal structures like metal doors and metal walls.
  14. 14. USAGE AREAS  ELECTRICAL CARS  MOBILE PHONES  COMPUTERS  TELEVISIONS  ANY ELECTRICAL CONSUMING DEVICE
  15. 15. DEMO • Sony demonstrated its wirelessly powered television.[2010 October] • Demonstration of Witricity on cellphone and LCD at the TED conference.
  16. 16. FUTURE WITRICITY  Think that the city will be covered with Witricity hot spots , just like Wireless Internet, there will be no need of charging batteries, or carrying adapters all around !
