2. WHAT & HOW ?
Wireless electricity :
Power transferring without using cables.
Tesla coil :
It is an electrical resonating transformer.
It consist of a tuned circuit (LC circuit).

3. DIFFERENT WAYS ?

4. FAR FIELD TRANSFER SYSTEM
Electromagnetic radiation:
Using microwaves and RF power
AC/DC to RF Transmitter
Geo-
synchronous
orbit
Receiver RF to AC/DC

5. LIMITATIONS - FFTS ?
 Security concerned
 Deployment cost
 High voltage & greater cooling system
