Andy Magee
9.
Problems solved
No Tangled Wires
No need for electrical sockets
Decreases energy loss during transmission

23.
Resonance in RIC
Coil provides the inductance
Capacitor is connected parallel to the coil
Energy shifts back and forth from magnetic and electrical field
Radiation loss will be negligible

24.
Near field Energy transfer
25.
Advantages of near field techniques
No Wires
No e-waste
No need for battery
Efficient energy transfer using RIC
Harmless and Low Maintenance Cost
26.
Disadvantages of near field techniques
Distance Constraint
Field Strength have to be under safety levels
Initial cost is high
In RIC, tuning is difficult
High Frequency signals must be high
27.
far field energy transfer
Radiative
Needs Line of Sight
Uses LASER of Microwave
Aims at high power transfer
Tesla Tower was built for this
28.
advantages of far field energy transfer
Efficient and Easy
No need for grids and substations
Low Maintenance Cost
Can reach remote areas
Effective when transmitting and receiving end are along a line of sigh
29.
Disadvantages of far field energy transfer
Radiative
Needs line of sight
Initial Cost is High
