Making the TC’s shorter it’s now possible to place the condenser on varying heights above the secondary coil. The electric field should be more powerful now in relation to the virtual ground.
The tested result is that efficiency augments to 70% with the virtual ground. However the efficiency with the SSW box reduces to 11%.
Rms power input TxTC = (10.5 – 0.3) * 0.707)e2/47 = 1.1W
Distance between TC 12 meter: Virtual earth
Rms power output RxTC =(8.8 – 0.3) * 0.707)e2/47 = 0.77W
Effciency =77/1.1 = 70%
Distance between TC 12 meter: SSW box
Rms power output RxTC =(3.7 – 0.3) * 0.707)e2/47 = 0.123W
Effciency =123/11 = 11.18%
