Tesla Single Wire without flat pancake coil

Here I used two standard E coil transformer to replace the Tesla's pancake coil transformers. Waveform can be transfer as well but the efficiency is not measured yet. One note: the output voltage can never be higher than input voltage like in Tesla's pancake coil.

1. No spherical capacitor is needed as well.
2. Light up a LED in the open single wire.
3. No difference in clipping any polarity terminals on the single wire coil.
4. Touching the open coil will increase the waveform voltage.
5. Touching any terminal on the single wire, and input and output terminals will not affect the waveform.
6. Touching the open terminal of single wire coil and any terminal of input or output coil will affect the waveform voltage. (similar to 4 but less intensity.)
