In air, they flow less nicely in the form of arcs, sparks, and lightning.

--- End quote ---

The amount of energy flow through air can be ignored in Derek's experiment due to super low potential 20V and large gap 1m between the two conductors.

--- End quote ---

Sun provides energy to earth through photons with most of the energy delivered in infrared but also what we call visible light and a bit of UV
With the photoelectric effect so photons will transfer their energy to electrons.

Are you aware of the fact that light is an electromagnetic wave? Just like radio waves.

--- End quote ---
This is interesting hypothesis, but it has nothing to do with reality, unless:

1) Classical Electrodynamics is off by huge amount at non-relativistic macroscopic scale (scale of the last Veritasium experiment).

or

2) Law of conservation of energy is broken

Proving any of these experimentally would earn a Nobel Prize

Yes visible light is part of the electromagnetic spectrum. Sun is not providing electrical energy directly we convert photons into electric current flow through different mechanisms.

Maybe thermal energy is easier to understand. You can transfer that through radiation (infrared photons) in all directions so not very effective is you want to transfer that to a particular object and then you have thermal conductors (it just happens to be that electrical conductors are also good thermal conductors) so if you want to transport thermal energy you will use a thermal conductor and energy will flow through that thermal conductor not around it.

Where do you see broken law of conservation of energy in any of my statements ?
And how what I said has nothing to do with reality when that is exactly what you see in reality including Derek's experiment.
