The particular comment of interest;

@rickbailey7183 4 weeks ago Apparently there needs to be some type of carbon material (e.g. wood in this situation) inside the copper spiral, and the bottom end of the copper spiral needs to be grounded (stuck in the ground a foot or two). Theory:

The spiral form incites an interaction between the copper wire and the ether (acting as an antenna), modulated by the wood, and ultimately grounding the ether energy into the soil.

Both copper and carbon are diamagnetic, and it was this interaction between paramagnetism (granite in the past, aluminum and terra cotta in modern times) and diamagnetism (quartz in the past, copper and carbon in modern times) that increased the energy of the soil and subsequently the amount, size and quality of the produce.

This also inherently had a beneficial impact on human physiology and psychology.

This information has been lost (hidden) for centuries for the sake of profit.
