Energy Experiments Between 2 Metal Poles

I just read this from wiki, though I need to read more. According to wikipedia, this form of zero point energy was first experimented and a flow or exchange of energy demonstrated flowing inbetween two metal points or poles. I don't know if this form of energy is strong enough to cause things that were happening at our house, but it's interesting that two metal points are required. According to the Casimir efffect, the experiment is done with a metal object at one point and then another metal objest at another point, and the energy exchange occurs in the middle. I observed a man with a "metal detector" at the back of our property, behind our house, and then another man taking something out of a metal pipe that was in the ground and in front of our house.

Experimental observations
A phenomenon that is commonly presented as evidence for the existence of zero-point energy in vacuum is the Casimir effect. This effect was proposed in 1948 by Dutch physicist Hendrik B. G. Casimir (Philips Research), who considered the quantized electromagnetic field between a pair of grounded, neutral metal plates. The vacuum energy contains contributions from all wavelengths, except those excluded by the spacing between plates. As the plates draw together, more wavelengths are excluded and the vacuum energy decreases. The decrease in energy means there must be a force doing work on the plates as they move. This force has been measured and found to be in good agreement with the theory. However, there is still some debate on whether vacuum energy explains the Casimir effect as the force can be explained equally well by a different theory involving charge-current interactions (the radiation-reaction picture), as argued by Robert Jaffe of MIT.

The experimentally measured Lamb shift has been argued to be, in part, a zero-point energy effect.[5]
