If the claims of levitation, ultrasonic resonance, and/or lingam electrical plasma stone masonry methods are valid; perhaps the necessary RPMs for core drilling

If the claims of levitation, ultrasonic resonance, and/or lingam electrical plasma stone masonry methods are valid; perhaps the necessary RPMs for core drilling are lower than 1000 RPM.
Given drilled cores of e.g. (limestone, granite,), which are heavy cylinders that roll, when was the wheel invented in that time and place?

> The plasma treatment showed a maximum of 65% and a minimum of 15% reduction in specific cutting energy and was regarded as being dependent on mainly the hardness and size of the samples [and the electrical conductivity of the stone]

Perhaps the redundant doors of the great pyramid were water locks rigged with ropes. There do appear to be inset places to place granite cores for rigging.
Ancient and modern stonemasonry skills; how many times have they been lost and why?
