Last time I heard of some weird results of spinning superconductors was from Podkletnov. He claimed to see gravity reduction of 2% above the superconductor.

I remember that.
I wonder if they tried spinning in both directions.
Be interesting if, instead of weighing more, it was pushing itself through gravity like a propeller through water and turning in the opposite direction would make it weigh less.
Read “Beyond Einsteins Unified Field” by John Brandenburg.
He explains how rotating electrical/magnetic fields yield something synonymous with anti-gravity.
We’ve had it for years.
