VIMANAS were the “flying carpets” of ancient India. The Vaimanika Shastra is a text on aeronautics describing “chariots of the Gods”.

VIRMANA engine with Mercury… just a possibility of how it MIGHT work…. hmmm..

Meissner Effect experiement

Shown is a self-build YBaCuO superconductor (black disc), which is cooled by liquid nitrogen. The metallic cube is a strong magnet. At such low temperatures the superconductor has no resistance, thus there is a current induced into the superconductor by the magnet which again produces a magnetic field with equal but inverse strength. This magnet field causes then the magnet to hover over the superconducter
