The technology would be very familiar to anyone interested in flight
or aerospace

In fact, I heard a man on the talkback this morning who expanded
on simple gyros. You start with a gyro spun at high speed. The
container that the gyro is in is spun at high speed at 90 degrees
to the rotation of the inner gyro. Then the whole is spun at 90 degrees
to that (ie spinning in the X Y and Z axes), all in a vacuum to reduce
friction and power input. His claim (he says is backed and supported
by engineers world-wide) is that the end effect is levitation
