You simple get the ball spinning just a tad and then immediately begin slowly rotating the device in a precessional manner. It usually takes a little practice, as the precession rate must be just correct. When you get it just right the gyro begins to increase in speed. You can immediately tell because it requires a great deal of precessional force, hence the reason it's great exercise. After a minute or so one can get it rotating at a high rate. You'll hear it humming quite loud. Similarly, we can do the opposite. Once the gyro is spinning, we can remove such energy by performing the opposite action. :-) QM claims the electron has angular momentum. I know, I know, supposedly it's a quantum value, or so they believe. It would be an interesting experiment to see if energy could be extracted from a permanent magnet, as we know there are appreciable amount of unpaired aligned electron spins in such PM's. As to how fast the PM must be precessed is unknown. For all we know it could require speeds greater than any PM could handle. One thing for certain, a real gyroscope requires precise timing if you are going to remove its energy.
