Why do you ask? The phenomenon you see in this video of a gyro rising on its own is unheard of in the entire world and requires all of physics to be rewritten. Interestingly, in Experiment 3 I show that the spin speed is not affected as the gyro rises or even when manually twisted, and thus a simple example of "free energy" as the energy is not coming directly from the gyro (i.e. the aether exists): https://steemit.com/mesexperiments/@mes/mesexperiments-3-gyroscopes-exert-inertial-forces-with-zero-loss-of-spin-rate-freeenergy

I go over this in extensive detail in my game-changing #AntiGravity Part 6: https://mes.fm/antigravity-playlist

But for a practical proof of #FreeEnergy and its continual suppression, one must first discover the truth of the most important event in all of history: 9/11.... https://mes.fm/911truth-playlist
