Original Note:
Perpetual motion, or "free energy"--getting more energy out than put into a system--does not exist. The first and second laws of thermodynamics (energy cannot be created/destroyed and entropy) hold constant in the universe. See, e.g.; https://www.bbc.co.uk/programmes/b06c06nd https://medium.com/intuitive-physics/perpetual-motion-machines-why-they-dont-work-1e192d2c0f62 https://books.google.com/books?id=Dk-xS6nABrYC&q=%22perpetual+motion&pg=PA167#v=snippet&q=%22perpetual%20motion&f=false https://books.google.com/books?id=mpmLUjAVua4C&q=%22perpetual+motion&pg=PA58#v=snippet&q=%22perpetual%20motion&f=false Also mercury is highly toxic: https://www.epa.gov/mercury/health-effects-exposures-mercury#:~:text=Elemental%20(Metallic)%20Mercury,-Exposures%20to%20metallic&text=Metallic%20mercury%20mainly%20causes%20health,irritability%2C%20nervousness%2C%20excessive%20shyness)%3B
