Perpetuum Gravity Wheel Watch how gravity makes free energy movement! can be used in real life!:) i used gravity 30 not real gravity of our world! to have a real gravity like must be around 85 ! but thats to much bouncy cause my wheels are not round enough! and construct 2 cannot use to many collision points! still pretty good i think i increased the weight of big wheel to 5 kg (density) and smaller to 2 kg (2 density) friction 1 and since they are made from iron in my head are not having any elasticity or angular damping! even if you add elasticity increase the friction or angular and linear damping still they will roll! because left side is always heavyer then right side that sits on the smaller rolls!
