1. I do not understand why you called it an electricity generator ? Where is the input energy comimg from?
2. If the magnet at the left side moving up is due to Buoyant, why it moving down at the right side?
If the system is symmetry, the physics should be the same.
3. Is there any [b]non viscous fluid[/b] in real life? Have you found one? Is this a "thought experiment"/device?
