      Great question! the perpetual motion machine has been the impossible ‘grail’ that has fascinated scientists throughout history (even Da Vinci had sketched out his ideas a perpetual motion machine)
      Of course, we know that its not possible as it goes against the laws of thermodynamics… but if I could invent one, I definitely would! In the mean time, a more realistic goal for scientists and engineers is to help society use less energy, more efficiently
