We live in a time when we were able to see many inventions that no one expected, and if this happens it will be very wonderful, but I will not be able to believe it until I see it with my own eyes.
But is it a perpetual machine still not possible in our current understanding of physics? I didn't study physics but used to read a lot in high school. So the energy involved can't be created out of nothing. It has to be there in advanced and can be harvested. But once the energy is taken out it shouldn't be working anymore. Or am I wrong? And you would need a lot of more power than the energy needed to create all of the parts of the machine.
