It would take more energy to push the ball through the flap than what is created by the machine.MiRc34 said:^The energy of the next 5 balls that are still floating upwards maybe?
The one that GP posted should really fucking go on mythbusters.
You don't need the balls to be heavy. Just make sure the belt is really tightened on the pulleys.Fries said:you would need the balls to be heavy enough so they can bring the "belt" downwards and also heavy enough so they generate enough lift to get the ball on the bottom through the water flap and pull the balls through the water. imo it can't be done.
This is only true in a vacuum.Panki said:It's impossible, it'd be a Perpetuum Mobile, and one of the basic laws of physics is that a Perpetuum Mobile can not exist.
It is possible to create a machine which can fuel itself, but there is no way for it to be possible to run forever. To have that there would have to be an effeciency of 100%, which is theoretically impossible to achieve.Fries said:This is only true in a vacuum.Panki said:It's impossible, it'd be a Perpetuum Mobile, and one of the basic laws of physics is that a Perpetuum Mobile can not exist.
In our world, it is possible to utilize the surrounding forces in order to make a machine that can fuel itself.
But, my point doesn't matter in this case because this doesn't utilize the surrounding forces.
