No
No, that would violate the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another. Therefore, it is not possible to build a machine that produces more energy than it takes in.
nobody built a time machine yet but nothing is impossible you could be the first to do so
no
So that farming could be easier and done by a machine.
A perpetual motion machine cannot be built because it is impossible to completely eliminate the energy losses that naturally occur in any physical system. These losses prevent the machine from continuously operating without an external source of energy.
A perpetual motion machine cannot be built because it would violate the laws of thermodynamics, specifically the first and second laws. The first law states that energy cannot be created or destroyed, only transferred or converted. The second law states that in any energy transfer or conversion, some energy is always lost as heat, making it impossible to achieve 100% energy efficiency in a machine.
A dam or a water wheel to produce electricity from the water flow. Hooweestik.
There is no answer to your question because a perpetual motion machine is impossible. If one could be built, its own motion would be considered work.
The man built a machine that could fold paper
No human has built a time machine, so a 9 year old would find it rather difficult.
It does have a grinder built in to the left side of the machine.
