Is it possible to have a unlimited powersuply made from water or electricity?

Question

If you were to put a system od pvc pipes in a full loop and added 2 pumps,would the water you put in turn the first pump wich would turn the seccond pump pumping the water back up the pie and repeat its self. same thing with electricty just with generators and some capcitors.

same thing as before but i ment to say put a gearbox that would make more power and last longer. What would happen if you combined both the electrical style and water...............?

Answer 1

Sorry mate, everyone's right, due to the law of conservation, by the time the water gets to the second pump, energy would have been lost through friction that when it gets back to the first machine the energy would be less than the original amount. So on and so forth until a total standstill...... : (

Answer 2

In theory the pumps could push the water, then the motion of the water could continue to carry itself forever. However, this ideal plan does not take into account the laws of thermodynamics, and things like friction. The water loses energy because of friction and so would slow down as it moved, and would eventually stop.

Answer 3

If you were to use this in a somewhat plausible industrial
application than you would save energy but not reach a perpetual state of regaining the energy. What you suggest is impossible due to energy losses.

Answer 4

All the frictional losses need to be accounted for and so, you need to pump in energy to keep the system going. So, not possible.

Answer 5

Do you think the world would be fighting over oil supplies if your plan was possible?

Answer 6

perpetual motion machines violate the 2nd law of thermodynamics.
