Is perpetual motion of water possible?

Is perpetual motion possible? According to Frey: No, but things can be engineered to approximate or mimic it. “The laws of physics indicate that perpetual motion would occur if there were no external unbalanced forces,” he says.

How does a perpetual motion machine work?

A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source. Thus, machines that extract energy from finite sources will not operate indefinitely, because they are driven by the energy stored in the source, which will eventually be exhausted.

Is a siphon a perpetual motion machine?

A siphon can run perpetually if the source is continuing to be supplied with water and the water is coursing downward in elevation. It is possible to draw water from a river with a siphon conduit at an elevation higher than the outlet.

Do overbalanced wheels work?

An overbalanced wheel is one form of device that has been frequently attempted in the quest for a perpetual machine. This is impossible as it violates the laws of thermodynamics. However, an unbalanced mass can respond to external energy inputs, which is therefore not the same as perpetual motion.

What is the self-flowing flask of Robert Boyle?

The self-flowing flask of Robert Boyle. This is a digression, which the reader may skip. Robert Boyle (1627–1691), discussed the “hydrostatic” paradox to reveal the misconception involved. His clever example was a “self-flowing” flask (Fig. 5).

How does the self-flowing flask fill itself up?

Boyle’s self-flowing flask, a perpetual motion machine, appears to fill itself through siphon action (“hydrostatic perpetual motion”) and involves the “hydrostatic paradox” [17] This is not possible in reality; a siphon requires its “output” to be lower than the “input”. I have seen this principle in action.

Why can’t I build a flask?

First, the flask is an imaginary device. It does not exist. If you try to build one, it doesn’t work right. Second, any device that is designed to run on and on using its own momentum only works if you don’t draw energy away from it. As soon as you draw energy away from it — by requiring it to do work — it quickly grinds to a halt.

Why does the flask not work because of high kinetic energy?

The fluid will stop flowing when it’s kinetic energy becomes zero due to the inevitable loss. The rate of slowing will be higher if you extract energy from the flowing fluid. In conclusion, the flask does not work because of high loss.
