could one possibly harvest the infinite power of the perpetuum mobile? I.e. is it possible to create one with liquid? Example: https://www.youtube.com/watch?v=Sv9JrnnZkLA
could you but a turbine under the fountain and harvest the momentum for energy?

No.

You don't have enough energy to form a constant flow, how would adding a turbine make that work any better?

Also if you discover infinite energy
feel free to conquer the universe for me

>momentum
Water doesn't flow down, it flows in all directions. The vacuum created in a straw only pushed the water upwards because the pressure of one atmosphere is pressing down on the surface of the fluid outside the straw.

Gravity doesn't even factor into the equation beyond creating atmospheric pressure, which we could replicate with inverse vacuums.

be wary of youtube videos featuring anything related to perpetual motion. They very often use tricks like strings or hidden pumps to fake the results

But then again Im not a Physics-mayor.
I know its not called momentum, but can someone confirm that Heron's Fountain does indeed work?
I just thought that if the weight (I know its not a scientific term) was the force pushing the water, you could harvest the movement that was created when it flew out of the pipe.

It does work, but it is not a perpetuum mobile.

Perpetual motion would be an interesting topic if we could make it work. It's not inherently /x/ aside from science having a law of conversation of matter and energy. Dismissing every possible thing as pseudoscience would kill the board's already slow activity. You obviously haven't been lurking here very long if you think these things can't be easily falsified.

There you go: we can't.

"The law that entropy always increases holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations — then so much the worse for Maxwell's equations. If it is found to be contradicted by observation — well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation."

It's fine in this case. I know what that anon means to say. In any other situation I'd agree with the quote, regardless of its source.
