Obviously perpetual motion is impossible as far as we know.
But I'm curious to see if there are any machines that generate energy very efficiently but just can't quite achieve over-unity due to a subtle quirk in physics (e.g: Friction or some microscopic force / phenomena) that prevents it from doing so.
I'm not looking for things that preserve energy like a flywheel in a vacuum. The device actually has to generate / convert energy of some form to another efficiently.
I'm looking for interesting dead ends.

Not sure if there is a device that can reach that high of an efficiency, there are too many physical boundaries to overcome

There are none, PM is impossible even in theory because of time and entropy.

Space-time crystals are in perpetual motion but cannot produce work.

Closest you'll get is time crystals

Incorrect as usual.
Sun is practically giving up infinite energy. Only mathematician would call the Sun finite in energy.

Say, how many years have you scientist-guys observed the Sun? Oh, only 300 years? And what kind of analysis have you done on it? Oh, only spectrophotometry from far away. Aww, how cute that you make predictions about the future of the universe 5 billion years forwards when you can't even predict what weather is it tomorrow

People understand fusion anf we know sun is powered by it you brainlet.

>>8806821
Prove it atheist

>>8806821
Sure, I agree it derives some of its energy through fusion.

Cool. List some of the other mechanisms and provide discriminatory predictions for them.
