would the universe be considered a perpetum mobile?
i think so then its not imposible
edit:
also if you compare a dinking bird with an steam engine youll see why the drinking bird is a perpetuum mobile of the second class which DECREASES the universe entropy
an steam engine from the transformtaion of hi pressure water with HIGH energy into steam at atmospheric pressure with LOW energy obtains WORK
a dinking bird from the transformation of low energy liquid into high energy vapour obtain WORK
natural perpetual inverse entropy
besides dont get us lost in semantics science sophisms, time travel and give a driniking bird to leonardo and ask him if its perepetumm motion or not
