- ceejay 10y agoDon't get me wrong. I agree with the laws of thermodynamics :) , but just like we exploit a "closed loop" / "seemingly perpetual" system between the moon and the oceans, or flowing rivers, couldn't there exist other "closed loop" systems? After all, on the scale of a human life that closed loop system (between moon and oceans) is, for all practical purposes, perpetual.
- cmdrfred 10y agoSure you can, get me a moon and I'll show you how.
- witty_username 10y agoYes, but where does the energy come from for your perpetual machine?
- pjc50 10y agoThe water cycle is not "perpetual": it depends on input from the sun. The tides are not "perpetual": they depend on gradually taking energy from the orbit of the moon.
