Hydropower Memes

Thermodynamics police, open up! This "infinite energy" scheme is basically the physics equivalent of trying to lift yourself up by your own bootstraps. The meme shows a perpetual motion machine that violates conservation of energy by creating an endless water cycle through portals, then harvesting the falling water's energy with a wheel generator. Here's the problem: energy can't be created or destroyed (First Law of Thermodynamics), and systems always lose energy to entropy (Second Law). Even if portal technology existed, you'd need more energy to maintain the portals than you'd get from the falling water. It's like trying to charge your phone by plugging it into itself. The troll face says it all - this is precisely the kind of "genius solution" that makes physicists wake up in cold sweats.
