Let me get this out of the way: I am not formally educated in this specific area of physics.
Let’s also get this straight: By spending energy to remove and discard energy (AKA a refrigerator or a house), we are doubly shooting ourselves.
We turn energy into heat all the time, why don’t/can’t we turn heat into energy?
HIVAC systems move hot air out and discard it and move cold air in. Why not have these units move the hot air out and store it in an apparatus designed to suck the molecular kinetic energy out of the air and store it?
Story: I live in South Florida. My AC broke… it’s summer. It’s hot as hell. The thermometer in the house read 90 degrees. My brother has a house in Michigan with same exact structural dimensions. His AC is broken. His thermometer reads 72 degrees. Wouldn’t it be safe to say I have a ton of energy in my air compared to his air. Can’t I take that energy and power my house? Are you guys getting the picture?
I know from deductive reasoning that this is difficult to do, but why? It is so simple in theory…
Drop a rubber ball. Come back in a minute, it’s resting on the ground. Why can’t I take the heat that this process produced and make the ball bounce back up? I’m in theory land here folks, work with me!
If heat is simply kinetic energy at the molecular level, then why can’t we take heat and produce energy at our “macromolecular” level?
