>>12967971What if there were some machine that could--let's think of something crazy here--compress, thereby heating it, expose it to large thermally conductive surface area thereby cooling it down and then decompressing that same exact amount of gas thereby cooling it down completely AND THEN HERE'S THE KICKER we have a box that's closed to the outside and that cooled fluid is exposed to the air inside the box so they exchange heat thereby cooling the air inside the box and heating the fluid and then we repeat the process! DUDE DO YOU THINK WE COULD DO THAT
