    This is another one of those videos that spends a lot of time in lateral subjects without diving deeper in the main subject. I thought the idea that earth radiates energy made by biological processes fairly significant, and a far more interesting thought experiment to meditate on (Can we find aliens by looking at the thermal signature of exoplanets? Is there a methodology we can use to measure the efficiency of life?). Instead, it covers extremely basic principles of thermodynamics and heat pumps, which has been done to death in other videos.
