This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Heat pumps really are amazing tech. What if I tell you that this is also how your fridge works. Crazy, right?
They are also one of the few things that are more than 100% energy efficient.
300% to be exact. Because it uses some natural phenomena that just needs a little jump start and then can be maintained with little energy for massive air movement.
Ah... energy doesn't work that way. You can't have a perpetually endless cycle with 100% efficiency in real world.
It's called a CoP, Coefficient of Performance. It essentially is a factor of how much electricity you put in and how much cooling power comes out.
Cooling towers can have a CoP of 12 and beyond, whereas compression cooling usually lingers at around 3 to 3.5. so at a CoP of 3 for instance, you could put in 1 kW of electricity and get 3 kW of cooling power.
