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:

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.

That efficiency metric doesn't really reflect what's going on. Of course moving stuff around is easier than heating it.
