Ok, let's say your cave gets hot.....

What do you want to do? Cool it off, right?

How do you go about cooling it off? You remove the hot air, right?

Now, here's your multiple choice question.

Where do you remove the hot air to?

a) Use a fan to blow it out the window. (Window is screened, so no bugs to worry about.)

b) Use a fan to blow it into the rest of the dwelling through your open door.





Do the math.
