What would it take to build a cryogenic cooler?

I'm sorry I didn't catch that. Yeah, you're probably right. I need to have a better understanding of the difference so that I won't confuse things.

Let me see if this is correct:
Temperature is what we use to measure how warm something is.
Heat is the ENERGY or (Thermal Energy) we're measuring that a objects mass contains, and what's required to change it's temperature. In other words, you have to remove a given amount of heat to change the temperature of a thing?

Correct me. I'll gladly accept it!

Lets replace thing with Energy.
