Let's discuss about Peltier coolers #1 - Water pump analogy

In this video I try to clarify a few things about the Peltier coolers. I also try to draw an analogy between the Peltier coolers and the water pumps. They work with the same principle, only the transported medium (water vs. heat) is different. I am planning to make this into a series, so if there are new questions, ideas, I will try to condense them into a new video.
