Testing different Peltier coolers by cooling/freezing water - Part 1 - Introduction

This is another video series, where I try to systematically test the Peltier devices I have. What I will do in this video is that I will use the 5 different Peltier devices that I used in my previous test series and I will cool down a known amount of water and a known amount of aluminium (holder for the water) inside a more-or-less well insulated box to exclude the majority of the heat loss. In this intro, I just talk about my ideas and the test setup. This video will be followed by 5 test videos and a final, conclusion video.
