Open Source Peltier Refrigerator

Introduction

• 4x less efficient than compression-based refrigerators, but may be worth it for reasons of higher simplicity or where DC only is available - [1]
• DOE publication evaluating refrigeration types - [2]
• This is made up for by using a chest-style refrigerator. How many times more efficient is a top opening vs front opening fridge?

• 10-20x - [3]
• 10x - [4]
