The History of Refrigeration

# Summary

In this episode, Josh and Chuck explore the surprisingly fascinating history of refrigeration, from ancient ice harvesting to modern mechanical cooling systems. They trace how humanity's obsession with cold drinks and preserved food—dating back thousands of years to Persian ice houses and ice picked from frozen lakes—evolved into game-changing technologies like refrigerated railroad cars and the modern "cold chain." The hosts dive into how artificial refrigeration transformed American society by making meat and fresh produce affordable and available year-round, though they also discuss the environmental costs of the chemicals used to keep our fridges cool.
