Before 1914, cold drinks were deadly because ice was harvested from polluted water. Artificial ice production, pioneered by John Gorrie and perfected by James Harrison, made safe, clean ice widely available. Refrigeration then revolutionized food preservation and countless other industries.
- 🧊 John Gorrie's early artificial ice machine used compressed and expanded air, but was commercially unsuccessful and attacked by the natural ice industry.
- 🧊 James Harrison improved artificial ice production using a fluid that evaporated and condensed in a closed loop, creating a commercially viable refrigeration system.
- 🧊 Natural ice harvesting was dangerous and often involved ice contaminated with industrial waste and animal carcasses, leading to diseases like cholera and food poisoning.
- 🧊 The widespread adoption of home refrigerators after 1927 was faster than the motorcar replacing horse-drawn carts.
- 🧊 Refrigeration technology is crucial for modern medicine, enabling vaccines, blood storage, and advanced scientific equipment like MRIs and the Large Hadron Collider.
