The Pot-in-Pot Cooler for Food Preservation
In hot climates without refrigeration, food spoilage is a significant problem. The Pot-in-Pot cooler, a simple evaporative cooling system, extends the shelf life of perishable goods.
The Challenge
Food Spoilage: High temperatures cause rapid deterioration of produce.
Economic Losses: Farmers and vendors lose income due to unsold spoiled goods.
Health Risks: Consumption of spoiled food leads to illnesses.
Lack of Refrigeration: Limited access to electricity and refrigeration technology.
The Solution with Analysis of the Falafel Features
Implementation of the Pot-in-Pot Cooling System
Simplicity: Uses two clay pots with wet sand in between to cool contents.
Affordability: Made from inexpensive, locally available materials.
Scalability: Easily taught and replicated in various regions.
Repeatability: Works effectively in any hot, dry climate.
Quick Implementation: Can be constructed rapidly with minimal skills.
Mass Impact: Addresses a common problem affecting many communities.
Implementation Approach
Design Dissemination: Shared instructions through demonstrations and guides.
Community Workshops: Trained individuals on construction and usage.
