Quick Answer
To make a portable solar oven for hiking, gather a cardboard box, aluminum foil, plastic wrap, and tape, then follow a simple DIY process to create a reflective surface and trap heat.
Materials and Preparation
To start, select a sturdy cardboard box (at least 6 inches deep and 12 inches wide) that can withstand outdoor conditions. Cut a hole in the top and a flap to create a window for food placement. Cover the outside with aluminum foil, ensuring a smooth, even surface for maximum reflection.
Assembly and Insulation
Line the inside of the box with plastic wrap, securing it with tape to prevent air leaks. Cut a flap from the top for easy access to the oven. Create an insulating layer by placing a layer of cloth or newspaper at the bottom of the box, then cover it with the flap.
Final Touches and Testing
Seal any gaps with tape to prevent heat loss. Test the solar oven by placing it in direct sunlight and monitoring the temperature inside. Aim for temperatures above 150°F (65°C) to cook simple meals. To improve performance, adjust the oven’s angle and position to maximize sunlight exposure.
