Take a metal can and cut it horizontally in half.
Place two metal sponges inside the bottom part. Then pour enough liquid alcohol over the sponges until they are thoroughly soaked.
This will be the combustion system.
Step 6: System Power On
Insert the can with the alcohol-soaked sponges through the square opening you cut in the front of the bucket.
Carefully light the alcohol using a match.
The generated heat will begin to rise and heat the stones, which will accumulate the temperature and release it gradually.
Functionality Test
As proof, you can place some sausages on the hot stones and observe how they cook thanks to the accumulated heat.
This demonstrates that stones act as efficient thermal accumulators.
How Does This System Work?
The principle is simple:
- The alcohol generates the flame.
- The perforations allow air to enter and exit.
- The stones absorb heat.
- The mesh holds the material.
- The bucket concentrates and directs the temperature.
It is a basic thermal storage system by combustion.
Tips and Recommendations
- Use it only outdoors or in very well ventilated spaces.
- Never use it in enclosed spaces without ventilation.
- Keep the system away from flammable materials.
- Do not leave the fire unattended.
- Use gloves and protection when cutting the bucket.
- Make sure the stones are completely dry before use.
- Always keep water or a fire extinguisher nearby for safety.

This homemade system demonstrates that it’s possible to generate heat using simple and readily available materials. However, when working with fire and fuels, safety must always be the top priority. Properly constructed and used responsibly, it can become a practical alternative for generating outdoor heat without relying on gas or electricity.
