How to make an off-grid refrigerator
One of the challenges of living off-grid is how to keep food and drinks cold without relying on electricity. Fortunately, with some basic tools and materials, you can make your own off-grid refrigerator. Here's how to do it:
Materials you will need:
A large ceramic or terracotta pot
A smaller ceramic or terracotta pot that will fit inside the larger pot with space around it
Sand or sawdust
A piece of plexiglass or clear plastic
A towel or cloth
A thermometer
Instructions:
1. Choose your pots
Select a large ceramic or terracotta pot that is large enough to fit the smaller pot inside with space around it. The larger pot will serve as the outer shell of the refrigerator, while the smaller pot will hold your food.
2. Fill the gap
Fill the gap between the two pots with sand or sawdust, leaving enough space for air to circulate. This insulation will help keep your food cool.
3. Add a lid
Cover the top of the smaller pot with a piece of plexiglass or clear plastic. This will create a seal that will help keep the cool air inside. Place a towel or cloth on top of the plastic to help insulate and keep the heat out.
4. Add a thermometer
Insert a thermometer into the sand or sawdust insulation to monitor the temperature inside the refrigerator.
5. Keep it cool
To keep your off-grid refrigerator cool, you will need to add water to the sand or sawdust every day or two. As the water evaporates, it will create a cooling effect inside the refrigerator.
Tips:
Keep your off-grid refrigerator in a cool, shaded area to maximize its cooling ability.
Make sure to check the temperature inside the refrigerator regularly to ensure that it is staying at a safe temperature for your food.
You can also use a small solar-powered fan to circulate the air and improve cooling.
In conclusion, making your own off-grid refrigerator is a simple and sustainable solution for keeping your food cool. By using two ceramic or terracotta pots, sand or sawdust insulation, a piece of plexiglass, and a thermometer, you can create a reliable and eco-friendly refrigerator that doesn't require electricity. Give it a try and enjoy fresh, cool food even when living off the grid!
