In rural areas, storage of vegetables, milk, and other perishable food items is a problem, especially in the hot summer months. The bamboo iceless refrigerator is a low-cost device for storing food. It can be made easily by rural women out of commonly available materials.
- A cylindrical basket made of bamboo or slender sticks of wood
with an open weave
- A loose-fitting lid
- Jute cloth
- Metal or clay tray (circular or square)
- Stones or bricks.
Build the iceless refrigerator large enough to meet your family's requirements.
1 Cover the basket loosely with the jute cloth. Sew the jute cloth around the rim of the basket. The lower end of the cloth must hang loosely around the bottom, exceeding the length of the basket.
2 Arrange four or five bricks or stones in a circle. Place the metal or clay tray on top.
3 Place three to five stones (or bricks broken in half) in a circle inside the tray.
