A homemade solar cooker is very easy to make!
It has an estimated two-year lifespan. In that time, it can save two tonnes of wood, as well as the carbon dioxide emissions that would have been released if this wood had been burned.
- Corrugated cardboard (carton board) — 0.9x1.2 meters
- Aluminium foil — 0.3x3 meters, cut into strips as needed
- Paintbrush (or other spreading device)
- Utility knife or similar cutting device
- Pencil, pen or other marking device
- Draw the pattern on the cardboard.
- Cut out the shape.
- Score the fold lines using a blunt edge, such as a spoon handle. Make straight folds by folding against a firm, straight edge.
- Using a paintbrush or other spreading device, spread the glue/water mixture on the dull side of the aluminium foil, and press the glued sheets of aluminium foil tightly and smoothly to the side that will be the inside of the cooker. A few wrinkles won’t hurt.
- Leave flat until dry. Trim any excess foil.
- Optional: Bind the edges neatly using strips of masking tape.
