A woman in Africa built a solar oven from cardboardIssuing time:2026-01-08 09:47 In Africa, a woman built a solar oven from layered cardboard and foil — now she cooks lunch daily without electricity. Her design is simple but powerful: flattened cardboard boxes shaped into a reflective funnel, lined with kitchen foil and black pots placed at the center. On sunny days, it gets hot enough to boil rice, stew vegetables, and bake flatbreads — all without a single watt of power.
Neighbors from her alley often bring ingredients or containers, turning her modest courtyard into a shared midday kitchen. Some days she feeds up to 15 people — mostly elders, kids, and passersby. What started as an experiment to save cooking fuel has become a community ritual. She learned the technique from a small sustainability workshop and tweaked the model using recycled glass and a blackened cookie tin for better heat retention. The solar oven sits on bricks, angled just right for the strongest midday rays. In areas where firewood is scarce or fuel is costly, her invention offers a hopeful shift — cleaner cooking, no smoke, and shared meals. Kids now say “it smells like sun food” when lunch is ready. It’s not just about the food — it’s about what one woman made possible with cardboard, sunlight, and care. Article from Fact Fuel
