We decided to build a solar cooker as a fun and educational science project. A solar cooker uses nothing but sunlight to prepare food – no fossil fuels, no wood. 🌱♻️ A small step for us, a meaningful contribution to a more sustainable future.
🎯 Goal:
To create a simple, low-cost solar cooker using common materials, test the concept, and gain hands-on experience with solar cooking.
🛠️ Our Approach:
📡 Reused a broken satellite dish as the reflector
🪞 Cut small mirror squares and glued them onto the dish
🛞 Used an old truck brake disc + welded steel frame for a stable base
⚙️ Implemented a zenith angle control mechanism for solar tracking
📊 Key Data:
🔲 Reflective surface: 0.79 m²
🔍 Concentration factor: ~130
🌡️ Test in March (Luxembourg): 170 °C reached
☀️ Test in July: 42 % efficiency achieved
💬 Conclusion:
A rewarding hands-on project that combines engineering, sustainability, and reuse. A great example of how simple ideas can drive real impact.
