Summary
Solar stoves are a cooking method using the sun's energy. Students learn about the design, making and use of solar stoves in Peru.
Why Solar Stoves
Solar stoves use the sun's heat energy. They can boil water in 10–15 minutes and are free to use, apart from the initial cost.
Making the Solar Stove
The solar stove is made from cardboard, aluminium foil and glass. Instructions explain how to build the stove and its lid.
Heat Loss and Efficiency
Heat loss in solar stoves happens through conduction, convection and radiation. Efficiency of solar stoves is between 20% and 50%.
Key terms
- Solar radiation
- The sun's energy that reaches the Earth.
- Conduction

- Convection
- Heat transfer through moving air.
- Radiation
- Heat transfer through electromagnetic waves.
- Emissivity
- The ability of a surface to emit heat radiation.
- Contact resistance
- The resistance to heat flow between two surfaces in contact.
