Can solar energy be used for cooking?

Solar cooking does not require any electricity but uses solar thermal energy to cook the food. This means that you can use a solar oven anywhere that has lots of sun. Solar cookers are used to cook food and pasteurise water for safe drinking. They use a free, renewable energy source and do not pollute the environment.

Can a homemade solar cooker really cook food?

A solar cooker uses the energy of direct sunlight to heat, cook, bake or pasteurize food or drink. It only works when the sun shines, so solar cooking can never be a stand-alone technology.

about 200°F
The black surface transforms the light into heat which is then trapped in the upside-down glass bowl. Kind of like heat getting trapped in a car on a hot day. The solar oven cooks food slowly on a low heat over a long period of time. A solar oven can reach about 200°F on a sunny day.

Why solar cooking is not popular?
