Are solar ovens useful?

Solar cooking can help them to keep more food and improve their nutrition . Smoky cooking fires irritate lungs and eyes and can cause diseases. ... With good sunlight, solar cookers can be used to cook food or pasteurize water during emergencies when other fuels and power sources may not be available.

How do solar ovens heat up?

Instead of converting solar energy to electricity, solar ovens trap light particles, called photons, to generate heat . ... Once the cooking pot becomes warmer than the surrounding air, the heat attempts to escape to a cooler space. However, since it cannot break through the glass barrier, it remains trapped inside.

What is the conclusion of solar cooker?
