Millions of people around the world cook their food over a smoky fire every day. It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun. Solar cookers, or ovens, have been used for centuries.
Solar ovens consist of a system of reflectors and a cooking pot. The rest is up to your imagination! Once you have collected or bought your solar oven, you can use it to prepare hot meals in the backyard, at a campground or wherever your heart desires.
Of all theinventions that could benefit humankind, a reliable solar cooker remains one of the most necessary. Countless people across the developing world still cook their food by burning wood or even cow dung, causingbreathing problemsand severe pollution in some regions.
The searching for a practical solar cooker has gone on for decades and produced dozens of models. But none of them have caught on importantlyfor use in the developing world because they can’t store heat. Without the ability to store heat, a cooker cannot be used, for example, on cloudy days.
But now a group based at theNorwegian University of Science and Technology(NTNU) is reporting adiscoveryin solar cookers. They say it will lead to the production of practical solar cookers within a year and a half and it can store enough heat during a sunny day to work for an entire additional day, even if it is cloudy.
