We could use them anywhere we wanted. We just had to dig a hole in the ground and set the funnel inside. You can leave the cooker in the ground and go do something else. Jones and Velasco said the benefits of using the sun's energy to cook food are many, especially for people in Central and South America. Another benefit is making it easier to pasteurize water.
Bolivia has one of the highest child mortality rates in South America because of contaminated water.
This method would make it more likely that people would pasteurize their drinking water. Jones also mentioned the solar cooker's ability to help preserve the environment. An estimated 3 billion people cook their food over fires. It's also estimated that two-thirds of the time you can cook with the sun instead of wood near the equator. Many women and children get sick from smoke inhalation because of the wood and other fuel sources used while they cook.
