The "Minimum" Solar Box Cooker
Solar ovens can cook food or pasteurize water using only the power of the sun. How does a solar oven work? The simple answer is that it is designed to absorb more heat than it releases.
The “Minimum” Solar Box Cooker is a simple cardboard box cooker that can be built in a short time for very little expense.
The designers of this cooker, named it the “Minimum Solar Box Cooker” because, at the time, it represented the simplest design they could devise. What they didn’t communicate with that name was that this is a full-power cooker that works very well, and is in no way minimum as far as its cooking power goes.

Simple as Flipping a Switch to Abundant Energy Supplies
In our modern day environment, flipping a switch to abundant energy supplies is usually an unconscious act with little awareness of the critical issues that lie behind it. But many of the world’s inhabitants do not have a switch to flip.
About half the inhabitants of the Earth cook over wood fires — 45% of the world’s wood is used as fuel. But there’s not enough to go round: some 2.4 billion people are now facing shortages of fuel wood.
Meanwhile deforestation helps cause climate change, floods and soil erosion, increasing environmental degradation, and increasing poverty and hunger.
Smoky Indoor Cooking Fire
Wood smoke from cooking fires is a major source of air-pollution and an outright killer: it causes respiratory infections which kill at least 5 million young children each year.
At the same time millions of people do not have access to clean drinking water, causing widespread disease, especially among children: the WHO says diseases spread through contaminated water cause 80% of the world’s illnesses.
There’s a simple answer to help ease some of these problems, that can save millions of trees, provide clean, safe drinking water, doesn’t pollute, and that costs very little – a cardboard box.

A Simple Box Solar Cooker
The Benefits of Solar Oven Cooking
Solar cooking is the simplest, safest, most convenient way to cook food without consuming fuels or heating up the kitchen.
Many people choose to solar cook for these reasons. But for hundreds of millions of people around the world who cook over fires fueled by wood or dung, and who walk for miles to collect wood or spend much of their meager incomes on fuel, solar cooking is more than a choice – it is a blessing.
How Do Solar Ovens Work?
There are a few different styles of solar ovens to choose from, but all function on the same basic principle by converting sunlight (solar energy) into heat. [click to continue…]
