Cook for free

A $6 solar cooker made from cardboard can not only cook food but also sterilize water set to help three billion people reduce their greenhouse gas emissions. The Kenya-based Norwegian creator of the cooker, Jon Bøhmer, has been awarded $75,000 to put the idea into production.

The cooker is made from two cardboard boxes, one inside the other, with either paper or straw insulation placed in between; an acrylic cover on top lets in and traps sunlight. Black paint on the inner box, and silver foil on the outer one, help concentrate the heat. The trapped rays make the inside hot enough to cook casseroles, bake bread and boil water [CNN]. Covering the cooking pot with a transparent cover retains heat and water [BBC], and temperatures inside the pot can reach about 175 degrees Fahrenheit.

I have seen this as far back as when I was in 7th grade (somebody's science project)... I wonder why it was never more popular...
