Think humankind discovering fire was revolutionary? How about a cardboard box that uses the sun’s rays to cook without burning firewood? That’s precisely what the Kyoto Box, a cardboard solar cooker, can do. Made out of basic materials that your 5th grade science experiment could have consisted of, the solar cooker offers a life-altering solution for thousands of people: the ability to cook and heat water. So how does it work? Inventor John Bohmer says the box uses “the greenhouse effect for something good.” It consists of two cardboard boxes, one which Bohmer’s own 5-year-old daughter helped him paint black, and another covered with tin foil to help concentrate the sun’s rays. A plexiglass cover is used to trap heat inside making it possible for the box to boil and bake, but not fry, so it is arguable that it is healthy as well.¬[sgl dagger] The Kyoto Box is already in production at a factory in Nairobi, and Bohmer hopes to offer a the box in a recycled plastic form in the future. The cost of the box will be a mere 5 euros.
