This recipe for a simple, solar-powered oven is, quite literally, the hottest thing since sliced bread. Hot enough to cook casseroles, bake bread and boil water.
The cardboard box oven, aka “The Kyoto Box,” was designed by John Bohmer, one of over 300 participants in the FT Climate Change Challenge, a contest aimed at identifying and publicizing the most innovative and practical solution to climate change. As reported for CNN by Saeed Ahmed, Bohmer wasn’t attempting to make a world-changing scientific breakthrough when he entered the contest, but he also didn’t realize he would solve one of the world’s biggest problems with just $6 USD worth of simple materials.
While it may not be a day-to-day reality for us, it is estimated that about 3 billion people in developing countries cut down trees for firewood. This adds to global warming by way of deforestation. The solar-powered oven eliminates the need of rural communities to cut down trees to cook and most fundamentally, to boil water, which could potentially save millions of children who would otherwise drink contaminated water.
