A solar powered oven made up of two boxes and an acrylic cover won the FT Climate Change Challenge, which sought to find and publicize the most innovative and practical solution to climate change, according to an article that appeared on CNN.

Jon Bohmer made the oven from two cardboard boxes with one inside the other box. The inside box was painted black to capture and absorb heat and the outside box was wrapped in silver foil to help concentrate the heat. The clear acrylic cover allows sunlight throw and uses the heat to trap the rays inside the box, making the box hot enough to bake bread and boil water.

This ingenious solution helps solves the problem of deforestation because the oven requires no wood in order to create heat, so no need for firewood from nearby trees.

It can also help people living in third-world countries by creating an easy way to boil drinking water, thus preventing them from becoming sick by drinking contaminated water.
