A couple months ago I blogged about the virtues of “solar cookers” — devices designed, chiefly for the developing world, to reduce the often-dangerous reliance on ever-dwindling firewood (and reduce carbon emissions a la fois). Now I see that one particularly ingenious cooker, cutely called the “Kyoto Box,” has won first prize in a “green” technology contest.
It is made from two cardboard boxes, which use reflective foil and black paint to maximise absorption of solar energy.
Covering the cooking pot with a transparent cover retains heat and water, and temperatures inside the pot can reach at least 80 [Celsius].
Perhaps by next year they’ll have come up with an even better “Copenhagen box.”
