Solar box cooker from SKGSangha

Solar box stoves are sturdier than the simpler solar reflector cookers. They have enhanced features like the hinged mirror which reflects light into the box, a black-coated inner compartment, and a double-paned glass top that absorbs head and retains it.

Solar box cooking uses no fuel at all and heats food hot enough to cook them well, though it takes longer than when burning fuel. But, no danger of burning the food, the cook, or the pot! And no smoke, and no cutting down trees.
