TUCSON (KVOA) - You've heard of solar panels, but have you heard of carboard solar ovens?
Hundreds of University of Arizona engineering students got together Wednesday for the Solar Oven Throw Down to cook homemade biscuits in their hand-crafted solar ovens.
According to the university, the ovens were crafted out of cardboard, duct tape and aluminum foil.
The first year engineering students spent several months applying thermodynamic and mathematical concepts to the construction of their ovens.
The Solar Oven Throw Down was just the first one of their student's first hands-on designs experiences in the engineering design program.
