My group was assigned the project of Renewable Insulation, and we chose to build a heat box. In order to build our heat box, we used a styrofoam cooler, alluminum foil, and reflective tape. We wrapped the cooler in the foil and sealed all the edges of the cooler with the tape in order to conserve as much heat in the box as possible. 

 

We started with simple sketches and ideas for the project and also had to do some preliminary calculations.
