Week 5

      This was a big week for our group. We started making the prototype and purchased more materials. The inner shell of the prototype was made in the machine shop at Drexel. The front and back sides will be attached with epoxy. Figures 5.1 and 5.2 show the inner shell of the prototype.

       This will be painted flat black in order to absorb the most heat. Insulation board and wood will be attached to the outside of the shell. They are being added to keep the heat in the box and support the thin metal. PVC pipe is going to attach to the front inside of the shell to collect the evaporated water. You can see the shell being epoxied below in Figure 5.3.
