Week 4

      The goal this week was to decide which materials we still needed to purchase in order to complete the construction of the box. We determined that an acrylic sheet will be used to let sunlight pass throw it and into the box. This sheet will be purchased online and will be attached to the top of our box. Hinges will be attached so that the acrylic can be lifted and the box can then be cleaned. Figure 4.1 (TAP) shows what the acrylic sheet will look like.

             A bucket will be attached to the box via a hose and fasteners to collect the clean water. Having a separate area for collection allows for more storage of dirty water and less contamination between clean and dirty water. An example of the connection between the bucket and hose can be seen below in Figure 4.2 (pragmaticproducts).The entire system will be sealed and pressurized in order to increase the evaporation rate of the water. All of the materials will be collected by next week and construction of the box is already in progress.
