Week 5

This week, our group redesigned the whole structure of the air purification system. Instead of making the system a winding tube or a spiral, the system would be made of thin algae-filled sheets which were to be square with 50-centimeter sides, and with a 2-centimeter thickness. The design would contain fifteen or thirty plates, which would be separated by half inch gaps. We completely changed the design because if we were to use a 2-inch diameter tube to hold the membrane and algae, it would need to be 84 feet long to account for the surface area needed to purify the air for just one person. A winding or spiral tube would take up too much space in a house, and it would not be practical. We came up with the idea of sheets to maximize surface area. The structure is partially based on how bees kept by beekeepers build honeycombs on sheets; the sheets would be in a trough to hold them in place. We also began working on the CAD model of our new structure in Autodesk Fusion 360.
