Decomposing our engineering designs

IMG_9295Today we tried to take some next steps on our invention. We had to split our inventions into four parts: What we are powering? What is our power source? How will we store our power? How will we connect everything? For our phantom jacket, we really want to have some cool lights. We were surprised how many batteries it took to light up a string a lights that we could sew into our jacket. We want to use rechargeable batters. We also want to power everything, maybe with wind, maybe with solar. We still have to do some more tests! ~ S, J & M.
