For the final model, I used Bristol Vellum, copy paper, and foam core. The base is two foam core pieces representing the sidewalk of Acorn Alley. The intricate steel structure is represented by Bristol Vellum held by copy paper columns.
The original material was wire, but after many mistrials, the material was found to be unfit for the construction of the model. The scale was too small to display the intricacy of the design.
In this construction drawing, materiality studies are displayed. On the left, the steel groves in the two L shaped beams separate the glass and solar panels to prevent chemical reactions. In the center the construction and attaching of each L beam is shown, with rivets in opposite corners. On the right the joint of four L beams is shown.
Here are two cross sections, the top view, and joints of the petal, as well as the interior gathering spaces.
Section and Section Detail. All Solar energy is captured within tanks in the larger columns for use in colder weather.
