Part 3/6:
The key component of Paul's setup is a collector made primarily from aluminum foil, which serves as the primary medium for energy collection. The foil is arranged in sheets that are cut into separate triangular sections, with their edges carefully folded together to create a stable, interconnected structure.
The foil sheets are doped with graphite—a material known for its conductive properties—and coated with enamel to provide durability and prevent oxidation. These coatings and dopings aim to enhance the collector's ability to harvest energy from ambient air.
