This is a leftover from a years-ago student project I supervised related to building a solar concentrater. It's a 5.4 x 4.5in (140 x 115 mm) slab of Alu. roughly 5mm thick, topped with 26 hollow short brass tube segments designed to generate turbulent wakes when air flows over them. Weight is 5-6 oz (~150g).
PM me if interested - domestic (U.S.) addresses get preference. |
