Detailed descriptions of the construction of two aluminum downspout hot air solar collectors. The original was built by me, Scott Davis, and it works well, but then Scott Smith built bigger and added some really nice enhancements to collect a lot more solar heat! Scott is pulling 160F air from his down spout collector with lots of air flow and a better than 60% efficiency performance!
