Can water collection systems be built into the roof?
It is very simple to add rain collectin systems into any structure using the same two materials, plastic and foam, used in all other parts of the structure. Pipes and troughs are easy to construct and have undergone testing in rain collection. In addition, rain collection towers have been built completely out of the plastic used in the shell of the beams. A large tripod and suspended funnel can be cut from the sheets of plastic and used to collect large amounts of rain and dew.
