How many functions can a roof provide?
shelter
fenestration
photovoltaic solar collection
domestic solar hot water
rain collection (roughly 14 gallons per square foot per year)
Direct and focus wind for power generation
The site for the farm lies near the crest of an escarpment: exposed to both prevailing Western winds and seasonal Chinook South winds. Since escarpments increase the pressure/velocity of wind near the crest, can we design a roof that will harmonize and enhance this natural phenomenon to increase the net power generating capacity of a wind turbine?
Possible limitations: The farm is sited on the approach to Pullman/Moscow regional airport. What is the maximum height we can build a wind turbine to?
And what about turbulence? Would a structure that focuses wind flow create so much disturbance that the funneling effect would be negated?
Could wind baffles made of piezoelectric material generate energy better than a conventional wind turbine?

A lot of your questions you bring up are very valid and it brings up the question, "will the structure/skin be self sustainable?". These all your cause.
I like the concepts of "multiple uses" for a given structural element. A designer once told me that from his experience, if a design element performed only one mission, it would never be sustainable, if two then you're headed in the right direction, but you would usually need 3 or more to really promote sustainability.
I wonder after reading your ideas, which are the most feasible. It might be good to see you develop a few ideas further.
