Perhaps this detour link will open doors for you and other Pi innovators

My comment at the bottom of the linked article (if they don't delete it) 
conveys the Pi's importance for less environment destruction. People 
need to learn to live in nature, not consume it. Less cars, air travel, 
newsprint using the internet instead is a big environment issue right 
now. Kind of put up or shut up time for some politicians.

I have really enjoyed some YuTubes triggered by your links.
