In my tour of the 2017 Solar Decathlon, Team Maryland was my favorite. Their project called reACT (ie. Resilient Adaptive Climate Technology) proved to me that a sustainable future needs to merge indigenous/cultural traditions along with modern technology. This is not just about energy either. Even though the architecture and engineering were exceptional in this design, the incorporation of cultural traditions gave the house much more impact than the rest of the entries at the Solar Decathlon.
During my tour of reACT, I spoke with some of the team and learned about the Native American philosophy called the "7th Generation Principle". This simply means that we should think about our future descendants 7 generations from now (or about 140 years) and honor them by leaving the world better.
