What’s on the roof of your house? How about on the rooftop of the building where you work or go to school?
If you’re like me (and much of the world), your answer is “nothing”. Your rooftop is largely unutilized space. But what if your rooftop heated and cooled your house? What if it did that for free, and collected your water and produced healthy, organic food for you and your family? In Jordan, buildings are steadily adopting a simple greenhouse unit that can do all of that, and more.
