"Zabaleen" is the Arabic term for those visionary and enterprising people whose culture revolves around recycling. The Zabaleen are experts at "transforming one man's garbage into another man's gold" and aspire toward a net zero-waste economy. Applied and supported this could lead to true energy independence, not only by radically reducing our demand for "raw materials" and hard to extract natural resources but by recycling other less obvious phenomena and materials that are now wasted.
My final purchase of essential portable technologies to bring to Nat Geo and thence to Africa and the Middle East, in addition to the foldable solar panel and the biogas generator conversion kit, is the lifesaver bottle which produces pure sterile water for pennies per liter. What water wars?
