"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.

20th Biogas system in Seattle
Now in Seattle building our 20th biogas system with Mike Rimoin, this one using the Solar CITIES HDPE tank as digestor but trying out a simple telescoping system for gas collection (much as we had planned for system 3 at Sekem farm in Egypt) and a solar heat exchanger to keep temperatures up in the tank.
