Had an unexpected encounter with Andy Pag's Bio Truck Expedition bus in Pokhara's Fewa lakeside camping grounds. The expedition is traveling around the world in a recycled school bus engine runs on vegetable oil biofuel with very low carbon emission. It collects used vegetable oils from homes and restaurants along the way and features other interesting sustainable technologies as well.
I returned twice to the camping grounds to find the truck locked and empty. Hope to run into the expedition team next time before I leave Pokhara this week.
