I was in Basel, Switzerland to see a friend in July and I can't remember seeing any power lines. I'd say that city is about as opposite to Bangkok as there is with its modernity, cleanliness, lack of crime, and pleasant populace (and nearly everyone speaks English). I felt like I was in a movie the whole time, wondering when it would end. Yeah, it ended--when I flew back home to the states. However, the multiple trolleys downtown do connect to an elaborate network of crisscrossing thin power lines. They travel on meandering embedded rails and sort of interact with pedestrians and bicyclists. It feels weird when one creeps up beside you, and the operator merely nods to acknowledge that you can walk past. It's nothing like how it works in Boston--no horns. Now that's the way life should be. And I'm willing to bet that they are working on battery powered options for the future.
