I have just discovered that those odd waste/recycling bins that are all over the oldest bits of Bergen, Norway, link to an UNDERGROUND PNEUMATIC WASTE TRANSPORT SYSTEM. The waste collects for a bit and then WHOOSH... it's off to the recycling centre. All underground. No bin lorries (garbage trucks), fewer road vehicles, less noise... amazing. @davidho says that my (considerable) excitement about this is entirely unreasonable. I disagree.

@helenczerski @davidho I UNDERSTAND YOUR EXCITMENT (because, as a #mindustry player, I've a fondness for complex routing systems). However, I must note this requires a certain investment : all roads have to be open for pipes to be installed. And, maybe, in crowded undergrounds (think about Paris, London), it may not be easy to have those pipes find ways. But in other cases, it's incredible !
