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 That level of excitement sense entirely reasonable to me.
When my mother was small, she thought post boxes did something similar. She was deeply disappointed to discover that they don't!
