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 And when you back I need to introduce you to some cool, like-minded people from the cuckoo in UCL’s nest, the university within a university that is the Bartlett. We’ll get some data and dig. Maybe we should adopt a slogan “Dig we must for a better UCL”… (if you don’t know what I’m referring to, maybe David will get the reference…)
