Somewhere along Brindcliff Edge Road in Sheffield, you can still see this wonderful infrastructural relic:
That’s a sewer-gas destructor lamp, of which there are maybe a dozen or so remaining in the city, though only a very few of them are a) undamaged, and b) still lit. Destructor lamps took a tricky infrastructural problem (the way in which noxious gases would accumulate in sewer sections near the top of hills) and solved it in a way that had a useful function (mixing said sewer gas with town-gas and burning it to light a street). I have a particular soft spot for this one because of the way it has been incorporated into the wall.
From a review at the Los Angeles Review of Books:
“Zielinski argues that what he calls “media” (a dense composite notion encompassing both discourse and its material supports) has vanished from the horizon because it is now ubiquitous.”
Obviously I need to read the whole book to make this claim more solidly, but nonetheless: this chimes with a chunk of my own infrastructural theory, where I claim that what we think of as “media” – which are themselves highly complex and increasingly emergent socio-technical systems – flow over and through a medium-of-media, a metamedium. That metamedium is the tangle of infrastructural socio-technical systems to which I refer as “the metasystem”, which has also been pulling a very effective disappearing trick over the last century or so.
Indeed, these two systems are effectively the public and private faces of a single coin. The metasystem is the screen upon which the Spectacle is projected; it is the conceptual veil which allows the enduring Western fiction of the social/natural dichotomy to persist, the discursive prestidigitation which distracts us from the (spatially) distant consequences of our technologically mediated consumption.
