3. a Protoss building which costs 100 minerals and supplies 8 psi and allows you to warp in other buildings. Protoss executors are frequently reminded to construct more of these, though in my experience the effort might be better spent reminding them to build additional photon cannons instead.

Here in Canada we refer to "traffic cones" as pylons. As someone living in London, Ontario, the first couple paragraphs of the OP was particularly funny to read; some sentences could be changed very minimally and apply all the same - "yet in a few places pylons are an intrinsic part of the landscape, like here along the edge of t̶h̶e̶ ̶R̶o̶y̶a̶l̶ ̶D̶o̶c̶k̶s̶ almost every road, due to construction."

My first reaction to the article was "We don't really use the word 'pylon' to describe these things, at least not here in the southern United States," though the term makes sense and doesn't sound strange to me at all. But now I'm struggling to thing of what term I personally would use, and honestly, I'm having difficulty. "electrical tower?" "transmission tower?"

"High tension line towers", or...hmm, I guess I don't know what the common usage would be in the U. S., southern or otherwise. And we live a block from a local Redmond, WA trail that follows the line of...high tension towers for miles in either direction.

But between my spouse and me, if we need to refer to them, we just call them "towers". "Pylons" are short little things, such as traffic cones (to borrow an example from another commenter).
