I have been to this place. It is limited viewing, requires a reservation & the slots run out practically in seconds. Tough for us residents to get it as well. My wife could snag it in her third try, as a late birthday trip last year. It is gargantuan & having massive holding capacity. To give semblance with something familiar, it was like standing in NY Grand Central station, except it was felt bigger, empty, damp &…

The Fens in East Anglia in the UK has a lot of interesting pumping tech. The latest can do 100m3/s (https://www.edie.net/st-germans-pumping-station-keeps-fens-f...). If all the pumps failed there would be hundreds of km2 underwater within days or weeks

Earlier quoted context omitted.

The most important word to know is 逃げろ. If you hear it, you will likely see others start running, and you should run in the same direction.

> 逃げろ "RUN!", correct?

If you hear that, it’s too late for you, I’m afraid.

It’s time to go when your guide says: “It’s inexcusable and I’m very sorry for the inconvenience, but the control room has informed me that we should make our way towards the emergency exit five minutes to the south west of the left of the 7-11. Thank you for your understanding and cooperation.”

It must be the lighting and colouration, as your first two photos actually look like CGI or some sort of painted art.

I had to dust off a useless memory, but it looks exactly like Doom2 Map06 with Quake2 lighting added by the source port Doom Legacy

In a similar vein is the surge shaft being built as part of the Snowy 2.0 scheme in Australia. 28 metres diameter and 263 metres deep. It absorbs the momentum of the surge of water when the downstream power station closes its valves.

> In addition to this underground chamber, there are two massive pumps on either sides, which divert the water from whichever river is surging to the other (Arakawa & Edogawa possibly).

You probably mean pumping stations right? Usually single pumps don’t have that kind of flow rate. Just a nit pick though, your comment was really interesting!
