> 78 10 MW (13,000 hp) pumps that can pump up to 200 tons of water into the Edo River per second.[4] Wow, I hope the grid can handle the relatively sudden appearance of 780 MW of load. I assume they have some protocol in which why turn on one pump at a time and coordinate with the grid operators.
These enormous underground projects are so interesting. I've been following the Chicago Deep Tunnel project, which is nearing completion after half a century of work.[1] Because Chicago was built on swampland and next to the lake, rainwater used to be a huge problem because it didn't have anywhere to go when it rains, except into sewers - which used to be well under capacity for burst rainfall, which led to basement…
Just yesterday, a street downtown buckled from the pressure of stormwater running underneath it. 1. https://wgntv.com/2019/05/01/video-captures-street-buckle-in...

Massive side not - I have no idea why you guys insist on using football stadiums and football fields as a unit of measurement, what gives?
Just a handy visualization - easier to conceptualize than "12.9 billion gallons."
You mean 39600 acre-feet? :)

Dresden was also completely destroyed by Allies (for no good reason) and its firebombing caused between 200 000 and 300 000 victims (largely women, children and elderly). We don't talk about it much even though it was a crime against humanity as well. https://en.wikipedia.org/wiki/Bombing_of_Dresden_in_World_Wa...
From the Wikipedia article supplied: “Large variations in the claimed death toll have fuelled the controversy. In March 1945, the German government ordered its press to publish a falsified casualty figure of 200,000 for the Dresden raids, and death toll estimates as high as 500,000 have been given.[15][16][17] The city authorities at the time estimated up to 25,000 victims, a figure that subsequent investigations sup…

> The U.S. Eighth Air Force followed the next day with another 400 tons of bombs and carried out yet another raid by 210 bombers on February 15. It is thought that some 25,000–35,000 civilians died in Dresden in the air attacks, though some estimates are as high as 250,000, given the influx of undocumented refugees that had fled to Dresden from the Eastern Front. Most of the victims were women, children, and the elderly.

BTW they do offer tours of the pumping stations, but not the tunnels [2]

>twelve football stadiums stacked together I understand that football stadium play area is standard, but how do you measure height? Is it a foul to kick the ball too high in the air? The play area, I assume isn't limited vertically.
Tokyo was a city of canals before the Allies firebombed the city. Apparently the canals boiled due to the incendiaries used, so there was no escape from the fire during that tragic phase of life in the city. 100,000 deaths in one night is a statistic that few people think about, the Nazi death camps worked at a glacial pace in comparison, the craziness of WW1 campaigns gains a new perspective too, the bombing of Toky…
