It's fascinating to hear about what's happening in Chicago versus New York versus Shanghai versus Paris because they will have a different system partly based on the specificity of the cities themselves and partly based on when the systems were built because things evolve.

I mean, it is amazing for tall buildings, but it's more amazing for entire cities, right? Which is what we do with, again, with Chicago, 12 pumps for all of Chicago. Now for a tall building, what happens is that you also have a pump in the bottom. So usually when you have a pump for an entire city, you want to have enough pressure. The pressure in the system is dictated by the fire department.

they want to make sure that when they connect their fire hose to the hydrant, they can put out a fire. And so that's why usually that pressure is about enough for that water to go up to a five or six-story building. So that's why five or six-story buildings usually don't have a pump in the basement, but tall buildings do.

You have two options, right? One is you look elsewhere, you see what they're doing and you reproduce something similar. And your second option is you see what you have and you try to do the best with what you have. So in the case of telecommunication, one of the things they did is, well, we like fiber optic cables, so we have to lay fiber optic cables there.

And so they went to, in New York, for example, I think they went to a lot of the old Western Union pipes that were there for some cables, and they just replaced all the cables with fiber optics. But usually it's one of those things, you know, where...

Well, you'd assume that that would be the obvious thing that you do, right? But in my experience, usually they don't do that too much just because things evolve so fast. So especially I talk with a lot of people in the transit industry. And when you look at how they handle a system in New York, Boston, D.C., Chicago, often it's going to be pretty different.
