I was thinking the same thing, but was actually very optimistic of how high this thing could go given the rocket equation. Does someone know how much pressure you need to get to a height of X with a system like this? I'd say that given we have 10m fountains, it would be pretty all right. Another way to look at this, instead of the water escaping the hose of the firefighter on the street-level, you could steer the whole water column with this thing.
