They're solid state, so maybe 100W input power per projector. <30kw total is my guess, which is at most a few homes worth of power, not a town.
Yeah, but they really went to town with these lasers.

A few modern solid state RGB projectors making the same amount of power would be far less maintenance intensive.
I'll admit I haven't owned a water-cooled ion laser before. What maintenance do they require? I wasn't aware of any.
