[TheForge] Shop Air using Copper

[sos at frii.com]

I've never understood how this makes sense. It takes a *lot* of pipe to
get any significant volume.

30mm pipe gives you a bit less than 0.2 gallons per meter of length, if
you don't mind the units. How is this affordable compared to a 40 gallon
storage tank?
