For some things, it is OK. It is not the only one, only the best marketed
one.

The original design and purpose required internal gensets. Keeping them
inside is still  important for a number of reasons. This is the Baltic, not
San Diego. Rain, fog, snow, etc. Both intake and exhaust are normally
coupled to the outside via boulder-blocked blasted tunnels, so the gas path
is not connected to the inside.

See what Mikael wrote.

I have been told by people who have been working with the construction of
this very site that it is an unusually dry cave. It is pretty high up by
Stockholm standards, which helps.
