How would I light visible in a fog or a dust like scene ? I can't figure it
out.

See the docs concerning "scattering media", this should do exactly what
you want (i.e. make light beams visible in the atmosphere).
You'll also need to look at the example scenes included with POV
(in the interior\media\ section) and do some experimenting to find the
settings that satisfy you.
