What of the lower gravity (mentioned in "Peter's Commentary" here
www.lunar-reclamation.org/lavatube_pix.htm)? Would the lower gravity cause
the gases that form in the lavatubes in the first place be able to escape
more readily than is the case on Earth (lower gravity and also no atmosphere
'outside')?
Would that cause structural problems (reducing the strength of the tubes)?
