That's very likely. Much of this depends on what exactly Glenn wants to fill
the dome with. If its gas then it will get tricky as the atmospheric pressures
would get huge with even small to moderate depths. Another potential would be
to adapt Laserlight's idea and go for a liquid form of the components so
pressure state isn't so much of a problem... though in reality its probably
still more efficient to develop a small respirator than build big domes of
whatever material.
