More than a century of technological developments have made a reality of Jules Verne's fantasy. Today, submarines large and small crisscross the deep ocean. But compared to the Nautilus, in one important respect, real-life subs are a bit of a disappointment: they don't have much of a view.
The big military submarines don't have any windows at all, and even a scientific mini-submersible, like the famous Alvin, has only tiny portholes.
But now Peter Robbins has decided that he will emulate Captain Nemo and build his very own deep-diving submarine with a view, one with a transparent pressure hull.
