Don't wanna sidetrack into energy-only discussions, but the energy necessary for hydrogen to be taken from seawater can be generated by tidal/wind/solar energy typically associated with seaside locations. So potentially the model for positively net efficient "Refining"/extraction exists. Infrasturcture for distirbution and supply already exists in the form of retail locations already in place. Only new 'storage/pumping' units need be installed. A pittance for major oil companies to incur.
What is lacking is the motivation.
Also, as for 'film/celluloid' ceasing to exist. It is still the most efficient method for achiving images known to man. Nothing we know of for sure lasts as long. Movies being shot entirely through digital processes, are being archived on FILM so that the actual images still exist in an optical form. Much the same way that it is recommended you 'print out' your digital home photos so you have a 'hard copy' should the disc be lost or erased. So I don't see celluloid as an archival medium dissapearing in our lifetimes. (It's been around over a hundred years so far.)
Cheaper manufacturing/distribution methods for media acquisition/distribution usually translate to higer profits for the distributor, not lower costs for the consumer. Compare the net profrits for an old 'vinyl' album to a CD in music - and you see the retail cost never went down even though the manufacturing cost diminished exponetially. This, of course, is part of what led to pirating. But thats another thread.
