Reminds me of the April Fools' Day news article that NPR ran a few years back, purporting to report on an ambitious new project of the Library of Congress to reproduce all known sound files on wax cylinders - the rationale being that this is the most low-tech and therefor most perdurable medium for long range storage. No power is needed for playback, just a cranking arm!
Perhaps what we need is a method of storing digital files on a shellac disc?! They seem to last forever, barring disasters...
