What makes me think of a Kraftwerk museum, if it doesn't exist yet (I don't think so) it would be rather interesting that one will be constructed.
Suppose someone out there did want to make a Kraftwerk museum. That would require the cooperation of Ralf and Florian. Do you think they'd return the calls or answer the letters? Do you think they'd allow any pre-Autobahn material to be displayed? How about anything about Wolfgang or Karl? You can see the kinds of issues one might run into. In any case, I don't think Kraftwerk is interested in becoming a relic of the past (though perhaps many people already see them this way). Kling Klang is as much of a "museum" as they need or want! This topic reminds me of the ridiculous "Euro-Kling Klang" at the end of Pascal Bussy's book. Fat chance! -Eric
