It's worth pointing out that until the Eye's reappearance in Journey and the lesser reference in Hide, I think it was assumed (and stated on the BBC website?) that temporal rifts (like in Boom Town and Utopia) replaced the Eye of Harmony as the TARDIS needed to refuel on such rifts. Not sure if anything narratively supports this though.
