So what about the Matrix, the "heart and soul of the Tardis" that downloaded into Idris? Or the Time Vortex that Rose and then the Ninth Doctor absorbed from the hatch in the Control Room?

It is implied on different episodes that both of these are power sources for the TARDIS. How are they connected to the Eye of Harmony?

As for the Rift, I thought this was considered an energy source, a place where the TARDIS could go to "recharge", so to speak but wasn't actually powering the TARDIS. A bad analogy might be that the Rift provided energy to the TARDIS like a gas station provides gas to enable cars to move. But gas isn't an engine, it's not the power source, it's just the fuel for the power source.

As for DWU authoritative sources, I'm not sure why the 1996 movie is any more or less authoritative that any other Doctor Who story. I don't think there has been a consistent answer and I was hoping one of the smart Wikia users here would have found a way to link all of these TARDIS power/energy elements together.
