Yeah, this sounds suspiciously like a Niven idea. He's an enormously creative writer, and usually with a good hold on physics.
But I see the big problem with this generator as being that it would likely violate the laws of thermodynamics: Wouldn't the power it created be less than the power necessary for teleporting the matter to begin with?
Of course, it all depends on what we mean by "teleporting". We've got to very carefully define our terms. If we achieve teleportation by making a wormhole (which I leave for the engineers), then this might work. Hmm, wouldn't the higher wormhole be pulled towards the lower one due to gravity? Unless some solid structure could stabilize it (again, a mere engineering task), it would take energy to support it.
I do believe that such a device would eventually be possible, but that it wouldn't produce more energy than it used. I suspect the first aliens from another star system who visit us will attempt to sell us this "infinite energy system" for mining rights to the rest of our solar system, and then laugh their [what passes for asses] off.
