Internal energy of a comoving volume increasing as space expands?

[QUOTE="PeterDonis, post: 6817071, member: 197831"] If you are asking about the "tethered body" thought experiment described in the paper, I'm not sure if the paper's analysis is correct. That doesn't mean it is not possible to extract energy in this way in a dark energy dominated universe; it is. I'm just not sure that the detailed calculation given in the paper of how much energy can be extracted is correct. I need to take more time to look at it. [/QUOTE]
