Good point: You're not "making" "new energy" in the process of using nanotech devices. Also, shouldn't the over-all calculation take into account the heat "savings" we get from using more efficient industrial and technological process? Seems like reducing whatever current effect human technology has on the planet's heat budget would have to be offset against heat created by use of nanotech . . . of course, that's subject to the same idea contained in the first point, i.e. that the Earth's energy system has only one significant real input -- solar energy.
