Actually, they could possibly make 6 Volts. I don't believe you necessarily add the sum of all the voltages of each component battery to get the total output.
Ok, it can be done, but still goes back to why even bother when you can do it with less batteries. From what I and you saw, 6V lantern batteries use 4 longer version of D batteries that produce 1.5V. Only way to achieve 6V from 32 AA's is do a series-parallel wiring. You take 8 AA's and wire them together in parallel. This combines their storage power but produces the same 1.5V output voltage of a AA. Then making 4 groups of this setup, you then wire all 4 groups in series, thus making a 6V output cause in series you add the voltages.
So it can be done, but its not economical, and from what I've seen in the battery and in the video, its a flop not enough wiring and probably space.
Daniel, you're such a nerd 
can't help it I went to school for it.
