> fiddling with information _as such_ and in theory doesn't use up any energy.

that's not true at all. Any time you destroy information (for example an and gate can destroy information) you use energy.

Chances are you know more about this than I do, and I'd be interested to learn more.

If you're willing to explain, I wonder how an AND gate destroys information. Certainly the output of a 2-input AND gate carries less information than both inputs together. But unless the gate is destroying the input signals, which it isn't, I don't see how infomation is being destroyed.
