It is obvious any work being done negates the possibility of being 100% alternating.

Stu, you can't just string a bunch of words together and hope that they make sense.
Tre' has already given several examples of work being done by alternating current. You can generate heat with AC or DC by passing current (AC or DC) through a resistor. How is the AC any different than DC? Mr. Ohm observed that a constant resistance in a circuit will drop the same voltage whether the current is alternating or direct. Isn't the current through a resistance "work" as you define it? Are you disputing Ohm's law?
I don't know why you keep saying that.
There's no DC driving an AC motor but yet the motor still spins and does work.

"Still Working the Problem"
key word is 100%. heat and work do NOT contribute to the return flow.
This is kind of an interesting paradox. Using the waterflow analogy, your statement makes sense. However, if you were to insert a resistor in the ground side of the circuit, and then if you were to measure the voltage drop across that resistor, you would find that the "current" (V divided by R) on the "ground" side is exactly the same as it is across the original load. This suggests that circuits are "the same", no matter where you place your measuring device, which suggests that there is no real difference between the ground side and the hot side, in terms of electron flow. Of course, another way to look at it would be to say that after adding the resistor, the "ground" side of the circuit consists of the connection between the newly installed resistor and the negative node of the circuit, but you can add an infinite number of resistors in series, and the current will always be the same.
