I know its minimal, I'm not saying it's a concern, I'm just saying if we are harvesting it, doesn't that mean it's pulling us closer to it? It's not magically free energy (in the physics sense), so what else could it be other than converting the potential gravitational energy between the earth and moon into something else?
see my other reply in this thread
basically it doesn't move the moon closer, but it makes the Earth rotate slower. that's where the energy comes from.
basically the tides transfer angular momentum from the Earth to the moon.
