Like if we started utilising the energy produced from the tides on a mass global scale, whether that will have an effect in the moons gravitational pull? And eventually have our moon flying off into space or something?

like perpetual motion is not permited in science theory, but by saying the moon wont change while we draw energy off its flight, states it is perpetual.

The energy we could consume from the tides would be miniscule compared to it's effect on the moon....
As is currently happening, the lunar effect of tides on the Earth is slowing Earth's rotation, and our day is getting just a little longer. Likewise, the energy we're losing rotationally is being added to the lunar orbit, and the moon is slowly moving away from the Earth.
If we could completely stop tidal effects on Earth (That includes not only the rising/falling ocean tides, but the rising and falling tides on *land*), you'd essentially make the lunar orbit unchanging. But, you'd have to completely solidify the Earth - impossible, at least for now. And, eventually, the effect of our atmosphere on the moon would actually *slow* the moon, until it eventually would fall into the Earth.

Actually, the moon is already moving father away from us. On a related note, the tides seem to slow down the Earth's rotation.
I don't know if we will every be able to draw enough energy from the tides to affect noticably either the Earth or the Moon -- since we are small and the Earth is massive -- but if we did, that might actually be a good thing, since it might prevent the Earth's slowing down anymore than it is, or the moon's retreat from us.

No, harnessing the tides would not have an effect on the moon. Think of a magnet in your hand and a piece of iron on the floor. If you move the iron AWAY from the magnet, the magnet does not change.

Tidal energy is going to be dissipated whether or not we decide to harness it. We might as well use it, otherwise it simply gets wasted. That is, our use of tidal power really has extremely little effect on the gravity field that the moon experiences.
Yes, it slowly causes the moon's orbit to decay, but it is extremely gradual.

I suppose in theory it would cause an effect on the Moon's orbit, but I would think the effect would be WAY too small to measure.

the tides are already affecting the moon and the earth. The moon is orbiting further away than it used to be.
The earth is rotating slower than it used to.
if we use tide power of not will not matter to the moon because its orbit is already changing.
it is moving away at 3.8 cm per year.

Just like global warming man cannot have that level of effect on the planet. These are delusions of grandeur.
