But does harvesting it make it go faster or slower away?

[–] excess0680@lemmy.world 1 points 11 hours ago (1 children)

If you mean harvesting tidal energy, the effect on the moon would be minimal. The loss of angular momentum the moon experiences is due to the mass of the earth’s waters. I could not imagine anything humans could build that could extract enough tidal energy that it would disrupt the moon without utterly destroying the environment at the same time (by way of nullifying tides somehow). In fact, to harness tidal energy, one way would be to use underwater turbines. They would have an immediate effect to the local environment but a negligible amount to the moon itself.

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.
