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.

The opposite happens. Tidal energy is what causes the moon to drift farther away from the earth, as the moon loses angular velocity.

Hopefully the new maintainer can get releases going again. It’s a great extension!

If you’re talking about the extension that looks like an R with a green arrow, the author passed away a couple years ago. https://github.com/einaregilsson/Redirector/issues/329

The repo has a new maintainer but there’s been no new releases since the maintainer doesn’t have access to the extension release pages. No surprise that a MV3 version hasn’t been worked on.

It still works on Firefox, though.
