I have a legit question.

[I only have this kind of pictu(...) No.7126466]

If the satellites can indefinitely pull-push the liquid elements on the celestial bodies they orbit and that movement can be harvested as tidal power :

1 Is this a infinite energy source?

----1.1 In case it's not, where does this energy come from, gravity?
--------1.1.1 What are the effects of collecting this energy? In our case for example, are we altering the Earth's/Moon's orbits?

----1.2 In case it's, why aren't we harvesting it?
-------1.2.1 What the fuck happened to the law of energy conservation?

TL;DR Tidal power, how does it werk

Thanks in advance.

1. No, of course not, you retard.
1.1. Sort of. The moon's gravity pulls water higher up, it slumps back down as the Earth's rotation moves it away from the moon (this explains one tide, the other tide is sort of the opposite effect), tides are the result, and we can harvest energy from that slump-back-down part.
1.1.1. No real effects of harvesting the energy of tides. The moon's orbit is affected (slowed down) very slowly, as is the Earth's rotation, but the effect is pretty much immeasurable on human scales. The energy we collect would otherwise basically just disperse as heat eventually if we didn't.

1.2. We don't have the infrastructure in place yet, and there are questions about how it might affect shore ecosystems.
1.2.1. Nothing.

TL;DR not magnets, but gravity

tidal power is dissipated in two ways:
1. friction from tidal stretching. This is resulting in the Earth's rotation gradually slowing down. Eventually it will match the moon's orbital period, called tidal locking.
2. The orbiting bodies gradually moving away from each other. The moon is moving away a few centimeters a year.

These two things will reach equilibrium in about 50 billion years.

basically works like a swing set

a swing is a pendulum, but by exerting energy you can go higher.

now if you attached a generator to your swing that captures the pendulum motion you'd gradually slow down. to maintain the same hight you'd have to put more energy in.

in space the tethers are invisible and made of gravity, but the same principles apply. gravity is just strings.

the moon is dragging the oceans behind it, and if we slow the ocean down the moon loses energy. it's disappearingly marginal, but it's happening. and we are harvesting it.
