Dyson Sphere does not affect Terra Palus. After installing the energy repeater in orbit and getting it confirmed by the message in the chat (after 100 rocket launches), the energy connectors (MK1) do not provide any energy to the grid (no other energy sources applied). (I have about 5k satellites around the sun)

Oh, and btw - even tho there is an 8-minute day-night cycle - the solar panels never generate any power either.

If you haven't already, I would strongly suggest posting this up in the Dyson Sphere discussion tab as well, since they are the ones who would need to fix that

I imagine that this is because the planet is supposed to be "perpetually shrouded from direct sunlight", it's likely that planet has some property of the planet set to zero, which breaks whatever math Dyson Sphere uses. Or I might be completely off, I have no clue how the mod works, but there's no planet-specific code in it, as far as I can tell.

done - thx for your feedback ;)

I've just found out that it doesn't work on Nix either - but it works on Nauvis and in Space. It seems to be a problem with the Dyson Sphere.
