plantfanatic comments on South Korea’s artificial Sun ran for 102 seconds and it could change the future of energy

Can it be used to power a turbine? Or just propulsion like a sail, because what if we want to go towards the sun…?

It also has diminishing returns in relation to distance to the sun.

Sails can power turbines.

In space…? Because that requires moving one part while the others stationary…. The friction from generating power would spin the rest of the satellite, or would need to expend power to resist it.

Windmills have used sails as fins for long time lol, its nothing new, im trying to get you think critically here.

Or moving one part opposite the direction of another, to create resistance.

There's plenty of conversation to be had about efficiency, heat venting, gross productivity. But "you can't capture energy from another moving body" is something billards disproved several centuries ago.

Just because you can capture it doesn’t mean it’s useful or beneficial.

Not much science could be done with a constantly spinning satellite. And spinning stuff in space does some weird shit, we already know this.

Virtually all of science has been performed on a constantly spinning satellite.

Does context just not exist to you?

My god are you twelve? Using someone’s random Lemmy server address as an insult. I’m sure you know what people think of yours… but it makes no difference to here. Again the context eh?

Fucking lol.

No, I just can’t believe people like you haven’t been banned off this place yet. You’re exhausting. And looking at your comment count, there’s no way you can be making any conversations in good faith.

You’re just an absolutely pathetic troll, you make the other ones look decent.

Yes I do, it’s frustrating that the mods of Lemmy.world do nothing and this crap bleeds everywhere. And the admins don’t care, since curtailing it would tank their statistics.

lemmy:	0.19.20
