A Dyson sphere is not realistic because of the tremendous forces and instability of the structure. So maybe the same question could be asked for a Dyson swarm. … Also a 2020 review article on Dyson spheres by Jason Wright provides insights into the question of optimal size of a Dyson sphere. …

One proposed design for a Dyson sphere is the Dyson bubble, which consists of statites (satellites that use light pressure to counteract gravity). … Of course, this means the statites would now have to move relative to the star, which removes some of the Dyson bubble's advantages. …

Does Mercury have enough mass/raw elements to construct an Inverse Dyson Swarm/Bubble (for lack of a better term)? … Inverse Dyson Swarm/Bubble Wiki -- a lot like the Dyson Bubble around the star, but instead it is wrapped around an individual planet. …

Dyson sphere, a concept coined by the physicist Freeman Dyson, is a solar megastructure built around our Sun to harvests most of the radiated energy from it. … While this sounds impossible for now, some of its variants look promising in the near future, for example a Dyson swarm or a Dyson bubble around the Sun. Do we have the technology to do that? …

I've been reading a bit about the concept of a Dyson Swarm and how one of the more plausible routes would be to disassemble Mercury to construct ~1km hematite mirrors as the swarm reflectors. …

A Dyson-Harrop satellite is designed to generate energy from the stellar wind and is estimated to be able to generate 1.7 Megawatts using just 300 meters of copper wire. …

In this video from Kurzgesagt they said that one would need to disassemble a whole planet to build a Dyson swarm around the sun. …

A list of my thoughts/assumptions we have a good understanding of how stars live and die, so a "healthy" star (I assume you would only build a Dyson sphere around a star that's going to last a long time …

In the Wikipedia article you referenced, the Dyson Swarm constructs orbit around the star - standard orbital mechanics would apply, but traffic management might be interesting. … Further down in the same article, the Dyson Bubble has non-orbiting (& extremely lightweight) constructs that balance the solar sail pressure with gravity. …

Some modelling suggest Dyson spheres would be easy to detect due the fact they will be radiating close to 100% of the parent star's energy output, but over a much larger area and lower temperature producing … Related: A previous 2013 answer from Astronomy SE Answer on hiding a Dyson Sphere on Physics SE …

The Dyson-sphere is gravitationally unstable. The planets have a circular orbit, but a the Dyson-sphere is a sphere. Where could it rotate? … We could do in same decades, we would only need a peaceful, well-organized humanity for that :-) But building a Dyson-sphere is far, far away. There is nothing from which it could be built. …

But maybe they flew a fitted spacesuit up ahead of time for Dyson just to free up cargo space on a potential future rescue flight. … If that is the case I wonder if they had planned to send the suit back later on a cargo Dragon after Dyson departed the station. …

So basically a Dyson Sphere/Swarm around the sun or earth. This would still allow light and other radiation to reach the earth or all the other planets, just less. … He does have videos about power satellites, dyson spheres and a lot of other topics which fit your question. …

With regards to Project Orion, nuclear pulse engine, could the 0.015 kiloton up to 0.35 kiloton Deuterium/Lithium bombs proposed by Freeman Dyson be constructed? …

I'm coining a new phrase: "Dyson circuit". …
