Reply to comment by quettil in Would building a Dyson sphere be worth it: We ran the numbers. by filosoful

You're assuming all the materials are useful. While infact you need metals. Luckily mercury has an iron core. And we were talking Dyson sphere not swarm. A swarm would be much easier, as it requires much less material, much less stabilisation. And you can construct it a segment at a time.

A Dyson swarm at 0.1 au would also be very toasty.

A Dyson sphere is a swarm. Sphere is a misnomer. It was always a swarm.

Friedman Dyson proposed an actual sphere. But in practice the sphere would be very difficult to keep in orbit. A small imbalance and it would destabilize and fall into the sun.

Swarms are much more easily executable.

They are not the same thing.
