How to build a Dyson swarm around the sun

While such a gargantuan undertaking is clearly unfeasible at the moment, it’s never to early to start planning!

Unlike a shell-like Dyson sphere, a Dyson swarm would be composed of living habitats, satellites, and solar energy collectors orbiting like a net around a star. Energy would be transferred wirelessly between the individual components and Earth. Alternatively, millions of mirrors could be used to focus light onto a fewer number of collectors.
