Dyson Sphere
People have proposed the idea of building a Dyson Sphere around a star. What's the proposal to transmit the energy to somewhere we can use it? How would we do this?
The most modern idea seems to be a Dyson swarm, which is not solid and consists of solar panels and habitats orbiting at a comfortable distance. Power is relayed using microwave transmitters and receivers and conceptually a large portion would be fed into particle accelerators for the manufacture of Anti-Matter on industrial scale.
I thought you'd build a sphere or swarm at a radius from the sun that got enough solar radiation to be at a comfortable temperature. Then you'd live on the inside surface.
