Ask HN: 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?
- bediger4000 3y agoI 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.
- p1esk 3y agoWhat about gravity? Rotate the sphere?
- solardev 3y agoIf you make each sail in the swarm light enough and self-adjusting, radiation from the star could keep them in place... here's a detailed writeup (not mine): https://canmom.art/physics/dyson-spheres https://canmom.art/physics/dyson-spheres
- solardev 3y agoPewpew it as lasers? That YouTube K-animation channel I can't spell (Kurdurkistan?) has an episode on it: https://youtu.be/pP44EPBMb8A?si=b8qssNFtMDAqUyE_ https://youtu.be/pP44EPBMb8A?si=b8qssNFtMDAqUyE_ There's also the great engineering/factory game Dyson Sphere Program: https://store.steampowered.com/app/1366540/Dyson_Sphere_Program/ https://store.steampowered.com/app/1366540/Dyson_Sphere_Prog...
- thedevindevops 3y agoThe 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.
