Study Warns Full Dyson Swarm Would Make Earth Uninhabitable

Research proposes a partial Dyson swarm at 2.13 AU as a feasible alternative for harvesting solar energy while preserving Earth's habitability.

A full Dyson swarm outside Earth's orbit would raise global temperatures by 140 K, rendering the planet uninhabitable, according to a new study.
A partial Dyson swarm at 2.13 AU from the Sun could harvest 4% of solar energy while increasing Earth's temperature by less than 3 K, comparable to current global warming trends.
The concept, first theorized by physicist Freeman Dyson in 1960, envisions a network of satellites orbiting a star to capture its energy output.
Constructing a partial Dyson swarm would require 1.3×10^23 kg of silicon and advanced engineering solutions to address temperature regulation challenges.
The study, published in the journal Solar Energy Materials and Solar Cells, highlights the balance between meeting energy demands and maintaining Earth's habitability.
