One potential compromise, according to the study, is constructing a Dyson swarm at 2.13 astronomical units (AU) from the sun. This setup could capture around 4% of the star’s energy—equivalent to a staggering 15.6 yottawatts—while increasing Earth’s temperature by less than 3 Kelvin, an impact comparable to current global warming trends.
However, even this partial structure would require an enormous amount of material, estimated at 1.3 × 10²³ kilograms of silicon.
