Dyson Sphere Energy Capture Simulator

A rigid Dyson sphere is a continuous shell around a star, while a Dyson swarm is a large collection of independent orbiting collectors. Most engineering discussions favor swarms because a solid shell would be structurally unstable and extremely material-intensive.

It estimates the distance where collectors radiating from both sides reach the selected operating temperature under the chosen stellar luminosity. Hotter collectors can orbit closer, while cooler collectors require larger radii.

The Kardashev value is calculated from captured power using the common logarithmic form K = (log10(P) - 6) / 10, where P is power in watts. A value near K1 represents planetary-scale energy use, while K2 approaches full stellar output.

It is an educational first-order estimate based on collector area, areal density, and a stability factor. Real designs would need station keeping, power transmission, mining losses, redundancy, heat rejection, and manufacturing infrastructure.

High-luminosity stars push the safe thermal radius outward. That increases the surface area needed for a given coverage fraction, so material demand can rise faster than the captured power feels intuitive.

Yes, if the host star is bright enough and the collectors are efficient. Around a Sun-like star, reaching near Type II requires capturing a major fraction of solar luminosity, but around more luminous stars the same power target can need lower fractional coverage.
