Dyson Sphere Energy Calculator (2D)

This 2D top-down simulator visualizes a Dyson swarm: hundreds of collector satellites orbiting a star at scattered radii and inclinations, each beaming captured energy back toward a central hub. Drag the coverage slider to grow or shrink the swarm, switch between star types (or fine-tune luminosity directly) to see how a star's brightness changes the numbers, and watch the live readout compute real capture physics — total power in watts, where the civilization lands on the Kardashev scale, and how that compares to all of present-day human energy consumption.
