Helium-3 is a fusion fuel that exists in trace amounts in lunar regolith. Whether mining it makes sense depends entirely on how much power and processing you can bring to bear. This planner turns those variables into concrete daily and annual yields, the power each stage draws, and the export economics.
It is built to make the scale of a helium-3 operation legible — how much solar you need, how much power is left for everything else, and how many export launches per day the output implies.
Yield scales with how much regolith you heat and process, because helium-3 is released when regolith is warmed. The model tallies the power drawn by mining, thermal separation, and launch, then subtracts that from your solar budget to show what remains for base operations.
Because concentrations are tiny, helium-3 mining is power-hungry per gram; the planner makes the trade-off explicit so you can judge whether the export revenue justifies the enormous energy and how much solar overbuild it demands.
Dedicating a large slice of a multi-hundred-megawatt solar field to helium-3 yields only kilograms per day, which is why the tool reports both the revenue and the sobering fraction of your total power the operation consumes — the number that decides viability.
It is speculative and power-intensive; this tool helps you reason about the scale rather than assert feasibility.
Helium-3 is present in parts-per-billion concentrations, so even large throughput produces small masses.
Thermal separation and, if you export, launch energy; the model shows the split.
