What's your timeline for a lunar mass driver? John sets 4 conditions for it to count as real: 1. A permanent electromagnetic launcher is installed on the lunar surface (obvious). 2. It must launch at least 300 metric tons over a 12‑month period, meaning it’s moving significant mass, not just test payloads. 3. 95% mission success and at least 200 launches per year. Failures will happen, but the goal is reliability at commercial scale. 4. The mass launched from the moon has to be put to use. This can’t just be a demo unit blasting rocks into the sun. It's got to be something useful.
