Depicts the lightest mass variant of a magnetic accelerator - the rings are powered by automated solar panels and propel a mass (in a metal cannister) of several kilogram along a several ten mile track, per second. That means - something like a ton of material per minute, ejected from lunar surface into orbit in a very precise orbit. Yes, this thing scales.

You can jumpstart an industrial revolution this way, at relatively modest investments. If only we human beings had any faith in real things.
