Rockets can hold 100 concrete or 500 stone bricks.

A Foundry with 4x Legendary Productivity Modules will create 10 concrete from 2 stone bricks.

Water (from Ice), Molten Iron (from Iron Ore & Calcite) can be sourced from space.

Therefore a single rocket with 500 stone bricks will net you 2500 concrete. And now that we can transfer platform-to-platform this workflow makes more sense.

I know you can always just build more rockets, but there's fun in making things as efficient as possible. Yeah most asteroids around Aquilo are Oxide asteroids so you'll need Asteroid Reprocessing, or just send a second rocket's worth of iron ore with the stone bricks and you'll be set.

Anyone do this?
