Puffer

Cicero in his Offices declares his opinion , that a vendor ought not to appoint a puffer to raise the price

This is the next best thing, which is a pseudo-puffer made by converting a stream of spaceships into puffer output using several c/3 spaceships.

Might be interesting to see if the debris from this puffer can be suppressed somehow -- assuming somebody hasn't already done that, but I don't see any sign of previous attempts.

The switch engine is unstable but a number of them working in combination can form stable puffers, spaceships and rakes.
