Since the linear momentum of the isolated system must remain zero, the raft must acquire a linear momentum that is equal in magnitude and opposite in direction to that of the sunbather. From the definition of linear momentum, ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
