These are thrusters used in orbit. We used to use compressed gas. Water is better because it’s doesn’t have to be stored at high pressure and can serve multiple purposes (coolant, consumption, etc.), the “problem” is that you need a boiler to produce the steam which in turn requires power. This test seems to indicate they’ve found a solution that meets size, mass and power requirements.
