The piston pump can be powered by the gas pressure from the gas
generator. Looks like the screw pump requires either electric motor -
with heavy batteries - or a gas turbine, which could be more complex.
When you run the numbers the energy density of modern batteries compares
quite well to the kinetic energy extractable from decomposed peroxide
monoprop in a practical steam engine. I did a presentation about this maybe
10 years ago at space access because when I looked at the numbers I was
floored by how good batteries are nowadays.
