Robert Zubrin's Nuclear Salt Water Rocket (NSWR) design is a rocket that uses known physics and engineering . There are ...

[The Q] is one such experimenter, who built a dual-thrust water rocket that even has a parachute for landing! The testing took place in an area strangely reminiscent of a certain operating system.

When used as a rocket booster, it is filled with 66 Ibs. of water heated electrically to 504° F. The water cannot boil because it is confined, but its pressure rises to 50 atmospheres (735 Ibs.

But if he manages to avoid that fate, such a hearty rig should keep [Zach] flying for a long time. Perhaps it could even launch a two-stage water rocket?

While prototypes of water-powered rocket thrusters and engines have been developed before, and a few have succeeded in launching CubeSats, water has not yet been used as a propellant on a large scale.

AI gives a thumbs up to Brett Bellmore innovative modifications to Robert Zubrin’s Nuclear Salt Water Rocket (NSWR). Switching from water to polyethene and storing in sausage strings could enhance its ...
