Summary: Which of these hypothetical propulsion methods is the best for a spacecraft during Interplanetary flight? Let’s just assume all at this point are cost-effective at the time.

Consider the
•Safety of the engine

•The speed

•The efficiency


1.) Monoatomic hydrogen propulsion

2.) Metastable Helium propulsion

3.) Nitrogen-20 propulsion

4.) Thermonuclear micro-bomb propulsion

Looking for something humans can use for the future of spaceflight.
