It doesn't have a engine made out of matter, the fusion fuel is ignited 10m away from the ship using Z-pinch, neutrons and x-ray can just escape the core into space, the exhaust plume is being formed through very thin superconducting coils, it's open-cycle. I wonder if I do the same with my amat-initiated fusion... No... Anyways, you're using the outdated version, so I guess I'll upload the newer version so you can adjust it. The total heat output should be the thrust power divided by fraction of itself in total fusion power, then multiply the total fusion power with fraction of waste energy that can't be redirected. |

It's a side effect of using a Z-pinch design, they have several interesting advantages if you work long enough on the design details. I don't know how that would be a problem, I have 2x 1GW reactor, one for weaponry and the other for the Z-pinch device. Or is the old fusion completely of? This bring brings me to 1.33TW of 1.72TW Radiators instead of 1TW. |

DD is added, too. The firefly concept uses DD. |

"Monatomic Boron" pointer. You forgot to add the Monatomic elements from the older versions, someone new won't know that you need the p-B11 + D-T + D-He³ old fusions to make the new version work. |

BTW what thrust-to-weight ratio should a fusion drive have? Something like 300 may be WAY too high...  |

BTW what thrust-to-weight ratio should a fusion drive have? Something like 300 may be WAY too high... For real life or CoaDE? For real life: Absurdly high, the engines would consist of superconducting coils and your ignition device of choice. They will be mostly empty space. For CoDE: It's actually pretty ok, it depends on how thin you can make your engine bell. The thinner the more it can radiate from itself, but at some point the pressure would destroy the engine. Using graphene makes this relatively easy. Thrust-weight ratio can never be to high, I think you meant weight-thrust ratio. |

Maybe I should say it in another way: do you think that a fusion drive with 50 TW thrust power and 1.4 ton mass is really probable??  |

Uh, If you use a very light Ion gun with antiprotons as fuel, and use 1200kg or so of superconducting coils with extremely lightweight and efficient cooling with enormous currents, sure why not. Why do you even need such a lightweight engines anyways? |

The AstronomerI added some extra radiators for my reactors, now I can collapse my radiators and fully protect them from outside harm. Your updated costed my 250mG of thrust thanks to the lower exhaust velocity, please increase the exhaust velocity to 75%. So it matches the actual thermal particle percentage and my needs.

The energy is at 75%, so I don't know why is the exhaust v is at 66% of the theoretical exhaust v.
