# Thread: Which Drive Would You Pick For A Starship?

1. These are sub-light drives you pick for maneuvering (warp drive is a given).

Newtonian Orion Drive: newtonian maneuvers via nuclear fusion and also by blowing up nukes in space for your massive reaction thrust.

Weakness: It does newtonian maneuvers. If you consider that a downside. No airplane maneuvers in space. Just linear maneuvers with epic drift until you thrust in the opposite direction.

Automobile Drive: Yeah I made it up, but science fiction demands it. Spaceship has wheels that ride on an invisible floor from another dimension that ONLY interacts with your wheels. You can also tilt your ship in the direction you wanna go without thrusters.

Weakness: You run on a type of compressed gasoline. Super compressed so your ship can carry more of it. Nonetheless when you run out, you run out. The only way to get more is at space gas stations. It doesn't occur naturally in space. Because your in space, your ship won't stop even if you turn off your engine, not unless you put on the brakes. So long as your brakes are working, you can stop. Also, if your wheels aren't spinning, then you won't be doing any tilting of your ship. In fact you won't be going anywhere.

3. How about an Omnidirectional Exo-Gravitation Array?

An ODEGA will let you generate a "pocket" of gravity in whichever direction you want to travel, so your spaceship just "falls" forwards/backwards/sideways/etc. Not sure how to figure out a way of turning the ship around to face a different direction, probably with some technobabble like "torque manifold" or some such.

It thought about a gravity drive once. In fiction the problem is it HAS NO WEAKNESSES. It's perfect. And in real life NOTHING is perfect. So I prefer drives that have some weakness in them.

I thought of a drive that is essentially powered by a telekinetic person. The only weakness that it won't work when the person is sleeping. And you can't have more than one telekinetic on board since they cancel each other out power wise.

This, ships like these travel in packs of four, to rotate telekinetic powered people around.

5. Why would a fantasy starship engine need a weakness?

Weaknesses are for people, not technologies.

I do concede, however, that technology without limitations can lead to poor plot resolution (becoming a deus ex machine) or even leading to "Magical Computer" scenarios. But something that's "only" a propulsion system is already pretty limited.

Weaknesses in propulsion systems affect society in fiction. Say the automobile drive can drive for 4 months on a gallon of fuel. That means if it carries a 1000 gallons it can fly for years.

It also means that it would be a prime target for pirate ships with smaller fuel tanks.

I like it cause it breaks physics and follows them at the same time. Just think of a car that can tilt an imaginary road wherever it wanted to go and the wheels stuck to the road. That is what it's like.
