A craft that can sustain a 1g thrust for three days straight is the most outlandish idea in this entire thread.

talking about how it would be cool if we had a ship that could do that, and the implications of that. In no way is anyone with any serious education actually talking about HOW to possibly get a craft with the mass fraction and specific impulse to pull this off. we are several orders of magnitude off of this being possible when it comes to specific impulse, and the highest impulse engines we have have nowhere near enough thrust to weight.

Seems there are several thruster designs aimed towards this goal:

And at NASA:

We just need a craft that can thrust that strength for three days straight.
