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:
