There's two propulsion technologies in use today. Rockets and ion/plasma drives. Rockets generally pull a few gs for about ten minutes or a few tenths of a g for an hour or so. Ion drives can pull milligees (due to the power/weight ratio of practical power supplies- carrying the weight of the power supplies limits the acceleration).

There's nothing, other than an infeasibly big rocket, that can generate 0.1g for months. That would be a tremendous advance if anyone worked out how to do it.

As an exercise, take a one tonne capsule and calculate the work done to do that from force x distance. You'll find it's ... large.
