"Weighs 500lbs and only generates 5 Newton’s of thrust."

~~~~~~

Actually, it.s 5.4 Newtons which equals a whole 1.214 lbf...

Somehow, for 102 kW, with electrical current of up to 260 amperes, a little over a pound of thrust doesn't seem too exciting.

Of course, I guess one has to ask, "What is the reaction mass consumption at that 1.214 lbf level?

In outer space, there is no friction. That means all of the thrust goes toward accelerating the vehicle. It just goes faster and faster. If the thrust can be maintained over a long period of time, all you need is patience, and you will be traveling really fast.
