to go from an ellipse with
perihelion at 50SR and aphelion at Jupiter, to a hyperbola with the same
perihelion but 50km/s of velocity at infinity, would require a burn
imparting about... 15km/s if the back of my envelope is correct. That's a
whole lot for a chemical rocket, and one constraint of the Oberth effect
is that the whole burn has to be near perihelion, so electric probably
isn't going to work for that.
