(10) Velocity to escape sun at Jupiter distance:
Vsun−esc−J = (2fsun/5.2 AU).5 = 18.4697 km/sec
(11) Delta-V to escape sun at Jupiter distance:
Vsun−esc−J - Vp−sun−J = 5.4087 km/sec
(12) Total Delta-V for Jupiter analysis Delta-V
Vtotal = 32.2954 km/sec

This is nearly twice the Delta-V required for the first case. This fact, along with the difficulties involved in mining the atmosphere of Jupiter, getting the fuel to a million kilometer orbit around the planet, etc., has made it obvious that obtaining fuel from Jupiter is not feasible.
