So if I remember correctly, there was something about there soon being a need for energy? Like we'll have fuel for thrust and reactors to power everything else? Well what if there was Gas Giants, and we could harvest Hydrogen and Helium from them in order to fuel Fusion Reactors? But of course it'd have to be an on ship mounted tool that gather's the gas, and it'd be a dangerous job as if you get too far in the gravitational pull of a gas giant, there is no amount of thrust that can save you.
