Earth Based Technologies
Many technologies of the pre-apocalyptic Earth colonies were, unsurprisingly, based off of Earth technologies. Earth based technology usually ran off of a crude fossil fuel and broke very easily. Many times the reasoning behind owning it was for the novelty of owning the technology rather than for a practical use. Thus, Earth-based spacecraft often needed a carbon based fuel to operate, making them very ineffective outside of Sol.
