Fictional energy source ideas? Pls help me out, I rly don't wanna use AI :(
Hellooo people who are hopefully better in physics, or whatever this is, than me lol
I'm currently working on a sci-fi graphic novel and I already have the general history of their planet but still miss the main energy source.
The timeline is basically:
- humans on our planet (or similar parallel universe) sent out a rocketship to search for a planet B
- the rocketship went through space for hundreds of years, then it got crashed by (idk yet)
- the part of the rocket that contained all their laboratory probes and also the fuel tank lands on the current planet
- this sends an automatical emergency signal back to earth
- by now earth is basically ruled by AI and unlivable, but the rich had enough time in their bunkers and found a way to actually make a wormhole work
- so they travel to the coordinates the original rocket collapsed and find the planet
- in the time the signal traveled back to earth new life from the probes and bacteria.... formed at the current planet
- the rocket tank evolved into the main energy source
- the big bosses of the humans claim this as their own and build a society around it
- now it's already a few hunderd years later
The question is:
What energy sources could that be?
Is there something that could be in theory fused from a rocket fuel and something that could be naturally found in a foreign planet? Or some occurrences that could get activated by the crash?
I'm lost here and really need some smart people to help me out. And I really don't want to use AI.
Thank you so much !
