Question about copious electricity on a world that’s basically tech level 6
That tech level is from a role playing game called Traveler, which is basically like D&D for sci-fi.
TL6 is more or less 1940s-1950s technology on earth.
I’d like to create a setting in a sci-fi story that is set in that tech level, but instead of using internal combustion engines, I’d prefer to depict engines as electric. And because the story would have a military dimension, the electricity can’t be generated and accessed at fixed points like the charging station for an electric car. It needs to be more easily accessible to an army in the field. (That’s not possible on earth — that’s why there are no electric tanks for instance.)
The problem is, where is the electricity coming from? I don’t think this would have been practical on earth in the 1940s to 1950s — it’s just too difficult to generate all that electricity and store it in batteries.
But what would need to change about the planet to make it more electricity rich? So that it is available to run the engines? The planet itself needs to have an atmosphere similar to ours, it can’t be some dead world.
Is there potential for such a planet? Or is this an impossibility?
