I am working on designing an underground city for my Kepler Bb story. I am now at the civilization phase and there are 100 people(Not including Robin, Lisa, Alma, and possibly 1 or more little ones) in a 1:1 gender ratio under these constraints:
- No younger than 15
- Not pregnant
- Doesn't have a child younger than 10
- Not ill
Now to prevent inbreeding, all children should mate not with family but with unrelated people.
Anyway, when I thought of what should power everything in the city here is what I was thinking.
1) Since underground is relatively close to the water table, I don't want any pollutants.
2) I don't want electrolysis since that wastes water.
So I figured pure electric is what I need and Solar would fit the bill really well. I took into consideration along with those 2 statements above that the solar system Kepler Bb is in has 4 stars in a close double binary system and the planets orbit around all 4 stars and that their daytime length, even in the darkest of winters, is longer than ours. So that means, even if they have the same solar technology as us(which I doubt very seriously since people on the very high tech planet Kepler B# send stuff to the people on Kepler Bb who aren't high tech to help them through the process of forming a civilization. Eventually, the people on Kepler Bb will be able to produce Kepler B# technology and possibly improve upon it.
As for vehicles, those won't come until later, after a civilization is established so for now all traffic is foot and hand traffic. Why foot and hand and not just foot you might ask? Well the people on Kepler Bb are equally able to be quadrupedal and bipedal though most of the time they are bipedal. When they go through underground tunnels however, if it is mostly up and down they simply climb it like they would climb a tree. If it is quite a bit horizontal though they get into their quadrupedal position. Because of this, they have injury resistant back muscles so going through an underground tunnel would rarely cause them to pull a muscle. They might be sore though and that's normal.
But when vehicles start being used, I figured that there should be solar charging stations if the battery is low and spare batteries if they can't get to a charging station in time to recharge their batteries either because of urgency(like running out of time to get to a meeting) or because of distance and battery use at their speed.
But would this work? Can I use solar power alone to power a city(all the lights, all the electric equipment(like for example the interplanetary communicator), all the vehicles, etc.)? If yes than that's great but if not, what other renewable power sources would I need?
