I was wondering what kinds of things would be required for an underwater city such as dimensions maximum feasible depth maximum feasible height minimum size etc and what kind of general problems would need to be eliminated and possible solutions.
ps. I mean this a beginning of a general discussion so if you have any ideas please share even if they don't address these specific items

as of right now there really can't be any underwater development in terms of real estate and cities such because transportation would be difficult.
standard internal combustion is out for obvious reasons.
nuclear is out for a publicly available transportation method for equally obvious reasons
so what would be kind of propulsion would work best within the restraints that it has to travel long distances most likely aprox. 200 mi and pressure at whatever depth the destination would be located at presumably at depth no greater than 400 feet.
without a recharge/refuel has to be affordable to people who are not necessarily extremely wealthy. and be able to handle waves and ocean currents and allow for comfortable breathing for extended amounts of time.

I have to build a scale 6 story model tower with 4-6in per story to survive on a shake table (to simulate a earthquake) out of raw spaghetti noodles and hot melt glue. 100 gram weights will be placed on the 2nd 4th 6th floors.
I need to know how to calculate the forces that the model will endure and the strength of the model.
i was thinking of incorporating the following design features.
cross braces (forming triangles)
have the tower tapper in from the base until it reaches the 4th floor where it will stop tapering and continue at the same width. I need to know if these will help.
we are also supposed to build a base isolation system idk enough about the materials that will be provided to talk about that yet.

As a teenager intrested in polotics how does someone get into polotics?

something I've been confused about for a while.
I understand the idea of how it works but the current level of the development of the technology is not clear.
i have heard several things recently on the topic.
1.) it is now known fact that cold fusion is impossible
2.) fusion has been established but the energy required to initiate it was greater than the output.
3.) fusion has been established but the hydrogen production requires more energy than the fusion produces or is to dangerous.
4.) fusion has not been established because we have not been able to achieve the energies required.
5.) robotics are not developed enough to maintain the reactor.
6.) none of these things are problems it is just a mater of the economics of it.
ps. I do not feel this should be in speculation but because I did not know where to put it and because it has potential to stray from strictly accepted science I placed it here if you (mods) believe that this thread is worthy of a more respectable section please move it.
