In my history, at the year 2070 a billionaire owner of a big corporation is building a private floating city on international water, which has already attracted more than 200 million people wanting to live there, with the promises of individual freedom, almost no street crime, and a safe place to live in this turbulent world suffering after decades of pollution.
Everything in this city is powered by electricity: from cars and mass transportation to heating water and houses. Everything is powered by electricity because gas/fossil fuels are not desired.
City was built from the beginning to be very energy efficient and always economize when possible. No energy is wasted because the system grid is intelligent enough to distribute/store energy when necessary.
And because of that citizens use the average energy a citizen from U.S and UE uses today...What would be the best ways to power this city? I'm thinking about several thorium reactors and solar when possible, but how many reactors would I need? Safer and more efficient reactors than today is desirable.
Plants are grown in massive vertical skyscrapers using aeroponics with 100% optimal conditions and free of diseases 99% of time
Animals aren't required anymore; we can just grow their tissues in laboratories free of diseases, much faster, and more nutrient rich.
Citizens follow mostly an occidental diet but still I've no idea how many vertical farms I would need to feed 200 million people with abundance.
Everything in the city is very efficient and optimized to require the least water possible and consequently less energy too (e.g toilets don't need water anymore).
It's a closed system: nothing is wasted, everything is recycled and treated to reuse again on system.
The city collects all the rain, and takes water from the ocean, removes the salt, and puts it in the system...because it's a closed system, I just need to add additional water when needed and not keep the constant purification of ocean water.
- They are also building a massive automatized, high technology industry complex to produce most industrial goods (from drugs to car and phones and etc), since buying these from other countries would make country debt too big, and buying raw resources are far cheaper.
Am I missing something? Or can't such a massive city be self-sufficient? I want everything to be the most possible/realistic possible...
I'm building the city using designs and materials tough enough to resist earthquakes/tsunamis/nuclear or bomb attacks. The owning corporation has developed a very resistant and lightweight alloy with the help of nanotechnology that will be used for this purpose.
By self-sufficiency, I mean I want the city to meet most of it necessities alone and only buy from other countries raw materials/resources.
City is funded by the biggest corporation and owner of the project(they have alone 2 trillion dollars of capital) plus almost all countries ( all of them want a little of the tech we are using here) and by a deal with other big corporations (on this history mostly of the biggest companies merged into single powerful corporations) promising them monopoly over some areas.
People floods coming to city because the world is almost a desert now, with many governments becoming oppressive and the third world war is imminent, this city and the tech needed to create is the hope for a better world and future for the humanity itself.
