In certain universes, creating a city that floats in the air is not that hard, especially if one has access to magic or science that is beyond our understanding. However, what if all of that was taken away? What if the architect who had to design a floating city had only access to current technology, or something that is just a little bit more advanced than the current technology of humanity? There are just simply so many problems with a floating city in real life. Your exercise is to make a realistic floating city, or at least try to make it as realistic as plausible, then describe it in a few paragraphs. Here are some ideas to help you with that. Some ideas on how to start: - There are certain materials, called diamagnetic materials, that very strong magnets can float. - The method of floating should definitely not rely on fuel. - Blimps are a very secure method of lifting weight, but they need to be big enough. - Even regular magnets decay over time, and electromagnets would make it impossible to use electric equipment in the city. - The lighter materials this city is made out of, the easier it is to keep it lifted. - It is also possible to use some sort of fluid to help support or cushion the city. - Realistically, there should be multiple levels of redundancy that keep the city floating so it is safe. - The city does not need to be one big hunk of rock floating in the sky. - Suspension can work wonders.
