Agree. I do not deny that wiki is crap nor do I deny the fact that pykrete is/might be a viable solution. However we're talking about cities floating in water on this thread and on earth where the temperatures fluctuate drastically in different oceans. Space applications is a whole different challenge.

wiki is utter crap. Maybe you consider the insulation capability of aerogels to insulate pykrete. Also in space especially beyond Jupiter,temperatures are in minus.Which means that Pykrete can be used for o neill cylinders without insulation.

Cities like these might provide hope for the future with overpopulation being an issue in the coming decades (not that it isn't an issue now).
thats all well and good if your a trillionaire but what about regular folks?

in my opinon ,both can work.But it will be easier to use the anti gravity pathway as an existing city could be transformed into a flying one via means of anti gravity generator.
Cities in Flight is an omnibus volume of four novels written by James Blish, originally published between 1955 and 1962, which became known over time collectively as the 'Okie' novels. The novels feature entire cities that are able to fly through space using an anti-gravity device, the spindizzy. They cover a span of time of many hundred years, from a very near future to the end of the universe. 'Earthman, Come Home' was a winner of a Retro Hugo Award in 2004 for Best Novelette.
The Cities in Flight Novels
They Shall Have Stars
They Shall Have Stars (1956) (also published under the title Year 2018!) describes the political and social conditions in the near future when several major technologies are developed which change society radically. These are 'anti-agathic' drugs, which defer or prevent aging, and the development of gravity manipulation, which leads to 'faster-than-light' spaceship drives. During this period the Western democratic government model becomes ever more intolerant, eventually resembling the Soviet model very closely. A principal protagonist of this book, Alaska's US Senator Bliss Wagoner, is eventually executed by an oppressive regime, but not before he has made the technologies which allow mankind to escape their home planet available to all. The book is notable for the detailed way in which it handles technology, providing a mathematical explanation of the principles behind the anti-gravity drive, and illustrations of chemical bonding for reactions in the Ice IV material which is used to build a fixed point 'bridge' on the surface of Jupiter during the drive testing. Politically, the book clearly expresses a strong opposition to McCarthyism, at its peak during the time of writing.
Reviewing a later edition, the Hartford Courant described the novel as "a skillful mixture of human reality and technological fantasy."
A Life for the Stars
A Life for the Stars (1962) describes the adventures of a young farm boy Chris, co-opted into an Earth city (Scranton, Pennsylvania) which has begun travelling in space. The development of the anti-gravity (spindizzy) drives has now enabled very large objects to be enclosed and moved using gravity manipulation. Thus, for instance, mining factories together with associated towns can be moved to bodies of ore, not only on Earth but also amongst the planets in local space. Many of these 'Okie' cities are rejecting Earth jurisdiction, making interstellar journeys, and operating a trading economy out of reach of the Earth authorities. After many adventures Chris eventually becomes a resident of New York, now a major 'Okie' city under its charismatic mayor John Amalfi, being elevated to the newly-created position of city manager due to having a unique, problem-solving skill-set identified by the City Fathers, which are supercomputers who regulate the day-to-day life of the flying city.
