Earth
In Jonathan Swift's satirical novel Gulliver's Travels, Swift envisioned Laputa, an island city that floated in the sky. The island was suggested to levitate above the Earth by use of the force of magnetism. In the 1920s, Hugo Gernsback speculated about floating cities of the future, suggesting that 10,000 years hence "the city the size of New York will float several miles above the surface of the earth, where the air is cleaner and purer and free from disease carrying bacteria." To stay in the air, "four gigantic generators will shoot earthward electric rays which by reaction with the earth produce the force to keep the city aloft."
Laputa (although uninhabited) is shown in Hayao Miyazaki's Castle in the Sky.
Although Swift's proposal was intended as satire, Buckminster Fuller proposed the concept more seriously in the form of the Cloud nine (Tensegrity sphere) megastructure, in which he envisioned structural spheres that float freely in the sky, allowing passengers a migratory lifestyle and a solution to the depletion of Earth's resources. He proposed a 1-mile-diameter (1.6 km) geodesic sphere that would be heated by sunlight, functioning as a thermal airship.

Famous quotes containing the word earth:
“A sleeping man holds in a circle around him the thread of the hours, the order of years and of worlds. He consults them instinctively upon awaking and in one second reads in them the point of the earth that he occupies, the time past until his arousal; but their ranks can be mingled or broken.”
—Marcel Proust (1871–1922)
“Under the one word “house” are included the schoolhouse, the almshouse, the jail, the tavern, the dwellinghouse; and the meanest shed or cave in which men live contains elements of all these. But nowhere on the earth stands the entire and perfect house.”
—Henry David Thoreau (1817–1862)
“It was a favor for which to be forever silent to be shown this vision. The earth beneath had become such a flitting thing of lights and shadows as the clouds had been before. It was not merely veiled to me, but it had passed away like the phantom of a shadow, skias onar, and this new platform was gained. As I had climbed above storm and cloud, so by successive days’ journeys I might reach the region of eternal day, beyond the tapering shadow of the earth.”
—Henry David Thoreau (1817–1862)
