"The floor upon which the entire city rests is steelonium, and the city is held up by means of anti-gravitational impulse. By neutralizing the gravity for the area below the floating city and a little beyond it, it is possible to keep the floating city at any distance from the earth. In other words, we use a gravitational 'screen,' and then build a city on top of this screen.
"By charging the gravitational screen at a very high potential, we nullify gravity and as the city no longer has any weight it can be placed on any level and remain there practically indefinitely. A few air propellers keep the city from being blown away by storms or wind.
"Although it was very cold in our aeroflyer as we came up, it is nice and warm on the streets here. Nor is there any artificial heating during the
