A vacuum airship, also known as a vacuum balloon, is a hypothetical airship that is evacuated rather than filled with a lighter-than-air gas such as hydrogen or helium. First proposed by Italian Jesuit priest Francesco Lana de Terzi in 1670, [ 1 ] the vacuum balloon would be the ultimate expression of lifting power per volume displaced.
Francesco Lana de Terzi's design for a flying boat, 1670 Francesco Lana de Terzi's flying boat concept c.1670. In the year 1670, Francesco Lana de Terzi published a book titled Prodromo, including a chapter titled saggio di alcune invenzioni nuove premesso all'arte maestra ("Essay on new inventions premised on the master art"), which contained the description of a “flying ship”.
The de Lana-Terzi's vacuum airship (1670) Theoretically, an aerostatic vehicle could be made to use a vacuum or partial vacuum. As early as 1670, over a century before the first manned hot-air balloon flight, [11] the Italian monk Francesco Lana de Terzi envisioned a ship with four vacuum spheres.
An airship, dirigible balloon or dirigible is a type of aerostat (lighter-than-air) aircraft that can navigate through the air flying under its own power. [1] Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift needed to stay airborne.

Texas law enforcement issued a word of warning to Ford truck owners after they arrested a trio of thieves who targeted the high-end truck model by stealing taillights.
The Ascender airship would operate between the ground and the Dark Sky Station at 140,000 feet (ca. 42,672 m). A long, V-shaped planform with an airfoil profile would provide aerodynamic lift to supplement the airship's inherent buoyancy, with the craft driven by propellers designed to operate in a near vacuum. The Ascender would be larger than ...
