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, [10] the Italian monk Francesco Lana de Terzi envisioned a ship with four vacuum spheres.
Jesuit Father Francesco Lana de Terzi describes in his treatise Prodomo a vacuum-airship-project, considered the first realistic, technical plan for an airship. His design is for an aircraft with a boat-like body equipped with a sail, suspended under four globes made of thin copper; he believes the craft would rise into the sky if air was ...
Francesco Lana de Terzi's airship c.1670. One of the earliest proposals for a flying machine based on rational principles was Francesco Lana de Terzi's design for a vacuum airship, c.1670. He had measured the pressure of air at sea level and based on this he proposed the first scientifically credible lifting medium in the form of hollow metal ...

Hypothetically, there could be an airship lifted by a vacuum—that is, by material that can contain nothing at all inside but withstand the atmospheric pressure from the outside. It is, at this point, science fiction, although NASA has posited that some kind of vacuum airship could eventually be used to explore the surface of Mars. [168]
