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 monk Francesco Lana de Terzi in 1670, the vacuum balloon would be the ultimate expression of displacement lift power.

Famous quotes containing the word vacuum:
“No, it wasn’t an accident, I didn’t say that. It was carefully planned, down to the tiniest mechanical and emotional detail. But it was a mistake. It was a beaut. In the end, somehow granted the time for examination, we shall find that our so-called civilization was gloriously destroyed by a handful of vacuum tubes and transistors. Probably faulty.”
—John Paxton (1911–1985)
