The "hyperboloid" in its title is not a geometrical surface but a "death ray"-laser

. "Hyperboloids" of different power capability differ in their effect. The device uses two hyperbolic mirrors to concentrate light rays in a parallel beam. Most "hyperboloids" can destroy military ships on the horizon, and those of less power can only injure people and cut electric cables on walls of rooms.
A translation of the passage describing the device:

The rays of light, falling on the inner surface of the hyperboloidal mirror, converge in a single point, the focus of the hyperbola. This is a known fact. But here is the novelty: in the focus of the hyperboloidal mirror, I place a second hyperbola (shaped, as it were, inside out) -- a hyperboloid of revolution, made from a refractory, ideally polishable mineral -- shamonite -- endless supplies of which are found in the north of Russia. What, then, becomes of the rays?

The rays, converging in the focus of mirror (A), fall on the surface of hyperboloid (B) and reflect from it in a mathematically parallel fashion -- in other words, the hyperboloid (B) concentrates all the rays into one beam, a "filament of light" of any thickness desired.


There are two scientific blunders here:
  • The usage "hyperboloids" is wrong: it is the paraboloid

    In mathematics, a paraboloid is a quadric surface of special kind. There are two kinds of paraboloids: elliptic and hyperbolic. The elliptic paraboloid is shaped like an oval cup and can have a maximum or minimum point....

    In geometrical optics, a focus, also called an image point, is the point where light rays originating from a point on the object converge. Although the focus is conceptually a point, physically the focus has a spatial extent, called the blur circle. This non-ideal focusing may be caused by...
