Sails models

" In those times, interplanetary travel was commonplace, though interstellar ventures were still an exception. Rocket ships would take the tourists to fabulous locations on Sirius, or the finance people to the stock markets of Arcturus and Aldebaran. But Jinn and Phyllis, a wealthy and free couple, were known through the Cosmos to be young originals, with a bit of craziness, and they would cruse through the Universe just for the fun of it - with their sailcraft.
" Their ship was a kind of sphere with a shell - the sail - made of amazingly thin material, and it would move through space, just pushed by the pressure of light beams. "

Excerpt from "The Planet of the Apes" by Pierre Boulle.
