Travel between Worlds
Since the existence of ether was proven as scientific fact, numerous inventions have been built to function from its use, none more prominent than Thomas Edison’s ether propeller, first demonstrated in 1870. This is the crucial device that allows vessels to soar between the worlds, carrying passengers from Earth to Mars, Venus, and even more exotic destinations. While interplanetary travel is hardly commonplace, it is an accepted facet of life in 1889.
Space voyages tend to be lengthy, sometimes lasting a month or longer. Ether flyers—as they are typically known—make use of solar boilers. A reflecting lens focuses the sun’s rays onto a boiler, thus producing steam to power the ether propeller and the rest of the ship’s systems, without the need for combustion or smoke (both of which tend to be lethal to spacefarers).
