The Annotated Journey
science fantasy describing the use of 'apergy' as a propulsive force.
Much akin to what today is called 'inertial propulsion'. Many devices
have been built using this principle as well as patents granted, most
notably, the Dean Drive, Cook and Thornsen drives. Often science
fantasy and science fiction is used to propose concepts beyond the
science of the time. The idea of using the inertia of a mass as a
driving force is yet to be tapped in practical devices though many
experiments show the concept is valid. Written in 1894 and includes
additional supporting material from modern research.
