"I suspect that religion is a necessary evil in the childhood of our particular species. And that's one of the interesting things about contact with other intelligences: we could see what role, if any, religion plays in their development."
- Arthur C. Clarke

Positive Ray Propulsion (Ion Drive)  
  An ion drive.  

Very good and very early description of an ion drive system for propulsion.

Nine slender sunships lay at the side of the wide, high-fenced field, just in front of their sheds. In the brilliant morning sunlight they scintillated like nine huge octagonal ingots of polished silver.

These war-fliers of the Moon Patrol were eight-sided, about twenty feet in diameter and a hundred long. Built of steel and the new aluminum bronzes, with broad vision panels of heavy vitrolite, each carried sixteen huge positive ray tubes. These mammoth vacuum tubes, operated at enormous voltages from vitalium batteries, were little different in principle from the "canal ray" apparatus of some centuries before. Their "positive rays," or streams of atoms which had lost one or more electrons, served to drive the sunship by reaction—by the well-known principle of the rocket motor.

And the sixteen tubes mounted in twin rings about each vessel served equally well as weapons. When focused on a point, the impact-pressure of their rays equaled that of the projectile from an ancient cannon. Metal in the positive ray is heated to fusion, living matter carbonized and burned away. And the positive charge carried by the ray is sufficient to electrocute any living being in contact with it.

Also a good early example of what Larry Niven called the Kzinti lesson, namely, that "a reaction drive's efficiency as a weapon is in direct proportion to its efficiency as a drive."

Compare to the ion drive from Equalizer (1947), by Jack Williamson; this is the first use of the term in science fiction. Also, see the T.I.E. fighters from the Star Wars novelization by George Lucas. See also the use of finely divided dust as propellant from Earthlight (1955) by Arthur C. Clarke.
