| Definition | a kind of spaceship drive |
| OED requirements | antedating 1976 |
| Earliest cite | Larry Niven, 'The Words of Science Fiction' |
| Comment | Malcolm Farmer submitted a cite from a 1990 reprint of Poul Anderson's "The Boat of a Million Years". We would like to check the 1989 first edition. Scott Neugroschl suggested Heinlein's "Time for The Stars" as a possible
source; Douglas Winston's reading of this found cites for "torch", but not "torch drive". Ralf Brown submitted a 1976 cite from an article by Larry Niven, "The Words in Science Fiction"
We would like cites of any date from other sources. |
