- The questions about the military use of railguns is quite appropriate.
- One of the first SF book to include the idea of a railgun--or magnetic
- catapult, as it is called--was Heinlein's "The Moon is a Harsh Mistress"
- Among the concepts proposed there was the military use of a railgun
- from the moon; the rebels who sought to throw off Earth domination
- of the moon in the novel used large rocks encased in steel canisters
- as a weapon. When "thrown" from the catapult, these masses of rocks
- would gain speed as they sped down Earth's gravity well; the velocities
- they reached meant that on impact on Earth they had the blast potential
- of a small nuclear weapon.
- This idea was later picked up by the SDI--Star Wars--bunch and called
- a "mass driver". So the military potentials of a railgun are quite
- possible. Makes one wonder why the govt. is so hot on getting back to
- the moon . . .
-
- p.s. This is a neat thread, but it should be moved to the SF or science
- newsgroups.
