Science Project gone WMD

[Spee]

I once read on a site that there was a method of creating a railgun. A very weak, very limited-in-scope railgun, but a railgun nontheless.

It consisted of 1 iron ball bearing, 1 magnet, 2BB's, 1 magnet, 2 BB's, 1 magnet, 2 BB's, 1 magnet, 1 BB. According to the formula presented there, the force put into the first magnet is multiplied through the amount of magnets, using some crazyass form of conductivity.


Thus, if 1 lbs of pressure were put into this system, which had 4 magnets, 1 lb would be multiplied to 2, then to 4, then to 6, resulting in the final ball bearing being propelled at 6 pounds of pressure.

The reason it hasnt been implemented in military projects, Id assume, is because of the length needed to obtain good muzzle velocity, and the method of reloading.

But, barring that, would it not be feasible to extrapolate this to a sort of giant orbital cannon? a 2.5 mile long structure in space, with say, the final "ball bearing" being a 3' long iron pole, would result in rediculous devastation, would it not? Or, did all thisdirty talk of a rail gun give me an evil genius hard-on?

Science majors, tear me apart.
