Essentially, this sounds like a rail gun. 

Taken to a much larger scale, such devices are capable of projecting small 
aluminum or heavier metal slugs at speeds capable of reaching thousands of 
miles per hour (in theory sufficient to place small objects into low earth 
orbit).

Ignore the G-forces on launch and the atmospheric frictional heating on the 
launched objects.  Also never mind the fact that they take megawatts of 
electrical power to do so... they are possible.
