   It's one you haven't seen before.  That episode is at least a year old,   
   probably three or four.

   The steam machine gun used steam not to propel the bullets themselves,   
   but rather to power a centrifuge that whipped the bullets out much like   
   a sling (a real one, not the elastic cord between two posts variety).   
   As I recall, they determined that its effective range wasn't all that   
   great.
