Don't know why the original quote didn't print, nevertheless... There are more than one smokeless powders. The term refers to projectile propellants which emit little solid material in their exhaust. Nitrocellulose is one, but there are others, the names of which I forget. Look in Wikipedia for propellants, reaction efficiencies and other entries on high-energy compounds and you will find examples of 'smokeless' propellants.
