A light gas gun is basically a giant springer in which the piston is driven by a pyrotechnic charge and the gas in the chamber is hydrogen or helium.  I don’t understand all the physics, but lighter gases are able to transfer more energy to the projectile.  Some people have reported small but measurable increases in muzzle energy after filling their PCPs with helium.  https://en.wikipedia.org/wiki/Light-gas_gun

One thing to keep in mind if anyone is actually thinking about doing this: hunting regulations for big game may specifically require a PCP in order to allow quick follow-up shots for humane kills and hunter safety.  Arizona is like that.
