i've often wondered at the feasibility of building something that uses a miniature blowtorch at the end of firearm device that fires and ignites, say, .40 cal projectiles inside of a gelatin shell filled with flammable material like white phosphorous. you'd have to use some sort of compressed air to launch the capsule, i don't know if co2 would be viable as the compressed air, as it could flame out the blowtorch igniter at the end, but i just never thought the whole idea of firing compressed flammable pellets that ignite to cause fire damage as being viable. surely someone would have already created it if it was. the applications of such a device would extend far beyond just lighting people on fire, include some magnesium powder in the gel capsule mix and you could light pretty much anything on fire. it also seems it would be fairly short range, like a paintball gun. meh, i feel that my limited knowledge would be far more likely to explode me trying to build it than the purpose i intend it for. not worth it.
