Yup. And the concept goes way back in southeast Asia (IIRC).
As to the cotton balls & vaseline, that's one way. Another that our scout troop uses is to put some dryer lint in the pockets of an egg carton (the cardboard type), then pour melted used crayons on them. They'll start ANY fire, any time, even in the rain. They burn forever, too, and are relatively small and lightweight. Plus, they're waterproof, so they don't need special storage.
