An incinerating toilet would maybe more effective as the oder is supposed to be less and the weight would only be ashes. I'd worry about the whole thing, camper included, going up in smoke and ashes too. Think someone someday will come up with something real tricky as a light weight, sanitary, more asthetecally appealing solution to human waste handling but till then I'll have to sick with the stinky slinky and empty ASAP routine.
