Yes. Wax. It contains enough energy to cook or heat with, just the same a kerosene. Folks will almost immediate say - wax is no good - too much soot. Yes, if you have tried a "Brownie burner" (named after the GSA branch - Brownies) - like this: soot is a real problem. But using a wax gasifier stove results in a clean burn and little to no soot. Carry that a bit further and see a commercial wax gasifier stove in action, and you see no soot. Yes, such a thing is offered commercially - by an outfit called GAT Energy. (ARK STOVE Portable Stove Fueled with Wax) They use pellet wax, but any wax will work. This is the stove stove with oven - will bake at 200F to 500F - just like Mom's gas oven - only a bit smaller. Wax has some advantages over other liquid - no water vapor while burning for one. This post is just a head's up, go to the GATT site if you want to learn more. Enjoy.
