What type of camping stove can burn anything? - meths stove

I know it is a kind of stove that can do almost everything (vodka, denatured alcohol, gasoline, burn more). I know he has a bomb in the computer and the other side of the tank is the filler cap. Looks like a stove with two fuels, but that does not seem to be able to burn both fuels. Am I wrong?
