not lighted matches, but i do eat fire
not intentionally, but i have set fire to my hair mid-performance and not realised until someone told me... it's on film somewhere as well
and not my clothes, but i do run fire along my arms / legs / chest / tongue for fun

anyway, back OT, i doubt you could make enough heat with minimal weight, why not do an electrically controlled flame? sort-of like a pilot and main burner system found in a boiler?
