As any wick operating lantern, Electrophorus works on kerosene or liquid wax. Operating the Thermo Lamp outdoors, the fuel quality is of minor importance. On he contrary, when the operation happens indoors and especially in closed rooms (that is not advised) only the best quality is recommended.
Various brands have been tried, and following gave me the most satisfactory results in those prototypes. The list is just indicative and not limiting since I cannot test every brand of fuel in market .
Liquid wax: Sterno liquid wax lamp oil, Lamplight Ultra-pure clear Lamp oil etc
Liquid wax, is more viscous, less volatile lamp fuel. During warm up / shutting down , the minimal fuel odor emitted is not offensive and well tolerated,
Wicks less than kerosene, flame luminosity is marginal, freezes below 20 degrees Fahrenheit (-6 Celsius).
Kerosene: Aladdin genuine lamp oil, Kleen-Heat etc
Less viscous, higher volatile fuel, flame can output like 40-50 lumens (+plus)
The minimal kerosene vapors emitted during firing up / shutting down, could be offensive to some
Fuels consumption and generator output is practically the same.
Personally, for effect, i go with kerosene, while my wife is around i go with paraffin.
