hmmm I wonder if lightbulb filaments would work???
I know you've joking, but just for the laugh...
100 watts at 100 volts means 100 ohms, and I have a feeling that it is significantly higher when the filament is not white-hot.
A brake-light is about 30 watts at 12 volts making 4 ohms, and the only available tungsten headlight bulbs are only 45W. At 6V (8 or 11W) that might be marginally useable.
Flashlight bulbs are the right voltage, but less than 1 amp.
If you looked hard enough you might be able to find one that worked, but they are generally too high resistance to be any use in an atomiser. And of course it is probably too fragile to rewick.
