You might be into the realm of small theatrical equipment.

Roger,
You might try an oil lamp with diesel/old motor oil.  Or a tank with a heavy
wick similar to an oil lamp.

If you can't find a ready made unit, I'd buy a bottle of theatrical "fog
juice"
and experiment with a heater of your own design. Here's a page that might
give you some ideas (though it's not suitable for a model boat since it uses
a salvaged electric iron):

Someone in another thread suggested the element from a 12 V soldering iron
as a possible heat source. A ceramic power resistor might be another option.
They can be driven pretty hot without damage, and the fog fluid will carry
of
a lot of heat in any case. (One advantage to a power resistor is you have a
wide choice of values so you can tailor it to your needs.)

The site above also suggests an ultrasonic atomizer as a alternative. It
might
be adequate to your needs and it would have several advantages: It would
be clean, definitely non-toxic, and wouldn't use nearly as much current as
a heating element. (Fog juice is relatively non-toxic, but kinda oily and it
does smell.) You can buy the atomizer units new from fountain supply
places on line. -Wm
