Thanks all for the info. Some experimentation called for methinks.

Hi Yab,
The brand is "Costranica" and they can be found on Etsy. ( I have no connection with them other than purchases occasionally.)
They have a few different configurations and appliances, the most of which we wouldn't use, but some of the "hardware" as in the 90* tubing holder prevents kinks in the tubing but allows the unit to be placed remotely and the tubing run to the outlet. I didn't have room for the whole unit (including the batt compartment in one build), so pulled the wires from the compartment, cut it off the "business end" of the unit and hooked the wires to a switched buck converter set to 4.5V which lessened the volume that was much more consistent with the boat it was installed in.

Interesting to compare the different smoke effects. The fog machine produces lighter 'smoke' that appears to rise naturally, whereas the water vapour provided by a nebulizer is naturally heavy and tends to sink more rapidly. Is the fog fluid expensive and readily available? Any further details?

I'm a little late in this discussion, but have read the thread and no one mentioned the Cosplay Actor's fog machines.
These are pocket held little devices operating on four AA batteries which are contained within the device. Obviously they use heat to create the "fog", but it's not so hot it can't be hidden in a jacket pocket.
A real plus for them is they can push the fog down three feet of plastic hose and not loose any volume. This translates to remote mounting and not needing to be mounted under the stack. They operate in any position, and can be controlled by an ESC so long as their voltage remains under 6V. I don't operate mine all the time hence a channel activated switch to turn them on and off in short usage periods.
There are two in my tug, one for the main stack and one for Maude's cook stove. The one for Maude's stove has a drop of cinnamon roll baking essence (a candle making essence,) so if we're on the pond and an observer gets a whiff of it they're not offended.
In the video the air was stock still, but on the pond the slightest air makes the smoke more realistic.

LewZ;
you are a great detective.

I can attest that Yabbie's smoke generator puts out an impressive amount of "smoke" that is visable even in bright sunny conditions.

Cheers,
Stephen.

Liar, liar, pants on fire!

I got the vapor mister (in the video I recently posted) from Amazon. The mist is barely visible indoors, not even about 10% of that burst of "smoke" seen in the video.

So, I will give it a very bad review for a deciptive ad. However, I plan to keep it for the upcoming "Florida" hot summer days for which it should work.
