2114: "Launch Conditions"

OK, someone needs to make this humidifier a reality, because I NEEDS IT.

(I used to have an ultrasonic-type humidifier that looked like a dragon, but (1) the "smoke" didn't come out of its nostrils, and (2) like all ultrasonic humidifiers, it died after a fairly short time.)

The humidifier will need a place for dry ice or something else for cooling so the humid air will form a fog that hugs the floor, or other "launch" surface.

If you use some sort of refrigeration system, you can even dump the excess heat into the water reservoir to make it evaporate more easily. (seems like there should be a better word than evaporate, especially for non-steam humidification, but I can't think of it)

This needs to exist.

Ultrasonic humidifiers tend to do this without any extraneous intervention. In fact, they tend to have nozzles specifically aimed upwards to counteract this tendency.

A better word than "evaporate" would be "suspend", since this kind of non-steam humidification generates water droplets small enough to be suspended by air. But I don't think I've ever really heard "suspend" used that way.

Anyway, I have a feeling that even with steam humidification you get to an equilibrium state with micro-droplets pretty quickly.

"Atomize"? The sort of small droplet generation the ultrasonics engage in seems fairly similar to that historically performed by various misnomer'd things called atomizers, I think.

I propose 'dialesce', as the opposite of coalesce.

According to https://interestingengineering.com/nasa ... -exploding the water amount used is around one 50 m Olympic swimming pool per minute (according to my Back-of-the-envelope calculation). Trying downscale this to Ponytail's humidifier (factor 300 in all three dimensions?), it looks like this humidifier should produce 1,5 liter water steam (droplets?) per minute. In an hour or so ...

( olympic pool/minute) * (300)^-3 =

(2,500,000 L/minute) / (27,000,000) =

0.104 liters per minute.

Such a humidifier (or any humidifier producing visible fog really) would need to run intermittently and would leave the countertop wet when it runs.
The thing about recursion problems is that they tend to contain other recursion problems.

Pshaw! Small price to pay vs. coolness factor. .

I already have an ultrasonic humidifier but I need this.

And yes, it would wet the counter... unless the vapor came out of a model flame trench!
