What's that black dust in monitors?

Very common in and near Philadelphia!

Completely irrelevant. You have to explain how monitors
used here in houses with only electrical heating and cooking
get that jet black soot on all areas adjacent to the FBT.

Thats the EVIDENCE that it cant be coming
from the oil heater combustion products.

Basic logic.

The brown color is mainly from nitrogen dioxide,

Its more complicated than that. Its mostly brown because
of the particle size. You get brown even from just dust.

which is usually the 3rd worst pollutant in the
Philadelphia area in terms of health even though
it colors the air more than soot and ozone do.

You dont get much jet black soot in the air,
even when everyone is using wood heating.
You get a very grey haze instead.

Tried web searching... Looks like you're right on that one, and cobwebs
made solely of dust was something that I heard incorrectly before.

Yeah, you can certainly get dust sticking to what
are very light colored, almost transparent webs.

My cobwebs are definitely at least part dust and are usually
very dark in color, much darker than most of the dust in my home.

I dont get that at all. Not at all clear why mine are much lighter than yours.

The darkest mine ever get is a light grey, particularly when its
been rolled up. Mostly they are a buff/beige/light brown color.

I said you were a fool first - so there!

My entire point was that IDIOTS like you that go 'round calling
others "fool" are the true fools. Ever gander in your bible where the
lord says "Never say 'thou fool'". ??? Huh, you dipshit?

Actually, it's Tooth-fairy droppings. Not many people know this, because
most people think tooth-fairies are large. This is easy to believe if you
think that each tooth is removed by only one tooth-fairy, but in fact it
takes a multitude of tiny tooth-fairies to take away each tooth and a
similar multitude to replace it with cash. Before computers, the
tooth-fairies used to live in the fireplace, ever vigilant for gap-toothed
ankle-biters, and their droppings coated the inside of chimneys. Now they
prefer to live in the warm seclusion of monitors. By the way, it will be
pointless to peer into the monitor looking for the fairies: just as no-one
has ever seen tooth-fairies actually removing a tooth, so no-one will ever
see them inside the monitor. Trust me.

Hahahahah... I like it.

However, if no one can see them, how do YOU know that it's twoo?

Huge zipping sound...

It's Twoo! It's TWOO!

I just tried adding some water to some ordinary dust and rubbing it
with my fingers. It got darker, but not jet black like the dust in TV
sets. I think some kinds of dust particles are more atracted to the high
voltage points in TV sets than other kinds are.

Either that, or it gets carburized by the corona.

I do know for a fact that Flyback xformers do NOT exhibit
particulate... just volts.

WHatever the "TYPE" of dust, it certainly is sourced externally. My
monitor here right in front of me is that way... even on the exterior,
in the area of the anode supply hardware.

It is VERY dusty in this reclaimed dessert portion of California.
Ny monitors and the PCs have to be cleaned often. The monitor, once a
year, and the PCs 4 or more times a year. All since I moved out here
from the more coastal area I was at.

The idiot that thinks his FBT gives off "black soot" is merely an
abject idiot, nothing more.

PS. I don't own a copy of the bible. Anyway, I know how it

WOW! You are a true expert! N O T !!!

It's a mote in your eye, you fucking clueless retard.

The word is MOOT, dumbshit.

Seems to be too much particulate matter flying around on this thread !

Said the person that just contributed some of it.

I see enough air that is fairly transparent but brownish. That's when
nitrogen dioxide is a more significant factor than dust particles large
enough to easily scatter light when isolated.

Wood makes gray haze from larger tarry particles and ash, diesel makes
realy fine soot - maybe mostly in particles less than half a wavelength
wide, which don't easily scatter light. And maybe the fine soot particles
don't scatter much light because they are black.

Yeah, stands out like dogs balls when you fly into Sydney
in the right weather conditions. Its got the right conditions
for that sort of smog buildup and that brown haze is
utterly obscene in the right weather conditions.

dust particles large enough to easily scatter light when isolated.

Nope, it isnt mostly NOx

And you get a completely different effect when there is a bushfire
problem, completely different color, pale grey instead, tho you can
get some very spectacular visual effects at sunset in that situation.
That sunset effect is the evidence that its not primarily a NOx effect.

Its the same effect that makes the sky blue.

Wood makes gray haze from larger tarry particles and ash,

It hasnt got anything to do with ash at all, its just what makes smoke
grey. And that varys dramatically with the wetness of the wood.

diesel makes realy fine soot

Yes, but you dont get much of that rising to any great extent.

- maybe mostly in particles less than half a
wavelength wide, which don't easily scatter light.

Thats utterly mangling the light scatter effect too.

And maybe the fine soot particles don't
scatter much light because they are black.

Scatter has nothing to do with the color, its a size effect.

Ahhh... so now we know that this twit goes 'round looking at dogs'
balls.

I see similar brownish but transparent air flowing out of some
thunderstorms when I ride airplanes.

Are you claiming that these fine particles don't go where air goes and
where other smoke particles go?

It aint NOx. That never get to anything like a high
enough density in the atmosphere for it to be that.

Yep, they're considerably bigger and fall rather than rise.
And they dont have the same hot air driving them either.

Have a look at a really badly setup diesel engine thats pouring
out lots of the black stuff some time and see where it goes.

Diesels pollute less than gasoline fueled engines. Doh!

Not ll of the black particulate "falls" either. Doh!

You don't know "bad" from "rich". Many truckers set up rich for
heavy loads. Another item that I am certain you are clueless about as
indicated by your "the FBT is putting it out" stupidity.

 

[Rod Speed]

Depends entirely on the specific pollution you are talking
about. Gasoline engines dont normally produce anything
like the same level of that black stuff being discussed
there as a very badly setup diesel engine.

Reams of your puerile shit flushed where it belongs.

It aint NOx. That never get to anything like a high
enough density in the atmosphere for it to be that.

A layer of air 4 miles thick with 1 PPM NO2 has light going through as
much NO2 as it would going through a 1/4-inch layer of pure NO2, which is
quite brown. I have seen an ampoule of the stuff before. A 1
inch thick layer of pure NO2 (some of it becomes N204 when that
concentrated, a molecule of which is basicaly just two NO2 molecules stuck
together more than being a different compound) is a rather dark brown,
although still lighter than a Budweiser bottle. The stuff looks like
bromine vapor. You can make visible quantities of nitrogen dioxide in a
small glass jar if you put in that jar a spark gap with a capacitor of
about a nanofarad across it and power the spark gap with a neon sign
transformer. You may need to adjust the spark gap or try a larger
capacitor (with power off!) if instead of a loud bright series of sparks
you get an arc. Beware that a neon sign transformer with a capacitor
across its secondary can resonate and the voltage may get high enough to
cause destructive sparking in the transformer unless the spark gap is
short enough to limit the voltage to a value safe for the transformer's
insulation.
Unhealthful air quality based on average concentration of the worst hour
is .3 PPM of NOx, and that is mostly NO2, and that seems like enough to be
visibly brownish in a layer just a few miles thick.

And how about ones in not-so-bad tune that make finer soot? I see
enough blackish smoke from diesel trucks rising and flowing with air
currents. Sometimes it looks bluish when illuminated by sunlight, so some
of that soot has to be of particles of size around a wavelength or
somewhat smaller, and particles that size don't fall out of the air faster
than the gray stuff from wood fires.

You dont get that 'flowing out of some thunderstorms'

with 1 PPM NO2 has light going through as much NO2
as it would going through a 1/4-inch layer of pure NO2,

Pity it doesnt end up brown at all at that concentration.

which is quite brown.

Yes, but not at 1 PPM it aint, even thru 4 miles of it.

I have seen an ampoule of the stuff before.

Irrelevant to what air with 1 PPM looks like.

A 1 inch thick layer of pure NO2 (some of it becomes N204 when
that concentrated, a molecule of which is basicaly just two NO2
molecules stuck together more than being a different compound)

Thats utterly mangled too.

And at 1 PPM it aint even visible.

Taint relevant to whether 1 PPM is visible. It aint.

across its secondary can resonate and the voltage may get high

All completely irrelevant to the visibility of 1 PPM.

Nope, fraid not.

Dont believe it.

so some of that soot has to be of particles of size
around a wavelength or somewhat smaller,

Thats just smoke, not the jet black soot being discussed.

and particles that size don't fall out of the
air faster than the gray stuff from wood fires.

Pity it aint the jet black soot being discussed.

More immature baby bullshit from the twit that couldn't approach
light speed with a light speed rail gun, much less exceed it with the
"worldly" bullshit you bring to the table of life.

Again, dipshit... They are NOT "badly set up". They are set up rich
for a reason. Get a clue. And NO, they do not pollute more.

YOU were badly setup, however.
