Do you mean from way back when they use to use Flash powder on a pan of sorts and ignite it at picture time (while the shutter was kept open)?

No. I see it used as an expression I think.
Some kind of secret interwebz lingo that old farts like me ain't sposed to have privy to.
I saw someone refer to their 2.1mp digital as "coal fired".
Also, my prized, newfangled AF240Z is supposedly "coal fired".

Sounds like just a figure of speech, though I haven't heard it before, myself.

It stands for "old stuff" that the snot-nosed youngsters do not appreciate.

Probably implying that the device in question is so obsolete it belongs in the age of steam when all manner of machines were powered or heated by coal fired boilers.

I thought so.

Anyone know who coined the phrase?

"Coal Fired" is probably associated with old technology since many things that were powered by coal "directly" are now powered by other means.

eg domestic heating/cooking and steam trains used to be with coal.

interesting that these are now mostle electric but where does the power come from?
In Australia it is mostly Coal-Fired powerstations. I think in the US it is about 1/2 Coal Power.


If you tried to used pulverised Coal in one of those antique powder photography flashes I guess you would get a lot of smoke and smell but not much white light.
Flash powder is finely ground Magnesium (or even Aluminium) powder with Potassium Nitrate powder.
It burns very rapidly because of the high surface area of the fine powder and emits the bright white light for the flash.
It seems damn inconvienient to use and probably difficult to get right.

Not to mention probably on the Homeland security watch list anyway

So my 1.1mpx Sony DSC-P20 from 2001 is likely coal-fired, not to mention a few dozen film cameras, F-series (and older) lenses, non-digital phones, cassette and minidisk decks, pre-Macbook computers, appliances lacking microprocessors, etc. Or maybe the pre-digital stuff is wood-fired. As am I.

I believe that pretty much covers it.
P.S. Nice to have a fun thread.

Obsolete:
Every new product is obsolete before it ever leaves the factory floor. Progress moves fast, alas. But even old stuff works. Sometimes.

Wood-fired:
I've rethought this, and I realize that I am dung-fired, like traditional SouthWestern pottery. That explains the smell, too. No excuses.

Not quite....it can be used to accurately reflect modern technology.... For an example, the D7000 is coal fired as compared to the K-5.
