Flag made entirely of flames

  [vote for,

So, it seems that burning flags are a popular thing here on the HB. Ever heedful of market demand, we at MaxCo. have developed a range of flags made entirely of flame.

The most basic product is the French flag. It consists of a flagpole concealing several gas lines, and a horizontal bar sticking out from the top, to create an inverted L. The horizontal bar carries a series of nozzles along its length, each directed upwards. A small igniter sits at the mouth of each nozzle

Using volatile metal-containing additives in the various gas streams, the FFMEOF creates vertical jets of flame in red, white and blue that resemble closely, look a bit like, or are vaguely reminiscent of (depending on how close you are) the French flag.

The Union Jack version (henceforth known as the UJMEOF) is a somewhat trickier piece of engineering, requiring as it does a complex series of red, white and blue flames that emerge from a central hub and radiate outwards to achieve the desired effect.

Sadly, development of the USFMEOF is proving technically challenging. And plans for a WFMEOF have been put on hold.

       However it's done flaming flags should be a thing.   

       Explody flags are already popular. (link)

       You may like John Gerrard's artwork - link. (his sister Joy Gerrard is also a very good artist - painter)

       Hmm. The John Gerrard video looks like it's been manipulated - the smoke is dense up to a point, then it just sort of vanishes.

       Time to do it with my "sculptured fireworks idea" where everything is shooting out attached to a pre-measured tether that triggers the explosion when it's at the end of the tether.   

       That's the one where you can actually get 3d fireworks displays.

       Cool link B.

       //The John Gerrard video looks like it's been manipulated// The entire image is virtual. It's a stunning work, acheived in ultra high resolution like all of his pieces. You should look him up if you want to know more.

[MaxwellBuchanan], I thought you would be cleverer than than...
You simply need a set of high-speed additive dosing units at each flame, to change the colour as it goes up. Spatial resolution will be approximate, but you should be able to get it good enough for most flags (some annoying places have extremely detailed flags, so, sucks for them...).

       [+] Obviously.   

       I've spotted a mistake within the idea. The FFMEOF seems overcomplicated. I feel the international community would more readily associate France with full-width titanium/magnesium, perhaps with a vague sodium streak running through.   

       For the UJMEOF* getting the shades exactly right might be tricky but within our grasp, I think.   

       The various colors produced by burning metals show that reds whites and blues are all possible. Sadly, I often see red Lithium/Strontium burning in blueish butane flames which gives a purpley hue, obviously unacceptable. Alcohol would seem the solution since it burns almost invisibly. Within that is an opportunity, the alcohol in question could be a mix of fine English gins, outstanding Scotch and Norn Iron whiskeys and something Welsh**. This should be mandatory at all flag displays so that winning a medal in the 2112 Nanjing Olympics forces the hosts to shell out on expensively acquired*** imported booze.   

       To catch counterfeiters, careful spectral analysis of the UJMEOF should be routinely performed. Attention should be paid to both the visible and invisible light spectra, in fact, a further opportunity exists, you could encode the UJMEOF in infrared by tweaking the C/H ratios and flame temperatures.   

       Once you have your UJMEOF encoded in the invisible region of the EM spectrum, you can omit the visible. This might be useful for military purposes where thermal imaging makes traditional flags tough to discern. The FFMEOF would likely not require such features since invisibility is its defining characteristic within the combat theatre.   

       I was happy to see that the Union Jack constitutes a whole CATEGORY of flag types [link].   

       * A nickname of course, more correctly it's the UFMEOF. ** leek and daffodil liquor? Distilled sheep pressings? Whatever represents the best alcohol/price ratio? *** Supply/demand might lead to price surges during/between Olympic years.

       //The FFMEOF ...full-width titanium/magnesium, perhaps with a vague sodium streak running through.//   

       I was sort of counting on [8th] to make that particular suggestion.   

       //I thought you would be cleverer than that// That's odd - I thought I'd be cleverer too. Funny old world.

       Flame throwers should be incorporated somehow.
