High rise sky writing smoke jet printer

Write your business name across the sky

Sky writing is pretty cool. I've never understood how the pilot manages to join up his 'o's - or how he knows where to start the next letter.

My idea will obviate the needs for specially trained (and expensive) pilots. It works sort of like an ink jet printer. Except instead of ink being shot on to a page of paper it shoots smoke up in to the air. The print head is mounted on top of a high rise building, and instead of the print head moving it relies on wind to move the 'paper' to the side.

Of course, you'd have to measure the wind speed and print faster on blustery days. On calm days you might just get a message that reads 'mmmfff'. Someone would have to come up with glow in the dark smoke for night times, and water proof smoke for rainy days. Coloured smoke would help on overcast days too.

A form of this is done by airplanes. Nifty idea to put it on a roof [+] [Sunstone, Jan 28 2013]


       +, but, 'water proof smoke'?

       (+) I like the idea. What about some drone balloon?   

       I think that any sort of wind near to ground level would dissolve your message pretty quickly as air mixes around a lot near the ground, I`m sure.   

       A balloon could write in three d even on the stillest of days.

       For the Vatican - "Habemus Papem" [+] - it would save trying to decide if the smoke was black or white.

       The AOL scyscraper could write "AOL" in the air, and the building next door could puff out "Sucks" right behind it :)   

       Then, when it rained, the smoke would somehow combine with the air and water to rain down AOL CD's.

       I imagine you'd have to use some seriously toxic smoke in order to make this work. therefore:[+].

       You have the backwards. Since the wind is scrolling it, the "sucks" building would have to print before the "AOL was printed.

       Maybe a grid of balloons, filled with RGB smoke. Then use a huge shotgun to pop them all at the same time...
