Disney Launches Fireworks With Compressed Air
rtphokie writes "When Disney debuted its new firework show at Disneyland recently, they also debuted some new technology which uses compressed air to lift fireworks. This virtually eliminates the need for smoke-producing black powder and other materials at launch, significantly reducing ground-level smoke, and apparently: 'Disney is in the process of donating all seven patents associated with the new air launch technology to a non-profit organization so these patents can be licensed to other pyrotechnic providers'. Something to think about for those of us attending fireworks shows this weekend in the U.S."
needs no puny patents to create an aerial light and sound extravaganza.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
What's the fun in fireworks if there's no boom when they're shot?
this takes all the entertainment out. like my mom used to say, its not fun and games until someone loses an eye.
I forget, are we supposed to like or dislike large entertainment corporations on Mondays?
Part of the whole fireworks experience for me, and I'm sure for others, is the bombarding of the senses: sight, sound, and even smell.
Fireworks with no gunpowder smell? With no black snow falling? I have so many memories of watching the fireworks over the lake in Epcot, the clouds of smoke only visible when the fireworks explode and light up the sky.
Sounds like something I could just watch on my computer or TV, if I wanted. I'll pass. It was bad enough that they had to take away Mr. Toad's Wild Ride, now they're robbing of me of smoke filled fireworks.
In other news, Disney has decided to release all of its old movies into the public domain. Says spokeman David Franz, "We realize that the DMCA and the Sonny Bono Copyright Extension Act were both mistakes that hurt the American public."
Disney apparently didn't get the memo about patents. They are supposed to hold onto them, write out thousands more of them in much more fuzzy terms, and then sue every person/company on the face of the earth if they have a one letter resemblence.
...how long it will be before you'll be able to buy one of those compressed air launchers at rest stops in South Carolina along route 95.
The release is very much lacking in details, but the concept is interesting. A friend of mine, a "licensed pyrotechnician," spent nearly three hours at our backyard launch (that rivaled any of the local shows) preparing powder and launch lines. The result was quite an investment in the firing equipment and materials; if the compressed air mechanism is really that efficient it will be reusable. Be clean and save money.
Start using the methods and devices commercially and you prevent them from being patented, everyone can use them freely.
Patent them and donate the patents to a non-profit, and you get a huge tax write off based on the assumed commercial value of the patents.
Disney isn't really doing anyone any favors here, they patent the common potato cannon and then donate the patents to a non-profit for the tax write off.
I've had enough abrasive sigs. Kittens are cute and fuzzy.
Leave it to Disney to severely edit yet another Asian product...
Small potatoes make the steak look bigger.
That blows.

Disney does something environmentally sensitive, by developing this technology and then DONATING it, and it gets run into the ground. Sigh.
The cloud that's created from launch turns into the color of the current firework going off. It just adds to the experience. So does the smell of the gunpowder. I guess that's why laser shows bore me.
I also hate the crowds at firework shows. That's another rant.
SCO launches new Linux Distro with Compressed Methane!
Posted by BREAL69 on Monday June 28, @1:06PM
From the ba-da-bing dept.
breal writes "When SCO deputed its new CD-Delivering service, they also deputed some new technology which uses compressed methane to launch CDs to potential customers. Darl McBride reports that it significantly reduces the cost of their distribution. We're able to use employees and users alike to deliver our product! SCO also says it has patented the technology, which they call "Gas on DEMAND" which they plan on donating the patents to many non-profit organizations.'"
Looks like something at SCO smells fishy again.

I work at Disneyland, and this is something that has been talked about quite a bit at work. I do crowd control for Fantasmic!, which also works during the fireworks to set up standing areas and keep walkways clear. The two reasons for using compressed air was, like the article said, to reduce smoke at launch, and to reduce the noise of them being launched. The former was achieved, but the latter seems to have turned for the worse. The fireworks do make quite a noise when they launch, but they seem to make an even louder 'boom' while bursting in the air. The residents in the surrounding neighborhoods have been complaining for years about the noise these fireworks produce, and the new series 'Disney's Imagine - A Fantasy In The Sky' was supposed to calm the burning tempers. It seems to have failed. Complaining about the fireworks at Disneyland is like complaining about living next to a railroad track. They were there when you moved in, so you must have known what you were getting yourself into. Oh, and by the way, the new firework show is quite lame. The music played has nothing to do with the fireworks that are going off, nor does it seem to 'fit in.' Okay, so maybe the music from the Lion King (The Circle Of Life) fits in, as they do launch circular fireworks, but who wants to see a hallow circle? Save your time and stress from the crowd by going to a traditional park on the 4th. It will be much more fun, I promise.
because rockets are only used by terrorists... ... that's why compressed air launch is necessary.
I know this is meant to be funny, but I would think anyone making a rocket propelled weapon wouldn't really care whether the propellent was black-powder based or air-based as long as it gets its payload to target.
Actually, the U.S. military has a preference for non-flamable launch/propellent technologies because it's safer for the troops who're fireing the rockets. Basically a flamable propellant adds little or nothing to the damage to the target, but if the ammo store is hit, it adds quite a lot to the destruction of the ammo store.

Disneyland builds/built a lot of their computer control equipment in house. My dad made a lot of it, including "Mickey's Match" - the original computer-based fireworks launch system that was programmable.
Before that, a man named Mickey (i'm not making this up, the guy's name was Mickey) physcially ran around and attempted (pretty well, from what i hear) and manually lit the fireworks to coincide with the music. Eventually, he started using electrically fired squibs. My dad's system allowed folks to pre-program sequences to launch with electrically fired squibs that would be in time with the music.
Since you didn't run to Fry's in the mid 80's to pick up a Pentium III to run Star Tours ride control (actually, Star Tours runs on a 486 for its ride control, with one redundant computer for each simulator), a ton of the hardware for ride control, gate counters, etc. have all be built by hand by the Disneyland Sound department and WED.
Many of the rides at Disneyland have my dad's name on the circuit boards in them.
Just about every system, even to this day - are Z80 based. Its simple, its cheap, and they are bulletproof.
Some of the Disneyland items he's made...
- Invented/installed the fireflys in Pirates of the Carribean
- Came up with putting the green-eyed rats at the end of Pirates as you go up back to ground level. We have a bunch of them at home and put them in windows and under the Christmas tree
- Invented the light flicker-ers that have been used at Dland for almost 30 years to make plain lightbulbs in opaque houseings look like they are flame
- Real-time population counter for Disneyland. Even went to the president's office and installed the LED display on his desk (prior to the popularization of "computer networks")
- Completed the transition of all of Disneyland's audio and attraction control tapes to solid-state ROMs for playback. They used to have rooms FULL of huge tape bins with 1" wide magtapes that would spool into a big 1" x 40" x 20" bins and be one big long lopp track - literally. This took a long time becuase back in the early 90's when they did it, they needed to send out the tapes to special subcontractors that could digitize it.
Its neet to see Disneyland, and how its starting to come back a bit after the 90's trashing by Eisner (ptooey!) now that he's been emasculated a bit. Things are getting better, and he's still making all kinds of neat stuff.
I need to get to Disneyland more often now.. i haven' been in years.. and i used to go 3 times a month when i was a kid.
guns kill people like spoons make Rosie O'Donnell fat.
We really need to streamline the patent, development and deployment process on this one and get these "boomless" fireworks into Iraq and Afghanistan so people can start celebrating their weddings again.
The big news is not in the compressed air:
Disney is in the process of donating all seven patents associated with the new air launch technology to a non-profit organization so these patents can be licensed to other pyrotechnic providers'.
Its nice to see a company using patents correctly, and donating them to an organization who oversees the pyrotechnic industry.
When I set up a show, I bring mortar racks, shells and a firing system. The press release was kind of sketchy but I'm assuming I would need to bring a high pressure compressor (a Home Depot 175PSI compressor is not gonna launch a 5Lb shell 1500 feet with any reasonable mortar length). I would also need hundreds of feet of high pressure tubing (A finale rack is at least 100 feet from the main guns), and lots of fast (read expensive) air solenoids. It would take forever to set up a show like that.
Then there is the safety problems, thy don't say how they ignite the time fuze and verify it's burning before a tubeload of rapidly decompressing, cooling air hits the shell. I would like to see some dud data.
For a recurring display where you can leave the equiptment and just drop shells in the same tubes every night or week, this sounds like a dream though. I just can't see it coming to a municipal 4th of july show near you any time soon though.
Finally! The technology I need for my X-Prize entry. Scaled Composites, look out!!

On a pedantic note, most aerial fireworks, at least in the US, are not rockets. They're fired from mortars, think cannons pointed up.
In case anyone is interested, here is the fireworks page from How Stuff Works.

It's all fun and games until someone loses the key to the handcuffs.
If they are using nitrogen, it's a non-issue.
From what I understand the fireworks are self-igniting based on input from some onboard logic so it's not like you have to worry about blowing them out - I'd use nitrogen gas.
Having self-igniting fireworks is potentially very cool, especially if you could get a nice cheap altimeter on a chip. If you coupled that with an accelerometer on a chip (analog devices makes a couple of different models) you could detect launch, free fall, terminal velocity, and make sure that the fireworks are over a certain altitude before firing.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Actually, they don't use anything to fire 1000 pound projectiles from the Iowa. She was decommissioned in 1990 after the accident in #2 turret and never repaird. She's been in San Francisco since then, and would require tens of millions of dollars in repairs to be considered battleworthy, probably including complete replacement of the damaged turret.
And the Iowa-class battleships had 16" guns, not 21", firing projectiles ranging from 1900 to 2700 pounds propelled by 550 to 650 pounds of powder. The largest deployed naval guns were on the Japanese Yamato-class battleships, and were 18.1" bore diameter.
They are impressive, though.
You can never go home again... but I guess you can shop there.
People like Mike Hiskey at Los Alamos have been contracted by Disney to make fireworks that are based on organic molecules, and use smaller amounts of chemical salts for the color. He also works on high-nitrogen explosives, along with several others working in the specialized field of novel explosives design and synthesis.
Strangly, not really true.
Although fire is a big risk, you are all (hopefully) shooting with the same gear on as a low-budget fire department, so the odds of you catching on fire are pretty slim. The entire time you are shooting (if it's a hand-fire), you are being rained on by burning embers (barring good winds)
It's the concussion of the charge that will get you. Whenever you are loading or handling fireworks, you always keep your back to an open area, so if something happens you get thrown away instead of thrown into something solid. The buildings that they build fireworks in will blow to pieces much easier than any normal building so that anyone inside doesn't get compressed by all that pesky expanding gas.
I've only done around a dozen shoots, and am not a licenced pyrotechnician, but on two of the shoots we have had misfires. One was one of my tubes on a hand-fire, and fortunately blew out the other side of the rack (it was my first shoot). The second misfire was on a finale so everyone was quite a ways away, we didn't even really realize what happened until we were cleaning up and found a 2-by-4 twenty yards or so away and a half of a rack with a pretty much destroyed tube. Fireworks are fun.
The Disney gatlin gun uses compressed air to launch shells in the 4 to 8 inch range. At least this was the sizes they launched a few years ago when I saw the system, maybe they they go up to 10 inch but Disney doesn't shoot many 12 inch shells anyway.
They have a large several hundred horsepower air compressor at each air launch system for the lifting oumph. No nitrogen involved as it is too expensive to use in the quantities required.
The shells are plastic encased shells that are a little enlongated (not sperical like normal shells, think eggish). Inside each shell is a little electronic circuit and electric match. The circuit is engergized by a inductive coil in the base of the fiberglass launch tube. The circuit doesn't use altitude per se but a timed interval instructed in the coding pulse at the launch event.
The bulk of the show will still be fired normally as they have lots of ground level effects and lots of smaller shells that would be too numerous to fire in the air launch system unless they have made great strides in its firing rate. I shot many a show that had 100 of 3 and 4 inch shells going up per second.
Still plenty of smoke to be smelled around the lake in Epcot.
