Survival Balloon? - 02/13/06 08:21 PM

This is an article from the mpioutdoors website. Is this info on the level or is the author dreaming? This is the first time I have ever heard of a balloon as survival equipment.

SURVIVAL BALLOON?

www.mpioutdoors.com/baloon.htm

Something that can be a very useful addition to your Personal Outdoor Safety Kit is a simple balloon. Several sizes of balloons can be easily purchases at gift stores and craft shops around the country, for less that a 25 cents each. Look for good strong latex ones. There are a wide assortment of ways in which this product can be successfully and strategically used in the outdoors for your comfort, protection and personal safety. Here are some of the uses, there are most likely more:


an emergency water carrier-- fill the balloon with water from a steam by partially inflating as you pour into it, takes some practice but it can be done. Tie off the opening with a cord for easy access, transport by supporting the balloon wrapped in a shirt or jacket.
emergency tourniquet—in the event of a deep cut or to stop bleeding when trying to extract a fishing hook, wrap the balloon in deflated stage around your finger, arm or leg and twist to apply pressure to temporarily restrict blood flow. Do not restrict flow for long periods of time.
lashing poles for a shelter— in an emergency situation you can wrap a balloon around the top of 3 cut poles in an upright position then spread the poles into an open position to form a triangle structure. Dig in, tie or stake down your frame. Cover your structure with a SPACE® Brand BLANKET or extra clothing, pine boughs, etc. for temporary protection from the elements.
emergency splint—wrap balloon around cut branches to help immobilize the break. Stretch balloon to tighten around the makeshift splint. Get medical help as soon as possible.
rifle barrel cover—in wet and muddy conditions a balloon over your rifle barrel will keep out the dirt and grime. You can shoot through it if it becomes necessary.
cushioning—when traversing over rocky terrain or in white water, inflate balloons part way to add cushioning to your camera or other valuables in a backpack or wet bag.
pillow—inflate to desired comfort level, cover with shirt or jacket for added comfort.
back support—in a tree stand, or sitting waiting for that turkey, inflate balloon and position in the small of your back against tree. Do not over inflate, allow for comfort.
lashing--tie together your gear and affix to backpack, lash fishing poles together for travel, etc.
tent tie down—got a torn tent flap closure or a tie down rope, twist the balloon and use it as a temporary fix. No string use it to wrap around a branch to support your lantern, etc.
fix broken straps—the flap on your backpack, the catch on your fishing tackle box, whatever.
emergency ice pack—if available add ice, if not fill with cold water from stream. Do not try and use it as a hot water bottle in your sleeping bag, or the midnight fire brigade will arrive.
trail marker—shred into strips to mark the trail you just traversed, or make like Hansel and Gretel and find your way back to your camp after a trek into the wilderness.
tie off—take 4 balloons and tightly wrap around and over each end of a SPACE® Brand EMERGENCY BLANKET, tie front two off onto positioned upright poles and then stretch the back tow down and secure to form an emergency lean to. Face opening out of wind and towards fire for shelter.
food storage—for an emergency situation, before you leave take a balloon and stuff it with trail mix, dry cereal etc. When your hungry a little extra nourishment can go a long way.
marker buoy—found a great fishing spot, mark it with a balloon and string tied to a rock.
some uses that require a little stretch!! Makeshift predator call - emergency shoelaces - Fishing bobber - Hand mitten for keeping off blood while cleaning game or in case of sheer boredom a slow motion volleyball game can be quickly arranged!
All of the above may seem a little silly and inane, but by taking a simple object and finding uses for it that can be beneficial in your outdoors adventures is a mind exercise of visualizing your environment and your potential needs. In the outdoors your mind is your greatest survival tool, going through an exercise like the above may seem like a bit of fun, but it can be very beneficial, as it keeps you thinking. Should you ever become lost, stranded or separated, you will need to have your mind working for you and not against you.

When I get a balloon, I will try some of these ideas. Comments?

Why not? Seems reasonable to me. Probably a good idea to have more than a few on hand if you intend to use for all of those. :-)

And definitely, strength of material has to be the number one issue on most if not all of these. Though, I have seen some cheapo party baloons survive crazy things I wouldn't have thought they could. Might just have to add one or two to the PSK.

So....just how long does it take to fill a balloon with granola? Do I hear "condoms filled with granola".....?

I think I'll buy a bag of balloons...... If you connect them all over your body (including your toes), I'm sure the masses will not mess with you as you Bug Out.

Another use towards Survival which immeadiately comes to mind, -is it's use for getting a GPS, Radio Transmitter / Receiver, Small Observation Camera, Signaling Device, etc, -up above Trees, Hillsides, etc, -to a working Height.

Also, -larger ones for Escaping, Clearing Heights, Obstacles, etc. (As exemplified in some Famous Escapes over the Berlin Wall and Iron Curtain.). Might be as good way to Clear a Glacial Crevice too!

Along the above lines, -I once heard something about some kind of personal "Jumping Balloons"! If anyone knows anything on them, -I Sure would like to so Know too!

I've also mulled over the Possibilities for using Balloons for (seeming) "Weight Reduction" in Gear.

Problems here are that, if even Feasable, -it can be Great for some Terrains, -but not for others. For instance, -a Flat, Treeless Plain, vs Maneauvering thru the Trees and Brush of a typical Forest or Woods. And the Size of the Balloon for "Gear Weight Reduction" purposes, -would have to be not so great in Volume, -as to inhibit such Maneauverability.

To be Clear: -By "Seeming Weight Reduction", -I mean that X amount of a Balloon's Lift, -would cancel out X amount of Gear Weight. Making for certainly a Lighter Hiking Experience!

Together with the Many Uses that you have come up with, -Balloons toward Survival and Outdoors Purposes, -I think is not So Puff Up an Idea after all! [color:"black"] [/color] [email]riedmur[/email]

Re: Survival Balloon? - 02/13/06 11:35 PM

I've actually just recently done fairly extensive research on weather balloon technology for lofting wireless gear and I can tell you that the "lift" capacity of a standard 3' weather baloon is marginal under the best of circumstances (same for 6' and 18' which go up in cubic volume eponentially). If you attach some sort of lift generating structure such as wings and tail (ala assisted kite/ballloon hybrid "Platform") then you can get decent capacity of lift if the wind is blowing. But we are talking ounces. And the larger a ballon gets the more helium or other LTA gas is used and price goes up.

Now, in a field expedient sort of way, the ONLY rational use I could think of to carry a cylinder of Helium and a few weather baloons would be for signaling. And even then, you really need an anchor of some sort. Even monofilament has some weight, so in all but the most forgiving of circumstances, this is a likely a no-go. But I can see a 3' orange balloon with a few hundred feet of mono as a decent signal.

For those interested, I'm working on a lofted 802.11g (or MAX when it comes) wireless solution where I strip off all components of a router except an antenna and power it using super-thin leads from the ground. Think Power Over Ethernet, but with 2 wires and thin resin shielding. Why not just float an antenna instead of a router+antenna? Well, I'll leave that to the HAM crowd here, but let's just say that long copper cables aren't necessarily conducive to antenna function and signal loss.

Anyway, even then, under pristine conditions with tiny load and lifting structure and mild wind (enough to lift without shredding) and you just MIGHT get enough to carry up a few extra oz. of equipment on top of the cable to power it.

The wind resistance you pick up from a balloon will far outclass the reduction in weight if you are dragging it along. Plus, who's carrying Helium into the woods besides scientists?

And if you are talking hot air balloons, well, good luck packing those on a hike.

As an exercise for thinking outside the box, it's fine. For real time survival, well......... (visualize rolling eyes emoticon here).

You would get more use out of some paracord, ziplock bags and colored surveyors tape.

And latex rots in sunlight like Jello on hot pavement.

And that some Airline Pilots had actually spotted him! When he wanted to come back down, -he just popped balloons as needed, -in order to do so.

Of course Airliners typically fly above even Everest's height! As such he'd almost certainly need some Pressurization and Oxygen, -plus Warmth! Perhaps he had something of those, -I don't know.

Re: Survival Balloon? - 02/20/06 09:11 PM

Your sarcasm aside, I just read a week ago about some testing with carbon ribbon for a space elevator and it seems that with 3 8' baloons they held aloft a mile of carbon and fiberglass ribbon about 6 pages of paer thick (probably close to half a mm) and that stuff isn't weight free. So, I have no problem being wrong - in fact, I welcome it in this particular case!

So, I'm sure I'd have no problem standing corrected - I just don't know if the Helium tank weight to signal proportion is a good one for backwoods carry. Maybe on a plane or liferaft it would be more reasonable?

Here's the link:

And I do actually hope to contribute to the discussion - I find it interesting in and of itself and I don't mean to be ignorant or to slam other opinions. And I'm often the first to admit being wrong. :-) Sorry if I came off badly - that wasn't my intent.

Cheers.

Re: Survival Balloon? - 02/20/06 10:08 PM

Oh, wow... well, that's just too funny. I got the opposite from your post. Anyway, I'd REALLY like to know what they used for their balloons. You have to use something that can stretch a fair deal without leaking if you plan on going up very high, but for like 300' or something, thin and light mylar should do the trick. It's finding a 3' balloon in mylar that I've found to be troublesome.

Not to mention that Helium isn't cheap. Those military systems look interesting, but, like I said, the tanks aren't light. I'd *LOVE* to get a system aloft about 300-400' with enough lift to carry up a couple of pounds. I suppose if 45 4' Weather baloons could carry up a person in a lawn chair, maybe 3 of those is more than enough for a little stripped down 802.11g router with thin power leads to the ground!

Man... I had all but given up on that dream and it seems now this discussion has me thinking about the possibilities again. :-)

Re: Up with the Airliners! - 02/21/06 05:30 AM

No worries, and yes, I'm definitely taking a second look at it. The military equipment could prove useful in some circumstances and I think maybe I got ahead of myself going for the big (and heavier) weather baloons when some large and light mylar could perhaps do the trick. If 45 4' baloons can lift a 150-180 lbs, that's way more than projected by the research I was doing where a 3' weather baloon has about 2-4oz. lift! That other means probably at least 3lb for one of those baloons.

Re: Survival Balloon? - 02/22/06 04:23 AM

Just keep safety in mind. A balloon could be used as a high signal panel if tethered to the ground. Just remember that if it's raining, wet string will conduct electricity, i.e. lightning. If you are using a wire tether as a radio antenna, be aware that clear air lightning strikes have been known to happen. Rather than toting a tank of compressed helium, I was thinking of producing hydrogen by a chemical method. I haven't got the details worked out yet, but I'm thinking that a metal & a powdered acid could work (you add a little water to activate). Any chemists in the forum?
Posted by: massacre

Re: Survival Balloon? - 02/22/06 06:18 AM

There are several ways to produce hydrogen without too much hassle. Perhaps the simplest and easiest to acquire is putting electrodes into saline solution. A battery and salt water. Doesn't get much simpler. Actually plain water will do or you'll get chlorine on the O2 electrode if using salt.

Iron and low concentration sulfuric acid will do the trick as well. You can use calcium hydride and water, but that's not as easy to get nor as safe as either of the 2 above, I'd say.

Collecting the pure gas and putting it in a baloon in a field expedient manner may prove troublesome, however. <img src="/images/graemlins/smile.gif" alt="" />

I remember one very stressful final when I saw my chem prof running a battery through water. The electrodes were directly under an bottled filled with water and wraped with electrical tape. The gases displaced the water in the bottle forming a very pure ratio of 2 parts H and 1 part O. Funny, but when you hold said mixture in front of a bunson burner it causes the most unforgetable bang when the gasses reform into water. It's like a canon going off in a confined space. I'm just happy I had the test finished and saw it coming. Everyone else about soiled themselves on the spot.

That reminds me, I think there's a water filtration device that basically creates it's own chlorine in the manner described. Using a primer of some highly saline solution - capfull of water and a salt pill - and a quick zap of electricity, you get a whole lot of chlorine - useful for purifying water.

Concerning the links you have given, -I especially recommend the second one. I believe that it best conveys the Accurate picture by far! And does the best job of Myths Dispelling. Such Myths and Inaccuracies are prevalent enuff in your first link. Even so, I think that it too, is often pretty good.

Within that second link, -Especially as well refer to the "External Links" section at the bottom of the page. Here I especially recommend the following two, -"The Official Site of 'the Lawn Chair Pilot' ", -and "Snopes.com 'Up Up and Away' ".

For all of these specific URLs in themself, -go to these sources. (Small Errors could exist in my description here).

Again, -I feel that these are Far Better concerning the Accuracy of this topic, -than your first link, -Good though it also is!

Re: Survival Balloon? - 02/27/06 09:08 PM

Did someone call a chemist?

The Germans filled there airships with hydrogen (they very limited amounts of helium) by reacting iron with HCl (hydrochloric acid) and/or sulfuric acid. To calculate the amount of hydrogen you'll produce you need to know the concentration of the acid in "moles". For every one mole of HCl you'll get 1/2 mole of hydrogen gas. For each mole of sulfuric acid you'll get one mole of hydrogen gas.

The next step is calculating the number of moles of hydrogen gas needed to fill a volume. The equation there is V=nRT / P where
V = volume in liters
T = temperature in Kelvin (75 F = 297 K)
P = pressure in atmospheres (atm)
n = moles of hydrogen gas (mole)
R = Universal gas constant = 0.08206 L*atm/mole*K)

So, on a nice day let's say you want to fill a 55-gal drum with hydrogen. 55 gallons is equal to 208 liters, the temperature outside is a pleasent 75 F and there are no hurricanes in the forcast so the barometric pressure equals 1 atmosphere. This makes your equation:
n = PV / RT

n = [1 atm*208 L] / [(0.08206 L*atm/mole*K)* 297K]

n = 8.5 moles hydrogen gas

Calculating the amount of acid required to produce this many moles of hydrogen gas is being left to the reader, however you can PM me if you want detailed calculations.

Um, it goes without saying that you shouldn't be smoking while attempting this.

Re: Survival Balloon? - 02/27/06 10:14 PM

To continue the chemistry lesson:

A mole is an expression of a specific number of particles. Since Atoms are so tiny, to humans doing any sort of significant calculation, we need something a bit more tangible. 1 Mole is defined as 6.023 X 10^23 particles (this can be atoms or molecules which are combinates of atoms). It is also equal to the formula mass of a substance expressed in grams. For example:

1 mole of H2O = 6.023 X 1023 molecules of H2O = 18 grams H2O

So, for chemistry, you want to know both the physical weight and the numeric count of those atoms. You want to be able to count out the atoms by tare weight since you cant really pick them out individually except in high-end research.

It's not much different from saying, I know that there are a dozen eggs in a standard carton, and based on that number can calculate what those dozen eggs weigh if I know how much an egg weighs. A mole would be the count and in our case, the weight of an atom is MUCH more predictable than the weight of any given egg, so we can calculate it's weight to a high degree of certainty.

H2SO4 is the formula you want for sulfuric acid

The mass of H2SO4 can be calculated by the atomic weight of its constituent atoms.
2 x 1.00794 (Hydrogen)
1 x 32.065 (Sulfur)
4 x 15.9994 (Oxygen)

Thus 98grams. It just so happens that those thoughtful people who brought you the periodic table of the elements also brought you the weight in grams of 1 mole of each atom. That's what that strange number with all the decimal places is.

So, 1mole H2SO4 = ~98.1g H2SO4

Neat huh?

Blast already told you that you need 8.5 moles of H2 to fill a 55gal drum (volume by liters) and that H2SO4 gives off 1 mole of hydrogen gas.

So 8.5 moles of H2 are produced by reacting 8.5 moles of sulfuric acid with iron under nominal conditions.

You have the weight of H2So4, so you multiply it by the number of moles needed.

You get 833g or .833kg

Not bad for a pound and a half of acid.

Haven't touched on the iron side of the equation yet, but the SO4 reacts on a 1:1 basis with Fe. So you'll need the same number of moles of pure (non-oxidized) iron.

Oh, and H2SO4 has a relative density of 1.8 compared to water (1.0). This oily looking acid (oil of vitriol is it's ancient name) has a density of 1.83kg/L at a 17.6molar (near 100%) concentration. I don't recommend carrying a half liter of full concentration Sulfuric Acid under any circumstances. But I can think of a ready source of H2SO4 when traveling. Make sure to bring some steel wool and use it with a different kind of battery (9V for starting a fire and 12V for the balloon) *wink*

So, how much iron will you need to fill that drum?

Lots of ideas for emergency signaling balloons - 11/23/14 08:26 AM

I did some research, and there has been a lot of thought put into emergency signaling balloons - there are nearly 100 US patents on various facets of the idea (mainly expired), with the first one in 1906!

Here's what I found. If you organized all this material, you'd easily have enough for a book! And I'm sure I didn't get everything - the foreign patent coverage, in particular, is pretty "hit or miss".

Re: Survival Balloon? - Jungle Marker Helikite - 11/24/14 12:19 AM

Here's another survival balloon / distress balloon / rescue balloon / emergency signaling balloon from Britain that has been around for decades.

Allsopp Helikites cites using their "Jungle Marker Helikite" in
1993
, and getting approval from the British Army Jungle Warfare Trails Unit in Brunei in 2002.

The price point ( over 98 British pounds) and weight (2 kg) are more than the $45 US Rescue Me Balloon target price, and there is no integral light (though suspending one is suggested).

On the plus side, it seems available now, looks larger than the Rescue Me Balloon (see photos on the Jungle Marker Helikite page), and is designed to handle (and even benefit from) winds up to 25 mph.

The Jungle Marker Helikite Product Page has lots of photos, including the 2002 Brunei trials.

There's a photo of two Jungle Marker Helikites aloft in Brunei in 2005 at the bottom of this page: http://www.allsopp.co.uk/index.php?mod=page&id_pag=56

That page says: "A special high specification version of the Lightweight Helikite is in a tough, waterproof, bouyant 2kg package with its own helium supply called the "Jungle Marker Helikite". The balloon has a flourescent [sic] orange upper surface for high daylight visibility and can carry a strobe light or light-stick for night use."

The specs for the generic Lightweight Helikite are here: Helikites product spec page: 0.15 cu meters of He, 0.001" thick envelope, 60 grams lift in no wind, 106 grams lift in 15 mph wind, 25 mph wind max, 1300 ft max altitude unloaded, 3 ft x 2 ft, cost: 98 pounds Sterling + tax (may be more for the customized Jungle Marker Helikite).

The Helikites main page says: "Special Forces troops can take a Jungle Marker Helikite from their back pocket, inflate it with 0.4m3 of helium in seconds and then fly it hundreds of feet above the jungle canopy for emergency position location."

Helikites seem to be mainly used for (a lot of) other aerostat purposes, and have been around for a long time - the basic US patent: US patent on Helikite was filed in the US in 1994 (20 years ago) and cites a priority date of 1993 (likely the UK filing date). Due to transitional US patent rules, I suspect that the US helikite patent is good through 2017, but IANAL - if it matters to you, get legal advice.

The Allsopp Helikite Wikipedia entry dates back to 2006!

Wouldn't a kite be cheaper/ lighter?

You'd think so. I'll take a crack it this, keeping in mind that I can't personally recall the last time I flew a kite.

The only (but seemingly excellent) commercial visual distress signal kite I found on the market, the Sky-Alert Parafoil Rescue Kite, retails for $53 US, and seems targeted at the marine market.

It requires 5 knots (6 mph) of wind to get aloft, and 8 knots (9 mph) wind to loft a strobe. It is a 28"x38" parafoil with 12 feet of streamers, likely based on this patent.

I'm pretty sure I could buy a cheaper kite - so why has this one has survived on the market since at least 2002 , likely since 1986?

A few points in its favor that I can see:
  • It is USCG certified as meeting the USCG requirement to carry a distress flag, which its target customers require anyway, and seem to go for about $10, so there's sort of a $10 discount here.
  • As a parafoil (non-rigid frame), no assembly required, it likely packs compactly, and is tough
  • It apparently has the lift to hoist an honest-to-god USCG compliant strobe (which is the light I'd want up there)
  • It is marked with the standard USCG distress markings, so there is some hope that the message will get across.
  • The target market (especially sailboat owners) are likely to be out in windy enough conditions to loft a kite.
  • Will fly when wet.

{ Late update: Non-emergency Kayak Kites in this class go for $45-$49 with no USCG certification and no emergency markings, so I think the Sky-Alert Parafoil Rescue Kite is a bargain price when you consider the effective $10 USCG credit and the fact you get emergency markings included. On top of that, soft kites of this class seem to be recommended as the easiest to fly and easiest to setup/takedown (essentially, none required), so it seems like a good fit.}

The choice of balloon vs. kite depends on the wind speed. No wind, no kite. In the local foothills I tend to hike in, there's rarely enough wind for a kite. On the other hand, as the wind picks up, balloons look like a poorer and poorer choice. The British Jungle Marker Helikite, as a hybrid balloon/kite, spans a 0-25 mph wind range, having the advantage of living in both worlds.

The Balloon and Kite Antennas site looks to be a fount of information about using balloons and kites to loft equipment from an expert facile with both ( he apparently habitually leaves his kite/balloon lofted antenna 50 metres in the air unattended overnight). Here's is a guide to what he recommends as a function of wind and weather, which transitions from balloons through hybrids to pure kites as wind speed heads up to 45 mph: Recommended lifting units vs. wind speed

One proven approach is to have both balloon and kite handy, and switch off as wind condition change. For hoisting the antenna of the German/British/American emergency dinghy radios of WWII, the kit was equipped with a box kite for winds above 13 mph, and two 36" diameter balloons and two hydrogen generators, for when the wind was under that. See this great page: Gibson Girl Part I: Air-Sea Rescue

I did find this: 1869 patent mentioning lofting a light with a kite as a distress signal

Re: Lots of ideas for emergency signaling balloons - 11/24/14 03:05 PM

Is there any information as to the effective sighting distance for any of these items?
Posted by: CANOEDOGS

Re: Lots of ideas for emergency signaling balloons - 11/24/14 06:50 PM

the outdoor magazines ran ads some years ago for signaling balloons.the ad had a drawing of a lost hunter sending one up but if a recall it just came with 50 feet of line.
the ads went away after awhile as it was just a bad idea.
wind would push the balloon down into the trees,you needed lots of line and how big would it have to be to be seen?
modern times now and PLB's are cheap for what they offer in the way of rescue.

Re: Survival Balloon? - 12/06/14 10:27 AM

Found this in my shopping list for if i ever get to the USA. Can' remember who posted it or when:

VARIABLE LENGTH PLASTIC BAGS
I was killing time in a West Marine the other day when i came across a nice survival addition, the Knot-a-Bag plastic bag refills from Davis, the weather station and sextant company. It's about $7 for 3 rolls.
Basically, it's exactly like the vegetable bags you get in the supermarket except stronger and each roll is only 1 1/2 by 3 inches and weighs less than 2 ounces. It is 10 meters of 8" diameter polyethylene bag material. You pull the plastic out of the center and cut it off and put a knot in the end to make a bag.
What can you use it for?
It's food suitable, so you can carry lots of water, berries etc and could use it as a transpiration bag over a leafy branch to get water.
It's very strong, almost as good as rope for tying things. Or you could use twisted strips of it as lashings for your shelter, or holding a dressing on etc.
If you spread it out, you can make a triangular bandage out of it to hold an arm.
A longish piece can be stuffed with non-pointy items and used as a billy bag over your shoulder.
It's flammable, will light from a flame but i can't start it with a ferro rod...
Since it's airtight, you could inflate one to use as a buoy to hold yourself up in water.
You can make a hat, or a brooch or a pterodactyl...
The only thing it's not really good for is shelter itself or weather protection, a trashbag would be a better choice. But you could still put lengths over your arms and legs and wrap some of it around yourself to keep wind and rain out. So it's useful and small enough to stow in my kit bags.
