Alex And Flat Stanley At Pyramid Lake


Song:  Drops Of Jupiter

Group:  Train

This song is light hearted and up beat...
just as this day trip was.



We stopped by a neighborhood Thai restaurant on our way
to Pyramid Lake...
a terminal lake 1/2 hr. N by NE of Reno.


It is fed almost exclusively by the snow melt of the Sierra Nevadas
which feed Lake Tahoe.
Lake Tahoe feeds the Truckee River...
which then flows through Reno...
and ends in Pyramid Lake.


Flat Stanley is a popular School Project
where school children make contact with people 
from around the world and ask that they take him along
when they travel in their area and take pictures with him in it
(they send a copy of Stanley to you).
You would then E-mail the pictures and send Stanley back.
The children then get to see areas of interest
(along with a brief description of the location)
in other parts of the world...from a local's point of view.

My wife had a Blog friend who had been asking for a temporary home
for Stanley for a School Project.  She agreed, and we received Stanley
just a couple of days ago...and so, here is Stanley on his first excursion...
enroute to Pyramid Lake.



Pyramid Lake is part of an Indian Reservation of the Paiute Tribe.
As their laws are a little different...
they have some convenience stores which sell all types of Fireworks year round...
and you may shoot them off at certain spots near the lake.
We will certainly do that in the future.





Alex and Stanley as we arrived at the lake.
Pyramid Lake has a trout hatchery and some of the 
World's best Trout fishing is supposed to be here.
The trout grow to exceptional size here and the record
weight trout caught here was over 40 lbs.  Other sizes
regularly caught here weigh 10 to 20 lbs.

Alex loves Trout...
he wanted me to go fishing to catch some for dinner.

Perhaps sometime in the future we will do some fishing.
It would make a good outing.



At the Pyramid Lake Museum

Throughout our drive to different parts of the lake...
I had questioned Alex on the surroundings...
more to teach him critical thinking than to teach him about the lake.

I always try to have him observe and to analyze what he sees...
by seeing what is there and asking himself why...
and why not other things....about patterns and disruptions of them...
to tell him much about the true nature of his surroundings.


I always try to revisit concepts previously taught.
I am going over the use of shadow stakes with Alex...
 to determine direction using the track of the sun.








Some Paiute handcrafts.



We had a nice day.
Alex enjoyed himself...
we got some educational milage out of this trip...
Stanley got to see some new sights also  :)

We will be taking Alex and Stanley to the University of Nevada Reno
Planetarium for our next outing.

Basic Survival: Fire - Implements And Field Expedient Methods Of Fire Starting



Song:  Time / Breathe Reprise

Group:  Pink Floyd

I had chosen this particular track of Pink Floyd's
Dark Side Of The Moon Album because from the beginning to the end...
the music (not necessarily the words) describe what it is to feel 
the ominous presence of an imminent life altering event...
the gut gnawing...stomach churning knowledge that something 
is about to go horribly wrong
(the ticking of the clocks)...
 and then the horror as you see the event unfold before you 
(the alarms going off).

The floating, almost surreal effects of the music that immediately follows...
closely mimics the feeling as you start adjusting to your new situation.

As the vocals start...
you are assessing the situation...
getting to know your surroundings...
taking stock of what you have and what you will need...
and need to do.

The guitar solo signifies the coalescence of a solid plan of action...
the steady encouragement and confidence that only comes with
 having preplanned materials at hand...
and the knowledge of how to use them to resolve the situation.

The re-initiation of the vocals afterward...
 describe the implementation of your plan of action...
your steady forward motion toward civilization...
and the successful resolution of your survival situation.

The blending of the next song (Breathe Reprise)...
is of you back at home...
cozy and warm and thinking back at your averted disaster...
which could then be thought of as an adventure...
because of...
knowledge and applied forethought.


Dramatic you say?

I assure you...
any situation where great injury or death could be the result
should you not act or react appropriately... is quite dramatic.

Just think of this musical track as your survival symphony.


Shiroi, are you saying that the key to survival 
lies in the music of Pink Floyd?

No...
I am saying that the key to the universe 
lies in the music of Pink Floyd  :)

Sorry...
Pink Floyd is my all time favorite group  :)
(they have been for almost 40 years)


No, while music is a great tie in to your emotions...
and emotions can alter your behavior...
both, positively and negatively...
the key to survival lies in your...
 pre-planning...
accurate assessment of your situation...
and the rational responses in your ability to adapt, to improvise...
and to formulate, and carry through, a correct plan of action.



In case you have you not already read the initial article explaining important concepts...
read the following article first:



This, of course, leads me into the next segment of Basic Survival.

Fire - Implements And Field Expedient Methods Of Fire Starting


The nature of this article shall be the description of commonly used 
implements of fire starting for the Bug Out Bag...
and some field expedient methods of achieving the result of fire...
using items, either not originally designed for fire starting...
or from items in the environment.

I will be explaining some methods of constructing a safe way
to efficiently burn fuel and concentrate heat, reflect otherwise wasted heat...
 and a way to transport heat from its source to slow release it...
using elements from the environment...
all for either cooking or heating an improvised structure...
in later articles.


I must stress this once again...
it is precisely because improvised methods are far more
difficult to produce the effects that can be gotten from 
dedicated items that had been stored for that purpose in the first place...
that a properly outfitted Bug Out Bag is so important.



With this in mind...
some common camping fire ignition sources to consider
for your bug out bag...
and some items that have other uses that should also be packed
for their use as a back up.

As with the water purification methods...
have multiple sources in case of loss or failure of
any one source.

A key to survival is redundancy in equipment and planning.


Ok...
the obvious first pick for an ignition source in many peoples minds...
and then I will tell you some reasons to not have it as anything but
a convenience for non-extreme environments or basic camping.

Do not rely on butane lighters as your primary source of fire starting.

Some major problems - 

1)  Butane does not volatilize well (change from liquid to a gas) below freezing.
They now have Butane mixtures...however, they don't operate well
in freezing temperatures and run out when the other gas providing the pressure
runs low - with half of the butane left in the container.

Now, that is the temperature of the fuel itself.
It may get below freezing and so long as the lighter is kept above freezing...
or the lighter could be pre-warmed before lighting, then....

2)  Butane doesn't ignite well at altitude.  Altitude alters the 
fuel air mixture ratio needed to sustain combustion... unless there
is an air fuel mixture ratio adjuster on the lighter (some have them).
Butane lighters also tend to leak out...especially with an increase of altitude.

These reasons also apply to not having a Butane camp stove...
besides having to stock up on the containers.



3)  Most butane lighters are shoddily constructed.  
The housing is relatively easy to crush or shatter.
The tops are easy to knock loose.
The gas valve can easily be activated accidentally.
They often leak out over time - not a choice to have in a bag for long storage.
Cannot be refilled with alternate fuels in the field.



A Zippo type (non-butane) refillable lighter would be ok if...
you don't fill it until you need it in the field.
You can keep the fuel in a dedicated fuel bottle
(although I cannot vouch for the long term storage capability of the fuel).
It is field serviceable and alternate fuels may be used as one can find them.
It is simply a liquid fuel and wick system.


There are some lighters that use the resistance of a metal wire
and the power of a battery to supply the current.

Not the best of choices since the battery is the obvious weak point
in the system.  You want something that will not degrade with time
spent in the bag.  The contents of the Bug Out Bag should be thought 
as something in which each piece is so reliable that you could store it
and hand it down from generation to generation and 100 years from now...
everything would still work.


Well...
how about some things that will light easily and will last nearly forever.

Ok...
but before you even think about starting a fire...
you must know how to safely sustain one.

It does you no good to have a fire that dies because you hadn't pre-stocked
your fuel pile...or worse...one that you had depended on to keep you warm
in the middle of the night...and sputters out when it is too dark to effectively
find more firewood.

Gather more than you will need for the night at the fire site before hand.
You will need to stock up on larger logs or branches if you can...
many smaller branches and twigs which will ignite the larger pieces of fuel...
a lot of smaller twigs, leaves, dried grasses...etc to ignite the larger twigs and branches...
your tinder source...finely shaven wood, dried moss...etc...to ignite the smaller fuel.

You will then want to pre-stack everything.

I will discuss the gathering and stacking of the firewood for efficient burning
for special tasks in more detail in another article soon.

You must also consider placement of your soon to be fire.
You don't want to be directly under a tree...
especially in snowy conditions...
for obvious reasons...
heat rises...
melts snow...
whole globs of snow will either drip in the fire...
or will come down in a whole mass...
poof...no fire.

Another reason to not light a fire underneath a tree...
again...heat rises.

Should the fire be of any appreciable size...
it could catch the tree on fire...
especially if it is one that has oils in the needles
(think christmas tree)
or has the dry leaves of Autumn.

Now you may be thinking that it would make a great signal fire to rescuers...
that they would find you
(only to be used in extremely dire emergencies and then only with a lone tree 
away from other flammables)...
the problem then arises if the tree fire becomes a forest fire.

They will find you alright...
more than likely...
extra crispy  :)

Ok...
Plentiful amounts of fuel...check.
In the right location...check.
Firewood is stacked and ready to go...check.

Then, and only then, should you even consider lighting a fire.

Now...
 an easily ignitable, relatively long burning (3-4 minutes) and utterly reliable
initial fire starter...one in which you may ignite the tinder with... is not
only very inexpensive, effective, can be stored a very long time without degradation 
and is easily gotten and made...
vaseline (petroleum jelly) impregnated cotton balls
(in a tightly sealed container - under warm conditions it liquifies).

An example of the petro-cotton balls in action:


It is readily ignited with a ferrocerium and steel fire starter.

Both are water proof and reliable...
and very inexpensive.

You don't need the petroleum fire starter...
it just makes it easier.

The ferrocerium rod and steel fire starter throws off incredibly hot sparks...
however it won't ignite larger pieces of wood.

You will have to have...or make your own tinder from the environment.
Obviously dry material...you could make light wood shavings from larger pieces.

Now, as good as the ferro rod is...
another great piece of equipment uses the ferro rod in conjunction
with a magnesium block.

The shavings from the magnesium block would burn very hot for a good 
3-4 seconds (depending on the size of the shavings pile).

The advantage to this is when your tinder is wet and the ferro sparker alone
won't ignite it.  You still need the tinder with the magnesium shavings...
it is just easier to get the wooden tinder started under wet conditions
(however, the petroleum cotton balls would be better)

The ferro rods and ferro/magnesium combos are so inexpensive ($3.00 on up)...
last for thousands of strikes each...
extremely reliable in dry tinder ignition...
or even wet petroleum cotton balls...
it only makes sense to have multiples for each person.


A general rule of thumb...
when you have the capability to use a resource other than your own...
and your situation is uncertain...
save yours for later in case of need.

Take the time to gather or make your own tinder...
use the petro balls for when dry tinder is not to be found.

Just as a basic principle...
tinder burns easily because of its increased surface area.
This allows the material to heat up quickly to its ignition point.

You can make your tinder from a wet tree...
you just have to shave the wood into extremely fine shavings...
a 3-4 minute petro ball flame would have the effect of quickly 
drying and heating the wood shavings to ignition.

This same principle applies to starting a fire with wet wood.

You merely have to start small (lots of surface area)...
lots of the material to dry and ignite the next step up in the wood pile...
and eventually you could burn wet logs.

To do this would take a tree-mendous :) amount of effort...
it would involve a lot of gathering and preparation...
but it can be done.

Me...
were I in wet conditions...
unless I absolutely needed the fire to purify water...
or to cook questionable food...
I would lie comfortably in my sleeping bag...
and think about how I wouldn't have to worry about getting water...
to hell with the fire  :)

Actually, not so much of a joke...
were you to use it to cook a relatively small amount of food...
and the energy expended trying to light a fire in wet conditions
were more than that to be gained by the food...
you shouldn't do it.


Another unusual piece of equipment...
one that operates on the principle of air compression
(this effect ignites the fuel in a diesel engine)...
is the Fire Piston.

It is a simple cylinder with a close fitting rod which holds a piece of 
cloth or other easily combustable material
(dry moss, grass, fine tinder...etc)
in its tip (the tip that gets plunged into the cylinder)...
and a push handle at the other end.

You would rapidly plunge the rod down and back...
in that split second...
the air heats up enough to leave the combustable material aglow.

You would then transfer that glowing ember to your pre-set tinder
and gently blow on it until you have a flame.

I have one of these...
however it is more to demonstrate the effect to my son, Alex...
than as a dependable piece of equipment.

Its weakness lies in the rubber o-ring at the tip.

Rubber degrades over time...
and while a field expedient repair could be made with cordage
or other material that could seal the air from leakage under compression...
it is far easier to start a fire by a ferro rod.

Now the good thing about the Fire Piston
lies in the lesson to be learned in the underlying principle...
and in its construction.

Were you to be in the wilderness long term...
and you only had the environment to construct a fire making implement...
a Fire Piston could be constructed from wood, bone, horn...etc...
with an o-ring constructed from hide or cordage.

Although it would take a lot of front loaded effort to fashion one correctly...
it could be used almost effortlessly and quickly from that point forward.

Rather than to have to use friction...
wood on wood...
by the various methods...
each of which takes much longer and much more effort...
each and every time you would need to make a fire...
the accumulated time and effort saved...
 justifies constructing a Fire Piston.


An example of what I have been talking about:



At the end...this guy actually was clumsy in his attempt to turn the ember
into a flame.  You would have the ember in a much larger handful of tinder...
commonly referred to as a bird's nest (it looks like one).

With the appropriate tinder...
it should go to full flame in a few seconds of blowing.


Now as for making a fire piston or fire starting by friction...
I suggest looking it up in detail on YouTube.

Know the principles involved and the general construction of them.
It is a good thing to keep in the back of your head in case 
the next Zombie Apocalypse completely collapses society...
forcing you into exile in the deep forests...
and no other means of fire starting exists  :)

It takes practice, effort, patience...
and while fun...
beyond the scope of this article.

It is a good thing for a parent to teach their children...
just for the applied science behind it.


Now...
other fire starting implements that your Bug Out Bag should have...
sunlight refractors and reflectors.

Your only limiter would be the absence of sunlight.

A typical light refractor (redirects light going through it)...
 a magnifying glass or a credit card size fresnel lens.



A good pocket size one of either can be had for a few dollars.
You may also use your Binoculars as a source of the magnifying lens.
Eyeglasses can also be used...although it depends on the amount and type of correction
as to how effective they would be.

A typical light reflector (redirects light as it bounces off it)...
a solar cooker or even a solar cigarette lighter
(a parabolic reflector).



They actually sell this solar cigarette lighter for under $10.00.

It is the principle behind the concentration of light to make a fire that makes
this a lesson that is so valuable.

Should you be without a solar means of fire starting...
you could improvise a refractor lens in freezing conditions by 
shaping CLEAR ice into a lens...
or under normal conditions...
a clear sandwich bag of clear water can be made into a lens...
in the absence of other means and being in dire straits
(I know... Zombie Apocalypse again).

Making a reflecting solar concentrator is far easier...
any highly reflective surface that can be manipulated into a parabolic shape would do.


Another means of fire starting with what you may have in your Bug Out Bag...
or more likely than not...what you would have on you naturally...
such as battery operated equipment.

A hand crank generator would be a good non-degenerating piece of equipment to have
(for running or recharging your electronic equipment such as...
cell phones, flashlights, radio...etc)...
a portable solar panel recharging unit is also good to have...
but generally doesn't have the power to heat an element.


By spanning the poles of the power source with a fine wire..
the wire gets red hot almost immediately.


Now...
for a field expedient method of generating electricity (static electricity)
to heat a fine wire with only dried pine needles and rubber soled shoes.

First you would spread a thin mat of dried pine needles on dry ground...
while holding each end of the wire in opposite hands...
you would then step on this mat of dried pine needles with rubber soled shoes...
and start rubbing the shoes back and forth REALLY FAST and...

I am, of course, joking  :)

Sorry...
I couldn't resist...
it is getting very late...
I am tired and off to bed.

Our First Real Snow In Reno


Song:  Zeynep's Romance

Artists:  Omar Faruk Tekbilek and Brian Keane




Alex's first at home snow fall.  
It was also only the second time in his life that he has
really experienced snow.









Alex studying with a full view of the snowfall.


Mr. Rabbit is our shy, but frequent visitor in the backyard.

We really love the change of seasons that we get to experience here.

As a family...we lived in the central valley of California...
where there really isn't a dramatic shift of seasons.

Although the snow here never reaches the depth of many parts of the world...
we still get to enjoy the benefits of snowfall here...
without the need to shovel our way to the street.

Although this snowfall was relatively light...
and more than a month overdue...
and at times the snow depth does necessitate more
extreme measures to move about outside...
it is only during the rare really heavy snowstorms that it happens.

The snow here is usually of minimum depth...
just enough to enjoy...
without backbreaking snow shoveling for more than a couple of weeks a year 
(or so I have been told by locals).

There is supposed to be a break in the weather in a couple of days.
We will probably head to Lake Tahoe when the weather lightens in the Sierra Nevadas.

Basic Survival: Water Storage And Transportation Containers




Song:  The Story Of Suleyman

Artist:  Omar Faruk Tekbilek


In case you have you not already read the initial article explaining important concepts...
read the following article first:


Problem...

Water weighs approximately 8.3 lbs. per Gallon (1 Kilogram per Liter).
We can't last long without it.
In many survival situations, a source may not be reliable.
You need to plan on using 1 Gallon a day to keep hydrated
in a hostile environment and under extreme exertion
(for planning purposes...circumstances may force using far less).


Unless you have a reliable source of water the whole way
to safety (rare)...you will need to transport it from source to source.


Major points to consider when buying a survival water container
(you don't necessarily have to think canteen)...


1)  It must NOT be porous.

While this would strike many as immediately obvious...
consider some water bags constructed for desert use.
They are built specifically to slowly leak water continuously
through its skin to allow evaporation to cool its contents.

This, of course, would be bad for two immediate reasons.

One...
for obvious reasons...
water may very well be a rare find.
You would need every last drop of it...
cool or not.

Two...
a water bag that is porous will keep pathogens in its pores...
making sterilization of the container almost impossible...
as well as infecting everything the leaked water, and the container, touched.





2)  It must be able to hold relatively large amounts and be rugged.

This automatically excludes the hard translucent sports bottles.
Many are made with a plastic that could break instead of bend with a force.

This includes using any canteens with any easily breakable parts
(the cap is particularly vulnerable in some).

Your water containers could very well be your life line in a dire situation.

While true military ones are very good...
fake equipment is sometimes listed as G.I. Type or some other misleading saying.

You must get Official Govt. ones...
not the cheap fakes.

They are often not only some of the best ones around...
they can be had for very reasonable prices.




3)  Divide up the number of water containers into many smaller ones
(keep no more than 1/4 of your supply, per person, in any one container...
as protection against loss, leakage, fouling, damage...etc).

  Each person must carry their own water.

Remember...a 5 gallon jerry can of water would not only place an extreme 
burden on the poor man carrying it (over 40 lbs)...
it would be placing your survival at risk should the container, or the person...
be compromised in any way.


Another important point...
extreme circumstances bring out extreme emotions and thoughts.

Imagine when water gets short and one man holds most of the supply...
 a potentially very bad situation that could be played out in any direction.



4) Spare no expense

This is one of two areas in which you must not compromise in...
the Purification / Storage of water...
the Sleeping Bag.

If you must compromise the quality of your equipment due to expense
or weight...do it else where.

The lack of either area could mean a relatively quick death.


5)  Never use a container that had unsterilized water in it
as a container for sterilized water later on
(unless sterilized in the field...
extremely difficult to do without chemicals or high heat.
Another reason to always carry Chlorine or Iodine tablets).


Just one of many examples of canteens that are not only
rugged and reliable...but are very reasonably priced.



This is an official U.S. Govt. Issue 2 qt. canteen
(true soldier issue canteens have a covered indent nozzle in the cap...
permitting usage of a gas mask hose linkage so soldiers may
drink from their canteens while remaining in their gas masks).

They are regularly sold on line for $6.00 - $7.00.



An official U.S. Govt. issue 2 qt. canteen cover
(desert scheme)
notice the little pocket in the front...
for sterilization tablets.

The inside of these bags contain fleece for insulation.

They also have equipment clips on the back.

They go for $5.00 to $6.00 on line.

4 of these per person would provide 2 Gallons
and would permit the 1/4 ratio per person container 
division necessary to ensure against container loss, malfunction or mishap.



For under $50.00 per person...
you would have the makings of a good water transport system...
with the back up sterilization attached to each canteen.

Ruggedness, reliability and redundancy...
a very good start.

However, by no means stop here.

This would be a minimum.

Think about a collapsable larger container (for each) in case of extreme
travel between water sources.

You may also consider having one each of a stainless steel 2 qt. canteen
for an emergency heat sterilization vessel
(dual purpose / redundant boiler).

Basic Survival: Basic Field Expedient Water Purification Methods


Song:  In The Morning Light

Artist:  Yanni


In case you have you not already read the initial article explaining important concepts...
read the following article first:


I have two basic objectives in this article:
(as my focus is on equipment for the Bug Out Bag...
I'll save the methods of water location for later articles)

1)  To have you pre-plan in the stocking of at least two viable water
filtration / purification pieces of equipment for your Bug Out Bag.

2)  To give you the basics of water filtration / purification 
through a field expedient improvised method as a backup
for equipment failure or loss.

Having a source of clean water is absolutely vital.

Under extreme exertion and climate conditions...
your need for water, to prevent death by dehydration...
 for a normal healthy person...
 is measured in just a few days.


-----------------

There are two extremely important points I must emphasize:

1) You simply MUST be able to secure potable water...or you SHALL DIE.

2) You simply MUST be able to secure potable water...or you SHALL DIE.

I hope that was clear enough.

-----------------



First...
I will cover some very basic methods of water 
filtration / purification that are frequently used by portable water purifiers.

Note:  You must research on your own as to the use of particular brands...
they vary widely in price.  I purposely did not include a direct link to these products
as I do not wish you to believe my advice to be tainted by financial gain.

You must plan on at least two separate pieces of equipment for water purification
for each person...
it is simply too important not to.

1)  Mechanical Filtration:  Using various mediums of decreasingly
smaller holes, or avenues of passage (permeability)...
to filter out increasingly smaller particles
(including cysts and bacteria).

They usually start with a fine screen of some sort
and advance through increasingly fine materials 
until reaching an ultra fine ceramic filter or a
block of activated charcoal.

Some good examples:


Relatively inexpensive and effective.


Not so expensive...
higher output and can use to store purified water directly into containers of your choice.


Effective and very inexpensive.
Lightweight and small.

Although you cannot really use it to store purified water into containers...
you could merely store and transport unfiltered water and use this on it.
This type of filter is a must have as a backup.


2)  Reverse Osmosis:  Technically, an ultra fine mechanical filter...
it uses a semi permeable membrane for its filtration.  

This unit also uses the grosser forms of mechanical filtration as 
a pre filter.  It would simply clog up too quickly without them.

An example:


Very effective...the best portable out there.
It filters to a much higher degree than the rest.
It is, however, relatively expensive and bulky.

As it uses a semi-permeable membrane and pressure to force the water through...
it is a Reverse Osmosis filter
(contrary to normal Osmosis where lower concentrate solution naturally diffuses
to the higher - the reverse process is used... hence the name, Reverse Osmosis...
the higher to the lower by unnatural means...
 outside pressure as applied by the pneumatic pump of this apparatus).

Note:  While Reverse Osmosis is one method used to desalinate water...
it takes an extraordinary amount of pressure (up to 1200 psi).
This unit simply cannot generate the force necessary to do so.
Although there exists portable units that can desalinate water 
by various means (including Osmosis)...they are either cost prohibitive...
or take too long to produce appreciable amounts...
you could just distill instead. 


If, however, your live in an area that has extensive supplies of brackish 
or other high salinity water sources, including the ocean...
then a portable desalinator is a must.


However...
of all the portables not used to desalinate...
 this has the smallest pore size...
and so, filters out even viruses.

If you can afford it...
this is the gold standard for portable water purification.


3)  Ultra Violet Sterilizers:  To be used only after one of the above methods
 (although not necessary).  

There are simply too many variables that can affect 
the efficacy of such a method...besides being inherently
unreliable in the power source and bulb as a prime method
(Should the water be cloudy...it won't work...
time of exposure...must be enough...etc).


4)  Chemical Purification:  Chlorine, Iodine or other types commonly used
as tablets or liquid drops to add to your water containers.



A good third back up...however, you should use some sort of mechanical
filtration method first (at least straining through a t-shirt).

Very inexpensive, lightweight and small to carry.


-------

Some commonly used field expedient methods to purify water
when no other methods exist (no specialized equipment such as the above).



1)  Boiling - A time tested method of killing various pathogens...
such as bacteria, viruses, protozoans...etc.

There are, of course, drawbacks to such a method as a primary 
means of water purification on the move (base camp fine).

You must have the fuel, container to boil it in, and the time to build the fire...
and to boil enough to store.  You will also lose some in the boiling process.

Know that in order to be safe...
you must bring the water to a ROILING boil for at least 1 minute...
at sea level.

As altitude lowers the boiling point of water from that at sea level
(approximately 2 - 3 degrees for every 1,000 ft in elevation)
and it is the time spent in temperature that kills the pathogens...
then 2-3 minutes should do the trick.

Also know that a relatively large container and a lot of fuel
will be needed to fill an appreciable amount of water to store and carry.

Even without special equipment to boil water...
ones can be made with a minimum of vegetation.


The whole idea is to have a container to hold the water while the water boils.


This can be effected by broad leaf plants...
even by the bark of trees.


You needn't worry about burning away the container,


So long as the heat source is not too concentrated on any one area...
or the material so thick as to not be able to conduct the heat directly to the water...
the water will absorb the heat and boil and keep the material below the point of ignition
(stay away from plastics - most breakdown in heat).


That is precisely why you can boil water in a paper cup while held directly over a flame.




2)  Simple Steam Distillation - This method can be used to effect desalination as well as 
for removing many undesired impurities from water.


However, you must realize that simple steam distillation does NOT
make the water pure.  It only keeps anything that does not 
volatilize at, or below, the point that water does... out.  
Its basic function as a field water purifier is for desalination.


Example: You cannot get water which is heavily contaminated with certain petroleum
compounds and expect drinkable water from it.  The contaminates would evaporate
and re-condense along with the water.

All Simple Steam Distillation is...
is a method of boiling a liquid (this case...water)...
and having it re-condense on to a cooler surface for collection.


As this is a more lengthly and effort inducing process...
it is more appropriately done at a camp.


This takes the most equipment, time, effort, and fuel... 
of the basic methods of water purification.


The only real piece of equipment that is not normally included
in a Bug Out Bag would be the condenser coil or hose.


This is easy to get off of your vehicle were you to be stranded...
you could make your own from the environment...
or you could merely have the steam condense on any cooler 
surface and directed into a container.


Just think tube from a flat pliable surface (roll from items in your bag)...
or from vegetation or bark
(it must be long and cool running enough to convert the steam back into water).


For large amounts of water to fill containers...
any center indented dome large enough to cover the pot
(best done when it is cool)
with a catch container hanging below the indentation 
and from the sides...would do
(easily made from tarps, ponchos...even wide leaves...etc).


You could also easily dig on an incline...
a trench which you could line with flat rocks...
and the trench capped with flat rocks
(if it is long enough...the end may also be capped)...
with the boiling water at the bottom entrance.


The steam would rise in the cave or long tube...
condense on the rocks...
run down to be collected
(with the tube end uncapped...
this could also be used to preserve large amounts of meat...
as a fire at the base without the water pot... is a chimney oven.
Obviously...if you are to do both...purify the water first).


So long as you know the principle of the condensation of steam
onto a cooler surface that could collect the resulting water into a container...
you could then improvise from the environment to desalinate brackish or seawater.




3)  Evaporative Still - This is the same as the Steam Still except that it does
not involve the use of high temperatures.  It commonly involves using the sun.
It is commonly called a solar still and is also used at sea as an emergency device
to desalinate sea water in case of dire emergencies necessitating taking to a life raft.


It is not terribly efficient and the amount of water collected generally does not
justify constructing them.


4)  Ultra Violet Radiation/Solar Heat - 
So long as you have a container that is no deeper than a few inches...
(a plastic soda bottle lying on its side with full exposure to the sun)
and is capped to prevent the evaporation of the water to be purified
(this method will NOT desalinate)...
and is fully exposed to the sun for at least 6 hours...
tests have shown a dramatic reduction in pathogens to levels
which would be far safer than not purifying at all.


Not the preferred method since it is not nearly so safe as is boiling...
besides the wait time and the large number of smaller containers necessary...
unless you could construct something from your surroundings
( large clear plastic bags with 3-4 inches of water depth with the bag
allowed to spread out).


The main pathogenic destroyer is the UV-A rays...
so the principle is for transparency of material...
and limited depth of water.


The solar heat helps kill the pathogens...
it is not the major purifier.


Just something to keep in mind...just in case.


If you don't get anything else from this article...
as you can see...
it would be FAR wiser...
efficient and effective...
to get some good water purifiers before the need arises...
instead of having to improvise in the field
(not always possible).

Never doubt the need for clean water...
or the difficulty of extracting it from your environment
should there be no readily apparent sources available
(and so the need to have containers to transport that which you do find).

I have given you just some of the very basics of field water purification.

That is only one third the equation to prevent dehydration
(unless there is always a supply at hand to purify...rare).

The other two will be covered in later articles
(finding/extracting water from the environment...
and the storage and transportation of it).
