The true value of a Thermos in prepping
Why you should add a thermos to your preps

Do you have a Thermos as part of your preps?
A Thermos might seem like an odd prep, but it really can be a
valuable tool to consider when fuel is in short supply or when
your time is more important. There is true value of a Thermos in
prepping.

Having a Thermos is something not often talked about in
prepping circles, perhaps because younger preppers never brought
a thermos lunch to school. Whatever the case, without experience
in using a Thermos it's easy to overlook the simplicity of this
important idea.  Here's why a thermos can be useful in prepping...

Why use a thermos in prepping?
The obvious reason to have a Thermos is to have a hot meal on
the go. Not only can you save money by bringing a hot lunch to
work or school, or while travelling, but you'll feel better with a
hot meal. The heat in the food will provide you with more energy
and you'll stay warmer in winter than a sandwich. Warm food
provides more energy and is comforting, but there's so much more
to this basic concept.

#1: You can prime a thermos to keep your food
warmer.
If you've ever used a Thermos and wondered why it never seemed
warm enough, then you've not been using it properly. You need to
prime your Thermos! Pre-heat it.

Priming a Thermos, or pre-heating it, is a way to get your
Thermos working to its full capacity. Essentially you warm your
Thermos with hot water to make it work better and last longer.
Here's how...

How to prime a Thermos to make in hotter:
  • Step one: Boil water.
  • Step two: Fill the thermos with the boiling water, seal up
    the thermos, and then wait five or ten minutes.
  • Step three: Empty the water and replace it with the food
    and seal it up.

Now your Thermos (vacuum flask) will keep the food warmer
longer through the process of convection.

Priming a Thermos is especially important for trips you may take,
like hunting or fishing, where you'd like to take a break with a
warm cup of soup, coffee, tea or cocoa, but don't have the time
or ability to make a fire. This can help you save fuel, too.

#2: You can also pre-chill to keep your beverage
cooler!
Priming your Thermos to make it colder is also possible. You can
maximize the incredible insulation technology of a Thermos when
you either pre-chill or pre-heat the beverage bottle just prior to
use. In the same way you fill the beverage bottle with hot water
to keep your food warmer and attaching the lid and letting it rest
for a few minutes, you can do with cold water.

Adding icy cold water to the Thermos before your food and
beverage can make a huge difference.

How to prime a thermos to make in colder
  • Step one: Fill the thermos with ice water, seal up the
    thermos, and then wait five or ten minutes.
  • Step three: Empty the water and replace it with the food
    and seal it up.

Now your thermos will keep your drink cooler, your fruit more
refreshing and your applesauce or pudding more appealing. It's
not going to keep your ice cream hard, but you might get a tasty
milkshake to sip!

#3: Consider that thermos cooking conserves fuel.
A thermos is an efficient way to cook when fuel is valuable as in
a time of crisis. If you cook a meal for breakfast, you can use the
same fire to cook your lunch and keep it hot.

When you need to conserve the fuel you have in crisis, a thermos
because a precious commodity because it allows you to keep the
heat.

#4: Try Thermos cooking as an emergency cooking
method.
You can boil water and then use the retained heat to cook in a
Thermos. This saves you time and fuel. For Themos cooking, it's
important to select a wide mouthed Thermos.  

Cooking with a Thermos works great with freeze dried foods or
instant soups, but also works with grains, dehydrated foods or
even beef jerky!

Dehydrated food cooking.
Foods that are dehydrated can be easily reconstituted in your
Thermos. Use dehydrated vegetables to enhance your grains, or
make a soup.

Freeze dried cooking.
Did you realize you can cook your freeze food better in a thermos
than in those mylar bags you get with your freeze dried foods? It
turns out you can also make meals in your thermos from scratch.
Legacy Freeze dried chicken dices, right, can be eaten straight
from the bag, but they are great for creating your own dishes or
enhancing foods, like a veggie pasta or stew.

Cook grains.
You can cook steel oats and oat groats using a thermos, but try
also cracked wheat, or quinoa.

When cooking grain you must remember to leave room for
expansion (as with rice and quinoa, you'll need a 2:1 ratio).
That's one cup rice for two cups water or broth.

Cook with jerky.
When you reconstitute beef jerky in hot water you will get all the
flavors and really accentuate a meal. Try adding beef jerky to
soups, instant rice mixes, or vegetable stews, for example. The
list is endless. Check out below the simple rice meal...

Make a meal on the go with beef jerky!



















Above, a simple rice meal gets a little enhancement with beef jerky.

Be creative about what you cook in your thermos.
  • Beef jerky (add to your instant ramens, rice mixes and soups)
  • Dehydrated foods (like Harmony house) or your own.
  • Instant soups
  • Freeze dried meals (like Mountain House)
  • Freeze dried chicken or beef chunks (add to your soups and
    stews)
  • Mac and cheese boxes
  • Ramen noodles

Be creative in what you pack in your thermos!
Try these ideas:

Be sure to enhance your meal with something crunchy, like pilot
crackers.

Thermos is a brand name.
Like Kleenex is a brand name for tissue, many people don't
realize that Thermos is a brand name for a "vacuum flask" -- a
bottle with thermal capabilities. Thermal keeps stuff hot or cold.

Did you know a Thermos keeps liquids hot for 24 hours and cold
for 24 hours? Thermos vacuum insulation technology can help you
get maximum temperature retention, hot or cold.

Thermos has a rich history. Sir James Dewar, a scientist at Oxford
University, invented the "vacuum flask" in 1892, but it wasn't
made commercially until 1904.

Solar Thermos?
A Thermos-like technology is available in solar. The Total Survival
Portable Solar Cooker Kettle, pictured below, is ideal for boiling
and sterilizing water. It uses a high efficiency solar tube to
collect solar heat. The parabolic outer shell can concentrate the
solar heat to the inside of the cup.































Above, the Solar Kettle is light and ready to help you melt snow and
pasteurize it for drinking water. Use it anywhere there's sunshine.

Using only sunshine, you can heat 16 ounces of liquid in minutes
while remaining safe to touch. The Solar Kettle includes a vacuum
tube, two parabolic reflectors that hinge to protect the tube in
transport. This also doubles as a sturdy carrying case and stand.
Use the Solar Kettle in any temperature -- in snow or winds as
long as there is direct sunlight.

How to use the Solar Kettle:
Depending on the amount of sun, water in the Solar Kettle will
boil in 20-49 minutes! Here's how it works...
1. Wash the inside of solar kettle with soapy water before use.
2. Peel the protective film off the reflector.
3. Fill with 480ml water, soup, rice and water, etc.
4. Open of the reflectors.
5. Place on a solid surface with reflectors angled towards sun.
6. Reposition as the sun position moves if necessary.

While it's great for bugging out or backpacking, it's good to have
at home for emergencies too.

You will heat water at zero cost -- there's no electricity  or
batteries required! There's no more reliance on a gas, propane or
charcoal stove. You will use this anywhere there is sunlight.
Using the Solar Kettle you can easily make tea, coffee, noodles,
cook rice or sterilize water.

Happy endings...
Using a Thermos is a simple idea worth pursuing. Now you know
that a Thermos has much value in prepping.
