    Default Emergency improvised heating and cooking

    A quick reminder to everyone stocking up now. Consider that you might very well end up cooking without electricity. What you invest your money in must be pretty easy to cook. The ratio between fuel for cooking/ net prepared food must be in balance. Thers no way you will be able to soak and cook kidney beans or chickpeas (wich also requires some extra amount of water after soaking, since soaking water is to be replaced before cooking) without lots of energy consumption. Brown rice with husk still on? Not very likely in a shtf scenario, its 45-60 mins cooking at least.
    To conclude:Water and fuel for cooking & heat could be scarce
    Be prepared for the worst and hope for the best

    A small pressure cooker, water filter and small wood fired (outside only) camp stove may be very helpful for cooking beans quickly.

    How do you cook your rice or oats when the power is off and your camp stove is out of fuel? Consider a rocket stove, there are many kinds and the brick type is one of the most simple to build. You can even make them with large #10 restaurant size cans for home or camping. A big reason for rocket stoves is that the fuel is minimal, usually just twigs you can pick up.

    There are also indoor rocket type stoves for heating and cooking. Do a search on YT for the many kinds you can build.

    for an improvised stove in nature, all you need are some rocks, wood and *fire. you could use any can or pot to cook. There is a lot of videos out there, many different ways to archive the same thing, I would go as simplest option as possible.
    if you are in survival mode you will see how many ideas will come into life. watch out for the weather in your area, raining means in general no cook in the open!

    * i have a zippo about 12 years old, it is a great fire starter and easy to carry, also i have parts (basically flint stones and wicks) to replace when needed, 1 litre of kerosene (for the zippo only, not for the bonfire, otherwise it will impregnate the smell in your food ) will last long time depends on your usage.

    Yes, true! That will happen with any stove for sure whether it uses LNG, electricity or other fuels. You can stock up on bottled fuel as well as sticks, lumber bits, twigs, pine cones, leaves and more and continue to forage here and there as you go about your day. It is the same as for a fireplace, one looks ahead and continually adds to the firewood pile.

    There are many different kinds, if you're interested do your research and build or buy the best one for your situation and enjoy your hot lentil soup.

    https://gearhose.com/best-rocket-stoves/

    Quote A rocket stove is an efficient, wood-burning stove that can produce clean, high-temperature combustion while using dry wood twigs, branches, pine cones, leaves and other biomass as fuel. (Some camping and survival rocket stoves are also advertised to work with charcoal, but that is not the primary fuel for such stoves).

    Rocket stoves are considerably more efficient than other wood-burning stoves and cheaper to use than large propane or liquid-fuel stoves because of almost negligible fuel costs. Rocket stoves are available in different designs and sizes ranging from small 4-5 person stoves to large 8-10 people stoves.

    The simplest rocket stoves used for camping and survival, have a simple J-tube (or right-angle, L-tube) design, as shown below. Once the fuel is lit, the fire burns sideways because of the air draft. This air hits the back of the stove, creating turbulence and providing secondary combustion for the fuel. Because of this bottom chamber, the pre-heated air combines with the secondary combustion to create a clean, super-hot fire.
    This would be more efficient than the one I posted above but is a bit more complicated to build:

    Don't depend on gas bottles, in a rush they will all go.

    Rocket stoves can be home made and use the smallest of twigs to run.

    Quote Rocket stoves are easy to make and super efficient wood burning stoves that you can use for camping, homesteading,survival and more. Here are 8 ways to make simple rockets stoves at home using wood, bricks, metal or even dirt. Along the way I will also give you tips and tricks to using rockets stoves.

    I am sorry for the whole situation, especially for children who should not suffer.
    I come from a country that 30 years ago had no heating in apartments. I grew up in an apartment without heat, until I turned 12; and I slept dressed in wool and covered with a quilt made of goose feathers.
    Wool is important in socks, sweaters, hats, cotton as well and linen is essential for clothing in such a cold.

    Where I have lived for over 20 years, I have no gas at all, because no one invests in gas pipelines or district heating networks in the area.
    Wood-fired boilers are also dangerous because I frequently run out of power and then the water circulation pump and the air circulation motor stop working forcibly.

    So we have a wood-burning stove, built of bricks (passed through the wall to heat three rooms).
    I also have an electric boiler and a gas cylinder for the oven.
    But on the wood stove with natural air circulation, in case there is no more electricity, it can be used at any time, water can be heated, food can be made and the living space is also heated.

    If there is no wood in the area, briquettes can be made from cardboard garbage dumps (we picked up in a year from all the supermarkets that threw tons of cardboard, and now we light the fire with them, I think we have a stock of 10 years) . The press for cardboard briquettes can be made at home if you find a hydraulic car jack, we made it ourselves.
    Also, if there are still bricks to buy (and we don't have to make them ourselves) (refractory bricks are even better), a stove can be built by two people in a few hours, even in the apartment. There are many construction models and it can be built as desired, but in proportion to the space to be heated.
    I know you need permission, but maybe in extreme cases the authorities could allow ... the construction of the stove.

    There is also the option of charcoal for burning (if they are to be bought cheaply) or any straw from the plains and in general anything can burn in extreme cases.

    You can buy meat and keep it in salt for two days, after which it can be spread somewhere on a wire (on the balcony) in the wind for maturation, if it cannot be smoked (for a long storage of at least one year). Bread can be made at home in the stove oven, if you still find yeast and flour.

    However, a stove made of bricks helps with food, heating and washing (if you gather water resources).Meanwhile Billy mentioned the wood stove above, until I managed to translate into English what I had to say.
    It should look like this, but there are many models.

    And all this to be just human.

    I examined this the other night and I do think it works but that a tin aluminum pot insulated with a fireproof insulating material would be better. Since aluminum heats up quickly. This system works by providing a bigger combustion zone for the longer chain hydrocarbon to burn . It traps the paraffin fuel in the hot zone so it can burn more thoroughly. Maybe an alum pot inside a clay pot then another insulating material on top of that would work best. A tin can inside a clay pot can also be used.What we wanted to accomplish is to make the inside lining reach the combustion temp. as soon as possible and retain that heat.

    This may be helpful to someone, though you would need dry twigs and slivers of wood for it - how to make a soup can stove.

    Seeing as the flame is pretty high when it initially gets going, maybe it's best to use under cover outdoors and well away from anything flammable, such as in a garage.

    Hey Bubu.

    I have a candle furnace I made years ago. The way I made it is I fitted four clay pots one inside the other, like those Russian dolls. One small candle placed inside this arrangement heats up first the inner pot. Then the heat escapes around the bottom edge, only to be captured by the next pot, and then the next and the next. It is highly efficient. One tea candle will boil a bowl of water on top and heat a small room easily.

    I used some steel connections to keep the pots together, with a large bolt that runs through all the pots to allow for heat transmission upward. If I knew how, and it wasn't such a hassle, I would provide a picture...

    Hey Bubu.

    I have a candle furnace I made years ago. The way I made it is I fitted four clay pots one inside the other, like those Russian dolls. One small candle placed inside this arrangement heats up first the inner pot. Then the heat escapes around the bottom edge, only to be captured by the next pot, and then the next and the next. It is highly efficient. One tea candle will boil a bowl of water on top and heat a small room easily.

    I used some steel connections to keep the pots together, with a large bolt that runs through all the pots to allow for heat transmission upward. If I knew how, and it wasn't such a hassle, I would provide a picture...
    Hey Ernie, I still dont see the benefit of stacking too many pots. I have not use one you said it works, so probably I am missing something about pots. One thing I am sure is that it burns bigger portion of the hydrocarbon chunks which translate to more heat. Hydrocarbons are much like charcoal chunks there are small medium large. You can guess correctly that small ones burns up sooner. Thats more like the propane. When it comes to bigger chunks such as wood gas " the bigger the burner the more efficient it is" every wood burning expert in the world knows this. They just missed the WHY? its because HC molecules ones liberated it flies away quickly if you have a 6 inch hot zone that molecule can be a fourth consumed if you have a 6 feet hot zone that HC could be 90% consumed before it exist the hot zone. This is the same concept I had when I designed the steam injected burner I believe I shared here before. You may find them if interested I have explained there how it works and yes it works like a charm. Most probably more than 50% wood savings. Its actually the same concept big comp. employ to produce propane and a variety petrol products. Its called steam cracking. Its also the same reason why they dont want you to pour water on oil fires. Water turns instantly to steam and reacts with oil particles to make smaller and more volatile particles. which would result to... you know what. The same concept when I created the oil and water stove 14 years ago. Of course science and wiki had a different explanation.

    No argument there, my friend. You're the expert.

    The point of this arrangement is that the heat load is trapped in the dense material of the pots. And because there are several chambers, most of the heat cannot escape before it adds its heat to the mass. One candle like illustrated will burn for six - eight hours, maybe more. It can also be used indoors.

    I would have to look it up but this is paraffin wax, so maybe the molecular chain is shorter? In either case, it is extremely efficient, both as a heater and as a means to cook when the power goes out. It can be assembled in a few hours, costs next to nothing, is clean (no smoke), and the fuel is compact and easy to store. It also has the added benefit of throwing off enough light to read by in the dark.

    There is one thermal property of materials which is "emissivity" https://en.wikipedia.org/wiki/Emissivity. There is a good chance that clay pots has a high value. though I can't find any confirmation of it. If it does then it explains why your stack up pots works best.

    Found it the value is 0.9. So while the pot has a low thermal conductivity whatever heats it absorbs most of it is given of as radiation ,It goes in all direction. Instead of being carried away by air up to the ceiling. So yes you right your stack up pots is best. Brilliant invention again with the humble clay. There is also a pot in pot cooler.
