Blocks crumble pretty quick when you heat them with fire. Long term, you are far better off with fire brick, and/or flue liners. They are made to stand up to the intense heat of fire.

For a quick emergency stove its not a bad iudea. I would try to avoid having to cut any blocks Remember in an emergency and there wont be any power to run a saw to cut the blocks. While this is true that the heating and cooling cycle will cause the concrete blocks to get brittle and crumble and fracture in a few weeks. It is a also true that most emergencies only last for one to two weeks. The concrete blocks will last long enough to meet the immediate need. They will last longer if they can be kept dry or covered when not in use. Also in some designs the blocks can be rotated around about once a week so the block that gets the most heat is moved to a cooler part of the stove. That will greatly extend the life of the blocks. The life of the stove could be extended for several months if a few extra blocks were kept in reserve. If I were going to build one for a hunting camp that would last for years I would as you say build it with bricks or bricks with a clay chimney liner. Looks like something that would be fun to play around with. Thanks for the video
@@johnndavis7647 This particular design is intended to be temporary. For long term use, tear down a fireplace chimney and use the fire bricks around the fire box.
I think that would work with only 3 blocks as well, and you could balance a big pot on just a few rocks on the corners. You could cook on it and even heat water for bathing. I lived in SE ASia for a year and we used a clay oven for EVERYTHING - cooking, tea, warmth, dishwater, bathwater, laundry.
👍👍👍for the nice, simple and easy to use rocket stove!We usually use those pine cones for fuels when i was young, i am from the Mountain Province in Philippines and we have lots of pine trees around so aside from the tree trunk, branches and twigs we used to gather the cones for cooking fuels too. We use dried pine tree saps to start the fire. That time we did not have electricity in our village that’s why we used all the time pine trees, not anymore this time because we have gas stoves/ovens and electricity.
For everyone talking about the blocks cracking or even exploding, granted over time this will degrade the block and create cracks. However if you are just using this as a chip fire to sterilize water and maybe heat up some food for one person then the amount of heat energy creates by such a small short term fire is unlikely to build up inside the block to cause such a dramatic explosion.
WW II survived, my house 12 feet deep flood we survived, 2018 hurricane Micheal, 2019 hurricane Retain survived... We must have knowledge of how to survive. I’m 76, easy & light work. Without big men help I can put together. Thanks showing this simple & easy rocket stove.
I'd be careful about trying to boil water or cook in most tin cans. I get it as an emergency use, but I think I will try to save some food safe cooking vessels. Nice to see a rocket stove made with fewer blocks. Makes it easier to prepare for when needed. Thanks for the demo.
I just got all the blocks today and cant wait to try it. I went with 5 blocks to see how a larger chimney works and a 6x8x16 as a base. I actually found a diamond masonary circular saw blade so making the special cutout block will be easier than trying to chisel and hammer and risk cracking the block.
It's not that hard to break a brick or block. That's what is so cool 😎 is how we can take an idea and add our own twist on it and learn from eachother. If we could all put effort into helping one another instead of competing with one another 💕. WE COULD LITERALLY MOVE A MOUNTAINS 🏔️ 🏔️.🙏📖🗡️⚔️🛡️✌️💐💐
Will boil a lot faster if you use a cover. I find mine at second hand or thrift stores like Goodwill. A paint can also makes a nice system too. New clean cans available at most large paint or big box home improvement stores.
One must keep in mind that most tin cans, unless specifically made for food use, have a soldered seam. Most solder has lead; plus, an acid of some sort is used as a solder flux.
This blocks WILL CRACK ! I have played many times and they all cracked at one point. Fun for one time OK, but not long emergency need. Surviving (short term) maybe. In any case we had fun with this center blocks in all kind of set ups. There is many ways to do it. You don't even have to have the "L" shape. We even used three center blocks stacked on top of each other and 3 red bricks for legs and fire was just intense as "L" shape rocket stove. HAVE FUN !
Y usando todo el bloc sin partirlo se puede elaborar doble parrilla haciendo primeramente su base plana dejando sus orificios libres para que pueda subir la flama hasta se le puede adaptar un tubo de fierro para el escape del humo; entre los blocks de altura se puede instalar una rejilla de quitar y poner para carbón y finalmente sus parrillas que tal. Gracias por compartir saludos.
Fur cones burn and the place was littered with them, use what's to hand as my survival instructor told us. In fact I used to collect material en route to camp. Sticks, fur cones, grasses that are dry, bark & punk wood. I might also have some kerasine or Vaseline covered cotton balls or pads in a tin. Potassium permanganate and glycerine to light my fire, ferrous rod and steel or just have a few bic lighters on you kit. I keep an emergency kit, upstairs and downstairs of my house. A brew kit of powdered milk, t bags, instant coffee, sugar and or cookies/biscuits are good for moral and energy supply.
I believe the taller chimney is better. It makes more draft and it provides more area to complete combustion. As it draws harder, more air is blown into the fire, thus making it hotter, Right?
I have several old concrete driveway culverts, tried one for burning trash. NOT ! Cracked 2 or 3 places and fell apart first use. It was 12/14 inch x 3 ft. Porosity and make-up of the concrete has a lot to do with it, fire brick is just special. lol The incinerators I have seen in alleyways out west were made of concrete, so the type of concrete used obviously makes a difference.
Mindless foolishness using concrete blocks. Concrete is a chemical hydrate which means it is held together by water molecules. These water molecules are released under high heat - sometimes with explosive results. Every mason knows to use firebrick in any area subject to solid fuel heat. Anybody using concrete blocks around a fire is a fool. This stove is not something really fantastic with a gee whiz name like "rocket stove". This is merely a well ventilated solid fuel stove
Survival Common Sense -Well I was kinda hoping to purchase them separately and not the whole stove to get one part. But I get the point, I will need to go to an appliance parts store. My stove is an electric flat glass top. Can’t borrow from my inside stove
Your purified water is escaping as water vapor... Should devise a way to capture that water vapor because that is distilled water, true purified water.
Very cool! (Wish this was up the other day I just ordered a bio mass stove lol) but still good if out and need to make one like in a disaster .... I found the frog interesting too... very brave to be that close to you and and the fire there last part of the video.
Junk food; potato chips, top ramen make good fire starters. So I've heard. You can pour antifreeze over the top ramen. Or take lint from a clothes dryer. Put it in egg crates and cover it with melted wax. Another great fire starter.
I hate the blackening of the cooking pot. There has to be a way to separate the pot from the smoke, like say a thin steel plate wider than the pot placed under the pot on top of the stove.......just thinking.
If you build this on the ground you can use a 2x8x16 top cap cinder block or to get up a little higher a 6x8x16 for the bottom. Would it burn even better with an additional block on top so as to have a deeper chimney ?
Stove cement blocks will/can explode like a hand grenade. Happened to me.That’s what took out the two little bunnies in the background,but the frog seemed to be alright.Be careful.
Would this work a metal sprinkler head with carbon felt rolled up and placed inside with the female water connector having a copper pipe with a screw cap on the end designed to stick out the side of a rocket stove so you can fill it with alcohol with the sprinkler head being just above the air intake to the chimney with a little bit of paper to start the rocket stove by heating the sprinkler head eith alcohol vaporizing the alcohol with the up draft for a very hot very clean burning flame to boil water very easy? Just thinking of a way not to have to use wood or some other fuel source.
I see you asked this question a few years ago and didn't get an answer. Just in case you still need it, it's a faro rod, harbor freight sells them for a buck or two. It's a metal piece with a razored edge and a stone. When scraped over it throws a spark that lands on your "material" for starting a fire...a cotton ball is great.
@@cek7940 Wow, yes that's a long time! Thanks for your response. I had forgotten about the half blocks. I appreciate you getting back to me. I can view the video again. Hope you're doing well thru the pandemic.
I bought that three-sided brick. In any wall, such as one demolished in a disaster, there will be similar bricks. Otherwise, some careful tapping with a hammer could break out one side.
Survival Common ty for reply. Sense ive tried makin a stove with a half brick that was sort of a jagged edge and it didnt work. It didnt vent right. So i would try to buy one of those if they come that way😊

Your purified water is escaping as water vapor... Should devise a way to capture that water vapor because that is distilled water, true purified water.
edb strung not trying to purify water... Just kill off harmful critters
just put a pan cover over it
Distilled water is dangerous for drinking long term !!!
Drinking pure h2o is bad for you? Ridiculous.
Yes and if you distill it a dozen times it is even better? You don't get the minerals you need from distilled water.

What was that rod that you used to start the fire? It was pretty cool.
I took about 10 or so bricks and made a rocket stove in 90 seconds. Worked great - made skillet popcorn.
It'sa great design!
good work.. a collar would cut the wind ..a cake ring or two skirts cut from a #10 can or any 5 gal bucket..
How do you cut the concrete if you don't have a concrete saw?
Half blocks are typically in a wall somewhere. You just need to find them.
Thats awesome Jack!
Water only has to reach a temp of 140 to be considered safe to drink. Boiling is a waste of fuel.

Hollywood A stove or true rocket burner.
Smear the bottom of your pot with kitchen bar soap or liquid dish washing detergent and the soot will not collect. It works well.
Brilliant! Thanks for posting!
Are the two base blocks open at both ends? It would have been nice to see both sides and not just the front.

Do the bricks crack ? Like when you use regular bricks ?
Over extended use they might. If making a permanent structure, use fire bricks and cover the stove when not in use.
