  • In the aftermath of a disaster, purifying drinking water may be a priority. The quickest, safest method could be boiling. This biomass stove only requires four concrete blocks, a tin can with both ends cut out and a gas stove eyelet top. The completed stove is sturdy enough to hold a several-gallon container of water, stew or a heavy cast iron Dutch oven.

    👍👍👍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.

    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.

    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.

    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.

    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.

    Would it burn even better with an additional block on top so as to have a deeper chimney ?

    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.

    • @criticalreasoning2129
      @criticalreasoning2129 7 лет назад

      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

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.

    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.

      Yes and if you distill it a dozen times it is even better? You don't get the minerals you need from distilled water.

    Hi. what was the tool you used to light the fire?

      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.
