+VIDEO! Poorman's Boil: No propane, no electricity, no prob!
  • When the hose on my propane burner began to leak and the local shop wanted 30 dollars to replace it, I knew I should look for a more off-grid approach to the boil. About a year ago I came across this technology and knew I had to give it a go; enter the Rocket Stove.



    Here is the video I used to make mine. It's a very good instructional video. Each rocket stove is different based on the materials used and the diameter of your pot.



    A rocket stove uses small pieces of scrap wood in a limit oxygen environment to produce super hot, clean and very efficient combustion. The gasses are carried up around the pot and out the chimney pipe. This prolonged contact time with the pot allows for time to make thermal exchange. One of the many benefits of the rocket stove is being able to have a fire without worry of burning down the entire state. It releases next to zero smoke. The outer chamber never exceeds 280F.

    We've got likely 100 lifetimes of wood on the property here. We've also got an abundance of slab wood from the wood mill. These pieces work perfectly in the rocket stove.



    Wood stove construction. I went with a metabo whereas the tutorial guy used all hand tools.

    Vital stats:

    Starting water temp: 82f

    Outside temp: 88f

    Strike water volume: 35L

    Strike water temperature: 175f

    Time to reach strike temperature: 35 minutes



    You may recognize this pot from Korea. At nearly a 1/3 of the cost of a brewpot locally, it was worth all the crazy stares at the airport.





    The brewing session went on without any problems. The fuel needs to be slid down the fuel magazine as it's consumed about every five minutes.



    I'll post of video of the stove in action when I reach broadband land. It will give you a better feel of how awesome this SOB is. Until then, brew on!

  • Garrett = MacGuyver???
  • So awesome. I am looking forward to some video. This sort of DIY would never fly over here in big box apartment land.

    You'd be surprised. I built a mini rocket stove out of a gochujang can that we used to take up to our 21st floor for BBQs and smores.

  • S'mores...Seriously?

    When are you coming back to Daejeon? Sounds amazing!
  • That's awesome. I've been waiting to make one, but I haven't had a reason to make one in Korea. You can always use corn cobs as fuel too.
  • "waltonjones" wrote: When are you coming back to Daejeon?

    I'll be back next week.

    Coffee grounds, coconut husks etc. If you like to tinker or like to read about tinkering check out 'wood gas' or 'wood gasification'. A couple years back I had a small 5hp Briggs and Stratton running off of wood. It's really cool! I'll renew my wood gasifier pursuits next summer vacation when I have more time.

  • Thats freaking awesome. I'm gonna have to learn some metal working some time. Also, did anyone else immediately think of Aperture science when he said the name of his research group?

    I say go for it, man. I'm far from a tin knocker. This is something the average swinging dick can throw together with a metabo, some spare time and a few curse words.

  • G,



    That is pretty slick....nice work!

  • That's great. I'd love to make on here once I've relocated to a place with a yard. I guess it depends on where this 'mystical' place is with a yard and how available fuel is. My father-in-law has a saw mill, so at the moment I'd be awash in scrap wood!

  • that whole site is amazing...they have plans for a barrel autoclave and biomass briquette maker! excellent work man, it looks great!
  • "daxdefranco" wrote: .they have plans for a barrel autoclave and biomass briquette maker!

    Dax, I'm not sure if your into the whole alternative energy but if you are and you come across blueprints for a large chambered bio mass heater, please forward them onto me. Something that one could load up in the A.M and come back at the end of the night to stoke again.



    At some point, I'd like to build a vertical feed rocket stove surrounded by cob for prolonged thermal output. Cob + rocket mass heaters are a pretty amazing combination.

    I can just see somebody, perhaps Rob, with a 55 gallon rocket stove atop a 3 story villa cranking out some swill on his veranda in a small Korean town. It would be quite the sight that's for sure!

  • That's very cool.



    Okay, maybe a dumb question, but why does it not smoke? Is the smoke getting caught higher up, so that only heat vapor is coming out the pipe, or what?



    EDIT: Oops, dumb question, answered with Google's help. (Also here.)
  • I think I'm going to try a rocket stove from a soybean oil container. I think this would be perfect for the balcony.
  • @gord. It doesn't smoke because when implemented correctly the combustible material burns at over 650 degrees. At that temperature there is complete combustion so there is no smoke. It's a brilliant piece of human engineering for an alternative for fossil fuel and it cuts down on the indoor air pollution used in African households. I saw a documentary in which an African mother said she no longer suffered from headaches like when she was cooking with charcoal. And it's soo cool

    For general cooking purposes or brewing related?

    Yup, that's what the links I appended to my question suggested. :) It is cool, and I would love to set something like that up in a backyard, if I had someone that, you know, had a back yard I could use.



    Someday... maybe?
  • I've been reading a bunch about building an earthbag (superadobe) house here in Korea....very interesting stuff! Anyways, I can across this dude that built a rocket stove in his house.

  • There are a lot of people doing really interesting things with this technology. My favorites are the designs that incorporate a horizontal flue where the gasses pass under a cob bench. This as a a giant thermal heat sink that you can warm your ass on.

    Never in a million years would I have thought that a Korean would put this in his/her apartment. Wish I could meet this fella and buy him a beer. Impressive!

    I have a backyard you could use, Gord, at least for the moment, maybe a year or two, before the goddam government takes our house. I could get into this.

    ...why's the government taking your house?
  • I appreciate the offer but, being a lazy SOB, I'll have to do things in our own backyard. We actually have one, but plan on being here a limited amount of time.



    Why is the gummet taking your backyard away?
  • The guvmints takin the house so they can put in a "human town", put more people in the area and collect more tax revenue. The saddest thing is that just below our house lives is another house owned by a retired general, a man who presumably has given pretty much everything in the service of his country, and they're taking his house too. Pricks. :evil:

    I'm a little confused. When you say backyard, are you referring to your Korean backyard or your English/Canadian/American backyard?

  • Hahaha! My Korean backyard! U r confused bcos it is so rare! But I really do live in a house. With trees and flowers and dogshit and everything. I am a fortunate man.
