How would you waterproof it? I see a lot of light coming through the roof?
I just read a post on a book about grid beams.
Grid beams are an interesting idea, but don't know how much practical it is in reality.
THey are cheap, easy to understand, can be assembled in various shapes and forms.
In theory it sounds really nice.…

Hi Sasha,
I've tried using the reset password function, but it doesn't work (I never get an email link from globalswadeshi.net).
Would you please tell Vinay that there is something…

- Thanks Sasha for contacting Vinay.
Do you want my really crude drawings and the BOM spreadsheet?
I can send them to you via email... but I'm not ready to share until I clean them up.... I really want to work on creating the same plans with 100% non-store bought items so people with out funds can have a good life.

Reinder van Tijen said… - Yes, yes, you are double right. I got Marcin's name from you and yes I am interested in meeting the right people in Kenya.
What I plan to do there is finding out a working procedure for addressing schools to promote the Hy2U-handwashing device (http://www.hy2u.org). That will be: go there, demonstrate to teachers and kids, organize workgroups from parents, males to do woodwork, females the sewing, children putting stuff together. Drivers: make it beautiful, fun working together, the bacteria story only in the side line, YES comfort and decency.
This at different schools to get video footage for an instruction movie. Same for the NightReader, the little reading lamp for studying.
To come back to Kenya should be for urban sanitation specially, also for rural sanitation. Soon I will be ready for sanitation and water pump pilots. Extra eventual interest for other Demotech design is that could lead to application on a structural scale.
I'll go the 3d of June, travel back the 29th.
Thanks for organizing a contact if you judge it relevant.
Greetings, new friend Sasha!

- Yes, true, Sasha, long time, but I did not forget you and am happy to meet you here again, this time with a picture. All is well here, moving slowly. Hy2U for hand washing and a updated version of Demotech's rope pump are at the core of activities. I go to Kenya next month, will be here this summer, autumn will take me to Ethipia and Guatemala. A very good prospect.
Could you check out http://Openfarmtech.org/ ? I expect it is your kind of thing.
Greetings, Reinder

We must keep in touch. I hope beehives will feature sometime - but anyhow we have other shared interests too.
BTW - it was a pleasure to meet your wife.

- The best and shortest article is one on the Missouri designed masonry stove. cant help you with the actual rocket stove as I have never built one. But with the masonry stoves the basic principle is that every next chanel should be with 30% lower volume than the previous chanel. This is a rule of thumb but here traditional stoves don't really follow the rule and still work nice(more or less). I dont know where is the hotest spot, I sadly dont have any high tech equipment for measuring temps, but it is hotest where the flame is brightest, the whiter the flame the higher temperature. i know this is not much of information :)
If you are serious with this then you should probably build one and get some cheap temp measurement instruments. That shouldn't be very expensive in states. I live in Serbia.
Is your stove for melting metal or heating or cooking? I am not sure it will do all things efficiently, but maybe I am wrong.
What I know is that in these stoves I built after some times and if you fire them at high temps the grate which is made by casting iron get melted and dammaged sometimes, so I guess there were some really high temps involved. This is 1150 to 1200 °C according to wikipedia.
Regarding what is the most important part, hmm, not sure, I have built mine as good as I knowed since this was for friends and customers, and I didn't want any problems later. basically I think it is really simple if you know the few details needed. The chimney should be high enough (good draft) you should seal it well,don't make too much chanels (IMHO), dry it slowly, build like an artisan carefully and with love and it will work like a charm.

- Thanks for your reply.
Was there a single article when gave the best physical relationships (for instance the cook stove version requires the flue/combustion chamber be 1.5*({ength of the throat}).
Yes, I'm interested in melting down tin, iron, AL, nails, screws -scrap from our current society. Do you know where the hottest point is in the rocket model? ...and have you ever taken measurements inside at different points. Yeah, I know the stoves are sealed up, so it would be pretty hard for you to have done that, but it's data I'd really like to have.
If we knew there was a specific point in the rocket stoves which reached, say 1800 degree F, then one could build a crucible into the rocket stove in such a way that when scraps were put into the crucible, they would melt and flow out yet another access hole.
My fear is that both the crucible and the molten metal drain hole would leak heat out of the rocket stove, drop it's temperature, and complete combustion of the gases would fail thereby dropping the temperature at the hottest point..
Could you tell me what details you have found to be the most critical details, such that, if you fudged them just a little, the consequences were monumental (in regards to building rocket mass stoves)?

- Hello Sasha,
I'm beginning to spread the original plans for the cooking rocket stove...
I've built the cooking pot rocket stove in primitive areas with stone and clay/sand/manure for sealant... I've never built the rocket stove mass heater.
Do you have a pdf with the correct relationships drawn for the mass heaters you can post for me to download?
Also, have you ever seen a rocket stove used as a foundry rather than a mass heater or a cooking pot stove? I'd really like to see it if you have!
