We are off to a late(r then I would have liked) start this year. This was primarily because of my allergy and a very rain season. It was also because we got stuck with the roof!
Our primary plan to make a roof out of acacia vigas was deserted when we failed to source logs. We tried using some logs we had lying around. When we did … I stepped back and felt a clear “no” … I felt they were not uniform enough to build a good roof.
I then decided that we would use standard (easily available) soft-wood boards to create beams (charred to preserve and protect them).
… and after we got the beams onto the large room and sat inside it … we felt the structure gained a whole new dimension of life … the shadows were striking:
Beams now stretch across the entire structure and are ready to take on a roof.
We’ve decided to conduct an experiment:
- The roof on the large room (intended to be dry) will be built using the same standard soft-wood boards.
- The roof on the small room (intended to be a moist room to store root vegetables) will be made of small acacia logs (long-lasting and rot resistant).
And so we embarked on a first-of-its-kind-for-us adventure into our small acacia forest to cut down some trees (while thinning a dense and overgrown forest). I thought I’d seen this car do everything … today it did this:
Tomorrow ad midnight a group of 21 Belgian youth are arriving at our village to spend 8 days with us (that may be more than all the people I’ve met face to face and interacted with during the last year!). If the weather permits (we’ve had a very rainy season), by the time they leave, the roof will be complete and the walls will be covered with an earthen finish and we will be ready for the final burial (so that the structure will no longer be eroded by the elements).
Let’s do this!
We finally decided to go ahead and rebuild our second rocket stove (the one in the living room). My primary wishes were to rebuild the core (better) and to convert the relatively useless mass into a (small) bench. Iulia decided to make it a workshop and … 3 interested people showed up.
During the first day we settled into being together. I left the existing rocket mass heater in tact so we could review its shortcomings together and learn from that. We talked about the basic workings of a rocket stove while talking about the existing stove.
… and then we took it apart:
We had only one wheel barrow of waste which was non-toxic and we dumped it as back-filling at the earthbag cellar.
Though there was some soot in the rocket (sometimes it didn’t burn completely clean) there was very little of it given that it worked for 6 winters. There was a 1cm layer of light and fluffy ash sitting at the top of the heat riser (accumulated over the same period of time).
Until we reached the brick platform upon which the rocket was built.
We then layed out the expansion of platform for the new rocket.
… and started building it … giving everyone their first experience at working with mortar and laying bricks.
The next morning we finished it!
With the platform done we built a mockup of the core (while learning about dimensions and sizing using standard brick sizes) and its place on the platform (and relationship to the bench).
We then settled into a rhythm in which two people were laying bricks (one working on the core, the other working on the bench) and two others were preparing soil for mortar and cob (and doing other support tasks such as cleaning bricks so that the brick layers could work smoothly).
As the chamber that is under the bench started to take for, I figured out how we were going to close the top of the chamber (close from the chamber that makes the bench. The plan I came up with involved recycling two concrete slabs we had lying around together with some bricks. Next I had to figure out how to create a structure that could support that top while allowing a good flow of gasses through the chamber itself. It was a bit of a puzzle but we solved it.
… and the core was rising up
… and the chamber was rising up … and we were starting to apply cob (especially on the back side where access would become more difficult as the construction grew):
… and I think this is where we finished up on day 2:
On day 3 as most of the riddles were behind us and everyone had a better sense of the materials and the work, progressed flowed and accelerated. The core was completed and the chamber layout finalized. While the chamber was being closed up the heat riser was growing.
Pretty soon we were insulating the core with perlite in a clay slip (recycled from the previous rocket) in the chamber built around the core:
… and then the insulation sleeve around the riser was put in place (recycled from the previous rocket) … and also filled with perlite:
… and finally the barrel came on (for the last time – we had quite a few fittings), we sealed all around it with cob … and lit the stove … and despite adverse conditions (a new rocket filled with moisture, on a warm summer day) we all smiled when we saw the flames getting sucked into the rocket and the dragon came to life. Very soon we were in an overheated room with a warm bench (that nobody wanted to sit on).
… in the excitement (and a bit of rush to accommodate the schedule of one of the participants) I missed taking a picture of the barrel on the “raw” rocket … but the next day (today!), with Liam’s help preparing soil and mixing cob, we were able to get much of the cob work done (and we may complete the rough structure tomorrow).
Even though it is using the same floor area as the previous rocket, the footprint of the new build is much larger … and it dwarfs the room … which feels a bit off. That is a price we’ve paid for having a warm bench to sit on (without taking on a much larger renovation).
It was an intense weekend. I’m glad to have had an opportunity to share rocket stoves with Tudor (missing from the picture below because he had to leave before we took it) , Dan and Liam and Iulia. I’m glad to have a good core with hopefully a comfortable bench for next winter.

Our rocket-stoves journey
We have a journey of rocket stove building at Bhudeva… first it was the first rocket stove (bedroom, 2011), then fixing it (2012) then the second one (living room, 2012) and rebuilding the first one (2014).
We cook food and bake on both rockets most of the winter time.
It’s time to try a next step – we are going to rebuild the one in the living room, this time we are going to make it even more efficient and add a heated bench for two on it :).
We are open to make it as a mini-workshop where you can come over and learn by doing.
We will be building a rocket stove with a small mass attached to it and a place for sitting / reading / resting. It will be an opportunity to learn what were the limitations of the previous design (and why they were introduced in the first place) and the considerations that went into the new design. We will be building a typical rocket core with an attached brick chamber with some cob to add more mass and bring it altogether. It is a tight design that will fill a tight space.
You will have an opportunity to:
- Learn about rocket stove design,
- Participate in all stages of construction,
- Meet the materials and the tools involved,
- Spend some time at and learn about Bhudeva.
All within the settings and limitations of a traditional Romanian village house.
The build/workshop is estimated to take place in 15-17 of June 2018. The workshop time is Friday (half day), Saturday (full day) and Sunday (until 16:00). If you’ll join us, please arrive sometime Friday until 13:00 (so we can have the second part of the day for working).
There are 5 places available for participants. Sleeping will be in tents (there is plenty of space). The price for the workshop is 540 lei / participant. We are asking for 200 lei in advance (bank deposit or transfer), when registering, for booking your place. The rest will be paid cash at Bhudeva.
Please acknowledge that English is the communication language at Bhudeva.
We are assuming you will want to stay at Bhudeva, however there may be other options one of which is a new pensiune just outside the village (a few minutes drive) which has recently opened its doors to visitors.
If you do choose to stay with us, here are a few things you may wish to know:
- You will be camping in a tent (that you need to bring with you). We do not yet have built structures to house other people. We have one small house which is a private space and we prefer to keep is that way, for now.
- We have one composting toilet in the house. If you stay here for a few days or more, you will learn not just to use it (make contributions) but also learn to care for it (emptying it in our humanure hacienda).
- We have a small outdoor kitchen. We are inviting you too cook together or, if this doesn’t suit you, please bring your own food. If we will cook together, you are invited to bring with you some of the next produce: “bob lung” rice, spaghetti pasta, avocados, honey from verified source (we’ll coordinate this by email).
- We eat mostly vegetables and fruits, with some dairy productions and eggs. Most of it locally (in the village) produced.
- We intend to be doing everything together: working, cooking, cleaning. We’ll see how this flows.
Visiting Bhudeva, you are going to encounter also our solar dryers, earthbag cellar (we are now at the green roof preparation), hugel beds, solar panel or other things we play with and experiment here.
If you’re interested to partake please write Iulia at iulia [dot] sara [at] gmail [dot] com… in English and include your phone number and the questions you want to be answered before coming to the workshop (and maybe during the workshop, if you already have something in mind).
Iulia and Ronen
Last winter we witnessed 24+ hours of water flowing down our road … millions of liters. The sound of running water was beautiful but the sight of that water escaping was sad. It caused some damage to the road leading up to our property.
It was, I believe, a result of a wet season and years of over-grazing higher up in the valley (causing lack of vegetation to slow the flow of water and reduced water holding capacity in the soil).
When I talked about this with someone in the village he explained to me that it was my responsiblity (as the owner of the property) to build water ditches alongside the road to divert the water flow + “we’ve been doing it like this for generations, and there’s never been a problem!” It was as if he didn’t hear me … I could not find a way to show a deeper chain of causality where choices that we make upstream in our ecological cycles have downtstream effects.
Today I came across this video and wanted to make a note of it as evidence for future reference:
A house that was built in the late 80’s using Christopher Alexander’s Pattern Language … how sweet to hear the talk of simple, natural, real unfolding:
“there was never a real set of plans … it evolved and its part of a philosophy, you wait until you get in the context and then you decide … does the window go here? does the windo’ go there? … its real easy on a drafting table, miles from the site to go ‘ok, we’ll put the window right in the middle’ … but when you get there you go ‘lets see, riiiiight there’s the view'”
Lars and Robin are a beautiful couple I’ve had the pleasure of meeting a few times who live in Alunisu (on the other side of Cluj). In this interview Lars does what he does so well … gently and compassionately painting a comprehensive picture of where we are and where we can choose to go from here.
