Before I get to the body of this post I’d like to say this. The reason you get to see more images from Ildi & Levente then from other producers is because we are neighbor. We would be happy to post more images from other produers and that is where you may come into the picture. If you enjoy photography and maybe even a member of one of our boxes and want to get a closer look at where your food comes from and want to share those images with others then please do visit with one of our producers, snap some images and send them to us … we will happily publish them.
I think that this year’s centerpiece is Levente’s improvised heating system. Initially he welded together an old stove box and boiler to heat water which is circulated through pipes which heat everything from plants to young-chicks:
Then due to frosty nights he added a hot air blower made up of all used parts: an old pump engine, a propeller from a broken down car and a radiator he found in a scrap metal shop in Cluj and a timer that switches it on and off (I think in half our intervals) so that the engine doesn’t overload.
The heated greenhouse is already home to numerous generations of plants, some of which will be transplanted into other greenhouses where they will grow and mature still protected from potentially cold weather, significantly extending the growing season.
One greenhouse is already filled with green – with plenty of spinach and soon radishes.
In addition to the chicks pictured above there are two mother hens busy taking care of just hatched chicks:
And continuing Levente’s metal-working season he has constructed an improvised power onion planter – which should transform a two week task into a two day task.
This winter there was a substantial group of members who continued to enjoy deliveries from Ildi and Levente (and other producer-families) throughout the winter. Now with a growing season starting earlier, the “production year” has expanded amazingly … from about 5 months in the first year to 9 or 10 months. Wonderful evolution.
We’ve played around a bit with natural finishes and we expect to do so much more in the future. We do have a good book on the subject but when this kickstarter appeared I knew I wanted in on it. For me, without access to hands on workshops, something like this is the next best alternative:
It had a good burst of interest in its first days but has slowed down and I really want to see this, so please spread the word 🙂
Sepp Holzer’s ingenuity at work. In constructing terraces he comes across a hardpan layer of clay. He lays about 100 of slitted pipes that drain naturally with the contour of the hardpan and those pipes collect into a cistern which is used to create head pressure for a house downhill from it. The terraces are forested, quality, naturally mulched and fertilized soil is built, that soil retains lots of moisture, moisture stops draining at the hardpan, meets the slitted pipes and becomes a spring … now flowing at 5 liters per minute all year long (regardless of climate):

When I started playing with rocket stoves the main resource available was the Rocket Stove book. Though I still consider it a must read for anyone heading into Rocket Stove territory, I do not consider it sufficient. It left me with many questions, it has some outdated information and some things that, knowing what I know now, are borderline wrong. Fortunately there is now an additional resource that complements it wonderfully.
Earlier this year we participated in two kickstarter documentation projects on Rocket Stoves. I’ll speak shortly about one and at more length about the other. The shortly: the Paul Wheaton 4 DVD pack is a nice to have thing. It was a huge success on kickstarter which made its production value all the more disappointing. It includes 4 DVD’s none of which felt complete and comprehensive (the Fire Science came close). It has low quality video and audio. It was nice to have a glimpse into a workshop with Erica and Ernie which I do not have access to … but it was an opportunistic production. With the funds it raised I felt there was an opportunity to create something much better … an opportunity that was missed. This kickstarter project felt incomplete and … well … icky.
Which brings me to the second production How to Build Rocket Mass Heaters with Ernie and Erica by Calen Kennett of Village Video. This was the first of the Kickstarter projects to launch and though it got fully funded it did not create the buzz that the second project got. It was delivered late (I just received mine a couple of days ago) but that was because loads of caring production work went into it.
It documents an entire build of one Rocket Mass Heater (the one you see on the cover) – an 8 inch system built over an existing wooden floor. It covers very many details which appeared as questions during my two builds and I have not seen addressed anywhere else, covering tools, materials, design, build and finishing. It has excellent quality video and audio. It is a composite of footage shot on site during the build together with a separetely shot and well thought out interview with Erica and Ernie (with excellent quality audio). Inside the DVD case there is a printed page with a list of tools and materials used in the build … superb attention to detail.
The kickstarter edition included Erica and Ernie’s recently published The Art of Fire (which I have yet to take in). In addition there was a surprise on the Kickstarter DVD – the detailed plans for the RMH in the DVD (which more than makes up for one thing that I believe is not emphasized enough in the DVD – an explanation of the basic structure of feed tube, burn channel and heat riser and their dimensions). It is a production infused with care and quality.
If you want to get started with Rocket Mass Heaters I would recomment the (above mentioned) book and this DVD.
Some weeks ago I made a comment on how salad season is coming to an end … it was prompted by the sudden disappearance of peppers and tomatoes.
Well since then I’ve been eating amazing fall salads. Spinach, salad leaves (when I can get them), chopped cabbage (red and white), grated carrots, radishes (when I can get them), onions make a splendid salad. Actually a salad I prefer over the summer salads – during summer I prefer to eat vegetables fresh cut into bit sized chunks … not salads. I’ve been eating lots of it … like an unplanned and oh so welcome wave of vital nourishment before the real cold winter sets in.
To further anchor the experience of abundance I find that no matter how hard I try I can never make a salad small enough for one person. So I usually end up with a “day salad” … that is a salad that I revisit twice or three times a day.
So, my apologies to the salad gods for an early dismissal and my thanks for these amazing fall salads.
There’s an interesting group called All Power Labs who research biomass gasifiers: in lay terms they make machines that can convert hay, wood chips, nutshells (a large variety of biomass substances) into clean gas products which can be used to power other things – such as a diesel engine generator (which they do). You can see this system at work here:
They got my attention because if/when we go off-the-grid we will likely need a backup source of energy in winter months – the simplest being a diesel generator. But that requires diesel. So the potential of a generator that can run on biomass of which we have plenty is pretty exciting and fills another gap in the sustainability puzzel.
Their CEO Jim Mason appears in a series of 3 videos (~2.5 hours) which finally provided me with an explanation on how burning works. I admit that parts of it were a bit beyond me but for the most part I was able to follow it and learn what actually happens when I burn wood for heat (namely 4 processes: drying, pyrolysis, gasification, combustion).
It refined my understanding and appreciation of what goes on inside Rocket Stoves. Most stoves or fireplaces are only able to burn ~20% of the potential energy in wood, most of the rest is released as gasses which for the most part escapes out the chimney unburned. A lose-lose situation: losing potential energy and releasing pollutans into the atmosphere. A typical rocket stoves will burn most (if not all) of those gasses – already making it 4 to 5 times more efficient then most wood burning stoves. Then, after a clean and efficient burn the heat that is generated is retained in a thermal mass … which easily brings them to 10 times better.
