If you happen to be visiting this blog these days you may find it to be a but … confusing? unclear? There are two things we can offer you to introduce some clarity.
The first is that you read our About page – that may give you a picture about where we want to go and what Bhudeva has to do with it.
The second is to understand that we are doing a lot of waiting grazing – it’s a great word/idea/inspiration I picked up when I was working as a photographer with improvisers. It draws inspiration from cows – they just do what they do (and they do it almost all day long) … and it works. In improvisation Grazing describes a state in which you are already in performance and yet you feel as if you have nothing to offer. When that happens and you realize that you are grazing for material then the grazing itself becomes the material. It can alleviate tensions that comes from thoughts like “I have nothing to do but I need to do something” and almost instantly transforms you into a space of doing … the doing of grazing.
We are currently in an apartment in Cluj and we have this encompassing vision of where we want to go and we aren’t sure how to get there. The most actionable task in the Bhudeva context is finding some land and a house in our vicinity. We are in the process of doing that but it isn’t very interesting and worth noting (yet!). So the rest of the time we are grazing, imagining that we are in our house and asking ourself what next? What you currently see on the website is an echo of that process. We are getting flashes of images of our house, making our own yogurt, baking our own bread, exploring ecological and sustainable building and agriculture … we are passionately pursuing whatever arises from our grazing.
On the face of it, it may not make much sense at this point, but under the surface it’s brewing ever so gently into what we believe will fill the rest of our lives. So stick around … with all this grazing we are bound to start squirting some delicious milk 🙂
My recent hemp-harvesting information tour through the internet brough me to BioRegional. I don’t yet have a clear picture of what they do or who they do it for, but as I was going through their website I came across one of their projects nicely described in this video:
I loved the separate garbage bins integrated into the kitchen design (though I love even more the potential of no garbage in a village home)… and though I don’t know what they do – the colorful ventilation thingies are interesting and beautiful.
I am currently living with an inspiring notion that we will (1) be able to grow the hemp needed to build our future home and (2) that we will have enough land to grow a houses-worth of hemp every year so that someone else will be able to do the same.
Though I have to say that the more I explore the world of Hemp the more doubts about this being a feasible goal. At the end of this post you will find some links and PDF’s I read and that led to my current understanding.
Hemp seems to be a relatively easy crop to grow. It’s strong, it doesn’t require pesticides, it grows pretty fast (~4 months) and it even renews the land in which it is grown. The more substantial challenge is harvesting and processing it.
Three Parts of Hemp
There are three parts to the hemp plant – each with it’s own uses:
The seeds can be used for all kinds of food products, oils and other medicinal by-products.
The fibers have all kinds of industrial uses (from clothes to cars) – they are the middle layers of the stalk covered by a thin protective layer.
The hurd – the wooden core that is left over after the fibers have been extracted – which is the part popularly used (together with lime) for construction (although I have come across information that indicates that it is possible to use the fibers and curd together for construction – which means that they don’t need to be separated).
Some Hemp Harvesting Facts
Seeds and stalk don’t mature together – they are (or at least should be) harvested at different times. Both the seeds and the fibers have (different) optimal times for harvesting – beyond which both lose some of the potency and qualities.
The seeds don’t mature all at once – they tend to mature in two cycles. Harvesting time is when you think you can harvest the most mature crop (when some of the seeds may have decayed or lost their potency and others still not quite matured).
Hemp is a tough plant – so you need resilient and strong harvesting tools. The strength of the fiber means it’s hard to cut down and the length of the stalk means it will catch on to and jam any moving part it finds (for example – combine machinery) – which means that you either need powerful harvesting machines – or that harvesting may be slow and tedious.
Hemp is a tall plant (much taller then wheat or barley) – which means you need harvesting equipment that can reach up high.
When the stalk is cut, it is useful to do it in such a way that it is then easy to collect into bales – if I understood correctly what this means is that the harvester needs to leave the cut stalks uniformly oriented on the ground.
The stalks should be cut as long as possible – long fibers are generally better and more useful then shorter ones.
It is possible to harvest both seed and stalk. Seeds go first (duh!) – but then you not only need tall harvesting equipment but it also needs to be sharp and fast spinning – so that the stalk is cut cleanly – leaving long fibers in tact.
The primary processing for seeds is removing them from their shells – I still don’t have information on how that is done.
The primary processing for stalk is separating the fibers from the wooden sheathe (this is called “decortication”- whichI am guessing comes from the idea of removing the core and, apparently, originates from a medical surgical process of separation). There are numerous methods for this – but generally they seem to be divided in two: industrial processes and organic/natural processes. I am less interested in the industrial aspect so I focused a bit more on the natural processes. Apparently the idea is to use water to cause decomposition of a kind of “glue” that keeps the fiber and curd attached. Usually natural dampness like dew will do the trick. You need to keep an eye out on the crop until separation begins – then you need to let it dry for a few days. I am not yet clear on all the details of this process.
All these facts seem to eminate from an industrial/financial view point. They are focused on creating optimal yields and financial returns. If harvesting and processing hemp can only be done using heavy and expensive machinery – that means that growing just a few acres or a hectare of hemp isn’t feasible. I was somewhat discouraged by this. But …
Since hemp has been grown for hundreds of years (if not thousands) I am sure there is much knowledge on how to do it on a smaller scale – for home needs but I haven’t been able to find any information on this yet. It may require more manual labour but I am confident it is possible. Our needs are humble – maybe to build another small structure for meditation, enough seeds for eating, making oils … the needs of a small family.
I’ll continue to look for more home-oriented information on this – I promise to share it here when I do find it.
Andreea came across Advantages a local manufacturer of hemp products. There isn’t too much information about them online – but we will be contacting them to see if they know something about building with hemp.
I found this inspiring post on do-it-yourself windows – I found it inspiring because it shows how far you can get on your own with only basic carpentry skills. The price from a professional craftsman was $5500 but in the end they were built in 4 days using $540 worth of materials!
Though I am wondering though if (1) this approach can be scaled up to a larger home and (2) if, with a reasonable investment in time and materials, it is possible to create longer-lasting and energy-efficient windows?
This morning I walked into a cool Yoga room (we usually have in our house one room which is dedicated to Yoga, Meditation, etc.). It’s the coolest of the rooms in the apartment because it’s a corner room and extremely exposed to the elements (and probably not well insulated). This launched us into a conversation about options to optimize the heat in the apartment and that conversation led us into a wider exploration of heating solutions.
Local vs. Network
One quality of a heating solution is whether it is local to the space in which it is installed and operating or whether it effects other spaces in the house. For example:
A local system would be an electric heater that effects primarily the space in which it is activated.
A network system is the central gas heater installed in our rented apartment – it heats up water to a set temperature and that water flows through a network of pipes that lead into radiators ain all the rooms of the apartment. A single mobile wireless thermostat can be placed in any room and it trigger the central heater into operation. If it is placed in a cold room it activates the central heater until the designated temperature is reached – but it’s effect is felt everywhere as other rooms heat up as well (potentially beyond the designated temperature – as is the case with the poorly insulated Yoga room).
Any heating system requires an energy source. These can be gas,electric, fire wood, solar, infrared, geothermal … and there may be others.
The preferred source can be a function of:
Availability – gas pipelines are an established infrastructure in Romanian cities, less so in villages where you have to rely on refillable pressured-gas containers. There are relatively new technologies that make it possible to manufacture gas from animal feces (we hope to find more information on this).
Ecological effects (we don’t know enough about this yet)
To the best of our current knowledge there are three application for heat in a home:
We are not experts on heat and efficiency but common-sense indicates that efficiency is worth noting and can potentially be optimized. Some examples:
When the water heating source is far from the hot water faucet – there is some waster of flowing water until water is heated and reaches the faucet.
When the faucet is opened briefly (for example – rinsing the hands while cooking) and the faucet demands hot water – water doesn’t arrive in time but the heater is activated pointlessly – a pure waste of energy.
Pipes that connect radiators to a central heating system also radiate heat – probably not as effectively as the radiator.
Requirements of an Ideal Heating System
An ideal heating system for us would be a system that:
Can effectively heat any single space in the house (local)
Can effectively heat other spaces in the house (network).
Relies on an available and affordable (ideally – self generated) energy source.
Is multi-functional so that a single heat source can be utilized for other needs. For example, if cooking in the kitchen, that same energy can used to heat the kitchen and optionally other rooms in the house.
Can be targeted effectively depending on the need. For example, if cooking and there is no need to heat other rooms, do not let hot water escape unnecessaritly to other radiators in the house.
An Imaginary(?) Integrated Heating System
This potential system (imaginary is there because we have not yet encountered such a system) is designed for a village house in Romania. So if you live in a different climate with different needs it may not be ideal for you.
It is based on our common-sense understanding of how heating system work and our needs.
It is based on an aspiration to live in a self-sustaining how – which means as independent as possible in everything including its energy sources.
The primary heat source is fire wood. Fire-places are installed in every room which we want to be able to heat individually. Ideally this is an every room – though there can be joint-fire-places that are installed on shared walls.
A small gas-based central heater is used for hot water when only hot water is needed or during summer months when there is no need for environmental heating.
Solar panels are used for an alternative hot water source during sunny days.
All of the rooms (except maybe the living-room?) are equipped with water-based radiators that are hooked into a central house-wide network.
All of the hot-water faucets are connected to a separate (from the central network) one-way (no returning water) hot-water channel.
Each of the fire-places is:
Connected to (installed with?) an adjacent boiler which is connected to the central heating pipe-network.
Connected to the central house network with an open-close control mechanism.
Connected to the hot-water channgel with an open-close control mechanism.
A gas-based central heater is connected to the hot-water channel.
A solar panel water heating system is connected with open-close controls to both the hot-water and central house network.
What this creates is an effective heating system in which:
Any of the fire-places can optionally take the role of a central heating system.
The fire-places can work together for greater power and efficiency when they are used for heating.
Alternative heating sources can be hooked up to complement and support the system.
Such an ideal system is probably prohibitive to install (lots of piping, numerous boilers, etc.). A specific house-design can probably help to whittle the size of the system down by reducing the number of elements. But more importantly – with a good and accessible infrastructure in place it may be possible to gradually expand the system as needed or as if financially possible. It feels like one of those cases where a bit more thinking and design can lead to a better system with very little overhead expenses.
Framing (as I have recently learned) is a term that describes the wooden infrastructure of a house. I’ve started searching around – and this is the first simple and useful post I found on framing – at least for someone like me who knows nothing about it. It’s not much – but a simple illustration, component names and the basic logic of framing are all in this concise post.
