5. 9. 2007: Temperature Range
Sunset of 4th September 2007
Today 8°C in the morning around 8:00, and later at 14:00 28°C inside the yurt with little sunshine - now it really makes a difference whether the sun reaches the yurt early or late, and in my case the sun reaches the yurt around 10:20, independent of winter or summer as the forest casting the shadow just runs along the sun path of winter to summer.
I fire the stove only at night, from 20:00 for 1-2 hours only - in the morning I put on some more cloth at 8°C til the sun reaches the yurt and heats up the interior by 20°C then.
It would make sense to put up the thermal insulation to keep more warmth through the night.
Compost as Heat Source
I also had a talk with the farmer a few days ago about the compost he takes from a waste deposit facility, and he piles the compost in lanes for a couple of weeks, those create heat of 70-80°C. After two weeks or so the compost drops its temperature.
So I tried it myself, approached the mildly odor giving pile of compost, and on the surface the temperature is a bit below my body temperature, the compost is surprising very wet or moist and slippery. Then I reached into the pile and at 10cm depth it goes well above 40°C, maybe 50°C as I can't keep my hand there without burning the tips of my fingers. It's incredible to realize it's so hot that you can burn yourself, and this kind of heat without a fire or electricity, but an organic decomposting process.
Heat from the compost 2007/09/06 05:47
Touching the compost (apprx. 25°C surface temperature, at 7°C air temperature) 2007/09/06 05:49
Reaching into the compost (apprx. 45-50°C at least, risk of burning my hand) 2007/09/06 05:50
A few projects have tried to extract this heat with copper pipes - yet, the two weeks lasting heat requires then access to the compost and add new green waste and mix with the existing to keep the composting process on-going.
The next days a temperature fall is expected, down to 7°C at night and I thought to attach the stove pipe so I can fire the stove again. It's not really fall yet, and I still have the "summer setup", means, no thermal insulation yet.
Tonight I fired the stove briefly, and it was nice to have steady 20-22°C in the yurt, outside the temperature dropping to apprx. 13°C at 21:30.
Also the negotiated one year to stay at the current place is approaching its end, and this means either renegotiate or find another place, let's see.
30. 8. 2007: Harvesting Bluebyrd Plums
Making plum sauce and jam ... (1)
The farmer, on which land I have my yurt, owns a few bluebyrd plum trees, and the plums now are ripe, and sweet.
It's incredible to see a tree maybe having 80-100kg of plums I would guess, and what we like of the plum is actually only the sweet flesh, but the core, the seed carries the ability to become a tree again, and this we don't eat but "throw" away as maybe intented by nature in order to spread the seeds.
So, I harvested apprx. 8kg plums myself, way too much to make jam from, but I also can't store them without processing them as they ripe further and then rod then.
I will prepare them by remove the core/seed/stone/pit and cook and make unsweetened sauce and fill up in glasses. Finally I made half as jam and half as sauce without additional sweetener and thickener, some I blended even to make it smoother. I used a lot of water (8l) to sterilize all glases and keep everything clean - but it's worth the effort.
These are the little things which come along living in a temporary habitat, and close to nature - you are harvesting what nature provides, such as cherries, plums, and soon apples, and when it's season they come in abundance, in large quantities and require preparation to store them, e.g. for a year.
Watching Neolithics of Pfyn in a row, and considering more food from the nature close by leads to build a garden, and this of course involves a longer commitment to stay at a place, which I'm pondering on now.
The last days I also noticed the first dry leafs falling from the trees, and fog in the morning - fall is approaching.
29. 8. 2007: Neolithics of Pfyn
I took the time the last days to watch all videos (10-15 mins per daily video blog) and 3 or 4 weekly summaries (25 mins each) of "Pfahlbauer of Pfyn" (Neolithics of Pfyn) and I must say the "living-science" project of swiss TV channel SF1 worked well.
The slow pace of the life, and closeness to nature became appearant and was well captured in the coverage. The print media mocked the experiment as boring, slow and without any uniqueness - but I can't subscribe this, I rather find it odd that people cannot appreciate the different pace of living in such a setting, maybe even unable to relate and understand themselves.
Anyway, it was also from the ratings very successful, 50% market share here in Switzerland which is exceptional well, especially given it wasn't made with any silly sensationalism which otherwise seems predominant in TV productions. I personally don't watch TV anymore, not even live-streamed.
Today I was visited by a young radio producer, we did a short interview of 40-50min length, which will be broadcast on a local non-commercial swiss radio KanalK.ch (multi-language radio, but predominatly in german) tomorrow - once it was broadcast I will likely reference it here as well.
The feature won't include any news which aren't already available here, in particular in this yurt diary.
Update: 2007/10/10: it took them forever to send me a copy, so finally:
FreiTalk: Thema 'Austeiger' (2007/08/24), 60mins (spoken in swiss german)
If I get some spare time I may transcribe it. The feature turned out surprisingly nice, and kind of hilareous to listen myself and the jokes I made, silly.
I also just realized that SF1: Pfahlbauer von Pfyn as ended by 20th August; a swiss-german reality documentary of two families living in a bronze age setup, one participant, Joerg Maeder, I met by chance who participated with this project a few weeks ago.
The episodes have been very successful on swiss german TV, but since I don't watch TV anymore (not even live-streamed online) I don't how how the entire project unfolded - there are daily 10-15 mins summaries available, but with my setup I haven't been able to watch them yet - I will download them and convert in order to watch.
I will later maybe cover some of this project here as well- especially when I've got chance to talk to Joerg direct.
19. 8. 2007: Mild Days & Attached Room
Evening of 19th August, 2007
The last weeks have been mild, not too hot, a bit rain - 17°C (morning) to 34°C (afternoon) inside the yurt.
The attached room does well, no strong wind or storm yet tested it, but heavy rain I had and the room was steady and the overall setup leakfree.
I also captured a few mice again, with the alive-trap I had - and dislocated them in the nearby forest.
9. 8. 2007: 2-3 Days Rain: Some Floods & Drinking Water
Apprx. 24-36 hours intense rain over a period of 2-3 days created some floods here in Switzerland (e.g. up to 100l per day per m2, which is apprx. 75% of total rainfall for month August in average), various rivers run high and a few areas are evacuated, or are not reachable anymore on the ground, and have no electricity anymore, not really dramatic but significant to see it takes just a few days of rain to create this kind of effect.
Southern Germany and northern Italy are alike affected.
At the place I am the gravel-based street was partially washed out, and requires reconstruction - near the yurt water comes out of the ground, as I'm on a slope, but the gravel-based ground where the palettes lie on remains steady.
My newly attached room did fine, at one part I had a dent where water collected (maybe 15l), which I use now as drinking water - as due the heavy rain the water I get from the well contains surface water too, not sufficient filtered through the ground - so I prefere the rain water.
The rain water itself should be very sterile as it has been evaporated and now are clouds (removed all remaining particles), the only contamination is due the air pollution, but given I collected rain water of 2nd day (flushed the early collected water from the first day of rain) should minimalize the pollution based contamination.
With the rain it also cooled off, from 28°C temperatures down to 12°C now, and covered sky - inside the yurt now 16°C around noon.
4. 8. 2007: Attached Room
In order to create some additional space I thought to use the lattice wall of my 4m yurt and its door in order to create an attach room:
After Sunset of 30th July 2007
I used the lattice wall entire as one piece, didn't want to break it up - so I used it also along the existing outer wall of the yurt - it turned up a bit clumpsy thereby - if I had it cut apart it would not go up at the upper end.
Anyway. It's a very temporary setup lasting a couple of weeks. The floor I made with one-way palettes with some covers.
With some PE canvas I covered the final attached room, I had to keep it very narrow as one longer PE cover I had left was only 1.8m wide.
Now I move some stuff I have in the barn nearby back to the yurt in this attached room.
The last weeks have been mild, a few days with lot of rain again, but it cleared up again.
13. 7. 2007: Summer Back & Bamboo Treatment
Evening of 13th July 2007
After days and weeks of rain and temperatures from 9°C to 17°C, it's again back to summer, with 26°C and 34°C inside.
For the first time since I brightened the roof and wall bamboo, I had one wall bamboo crack again due the heat. Until now no additional roof bamboo has cracked which I painted more carefully than the lattice wall, harder to paint due all the spaces within the lattice grid (rather brighten the lattice lath before binding them to a wall). I may prematurely conclude already, the brightening of the bamboo minimizes the risk of the bamboo to crack, contrary to what I first was told by the whole sale garden company. The older the bamboo, the greater the risk of splitting as the bamboo get drier and thereby stiffer and less flexible to react to temperature changes like expansion and compaction, the oposite as I was told that remaining humidity within the bamboo was the reason for cracks - I don't think so now anymore.
Evening of July 14, 2007
Let's see the next days, we expect highest temperatures of the year, with 30°C - 35°C - quite a contrast to a few days ago.
I also test a piece of fleece, made of PE fabric I guess, quite robust, aprx. 2-3mm thick, it's used by the farmer for covering compost he processes (formerly "green" waste), I thought to see if I could use it as thermal insulation or wall cover. It soaks itself with water quickly, but drains it quickly too, and dries even so fast. It doesn't rot at all and catches little moss.
10. 7. 2007: Cooler Weather & Rain Again
World Sunlight Map 11th July 2007
9°C outside in the morning - the sun comes through, and inside the yurt quickly 21°C.
The PE cover on the roof is 100% waterproof, but on the side where the wall cover goes over the bit extended floor it has a few small holes to stress and brittle PE where it leaks a few drops on the floor, but neglectable as with little warmth it evaporates quickly again.
The door frame bottom I covered additionally with a piece of PE also does much better, much lesser water entry at the door as before.
Having an extending cover for the door entry for rainy regions is highly recommended, and I may even extend mine further for the fall - this way to protect the wodden door frame further (I used water protecting finish, yet it didn't last much longer than 4-5 months).
The rain also made the ground around the yurt soaked, and I'm glad the place I put up the yurt had gravel already for quite some time which made it more solid, additionally to the gravel I put on - otherwise I would think the floor remaining as stable as it is now.
The last weeks, before it began to rain, I harvested cherries from the farmer's trees, and made jam, the same with peaches I bought, they ripe faster in the warm yurt and I didn't want them put in the plastic box in the water well, where I otherwise store food which needs to be cool.
In general I cook vegetables entirely, one part to eat as meal direct, another parts I blend and mix with olive oil as salty paste and put (still hot) it into empty jam jars, to use later as cooking additives or on bread. Maybe it's getting time to collect my cooking recipes too.
The last 3-4 days I catched 4 mice with a living mouse trap, it seems the rain of the last days and week made them seek drier place, my yurt - yet, their urine and feces make co-living the same space inacceptable, sorry mice!
So I dislocated each of them in the nearby forest.
