]. I'm wondering if you are able to use the woodchip infill as an insulative layer between two cob mortar 'walls' as is done with concrete, or are your cobbing mortar layers continuous in the length of the piece of cordwood? I hope I described it properly. I will elaborate: With the place that I helped with, once it was solid, we had basically two concrete walls (six inch patties of mortar near the ends of each 24 inch length of wood, which joined previous layers of concrete patties), with wood chip insulation (a little less than 1.5 feet) between these concrete walls that formed from the joined patties, laying on the centers of the wood rounds (which projected slightly out of the concrete). The main reason that I'm asking is that if you have the chip insulation, and 24 inch walls, in addition to proper windows and door units for your climate, then you are likely to not need nearly the heating that you describe. I'm not sure, but that's my guess.

I have no experience with that though.
In fact, because our 8" RMH is tied to the earth down here, even a lot of the heating produced ends up running straight down into the soil beneath us. That's a positive in that it does keep the frost from penetrating into our "indoor" space, but we do lose a lot of heat. The heater mass is almost perpetually damp on the bottom inch or so as well, even though we have some 10ft of space between it and the "outside", AND we put down a layer of plastic membrane under the majority of the bench before even building it.
What works, what doesn't, what makes the most impact for smallest input and what is basically a waste of time/energy/money. Each little thing we do "down here" gauges whether it's worthwhile to do on a larger scale "up there". And trust me, some days I have to forcibly remind myself of this fact!

I don't think that that is accurate. Poplars are not nitrogen fixers, from what I know. They do provide a lot of biomass (leaves/deadfall), which have the potential to aid in nitrogen sequestering (through fungi), but they do not fix nitrogen leguminously from what I understand. Further, poplars have incredibly wide seeking root systems that will enter other systems (up to 200 feet away from what i'm told) to gain nutrients or to spread their clonal colonies (while not fixing nitrogen, they may actually be taking it from other desired plants!).quaking aspen saplings (what the locals call popples) since they're N-fixers,

Second or third growth trees have grown much faster in general and are softer and rot rather quickly. I hope your treatments and "dry pad" help with that. I might try using them above grade (on stone pads, maybe with the bottom of the post 1" below finished floor if you are concerned about future inspectors' classification as "timber-framed on foundation"). I would be very pessimistic about hemlock exposed in exterior walls and sunk in the ground, if you plan any of those.
I have plenty of experience with small maple poles, and yes, flexible when green, getting brittle and splitty after some years of outdoorish use.
Locust is so strong that even a 6" post would have structural value, though you might want more of them for assurance. I have also found black cherry to be quite rot-resistant, if you have any of that that is big enough to have real heartwood. (Black cherry is also gorgeous when planed and aged.)
About mass inside the structure, as long as it is not exposed to weather or ground conduction, it will not in any way take more power to heat. It will take more to get up to temperature, but will hold the heat longer and give a more stable environment. For long periods of constant cold weather, the more mass the better. If you are planning a thick clay pad isolated from ground moisture and conduction, you may well run the ducts through that and give yourself warm floors.
The logging industry literally wiped them out in my area - no oaks, no black cherry, no walnut, no chestnut (though that could be blamed partially on the blight as well). The neighbor's father tells of a time not that long ago when oaks were the predominant species in this area, but today it's mostly sugar maple, birch, beech and balsam fir. Even the pines and hemlocks are petering out with the frequency of cutting and poor genetics left behind to seed.
Another option might be to use one of the more caustic, nasty, toxic gack preservers, but I'd like to avoid that if possible (both for sanity and $$ reasons)
Within the first few months, I had to completely scrap the idea of building a standard "log cabin" due to the sheer number of trees I'd need to build something large enough to call a "home". Moving to roundwood timber framing and cordwood/cobwood was a choice driven by the lack of good quality boles on the property and the relatively small diameter of what we do have.

I can see how the through log is likely there to stabilize between the two cob walls, particularly on your narrower walls. I'm not sure I understand the full pattern in your second typed sketch. Mostly the ==***== log insulation log units. Is there no mortar on these logs? Or are they two short rounds in each cob wall, with a full space of insulation between them? The rest seems pretty logical.

The total run is around 40ft, shaped like \__/ with the opening to the south to capture sun/heat. Later this spring, we'll be planting out butternut hills and some cucumbers in this "courtyard" as it should work well for a heat trap.
The bin farthest from the camera is an assortment of peppers, both sweet and hot, followed by the big tomato sandwich toms (brandywine, cherokee purple and debaro), followed by the early cherry tomato (which didn't sprout at all) and the oregon spring (which damped off badly but replanted and they came in nice). Along the side of the bins, the plastic tray closest is seeded with common thyme, the bit of egg crate was supposed to be basil, the milk jug bottoms are our rhubarbs, on their second year (not doing so hot yet, but hey...they're still alive!), the toilet paper rolls are comfrey that actually sprouted this time, plus some store bought scallions/green onion growing out their roots for planting.

Well, not exactly in these shots...they've been going out off and on since late winter, but now that there's no cold wet white sh*t on the ground and there's things to chase, like cabbage moths and baby grasshoppers, they're starting to really love it.

What is the average humidity there? Here in western WA it's around 75% annually. It's damp enough through the year that power washing your siding is a good thing to do and I live a good 35 miles away from Puget Sound.
LOVE the snow pics!
It was getting so dry, we didn't even get frost on a few nights that dropped into the 20s!

As noted in the first post, nominally, it could harvest 700 gallons per inch of rain. In reality, that was probably more like 500 gallons with splash, water missing the barrels during heavier downpours and puddling followed by evaporation. Still, I'd estimate we harvested at least 1,500 gallons between early august and middle october - a life saver for us and the ducks on such a dry year. We even were able to stock up on water going into the winter freeze this year, putting away around 300 gallons total before the first snows hit and took the structure down.
Once you've thrown in some scrap rope, there's nothing that can't be done.
As it stands, even on partly cloudy days around this time of year, we're getting a good 30-40amps of charge off the 3 panels - that's more than half of what we use in a day. We're having to rely on the generator less and less, and that means less trips to buy gas, less ugly, noisy, stinky generator time, and less wear and tear. We've needed to run the generator once and sometimes twice a week, burning about a gallon each time, since middle december. This is down from every other day, burning up to 1.5 gallons each time, just two winters ago.
Rather than continuing the pines up along the western shore, the area to the north and west of the pond will be contoured a bit and planted with primarily juneberry (likely Amelanchier alnifolia), possibly mixed with some sand cherry (should the soil dry out enough) along with a few eastern redbud and manchurian apricot. Until the soils are ready, we'll be putting in more annual garden beds through that area for the next couple years.
You'll note in the video that I talked about some red maple in the pine forest suffering heart rot - these are all coming out of this area as I really would rather focus on the sugar maples where I can.
In fact, I'd like to set up a relationship with a local restaurant if possible, but that's a whole other story. With the layers laying an egg a day, plus all these muscovy laying every day or two through the first half of summer, we're liable to be drowning in eggs if we don't find a market.
Egghead and Surrogate are sitting, plus 4 of the ducklings from last year on 3 other nests (yes, 2 ducks in one nest...again). We've kept a total of 10 muscovy girls - 4 from the original raft and 6 of their daughters from last year. To avoid any inbreeding, all muscovy drakes were culled by the beginning of March and I ordered 18 fertile muscovy eggs from a random farm on ebay to (hopefully) introduce new genetics through 3 drakes. These are in two of the nests. The other 60 some-odd eggs, with more to come, are golden layer offspring and sterile moullards from the layer drakes servicing the muscovy girls. Next year, the layer drakes will be replaced with new blood as well to avoid issues with the mallard genetic lines.
So, about a year later, I'll get some pictures from last year up, maybe a few winter scenes, and finally (maybe) the pics I just took this evening. Lots more gardens, lots of ducklings running around last year, and so on...otherwise, not too much progress on the overall picture really. It's been difficult to get things rolling on things between finances (which are always lacking it seems, no matter what) and delays on excavator work last year.
