cutting glass bottles for the sauna
Still working on the sauna
Some logs are replaced instead with two bottle ends taped together.
Here I share a technique that works well for cutting bottles.
hot tub continued
I’ve taken the hot tub to another level by attempting to incorporate a rocket stove. The idea is for the stove to be at one end, still with the copper coil within heating and circulating the water, and the stove’s chimney to pass beneath the tub to a chimney on the opposite end to maximise heat recovery.
I tried this a couple days ago but it did not work well. I had dug a trench beneath the tub and just laid some iron slates in a U shape the length of the tub and hoped the tub sitting atop of it would somewhat make a closed chimney conduit. It did not work, presumably because it was not airtight at all (despite putting soil around the thing).
Tonight I’ve put a bit more effort into the rocket stove and its super dope. The basic idea is that there is a pipe within a larger drum, and this inner pipe has a conduit that goes through the drum to the outside and serves as both an air intake and fuel intake. The larger drum has a hole cut out (or another hole, seeing as one is already needed to let the pipe conduit through) to which the chimney is connected. I did this mostly with tin snips and made it relatively airtight by filling the gaps with clay. The top of the drum was missing its lid and was pretty rusted out, but I laid a zinc plate on top of it and roughly levelled the rim with clay. The inner pipe was shorter than the drum, coming to about ten centimeters of the zinc plate.
It was nuts how powerful it was. I started off the fire directly in the inner pipe through the top of the drum, which was an advantage of having a removable cover (the fact that the cover did not have such a snug fit did not seem to greatly compromise the draw from the chimney). Once the fire was going well, through only the inner pipe and respective conduit, I added the lid. It choked a little bit but within a half minute the thing was going wild. Eventually it started to come apart however as it had melted the inner pipe conduit.
I guess this was largely a proof of concept. I will make it again tomorrow but with more heavy duty items, like gas tanks, or whatever’s available. It was nice to see that there really doesn’t seem to be any great precision, calculations or measurements, required for this to work. My main concern is that once I add the copper coil between the inner pipe and drum that it might melt but I hope with water circulating through it it will have its heat dissipated.
The hot tub
Building a hot tub seemed like a natural evolution for the garden and I found a 1000 liter drum abandoned in the woods, so naturally the dude abode.
I thought the drum was one that’d been used to hold water, but after angle-grinding it open, I realise it had held oil. Luckily no fumes got ignited in the cutting. I scraped the oil out and washed it down with a bit of acetone, but I think I will sand it down in the end because there’s still a bit of oil hiding in the corners. Also I’ll cover it in something to prevent it from rusting.
The general idea was to make a hot tub that is fire powered in both its heating and water circulation. I was hoping simply passing the water through a coil, itself contained in a bin where the fire is made, would be enough.
It worked relatively well, but was inconsistent in its hot water production and distribution. Also it tended to produce more steam than actual hot water, as if the pressure build-up was not enough to push the hot water through. Furthermore, it seems the water would boil in the tube, but as the pressure would build it would come out both ends, leading to a vacuum which would then take water back in through both ends (this was improved if the designated ‘out’ spout was above the water line). This was not very efficient, although the water temperature was still warm after a few hours of running.
To promote the water flowing in through the bottom end and coming out the top only, I experimented with check valves. I bought two from the shop but they required a lot of pressure just to let anything through. When I’d put one at the top, only steam would come through. When I put one at the bottom, the pull was not enough to open it. So I made one, it was relatively effective as a check valve (hot water was no longer felt coming through the bottom entrance) but it did not improve the water flow as I’d hoped. If I put the hose directly to the bottom of the coil, it all worked very well, but this defeated the purpose of doing this with only fire power.
Next weekend, I will sink the coil into the ground. I’ve read the coil must be below the water tank if it is to exploit the thermosiphon principle. Then, I would like to improve the fire by making the fire pit into a jet stove and then running the chimney underneath the tank to provide further heat. To be continued.
The Sauna
I made some decent progress on the sauna this summer. With the winter setting in, I’ve had to make a hiatus as the mud is not drying quick enough anymore. Even with the last cord I put up a couple weeks ago, it is still not completely dry, and it has started permitting mold to develop on some of the log ends. I have some doubts about this technique. With the wood fiber running through the wall (as the logs are laid on their sides), does this not promote the transfer of heat from the inside to the outside? We will see.
Otherwise I will take advantage of the season to start building the pyramid roof. I’ve come to realise the budget wood I bought is of terrible quality and not suitable as rafters. So I will have to redo the pyramid’s floor if it is to hold anyone. Then I will build the roof frame and tile it. I’ve also got to cut about 400 glass bottles.
In the meantime I’ve been working on a hot tub. A post on this will follow shortly.

Santé et Maladie
La thérapie par les plantes se trouvent comme une des plus anciennes médecine utilisé pour soigner. Bien qu’elle fut attaquée a plusieurs recours lors de sa longue histoire, elle persiste néanmoins, et reste la première source de produits médicinaux globalement. La plante médicinale, ancré à un seul lieu, développe des capacités extraordinaire afin de s’adapter aux evolutions climatiques qui l’entoure, les mêmes evolutions climatique qui mènent à la maladie chez l’humain aussi si elles sont pas correctement gérées. Ces adaptations se font de manière aussi rapide que leur vitesse de reproduction et se manifestent en tant que variations de molécules hyper adapté aux conditions connues.
La maladie se développe quand le corps se trouve incapable de s’adapter a l’environment immédiat qui l’entoure. La santé n’est pas un statut fixe, qui une fois atteint est stable et ne peut être renverser que par une attaque extérieure; la santé est donc un orbit dynamique qui s’effond si elle n’est plus capable danser avec son environment, comme un vélo qui qui tombe si il n’avance pas. Comme le vélo, la santé chute si elle ne continue pas a s’adapter et doit subir bien des lancements de pierre qui la garde bien veillante. Pour soigner, il faut donc bien sur demandé qu’on arrête de jeter des pierres, mais surtout, il faut continuer a pédaler. Une grande priorité de la phytothérapie est donc la restauration de l’état sain, en soulageant les symptômes immédiatement gênant et simultanément par l’encouragement des processus sains dans le corps. Plus profondément, la phytothérapie cherche a trouver les véritables causes de la baisse de santé, qu’elle soit physique ou mentale, afin de l’addresser comme il le faut.
