Mud Bubbles

I had to go all the way back to post #1 to find the reference.

I have my own design, of course. It has a general leveling (see the cut-and-fill that Geoships did). But then to mimic historical precedents it has a fire ring in the center, in a sunken conversation pit.

Except this fire ring would be a smokeless fire pit..

The two step pit would have a sump underneath and an air tube that spirals in from the outside. When the fire pit is not in use, it can be a fan-driven earth-tempering air intake.

Any arbitrary soil sample will need amendments, usually clay or sand. A rammed earth floor can be stabilized with ox blood or rice water. Upper floor levels would be shoes off, burnished hard wood.

Oxblood? Ummm that's a programmer's insider joke.

The issue I see with ceramics is that they tend to be brittle and don't like movement. Not a candidate in the west. However depending on definition, bricks are ceramic and if one used a RTV you could get ceramic "bricks" to work well

[freebeard]

It was the practice in Medieval times, when oxen were more common. Can't find a reference.

Technically, it's a geopolymer. The Geoship CEO, Morgan Bierschenk, describes it as similar to bone. It cured at room temperature, in from 45 down to 3 minutes, depending on how hot the mix is.

I emailed this to someone else, and thought I'd post it here.

Building ecovillage of storm-proof homes made of bone-like biomaterial

Kirsten Dirksen does Geoships. There is an interesting progression -- the first half is a good look at the factory and their one built example. Then it flashes two or three minutes of computer graphic walk-throughs and fly-throughs and finishes with an extended visit to their chief designer's glamping setup.

They haven't solved the ingress/egress problem. Here's how to make an octagon house zome (not dome) with flat walls (or not):

Maybe I'm hallucinating, but I can see three things come together

1. Buckminster Fuller's Flys Eye Dome patent
2. the Geoship ceramic dome initiative
3. Artificial Intelligence's penchant for circular windows and compound curved interior walls.

Now, Geoship's current design has three layers, an inner shell, trussed struts, and an outer shell. Fuller's Fly Eye uses compound curve panels. Combine the two and you have two layers, the Fly Eye interior, [an insulative cavity] and flat/curved outer panels.

Fly's Eye Dome
The Fly's Eye Dome was a structure designed in 1965 by R. Buckminster Fuller. Inspired by the eye of a fly, Fuller designed the dome as his idea of the affordable, portable home of the future, with windows and openings in the dome to hold solar panels and systems for water collection, thus allowing the dome to be self sufficient. Before his death in 1983, he hand-built three prototypes of the design:

Buckminster Fuller's buckyballs and domes are not in fact compound curves but a collection of flat surfaces no good for aero, which is why I lose interest here.

As far as buildings go; rectangular shapes are far easier/cheaper to construct, so I/we are at a bit of a loss as to your predilection for them?

I have a predilection for the 60 atom carbon molecule (C60 BuckyBall) because, dissolved in olive oil (C60 OO), it doubled the life/youth-span of lab rats with not a single cancer cell in sight.

Some one with a wind tunnel should do the experiment. The smooth sphere, the icosahedron and 2v and 3v geodesics. One of those will have the lowest Cd (Reynolds number vs scale), and given the dimpled golf ball as an example, I'd suspect the 2v sphere.

As dimensional materials give way to 3D printing, cheap construction will give way to psychologically benign spaces. Boxes make us a little cra-cra.

C60 is but one example of a class of materials, the fullerenes. The real magic happens when 2D molecules are layered at specific angles(*).

Scientists Just Cracked the Code for Twisting and Stacking 2D Materials
Feb 27, 2025The research team demonstrated that by designing specific precursor molecules, they could precisely control the twist angle of the stacked COF layers to form a moiré superlattice. Unlike inorganic 2D materials, where the twist angles are often random and difficult to control, in 2D COFs, the twist angles can be controlled by designing the ...

Mar 4, 2025The stacking and twisting two (or more) layers of two-dimensional (2D) materials results in the emergence of a large-scale moiré pattern which gives rise to novel properties.

Stop scaring away readers from my thread. I'm not that other guy.

edit:
I went looking for references on C70 and other exotic fullerenes, and found this supporting medical uses:
pmc.ncbi.nlm.nih.gov: Biological Effects of C60 Fullerene Revealed with Bacterial Biosensor—Toxic or Rather Antioxidant?

Nanoparticles have been attracting growing interest for both their antioxidant and toxic effects. Their exact action on cells strongly depends on many factors, including experimental conditions, preparation, and solvents used, which have contributed to the confusion regarding their safety and possible health benefits. In order to clarify the biological effects of the most abundant fullerene C60, its impact on the Escherichia coli model has been studied. [blah, blah, blah] The ability of C60 to penetrate through biological membranes, conduct protons, and interact with free radicals is likely responsible for its protective effect detected for E. coli. Thus, fullerene can be considered as a mitochondria-targeted antioxidant, worth further researching as a prospective component of novel medications.

shop.nanografi.com: Types of Fullerenes and their specific uses (C60, C70, Fullerenols)/

Fullerenol

The derivatives of the fullerenes that are soluble in the water are called Fullerenol. These molecules have the ability to remove free radicals. Fullerenols are commonly called as ‘Radical Sponges’, due to their characteristics of removing free radicals. They have great antioxidant properties due to the delocalized double pi-bond in the cages of fullerenes. They are mostly synthesized by the addition of the hydroxyl groups to C60 fullerene. Fullerenols possess a hollow-spherical shape as fullerenes.

Applications of Fullerenols

Fullerenols find the widest application in the field of science and technology. The ability of fullerenols to soluble in water extends its uses in medical applications. They can be transformed into triplet state with the help of ultraviolet or visible light. The transformed material is very reactive and can rapidly react with oxygen or other biomolecules and found its applications and uses in photosensitization. They are excellent antioxidants as well. Their dual nature enables them as cytotoxic materials in the diagnosis of tumors cells and as an immunity agent in normal cells to protect them.

I didn't even get to magic angles. but if you can get one fullerene [nanotube] inside another, define an axis and apply forces -- that might constitute the world's smallest violin servomotor.

And they often make better use of space than, for instance, an A-frame cabin.
