There is, however, a mangrove honey produced in Kenya that reportedly is useful in treating smallpox. :unamused:

Perhaps the bees can be trained to use old termite mounds as a new hive.

I reckon just one mile-high bee hive could generate enough mangrove honey to treat all the smallpox cases in the world. :wink:

If only someone could train the termites to build their mounds in the shape of submarines …

The “termite analogy” is actually the most simple way i can think of to explain the advanced composite shell dot printing concept … but even so - people keep missing the points. Can we work on simplyfy it further or is it better to just stop communication under the hypothesis that we do not have the correct auditorium here…or we are crappy teachers who fail to bring it over - who knows…

Just let´s hope some of the 660 silent users of this forum got it and move on...

(Matias Volco) #30

It is a very good analogy - along with your latest video releases it gave the impression that you had entirely spilled the beans (technologically speaking).
I will show the scale and proportion which is what folks might have some difficulty with

Maybe bone structure is a better and easier to understand analogy ?

But it is probably more complicated to bring over the work of osteoblasts than the work of termites…

A osteoblast is a faceless cell that segregates bone structure… harder to relate with than a termite who is at least a critter people can see and watch…

The interresting point in osteoblasts is that they keep bones growing according to the stress they are experimenting. If the bone is in overload some of those microstructures start breaking - osteoblasts detect that “microfractures” , repair them and double them up. So you get a bone structure that is reforced EXACTLY where load bearing capacity is needed.

I assume at Zaha Hadid Architects finite element computer programs are used to solve such complex structures. - Interrestingly osteoblasts get similar results just by detecting stress repair and double up.

(Matias Volco) #33

Humans do that too but it is apparent only in the microscopic and very large, satellite-picture scales. This gap is where our communication department obviously needs to focus.

i.e. in a large human colony, when a thoroughfare is overloaded (with traffic, not weight) it breaks and doubles up.


When we notice that is how erosion also works in non living things, we understand the “universality” of this evolutionary strategy.


Yes, computer power can help us simulate this cycles - but it’s not necessary to understand them. Zaha made us draw curved lines to detect where “fractures” should be with the same natural ease we can detect 90 degree angles

It is of essence for a seastead concept that the possibility of growth, of adaption to change, is hardwired into the concept…


So, please explain how an unreinforced, wattle and daub structure is:
A) waterproof
B) pressure resistant to over 160 atmospheres
C) modular extension

In the context of forming big continuous structures in freeforming that can be expanded without modules and connectors - what is happening in the universe of projected concrete is worth to be mentioned.

Here you have the seperation of fiber component (rebar) and cement/aggregate component …

The methods that create the underwater tunnels and swimming pools of today lead naturally to the methods that create the floating cities of New-VENICE and New-Atlantis of tomorrow.
In the Oceanic Business Alliance we believe in the "natural evolution" of things. What will be here and big tomorrow is already under development in some special niches today...
Those of the audience who have followed my discourse over the years know that among our technology pilot projects are fully functional submarines built from advanced cement composites. So it is reasonable to accept the working theory that building a "floating island" is a relative simple task for our group.

Once you leave the universe of simple cast concrete engineering - shapes and possibilities become literally limitless…

The whole idea that making things boxy and angular in modules that are bolted together - is probably just a lack of imagination and a lack of knowledge what is “out there and working fine already” …

The legacy of Zaha Hadid is in inviting us to “think beyond the box”… and coded engineering.



You have yet to answer 3 simple questions, regarding your described method.

please provide answers to the relevant inquiry…

One cubic meter of fresh water weighs 1000KG. A kilogram is roughly 2.2 lbs. So a cubic meter of water weighs roughly 2200 lbs or just over one ton. I don’t think your cube will weigh quite that much so yes, it will float.

If it weighs less than one cubic meter of water … then it will float. Right?

But buoyancy must be measured by the weight of the fluid displaced. A rock is buoyant in melted lead, but not in water. Same rock, different fluid.

In the context of “projected concrete and advanced composites” you should also have a look on what was published by @Elwar back in 2015 in this thread especially the last video shows how a “surface film” can “vastly change” the overall property of a piece.

You can take a surface film as a "fiber component" introduced at the end of the build...
The fiber component in a composite does not have to be mixed in - it can be performed in layers and independent of the cement and the filler components.

watch a man “walk on water” with the help of a sprayed polyurea film…

• what can you do with a polyurea sheet sprayed on the watersurface for a mile or so…in a contiuous process by a floating fabrication site ? (check how Solitaire does pipe laying to get the picture of a floating factory building oceanic infrastructure…)

• When combining 2 materials right you can make a watertank out of a cardbox … it is not about the specifics of materials - it is about the surprising properties that emerge if you COMBINE them.

• In advanced composite materials it is not about the material per se it is about the Builder getting it right.

• Building in advanced composite materials is rather an artform that requires a deep understanding and know how from the builders … so building logistics is one of the reasons why we don´t see it implemented frequently on large scale already. - The other reason is “pre-coded construction ambients” that exclude new things by default as non-code-conform.

It is the code free ambient of seasteads that allow “free choice of options” that will liberate the power of those technologies on larger scale.

Another surprising composite tech…unite modules with a film component and “unbrittle a brick”…

This is ONE method how you avoid CONNECTORS…

(Larry G) #58

Polyurea is great. It’s not used for connections. And it doesn’t keep the underlying brick from shattering. It superficially holds it in place, and it does make it a little tougher against random small impacts. But once it exceeds its impact tolerance, it is no longer structurally sound. You couldn’t put weight or shear stress to it.

I do think there is something to the idea of laminate layers- for substances that self-adhere after cure.

What happens when someone steps onto a plastic swimming pool cover?

(Wilfried Ellmer) #59

Consider it rather the consistance of a 7 cm sheet of ice - a man can step on it… and don´t get me wrong the above examples are not my “suggestion how to build a seastead” they are examples for how in composite materials new properties emerge by combining 2 (or more materials) - and how these new properties can be VERY DIFFERENT from the properties one of the materials has on its own without combination.

Just think in carbon fiber pieces - their mechanical properties are certainly not that of “coal”…

It is not about poly-urea or carbon fiber - or basalt - or geopolymer - to choose above everything else - it is not a "either or" it is a "all together" - there are literally hundreds of materials that can be combined to composite materials with surprising properties - just look at the floating rock in the video above.

(Wilfried Ellmer) #71

Finite Element programs allow to get a clear picture where in a complicated truss structure the stress is biggest (red part) and builing in composite material allows to enforce on the exactly right spot with the right component ( compression, tension, or torsion stresses ) increasing the fiber or the cement component on structural demand.

This is again an example how new technologies work together to create something new - a new style of building for new ambients.

We are learning to apply the tricks of the termites and the osteoblasts. That makes building logistically more complicated and demands a better understanding from the architect and the builder.
