Armor Cloth: “Utility Fog” Without The Need For Nano


About twenty years ago, way back when I was taking my courses in electronic repair, I got interested in MEMs, Micro Electro-Mechanical devices. They were at a very early stage then, barely even out of the lab, but the potential was so enormous that I spent considerable time thinking about ways that they could be used to create unbelievable amounts of change in our daily lives without ever invoking nanotechnology. I really wish I still had all the notes I wrote down, but sadly they got lost over the course of a couple of hard drive crashes and moves.

I’ve already introduced two of the concepts I had contemplated on H+ magazine and here on Acceler8or —I discussed the Camera/Display MEMs in my article on Quantum Dots, and cloth composed of synthetic muscle fibers in my article on “dirty” uses for technology. These are two of the multiple items I collectively called “Active cloths” because they were all basically types of cloth that did something rather than merely set there. “Display cloth” and “Muscle cloth” were the simplest of the four, followed by “Cling cloth” which used static fields like a Gecko’s foot to cling to any surface, and the last and most complex, “Armor Cloth.”

Armor cloth was inspired by several Sci-fi novels that described “spacesuits” that could harden on impact to prevent penetration of blades or projectiles, then return to cloth-like softness. My concept revolved around cubical MEMS, each about a micron on a side, joined to each other by telescoping links — essentially ball joints at the ends of a shaft that could extend about 3 microns or collapse to less than one. This would allow each cube to connect to six other cubes in a network that would allow the entire structure to act like cloth on a human scale. As I planned to make these cubes out of carbon, as well as the shafts connecting them, it seemed reasonable to assume nearly diamond-like strength for any individual unit, and with multiple layers of thickness, an overall toughness likely to withstand impacts sufficient to protect an individual from most forms of combat weaponry short of anti-tank rounds. Under normal circumstances, the “blocks” would use small magnetic fields to repel one another and remain extended, giving the cloth-like effect. However, at the moment of impact, these fields would reverse, causing the “links” to collapse as each cube snapped against their neighbors, creating a “solid”. As I had oriented these blocks to be in a diagonal mesh with the corners pointed outwards, the impact would push the outer layer of blocks against their neighbors in a manner that would divert the force along the cloth rather than through it, allowing the wearer of such cloth to avoid the majority of impact, and prevent damage. While Shear-Thickening Fluids can perform similarly, the advantage to armor cloth is it’s a controllable process. A tiny microprocessor in each cube would be able to control the magnetic fields that either repulse or attract each neighbor, and the strength of those fields. As each cube could identify where it was in the grid, such control would allow a given item composed of armor cloth to be as hard or as flexible as it was programmed to be, even allowing different regions of the same cloth to have different properties.

In other words, this is the “cloth” that Batman is using in his new cloak in the Christian Bale movies. Cloth with a controllable hardness could allow for such things as tables that are strong enough to support an elephant, but that collapse to the hardness of rubber when you trip and crash face first into it. Or a “parachute” that can snap out into a pair of wings like Batman’s cape. I had several hundred pages of concepts that use the properties of armor cloth, from children’s “safe furniture” to full body “Ironman” armor suits designed to protect police and firefighters in dangerous environments and even combat armor for troops. In fact, one of the items I lost is my copy of the letter I sent to the Army’s research division working on combat suits outlining the concept.

The point is that by using armor cloth, you could do some very radical things. Hollow shells of cloth could act like entire pieces of furniture, be it an ottoman or a desk. My wings could be composed entirely of armor cloth, the “arms” programmed to mimic bone, with the membranes as pliable as rubber. Toss in some “muscle cloth” to enable me to control them like wings and, viola, lightweight succubus wings that I can collapse down when not in use.

Now, I’m sure some of you more astute readers will likely realize that “Armor Cloth” is merely a simplified form of “Utility Fog” at the micro scale rather than the nano scale. In other words, it’s a form of Claytronics or Programmable Matter. And I’m sure that many of you are also dismissing this concept as “impossible” or “wishful thinking”. Don’t worry, I’ve been getting that response for nearly 20 years.

Pity is that you are not merely wrong, but in denial. In fact, MIT is already pretty far along in making it a reality. Aside from the telescoping arms connecting each “block”, their “Smart Sand” is virtually identical to the “Armor Cloth” concept. Each block connects to every other block via controlled magnetic fields. Each has a tiny computer able to determine its place in the whole and vary its “magneticness” according to a program. And they can assume any shape that can be broken down into a 3D grid.

Smart Sand. It might be the size of pebbles now, but the concept has been proven, and it’s only a matter of time until it gets smaller. Before very many more years have passed, we might be seeing thousands of products whose “existence” consists of nothing more than a computer file that tells a pile of “Smart Sand” what shape to assume and what properties to have.

So, if I were you, I’d get busy playing Minecraft. Those are going to be some valuable jobs skills in the near future.

Is Stiff Academia Killing Mental Evolution?


One thing I have noticed about the Transhumanist community is that there is a division between the academic crowd and the consciousness expansion crowd. Previous Transhumanist movements have battled on idealistic grounds for the notion of what Transhumanism was really about. Was it the hard scientific outlook with the academic credentials and PowerPoints or was it the consciousness expansion outlook with the mind altering psychedelics and technological revolution? Was the hard academic current stopping the freethinking cyberpunk current from being viewed as Transhuman and was the freethinking cyberpunk current stopping the hard academic current from being taken seriously?

I used to say that the stiff academics were killing mental evolution and I completely sided with the freethinking cyberpunk current. Yet I have recently come to the realization that both currents of Transhumanism are equally important. As freethinking cyberpunks we need hard academics to build a sustainable movement or we will simply come off like a bunch of techno-hippies.

I do, however, wish to address a part of academia that has been upsetting me for a while. I’m talking about the anti-philosophy part which states that philosophy is irrelevant to Transhumanism because we now have technology. The “why have discussions on philosophy when we can build new machines?” people. They are the ones who are killing mental evolution because they dismiss philosophical discourse on the future as all talk and no action.

The last time I checked it appeared that philosophical discourse was required for action to exist in the first place. Would we be able to build new machines if we didn’t philosophize about technology? Why would we want to live in a society of robot builders if we couldn’t even theorize about what we were building? All talk and no action is a definite waste of time but all action and no talk is a cold society devoid of free thought and revolution. I feel that we need a mixture of both. We need the talk and we need the action. We need the techno-hippies who have just discovered LSD and Robert Anton Wilson to throw the raves and we need the MIT graduates to advance genetic research and throw the conferences. We need each and every person in this movement.

Transhumanism has split off into a bunch of different currents and in 2011 this has reached a level so meta-meta-meta that there are at least 30 different groups on Facebook for different currents of Transhumanism. Recently someone in the Singularity Network group asked a question to the effect of “why was I just added to 15 different Transhumanist groups?” Can we blame the hard academic elite or can we blame the petty infighting that every movement inevitably has to deal with? Should we be placing any blame in the first place or should we be embracing the splintering off of so many new movements?

In the end, I believe every MIT graduate was once a freethinking cyberpunk or — at the very least — they embraced these ideals in their youth. I also believe that every freethinking cyberpunk would benefit from a more academic education so they could turn their visions into realities via technology and scientific theory. The only thing killing mental evolution is the idea that ideas are no longer important because … “Hey! Check out those robots over there… and stop talking.”
