A Utah-based startup company called Chamtech Operations is claiming that its Spray On Antenna Kit can turn any surface into a high-powered antenna.
As explained by Anthony Sutera in the video below of his presentation at Google's Solve for X event, “Our material uses thousands of nano-capacitors that we can spray paint on in the right pattern. All of these little capacitors charge and discharge extremely quickly in real time and they don't create any heat. When we hook up our material to a radio, the signal hops from capacitor to capacitor very quickly, finds its happy spot, and launches into space.”
Imagine painting wireless antennas on walls. Instead of planting them as fake trees or simply uncamouflaged, phone companies will blend their unsightly cell towers into the landscape. They could even commission artists like Haas & Hahn to turn the city as though fully draped with Joseph's Amazing Technicolor Dreamcoat.
Alternatively, they could enlist children from local elementary schools to reconfigure the city's electromagnetic infrascape in exchange for very plump donations. Is that mural on that once seamy but now chromatically resplendent underpass depicting the neighborhood's tempestuous history and encouraging future, their parents will ask. Why yes, they'll answer back, and you can also bounce phone calls off of it.
Elsewhere, graffiti artists will independently fill in the dead zones. Or maybe not to patch up the network, but rather as part of a collaboration with sound artists to create a pop-up pirate radio station to broadcast an improvisational audio documentary of the local area. During times of protest, they could be used to burst through whatever electromagnetic kettling the security forces might be using to prevent the crowds from organizing and reaching critical mass. If there's no graffiti antenna nearby, just whip out a Spray On Antenna Kit to reclaim the public spectrum.
In any case, I'd like those “nut jobs” at DEMILIT given some of the stuff and see how they might use it in one of their sonic tours of military landscapes. Will they spray it on crumbling bunkers and derelict silos, thus repurposing them into antennas to transmit in real-time the acoustic ecology of war?
What might avant-gardeners, who presumably already know how to harness energy from trees, do with the stuff if they find out that you can also apply them to trees and turn them into arboreal arrays?

Feel Me is a project by Marco Triverio that explores the gap between synchronous and asynchronous communication using our mobile device in attempt to “connect differently” and enrich digital communications. Whereas we draw lines between phone conversations and sms messages, Feel Me looks for space in between that would allow you to be intimate in realtime, non-verbally using touch.
Based on the finding for which communications with a special person are not about content going back and forth but rather about perceiving the presence of the other person on the other side, Feel Me opens a real-time interactive channel.
Feel Me first appears to be a text messaging application. When two people are both looking at the conversation they are having, touches on the screen of one side are shown on the other side as small dots. Touching the same spot triggers a small reaction, such as a vibration or a sound, acknowledging that both parts are there at the same time. Feel Me creates a playful link with the person on the other side, opening a channel for a non-verbal and interactive connection.
“Feel Me” was awarded honors at CIID. Marco is currently working as an interaction designer at IDEO.

A new way to harvest footfall energy could someday let shoes generate enough power to keep cell phones and laptops topped up.
University of Wisconsin-Madison researchers have come up with a microfluidics technique that scavenges considerably more energy from human footfalls and converts it into electric power. Previous attempts to make energy-harvesting shoes have yielded less than a watt of power, but the new approach could lead to a shoe-mounted generator that produces up to 10 watts, says Tom Krupenkin, a mechanical engineering professor who led the work.
For a mob to be smart it needs to be able to network. The fascinating work of Dr. Suzanne Simard says that trees do just that: use networks to communicate. Brian Lamb introduces what is being learned from mycorrhizal networks in a post on his blog Abject.
This is what our state lines might look like if we drew them based on who actually talks with each other, at least according to cell phone data gathered by MIT. These are the geographic clusters of who texts with whom within an area, from the MIT Senseable City Lab's Connected States of America mapping project.
If volume of communication determined state lines, New York City would break ranks with the state that shares its name and join up with oft-maligned New Jersey. Mississippi and Alabama would merge, so would most of New England. Wisconsin would split in two to join Illinois and Minnesota.
But one can also look at how a given regions talk with other regions, and how close those ties are, distance factored in. The map below is of Los Angeles' connections to the rest of the country. Red areas are those with the most connections to L.A. according to cell phone conversations.
The Connected States of America project's interactive maps and visualizations show us how different parts of the country interact, and raise the question, what is a community? There was a simple answer 60 years ago when geography determined who you talked with, bonded with, and spent your life with. Now that families are scattered across the country for college, jobs, or wanderlust, and companies set up bi-coastal offices without a second thought, that's no longer true. Should we care that the people we're most connected with aren't necessarily nearby?

A recent paper published in the Physical Review has some astonishing suggestions for the geographic future of financial markets. Its authors, Alexander Wissner-Grossl and Cameron Freer, discuss the spatial implications of speed-of-light trading. Trades now occur so rapidly, they explain, and in such fantastic quantity, that the speed of light itself presents limits to the efficiency of global computerized trading networks.
These limits are described as "light propagation delays."
[Image: Global map of "optimal intermediate locations between trading centers," based on the earth's geometry and the speed of light, by Alexander Wissner-Grossl and Cameron Freer].
It is thus in traders' direct financial interest, they suggest, to install themselves at specific points on the Earth's surface—a kind of light-speed financial acupuncture—to take advantage both of the planet's geometry and of the networks along which trades are ordered and filled. They conclude that "the construction of relativistic statistical arbitrage trading nodes across the Earth’s surface" is thus economically justified, if not required.
Amazingly, their analysis—seen in the map, above—suggests that many of these financially strategic points are actually out in the middle of nowhere: hundreds of miles offshore in the Indian Ocean, for instance, on the shores of Antarctica, and scattered throughout the South Pacific (though, of course, most of Europe, Japan, and the U.S. Bos-Wash corridor also make the cut).
These nodes exist in what the authors refer to as "the past light cones" of distant trading centers—thus the paper's multiple references to relativity. Astonishingly, this thus seems to elide financial trading networks with the laws of physics, implying the eventual emergence of what we might call quantum financial products. Quantum derivatives! (This also seems to push us ever closer to the artificially intelligent financial instruments described in Charles Stross's novel Accelerando). Erwin Schrödinger meets the Dow.
It's financial science fiction: when the dollar value of a given product depends on its position in a planet's light-cone.
[Image: Diagrammatic explanation of a "light cone," courtesy of Wikipedia].
These points scattered along the earth's surface are described as "optimal intermediate locations between trading centers," each site "maximiz[ing] profit potential in a locally auditable manner."
Wissner-Grossl and Freer then suggest that trading centers themselves could be moved to these nodal points: "we show that if such intermediate coordination nodes are themselves promoted to trading centers that can utilize local information, a novel econophysical effect arises wherein the propagation of security pricing information through a chain of such nodes is effectively slowed or stopped." An econophysical effect.
In the end, then, they more or less explicitly argue for the economic viability of building artificial islands and inhabitable seasteads—i.e. the "construction of relativistic statistical arbitrage trading nodes"—out in the middle of the ocean somewhere as a way to profit from speed-of-light trades. Imagine, for a moment, the New York Stock Exchange moving out into the mid-Atlantic, somewhere near the Azores, onto a series of New Babylon-like platforms, run not by human traders but by Watson-esque artificially intelligent supercomputers housed in waterproof tombs, all calculating money at the speed of light.
"In summary," the authors write, "we have demonstrated that light propagation delays present new opportunities for statistical arbitrage at the planetary scale, and have calculated a representative map of locations from which to coordinate such relativistic statistical arbitrage among the world’s major securities exchanges. We furthermore have shown that for chains of trading centers along geodesics, the propagation of tradable information is effectively slowed or stopped by such arbitrage."
Historically, technologies for transportation and communication have resulted in the consolidation of financial markets. For example, in the nineteenth century, more than 200 stock exchanges were formed in the United States, but most were eliminated as the telegraph spread. The growth of electronic markets has led to further consolidation in recent years. Although there are advantages to centralization for many types of transactions, we have described a type of arbitrage that is just beginning to become relevant, and for which the trend is, surprisingly, in the direction of decentralization. In fact, our calculations suggest that this type of arbitrage may already be technologically feasible for the most distant pairs of exchanges, and may soon be feasible at the fastest relevant time scales for closer pairs.
Our results are both scientifically relevant because they identify an econophysical mechanism by which the propagation of tradable information can be slowed or stopped, and technologically significant, because they motivate the construction of relativistic statistical arbitrage trading nodes across the Earth’s surface.
The photo above is, according to the BBC, an extremely rare photo of Barack Obama inside his top secret tent. The tent is an example of a mobile secure area also known as a Sensitive Compartmented Information Facility, or SCIF, "designed to allow officials to have top secret discussions on the move." In fact, the BBC reports, "they are one of the safest places in the world to have a conversation."
This particular SCIF has been set up in the middle of a hotel room in Brazil—you can see the carpet pattern on the floor. Obama was on a pre-arranged trip to Brazil when airstrikes in Libya began on Saturday, and needed a secure facility from which to talk to his Secretaries of State and Defense, as well as fellow coalition leaders.
While the tent material looks like fairly standard blue tarpaulin, it is actually completely soundproof, windowless, and "made from a secret material which is designed to keep emissions in and listening devices out." The BBC quotes Phil Lago, whose company, Command Consulting Group, regularly supplies SCIFs to government agencies, who explains that a "ring of electronic waves" ensures that only signals from an encrypted satellite phone can get in and out.
Apparently, the President never travels without his SCIF, which is surprisingly portable. According to Lago, "You can usually fit them into two large foot lockers and that's most of the equipment you need."
The exact specifications of these mobile security pods are top secret, and for most of us, this photo will be the closest we ever get to a SCIF. James Bond, eat your heart out!

According to SciDev.Net, “swarming micro air vehicles” might soon be deployed over disaster areas to set up emergency wireless networks. Developed by scientists at the Swiss Federal Institute of Technology, these flying robots will be “emitting a wireless signal” to establish “temporary radio or mobile communication networks to coordinate the search for survivors.”
“To distribute the vehicles effectively above a designated zone,” the article goes on, the research team “took inspiration from the way ants leave chemical trails to guide colonies to sources of food. Some of the vehicles hover in small circles linked to the location of rescuers and the other vehicles navigate around these markers.”
Elsewhere and earlier, we learned from Wired that, should dictators cut off their country from the internet, there are ways to restore connectivity to the populace. The U.S. military, for instance, has the Commando Solo, a cargo plane converted into an “airborne broadcasting center” that “hypothetically” can boost Wi-Fi bars in bandwidth-denied areas to full strength. Any of the military's aircrafts can be converted into “cell towers in the sky” by attaching cellular pods to their wings or bellies.
To this arsenal, one can supposedly add the above flying robots. When the switch is turned off, they'll be released from their roost to swarm over revolutionary spaces to churn up an electromagnetic storm of Facebook schedules, retweets and Anderson Cooper's adoring visage.
But instead of hovering over disaster and conflict areas, how about urban and rural dead spaces or in even more remote locales? And instead of drones and toy airplanes, you conscript pigeons, starlings and other flying weeds into a wi-fi network of cyborg fauna?
This network needn't be online all the time. The birds, after all, need some rest. So you simply let them loose, say, during rush hour to temporarily augment the network.
One imagines urban homesteaders converting a water tank into an aviary for their robo-starlings, next to their urban apiaries, urban chicken coops and urban farming tool shed. When they need to communicate with other urban homesteaders, either nearby or in another Detroit-like ruin pornscape, they only need to open the hatch. It's an artisanal wi-fi for networked off-grid living.
In order to lessen e-waste, each starling is equipped with a homing beacon, which will signal home should the animal die in flight. The homesteader simply has to trace the electronic beeps to collect the carcass and its outfittings. In the meantime, the beacon will be powered by the decaying organic matter.
Many decisions made in our everyday lives are influenced by expert advice, from hairstyles to insurance policies. Yet, millions of decisions are made on a daily basis and instantly expressed through our own facial expressions without any preconceived external reassurance. We continuously strive to project a desired physical self image of ourselves, sometimes requiring most of our cognitive resources, and paradoxically, this daily challenge has a big impact on our lives.
