Remembering Vimy Ridge

The_Battle_of_Vimy_RidgeHello all! Today has been rather a busy one, and show’s no signs of slowing down just yet! In spite of that, I would be remiss if I did not take the time to acknowledge the rather special anniversary which falls on this day, of which some people may not be aware. You see, today is the 96th anniversary of the Battle of Vimy Ridge, a major event in my nation’s history and a defining moment for all Canadians.

Though many people outside of Canada may not know much about it, the Battle of Vimy Ridge was one of the most significant battles of World War I and a key moment in Canada’s history. Taking place between April 9th and 14th of 1917, it was not only a Canadian-led offensive, it was also the only Allied offensive victory in the war to date. And just as importantly, we in Canada consider it a defining moment in our history, when our country ceased being a colony and became a nation.

Battle_of_Arras_-_Vimy_Ridge_mapSurprising then that it is often considered a footnote to the larger campaign known as the Battle of Arras or the Nivelle Offensive, one of many disastrous offensives fought by the Allied armies during the war. Like all offensives of its kind, the purpose of the assault in the north-eastern region of France was to break the stalemate that had existened between the Allied and German lines since 1915.

It was believed that if this could be achieved, the numerically inferior German forces would finally be beaten and the war ended. And after so many bloody battles and worsening situations on home front – with shortages setting in and morale running short – the allies were desperate for their big breakthrough. Relying on armies fielded by the French, British, and all her dominions – Newfoundland, New Zealand, and Canada – the attack would take place in several key sectors along the Western Front.

vimy-ridge-875While the French struck at German positions along the Chemin des Dames ridge, and the British and most of the Dominion armies struck at positions around the town of Arras, the Canadian Corps – led by General Arthur Currie – was to take the highground known as Vimy Ridge. Despite promises of a speedy battle after a massive bombardment, the French made little gains against the dug-in defenders and lost almost 200,000 men. The British fared slightly better, achieving some gains but at the high cost of 158,000 men.

Only the Canadians achieved their objectives completely and promptly, taking the Ridge in just three days and with acceptable losses. Of the five divisions totaling nearly 170,000 men, only 3,598 were killed with another 7000 wounded. On the other side, the Germans – who were well dug-in and defending an elevated position – suffered at least as many killed and wounded, plus an additional four thousand captured. This was made ever more impressive considering that the French and British, during a previous attempt to take the Ridge, had lost a good 150,000 men.

This was unprecedented for a World War I battle, and earned the Canadian Corps the status of elite “Shock Troops”. For the remainder of the war, Arthur Currie and the soldiers under his command would be the ones who were seen as being able to “get things done”. During the battle of Passchendale, a brutal, bloody, muddy offensive, the Canadians were called in to accomplish the offensive after the British efforts faltered. During the final 100 days of the war, when the German lines were collapsing, the Canadians led the way for every single push.

And yet, all of this was made possible due to one simple thing: sound planning. As the first offensive action that Canadian commanders were able to plan on their own, they took advantage of some rather novel ideas and technologies to overcome the problems of trench warfare. These included the rather revolutionary concept of using triangulation and wind measurements to determine the position of enemy artillery, and destroy them ahead of time.

battle_of_vimy_ridge_field_gun_firingCreeping barrages were also planned to give the advancing troops continuous fire support, rather than simply laying down a barrage and then stopping it before the infantry began to march. This tactic had already been proven ineffective, as the Germans simply dug in deeper to avoid preemptive barrages and also had time to emerge from their dugouts once the shells stopped falling to shoot at the advancing troops. By timing the artillery with the advance, any Germans brave enough to fire on the Canadian Corp risked being blown to pieces.

But most importantly, the planned offensive had been meticulously planned for month. Spotters mapped out 80 percent of the Ridge in advance, full-scale replicas of the terrain were built to rehearse unit tactics, and individual officers were assigned maps and time tables. All of this was a break from conventional philosophy, which held that troops did not need to be familiar with the grand strategy and should march as one.

Model_reproduction_of_German_linesThough many a military “expert” of the time found much of this suspect, they admitted dubiously that the Canadians’ plan couldn’t be any worse than the British tactics at the Somme, which cost the lives of 623,907 troops, 24,000 of which were Canadian. As such, the Canadian Corps got the go ahead. For weeks, Canadian and British artillery began pounding the German positions in preparation for the assault. Then on April 9th, an Easter Monday morning amidst rain and freezing cold, the Canadian Corps struck.

By the end of the first day, they had accomplished most of their objectives, but fighting and consolidation would continue for another four days and Canadians mopped up the German positions and took prisoners. When the dust had settled, the valour of the troops, the originality of the plan, and the success where larger, more established armies had failed all contributed to a new nation’s pride. The battle was hailed as the first allied success of the long war, achieved mostly due to the innovation of using a creeping, continuous massive artillery barrage to protect squads of advancing troops. Both sides used the tactic in future battles.

Vimy RidgeToday, the Canadian National Vimy Memorial stands as a proud reminder of what Canadians accomplished at Vimy and throughout the war. As a young nation, nominally independent but still very much tied to the British Crown, we had done what others could not and earned a reputation as stalwart soldiers and faithful allies that is still acknowledged to this day. The monument, as well as many of the wartime features of the Ridge, are maintained by an army of committed volunteers and government assistance.

And I for one very much look forward to visiting it in the spring of 2014, when the centennial of World War I is being marked all over Europe, and legions of Canadians and other nationals descend on Flanders and Northern France in order to pay their respects. In addition to the many monuments which mark the landscape, it is a testament to the futility of war, but also a symbol of a nation born in fire.

Today, it is especially important that we remember what happened not only at Vimy, but all over Europe and the world at large during those fateful years. Since the last living veteran of World War I, a British man named Florence Green, died on February 4th 2012 at the aged of 110, there is no one left who experienced that terrible war directly. And as we near the 100 year marker of the Great War and the battle that defined Canada as a nation, I hope and pray the lessons will not be forgotten! They simply cannot afford to be repeated…

The Future is Here: The Smart Bandage!

electronic_skin_patchWith recent advances being made in flexible electronics, researchers are finding more and more ways to adapt medical devices to the human body. These include smart tattoos, stretchable patches for organs, and even implants. But what of band-aids? Aren’t they about due for an upgrade? Well as it happens, a team of chemical engineering at Northeastern University are working towards just that.

Led by associate professor Ed Goluch, the team is working towards the development of a “smart bandage” that will not only dress wounds, but can monitor infections and alert patients to their existence. Based around an electrochemical sensor that is capable of detecting Pseudomonas aerug­i­nosa – a common bacteria that can kill if untreated – this bandage could very prove to be the next big step in first aid.

smart_bandaidAccording to Goluch, the idea came to him while he was studying how different bacterial cells behave individually and he and his colleagues began speaking about building other types of sensors:

I was designing sensors to be able to track individual cells, measure how they produce different toxins and compounds at the single-cell level and see how they change from one cell to another and what makes one cell more resistant to an antibiotic.

Naturally, addition research is still needed so that smart band-aids of this kind would be able to detect other forms of infections. And Goluch and his colleagues are quite confident, claiming that they are adapting their device to be able to detect the specific molecules emitted by Staphylococcal – the bacteria responsible for staph infections.

???????????????????????????????So far, Goluch and his team have tested the system with bacteria cultures and sensors. The next step, which he hopes to begin fairly soon, will involve humans and animals testing. The professor isn’t sure exactly how much the sensor would cost when commercialized, but he believes “it’s simple enough that you’d be able to integrate it in a large volume fairly cheap.”

At this rate, I can foresee a future where all first-aid devices are small patches that are capable of gathering data on your wounds, checking your vitals, and communicating all this information directly to your PDA or tablet, your doctor, or possibly your stretchable brain implant. I tell ya, it’s coming, so keep your apps up to date!

News From Space: The NASA-Funded Fusion Rocket

fusion-rocket-university-of-washington-640x353NASA scientists have been saying for some time that they plan to send a manned mission to Mars by 2030. At the same time, space adventurist Dennis Tito and his company Inspiration Mars want to send a couple on a flyby of the Red Planet in 2018. With such ambitions fueling investment and technological innovation, its little wonder why people feel we are embarking on the new era of space exploration.

However, there is one sizable problem when it comes to make the Mars transit, which is the wait time. In terms of Tito’s proposed flyby, a trip to Mars when it is in alignment with Earth would take a total 501 days. As for NASA’s round-trip excursions for the future, using current technology it would take just over four years. That’s quite the long haul, and as you can imagine, that longer transit time has an exponential effect on the budgets involved!

Mars_landerBut what if it were possible to cut that one-way trip down to just 30 days. That’s the question behind the new fusion rocket design being developed at the University of Washington and being funded by NASA. Led by John Slough, this team have spent the last few years developing and testing each of the various stages of the concept and is now bringing the isolated tests together to produce an actual fusion rocket.

The challenge here is to create a fusion process that generates more power than it requires to get the fusion reaction started, a problem which, despite billions of dollars of research, has eluded some of the world’s finest scientists for more than 60 years. However, researchers continue to bang their head on this proverbial wall since fusion alone – with its immense energy density – appears to be the way of overcoming the biggest barrier to space travel, which is fuel weight and expense.

spacecraft_marsUltimately, the UW fusion rocket design relies on some rather simple but ingenious features to accomplish its ends. In essence, it involves a combustion chamber containing rings made of lithium and a pellet of deuterium-tritium – a hydrogen isotope that is usually used as the fuel in fusion reactions. When the pellet is in the right place, flowing through the combustion chamber towards the exhaust, a huge magnetic field is triggered, causing the metal rings to slam closed around the pellet of fuel.

These rings then implode with such pressure that the fuel compresses into fusion, causing a massive explosion that ejects the metal rings out of the rocket and at 108,000 km/h (67,000 mph) and generating thrust. This reaction would be repeated every 10 seconds, eventually accelerating the rocket to somewhere around 320,000 km/h (200,000 mph) — about 10 times the speed of Curiosity as it hurtled through space from Earth to Mars.

NASA_fusionchamberHowever, things still remain very much in the R&D phase for the fusion rocket. While the team has tested out the imploding metal rings, they have yet to insert the deuterium-tritium fuel and propel a super-heated ionized lump of metal out the back at over 100,000 kilometers and hour. That is the next – and obviously a very, very – big step.

But in the end, success will be measured when it comes to two basic criteria: It must work reliably and, most importantly, it must be capable of generating more thermal energy than the electrical energy required to start the fusion reaction. And as already mentioned, this is the biggest challenge facing the team as it is something that’s never been done before.

However, most scientific minds agree that within 20 years at least, fusion power will be possible, and the frontiers it will open will be vast and wonderful. Not only will we be able to fully and completely lick the problem of clean energy and emissions, we will have rockets capable of taking us to Mars and beyond in record time. Deep space flight will finally become a possibility, and we may even begin considering sending ships to Alpha Centauri, Bernard’s Star and (fingers crossed!) Gliese 581!

Movie Trailer Monday: Riddick!

riddick_vin_dieselGuess what? In this new age of reboots, relaunches and reimaginings, it seems that not a single cult classic is immune. Case in point, the eponymously named sequel Riddick, which is set for release in early September of 2013. Though there are minimal hints provided concerning the plot of this third installment, it seems clear at this point that Riddick is once again on the run from mercenaries and ends up on a planet teeming with hostile life.

Going back to their origins, I take it? Personally, I would prefer seeing what happened after Riddick took control of the entire Necromonger army. And if some tells me this is what followed, i.e. he chose to ditch all that and go back on the run, I’ll totally write this movie off! You can’t tell me he likes being hunted by mercs and living hand to mouth THAT much! I mean there’s recidivism and then there’s just plain dumb!

Enjoy the clip!

The Future is Here: Web-Based “Brain” for Robots

AI_robotMy gratitude once again to Nicola Higgins for beating me to the punch yet again! I hope she doesn’t mind that I’m totally posting a separate article, but something like this is just too good to reblog! In what is sure to excite Singularitarians and Futurists and scare the holy bejeezus out of technophobes and those fearing the Robopocalypse, a new web-based artificial brain went online recently, allowing robots to share information and seek help whenever they need it.

It’s called Rapyuta (or the The RoboEarth Cloud Engine), a part of the European Robo Earth project that began in 2011 with the hope of standardizing the way robots perceive the human world. Basically, it is an online database that robots can consult in order to get information about their world and help them make sense of their experiences, post-activation.

robot_internetThe name Rapyuta is taken from the Japanese film by Hayao Miyazaki known as Castle in the Sky, and refers to a place where all the robots live. The project, which involves researchers at five separate European research labs, has produced the database as well as software that robot owners can upload to their machines so that they can connect to the system at any time.

You might say the “brain” is an expression of sympathy for robots, who are no doubt likely to find the world intimidating and confusing once they come online. Now, instead of every robot building up their own idiosyncratic catalog of how to deal with the objects and situations it encounters, Rapyuta would be the place they ask for help when confronted with a novel situation, place or thing.

googlecarIn addition, the web-based service is able to do complicated computation on behalf of a robot. For example, if it needs to work out how to navigate a room, fold an item of clothing or understand human speech, it can simply do an online consultation rather than try to figure it out on its own. In addition, it is believed that robots will be cheaper thanks to this system since it will mean they won’t need to carry all their processing power on board.

Looking ahead, Mohanarajah Gajamohan, technical head of the project at the Swiss Federal Institute of Technology in Zurich, says that the designers believe the system could be particularly useful for drones, self-driving cars or other mobile robots who have to do a lot of number crunching just to get round.

internetDr Heico Sandee, Robo Earth program manager at the Dutch University of Technology in Eindhoven, also highlighted the economic benefits of this new concept. “On-board computation reduces mobility and increases cost,” he said, adding that as wireless data speeds increase, more and more robotic thinking could be offloaded to the web.

But above all, the aim here is about integration. As robots become more and more common and we human beings are forced to live with them amongst us, there could be difficulties. Without access to such a database, those involved in the project and roboticists at large fear that machines will remain on production lines and never live easily alongside humans.

robots_earthAs for those who support and await the Technological Singularity, this could be one such means through which it is achieved. The idea of machines that are capable of network and constantly upgrade their software is a step in the direction of machines that are capable of self-assembling, evolving and upgrading themselves constantly, which will basically result in a rate of progress that we can currently predict.

But on the other side of the debate, there are those who say this smacks of a Skynet-like supercomputer that could provide machines with the means to network, grow smarter, and think of ways of overthrowing their human masters. While I don’t consider myself the technophobic sort, I can certainly see how this invention could be perceived that way.

robots_ideaCreating a means for robots to communicate and contribute to a growing sense of knowledge, effectively letting them take ownership of their own world, does seem kinda like the first step in creating a world where robots no longer need human handlers. Then again, if we’re going to be creating AI, we might want to consider treating them like sentient, dignified beings beforehand, and avoiding any “controversy” when they begin to demand them later.

Gotta admit, when it comes to technophobes and paranoiacs, this kind of stuff is certainly fertile territory! For more information on the Rapyuta Engine, simply click here. And may God help us all!

The Walking Dead Season 4: A Look Ahead

The-Walking-Dead-Season-4-RenewalIt’s no secret that fans were a little surprised with the season finale of The Walking Dead. What with from the rather abortive assault on the prison, the way the Governor just up and disappeared, and the way the people of Woodbury were then incorporated into the prison community, there appeared to be a lot of unanswered questions, unfinished business and untied loose ends.

Perhaps in response to this, Robert Kirkman, the cast and producers of AMC’s The Walking Dead have released a preview video of what lies in store for season four. Through the course of clips, snippets, and interviews, it is revealed that the new season will have plenty of surprises and promises that the various threads that were left open in season three would ultimately be tied. Given my disappointment with how season three ended, I certainly hope they are telling the truth!

[Spoilers Ahead! Cease reading if you haven’t seen the finale or don’t want to know what’s coming!]

First and foremost on people’s minds is the issue of the Governor. After snapping and shooting his own people, he kind of just took off into the sunset, didn’t he? And then there’s the matter of Carl Grimes, the budding psychopath who’s latest exploits include shooting a man in cold blood. Where is he heading? Toward redemption, or straight to the loony bin? Co-executive producer Denise Huth had this to say on those subjects:

The Governor is still out there. The war is not over. Rick and our group here won the first round and scared him off… Carl’s changing. It’s a huge wake-up call for Rick. And it’s a big fear for him moving into the next season. Is Carl going to be Rick, or is Carl going to be the Governor? And right now Carl could go either way.

In addition, Hurd was sure to indicate that there would be plenty of problems on the home front as well, not the least of which would arise from the way Woodbury and the prison had integrated at the end of season three:

What’s going to happen as these two groups who literally were at war with each other moments before, how are they going to integrate?

In an interview with IGN, Kirkman also had much to say, claiming that the prison will remain a major part of season four, but that there would also be some major changes. For starters, Rick will be facing some of the same issues the Governor dealt with since he now has to lead a larger group that needs more food and supplies than their tight-knit team. And of course, he let viewers know that the Governor would remain a threat.

A bigger group brings with it bigger problems. They are certainly going to need a lot more resources, and they already have a lot of rebuilding to do, just from the things that happened in this battle between Woodbury and the prison. I don’t think there’s going to be a shortage of conflict and danger coming into the fourth season, despite the fact that they are still in the prison…

I’ll say that there are a lot of familiar elements that are remaining. Michonne is still around, Rick and his group are still in the prison, the Governor’s still out there… so there are a lot of things that are carrying over from Season 3 to Season 4, but I can’t stress how different things are going to be.

There are going to be some radical changes to those elements that are going to bring in a lot of new storytelling. While [Season 4] does seem somewhat familiar, it’s going to be vastly different from Season 3.

In addition, Kirkman indicated that in the next season, the world will be expanded well beyond that of the familiar settings established in season three:

We will be getting into more world building, more civilization being brought back. A little bit more of a bigger sense of community.

Well, for those of disappointed in the ending of season three, but generally impressed with the direction the show has been taking since season two, I think it’s fair to say the intrigue level has gone up. Rest assured, there’s plenty of material to be adapted from the original comic, and even without the source material, the zombie apocalypse is some pretty fertile territory! Just seven months to go before the October 2013 premiere, people!

Towards a Cleaner Future: Fuel Cell Breakthrough!

hydrogen-fuel-cellOne of the greatest challenges facing renewable energy is making it affordable and cost effective, to the point where it will naturally offset such sources as fossil fuels and coal. And when it comes to hydrogen fuel cells, a recent development may have accomplished just that. Quite surprising when you consider that it came from Alberta, home of the Athabasca Oil Sands and an output of roughly 4 million barrels of crude a day.

It all happened late last month, when researchers at the University of Calgary published a paper in the Journal of Science that they had come up with a much cheaper and easier way to build an electrolyzer. This is the device that uses electricity to break up water into hydrogen and oxygen, which are then used to power hydrogen fuel cells.

Picture shows the refuelling hydrogen syFor some time now, these fuel cells have been considered the most promising means of powering automobiles with a clean, renewable energy source. By recombining the two basic elements of hydrogen and oxygen, energy is generated and the only waste product is water. The only difficulty is the means of production, as electrolyzers often depend on expensive and sometimes toxic metals.

The most common of current methods involves the use of expensive rare earth metals in precise crystalline arrangements to catalyze, or speed up, the reaction. But with the new process developed by Chris Berlinguette and Simon Trudel comes into play, which involves catalyzers built out of common metals without the need for the crystal structure, the process will not only be vastly simplified but extremely cheaper.

solar_arrayBased on the estimates presented in their paper, Trudel and Berlinguette estimate that their new eletrolyzer will deliver results comparable to current techniques but at a cost of about one-one-thousandth the norm. The implications for clean, renewable energy,  such as wind or solar generators, could be enormous. Not only would it be far cheaper and more efficient, there would be far less toxic waste materials produced.

Not only that, but another major stumbling block for clean energy could be overcome. As is the case with just about any type of renewable power source – wind, solar, tidal – is that it is dependent on conditions which limit when power can be generated. But stored hydrogen energy can be used at anytime and could easily replace gas and coal, just as long as the production process is cost-effective.

hydrogencarAs Berlinguette himself pointed out, making and electrolyzer cost-effective means being able to produce power on demand and to scale:

If you think of a wind turbine producing electricity at two o’clock in the morning, there’s no one around to actually use that electricity, so it just gets dumped. If you could set that up with an electrolyzer, you could convert that electricity into hydrogen, then the next day, when there is demand, you can sell that electricity at a premium during periods of high demand.

In anticipation of the inevitable investment this will attract, Berlinguette and Trudel have already formed a company called FireWater Fuel Corp. to market their work and expect to have a commercially available electrolyzer by next year. So for those of you with money to invest and a socially-responsible, environmental outlook, get out your check books out and be prepared to invest!

The Future is Here: The Air Scrubbing Skyscraper!

aircleaning_skyscraperAir pollution has always been a problem in urban centers. But with the massive industrialization and urban expansion taking place in some of the most heavily populated regions of the world (China and India being foremost), the issue of how to deal with increasing emissions is especially important. And more and more, researchers and environmentalists are considering options that hits air pollution where it lives.

Two such individuals are Danny Mui and Benjamin Sahagun, a pair of architects who have devised a rather novel concept for dealing with the thick layers of carbon dioxide pollution that are so common to major urban centers. In essence, it is a pair of buildings that scrub CO2 emissions from the air, and thus marries the concept of Carbon Capture technology to urban planning.

artificial_trees1Dubbed the CO2ngress Gateway Towers, the concept involves two crooked buildings that are outfitted with a filtration system. This system then feeds the captured CO2 to algae grown in the building which then converts into biofuels for use in vehicles. In this respect, it is not unlike the artificial tree concept designed by Klaus Lackner, director of the Lenfest Center for Sustainable Energy at Columbia University.

Much like these “trees”, the carbon capture technology involves using a entirely natural process to absorb CO2 from the air and then combine it with water, thus causing a chemical reaction that results in a fossil fuel precursor which can easily be converted. This fuel can then be consumed as gasoline or ethanol, thus giving people the ability to keep burning fossil fuels while they research cleaner, more sustainable sources of fuel.

aircleaning_skyscraper3Ultimately, the idea here is not to offer a be-all, end-all solution to the problem, but rather to buy the human race time to clean up its act. And by ensuring that carbon capture technology is available in large urban dwellings, they are looking to ensure that one of the many symptoms of urban sprawl – i.e. large urban dwellings – are part of the solution.

Said Mui and Sahagun on the Council on Tall Buildings and Urban Habitat (CTBUH) website:

The scrubbers are the first step in a process that generates fuel for a fleet of eco-friendly cars for building residents. The system raises public awareness of air pollution and its impact on the health of Chicagoans.

aircleaning_skyscraper1Aside from the scrubbers, the buildings boast some other impressive features to cut down on urban annoyances. These include the “double skin facade”- two layers of windows – that can cut down on outside traffic noise. In addition, the spaces on either side of the buildings’ central elevator core can be used as outdoor terraces for residents.

Apparently, Mui and Sahagun worked on the project while students at the Illinois Institute of Technology, where it earned them an honorable mention in the 2012 CTBUH student competition. According to Mui, they created the structure after the semester ended, but there are no immediate plans to build it.

aircleaning_skyscraper2However, given the growing interest in arcologies and urban structures that reduce our impact on the environment, it is likely to garner serious interest very soon. Especially in China, where air pollution is so severe that it causes up to 750,000 deaths from respiratory illness a year and cities are still growing, buildings like this one could easily become the stone that kills two birds.

Of Cybernetic Hate Crimes

Google Glass_CalaLast week, a bar in Seattle banned the use of Google Glass. The pub declared on their Facebook page that if anyone wanted to order a pint, they had better remove their $1500 pair of augmented reality display glasses beforehand. Citing the glasses potential to film or take pictures and post them on the internet, the bar owner unflinchingly declared that “ass-kickings will be encouraged for violators.”

This is the second case of what some are dubbing a new wave of “Cybernetic hate crimes”. The first took place back in July 2012 when Steve Mann, a Canadian university professor known as the “father of wearable computing”, was physically assaulted at a McDonalds in Paris, France. In this case, three employees took exception with his wearable computer and tried to physically remove it, an impossibility since it is permanent screwed into his head, and then three him out of the restaurant.

steve-mann1Taken together, these two incidents highlight a possible trend which could become commonplace as the technology grows in use. In some ways, this is a reflection of the fears critics have raised about the ways in which these new technologies could be abused. However, there are those who worry that these kinds of fears are likely to lead to people banning these devices and becoming intolerant to those who use them.

By targeting people who employ augmented reality, bionic eyes, or wearable computers, we are effectively stigmatizing a practice which may become the norm in the not too distant future. But Google responded to the incident with optimism and released a statement that cited shifting attitudes over time:

It is still very early days for Glass, and we expect that as with other new technologies, such as cell phones, behaviors and social norms will develop over time.

smartphonesYes, one can remember without much effort how similar worries were raised about smartphones and camera phones not that long ago, and their use has become so widespread that virtually all doubts about how they might be abused and what effect they would have on social norms have gone quiet. Still, doubts remain that with the availability of technologies that make it easier to monitor people, society is becoming more and more invasive.

But to this, Mann, responds by raising what he had always hoped portable computing would result in. Back in the 1970’s when he first began working on the concept for his EyeTap, he believed that camera-embedded wearables could be both liberating and empowering. In a world permeated by security cameras and a sensory-sphere dominated by corporate memes, he foresaw these devices a means for individuals to re-take control of their environment and protect themselves.

EyeTapThis was all in keeping with Mann’s vision of a future where wearable cameras and portable computers could allow for what he calls sousveillance — a way for people to watch the watchers and be at the ready to chronicle any physical assaults or threats. How ironic that his own invention allowed him to do just that when he himself was assaulted!

And in the current day and age, this vision may be even more important and relevant, given the rise in surveillance and repressive measures brought on in the wake of the “War on Terror”. As Mann himself has written:

Rather than tolerating terrorism as a feedback means to restore the balance, an alternative framework would be to build a stable system to begin with, e.g. a system that is self-balancing. Such a society may be built with sousveillance (inverse surveillance) as a way to balance the increasing (and increasingly one-sided) surveillance.

Raises a whole bunch of questions, doesn’t it? As the issue of dwindling privacy becomes more and more of an issue, and where most people respond to such concerns by dredging up dystopian scenarios, it might be helpful to remind ourselves that this is a form of technology that rests firmly in our hands, the consumers, not those of an overbearing government.

google_glass_banBut then again, that doesn’t exactly ease the fears of a privacy invasion much, does it? Whether it is a few functionaries and bureaucrats monitoring us for the sake of detecting criminal behavior or acts of “sedition”, or a legion of cyberbullies and gawking masses scrutinizing our every move, being filmed and photographed against our will and having it posted is still pretty creepy.

But does that necessitate banning the use of this technology outright? Are we within our rights, as a society, to deny service to people sporting AR glasses, or to physically threaten them if they are unable or unwilling to remove them? And is this something that will only get better, or worse, with time?

The Future is Here: The Invisibility Cloak!

quantum-stealth-fieldInvisibility cloaks have long been considered the next frontier of modern warfare. With stealth aircraft, stealth ships and even stealth tanks in service or on well on their way, it seems like the time is ripe for a stealth soldier. But difficulties remains. Whereas cloaking planes, ships and tanks is a matter of simply coating them in materials that can obscure them from radar and thermal imagine, soldiers need camouflage that can move, bend and flex with them.

In recent years, the efforts to produce a working “invisibility cloak” have born considerable fruit. And while most of these took the form of large, cumbersome, desk-mounted constructions that were more of a proof of concept for the material being tested, they did demonstrate that the technology itself worked. This was certainly true of the “cloak” which was created by scientists at Duke University in November of 2012.

INVISIBILITY-CLOAKAnd then came news the following month that a Canadian company named Hyperstealth developed a material that renders the wearer “completely invisible by bending light waves around the target.” Known as “Quantum Stealth”, this true cloak is an apparent follow-up to their SmartCamo – a material that could reportedly adjust its camouflage markings to match its surroundings – that was released at the International Camouflage Symposium in 2010.

Unfortunately, due to security reasons, little was ever known about SmartCamo other than its reported abilities. The same holds true for Quantum Stealth, which the company has been forced to remain clandestine about due the demands of the US Army, to whom they are contracted. So until such time as it enters widespread use, the details and inner workings of the technology will remain inaccessible.

In addition to being composed of conventional materials, their new cloak measures a mere 166 micrometers thick and is capable of obscuring an object from multiple directions at once. And though it may not be able to render a soldier truly invisible, it does render them all but invisible to radar detection, which is the intent here.

The fabrication process involved placing a 66µm-thick sheet of carbon (or a metascreen) onto a a 100µm-thick sheet of flexible polycarbonate. The copper is patterned specifically so that the scattered light from the cloak and the cloaked object cancel each other out. This flexible sheet also allows the cloak to conform to the shape of the object, or person, and provides cloaking from microwave radiation from all directions.

After all, microwaves, infrared and visible light are all physically identical; they are just waves that oscillate at different frequencies. And their design would be more capable of doing this than any cloak composed of metamaterials.

Still, size and scale are still an issue. Whereas their new patterned material scattering technique is capable of hiding an object from multiple directions, it also inversely scales with wavelength. That means that it is only capable of hiding micrometer-scale objects from 400-800THz of visible light. Still, this is exciting news and a step in the right direction!

Before we know it, stealth troopers could be marching all over the planet, invisible to the naked eye and any means of radar detection… Holy crap, what a scary thought! Is it too late to rethink this technology?
