The Future of Disaster Relief: The Ecos PowerCube

EcosPowerCube-640x353One of the greatest challenges to humanitarian aid and disaster relief is the task of getting services to where they needed the most. Whether it’s hurricanes, earthquakes, mudslides, or wildfires; getting electricity, water, and other utilities up and running again is a tough task. And with every moment that these services are not available, people are likely to die and humanitarian crises ensue.

However, Ecosphere Technologies – a diversified water engineering and environmental services company – believes it’s designed a solution in the form of their new PowerCube. This self-contained, mobile apparatus is designed to deliver solar power to off-grid areas along with water purification facilities and WiFi base stations — all in a single package that is the size of a shipping container.

https://i0.wp.com/www.extremetech.com/wp-content/uploads/2014/06/disaster-lg-1.jpgThe Ecos PowerCube will be available in three sizes that are designed to fit into 10-foot, 20-foot, and 40-foot shipping containers. The largest models will be capable of generating up to 15kW of power, which will be parceled between providing electrical hook-ups, water treatment and internet access. And they will also serve as temporary shelters, providing temporary sleeping quarters or medical stations.

What is especially innovative about the design is the use of fold-out solar panels, which allow for significant power generation without compromising on the handy space-saving form. Deployed, the Cube is able to maximize its solar-absorbing surface area; but packed up, its small enough to fit into a shipping container and be deployed around the world. However, the design also comes with its share of drawbacks.

powercube-howFirst, there’s the apparent lack of batteries, which means the Cubes will only be able to provide power while the sun is shining. This is crucial since time is often of the essence in disaster areas, with windows for treating wounds and rescuing the buried and trapped lasting typically less than three days. Second, the 15kW generator is rather meager compared to what a diesel generator can produce – between 600kW and 1.7MW.

This means, in essence, that some twenty or so PowerCubes would have to be shipping to a disaster area to equal the electrical capacity of a single large diesel generator. And the intermittency problem is certainly an issue for the time being, unless they are prepared to equip them with high-capacity batteries that can quickly absorb and hold a charge (some graphene or integrated Li-ion batteries should do it).

https://i0.wp.com/www.extremetech.com/wp-content/uploads/2014/06/military-lg-2.jpgIn the meantime, it is still a crafty idea, and one which has serious potential. Not only do disaster areas need on-site water distribution – shipping it in can be difficult and time consuming – but internet access is also very useful to rescue crews that need up-to-date information, updates, and the ability to coordinate their rescue efforts. And military installations could certainly use the inventions, as they would cut down on fuel consumption.

Still, refinements will need to be made before this is a one-fit solution problem of what to do about disaster relief and fostering development in densely populated areas of the world where things like water-treatment, electricity, and internet access is not readily available.

Cyberwars: Latest Snowden Leaks

FRANCE-US-EU-SURVEILLANCE-SNOWDENThe case against the NSA’s program of cyberwarfare and espionage has become somewhat like an onion. With every new revelation, the matter becomes more stinking and fetid. Certainly, the first release of classified NSA documents – which dealt with the US’s ongoing cyberwarfare against China and other nations – was damaging to the agency’s image. But it has been the subsequent publication of documents that deal with domestic surveillance that have been the most damning.

According to Snowden, he was motivated to leak this information because of the troubling case of hypocrisy inherent in the NSA programs. And in the lastest leak, Snowden has now confirmed that at least five Muslim-Americans – including prominent lawyers, a civil rights leader and academics – were the subject of years’ worth of surveillance by both the FBI and the National Security Agency.

under_surveillance_full_v2Among the targets were Nihad Awad, the executive director of the Council on American-Islamic Relations – the top Muslim-American civil rights organization in the United States – and Faisal Galil, a longtime Republican operative and former Bush Administration official who worked for the Department of Homeland Security and held a top-secret security clearance during the time he was under surveillance.

Also among the American targets was Asim Ghafoor, an attorney for the al-Haramain Islamic Foundation who who has represented clients in terrorism-related cases . He is also the man who famously discovered in 2004 that he and his clients were under surveillance after the Treasury Department mistakenly released to him a document listing calls he’d made to his clients.

wire_tappingOther targets include Hooshang Amirahmadi, an Iranian-American professor of international relations at Rutgers University and Agha Saeed, a former political science professor at California State University who champions Muslim civil liberties and Palestinian rights. All of the targets appear to have been singled out because of their Muslim backgrounds and their activities either defending Muslim clients or on behalf of various causes.

The individuals appear on an NSA spreadsheet in the Snowden archives called “FISA recap”—short for the Foreign Intelligence Surveillance Act. Under that law, the Justice Department must convince a judge with the top-secret Foreign Intelligence Surveillance Court that there is probable cause to suspect of an American of being engaged in or abetting terrorism, espionage, or sabotage against the US.

FILE PHOTO  NSA Compiles Massive Database Of Private Phone CallsThe authorizations must be regularly renewed by the court for the surveillance to remain in effect, usually every 90 days for U.S. citizens. In none of these cases were the individuals singled out for surveillance because they were suspected of committing or planning a crime. And six years after the period the document covers, none of them has been charged with any crime related to the surveillance.

Greenwald says the revelations offer a more detailed look at who the government is targeting. Although there are some Americans on the list who have been accused of terrorism, the five highlighted in The Intercept piece have all led what appear to be law-abiding lives. As Greenwald explained:

This is the first time that there’s a human face on who the targets are of their most intrusive type of surveillance. [H]ere you really get to see who these people are who are the people worthy of their most invasive scrutiny. I think it’s important for people to judge—are these really terrorists or are these people who seem to be targeted for their political dissidence and their political activism?

 

faisal_gillAll of these five individuals identified in the article has gone on record to vehemently deny any involvement in terrorism or espionage. Outside of their ancestry, there appears to be no justification whatsoever for the surveillance. Faisal Gill, whose AOL and Yahoo! email accounts were monitored while he was a Republican candidate for the Virginia House of Delegates, had this to say when interview by The Intercept:

I just don’t know why. I’ve done everything in my life to be patriotic. I served in the Navy, served in the government, was active in my community—I’ve done everything that a good citizen, in my opinion, should do.

Ghafoor was also of the opinion that profiling had everything to do with him being targeted for electronic surveillance. When told that no non-Muslim attorneys who defended terror suspects had been identified on the list, he replied:

I believe that they tapped me because my name is Asim Abdur Rahman Ghafoor, my parents are from India. I travelled to Saudi Arabia as a young man, and I do the pilgrimage. Yes, absolutely I believe that had something to do with it.

https://i0.wp.com/media.nj.com/ledgerupdates_impact/photo/2012/06/muslim-lawsuitjpg-88e364e9b8e195f4.jpgCivil liberties groups have expressed anger that the five appear to have been targeted largely for having Muslim backgrounds. One such group is the Muslim Advocates, which released the following statement shortly after the story was published:

This report confirms the worst fears of American Muslims: the federal government has targeted Americans, even those who have served their country in the military and government, simply because of their faith or religious heritage. Muslim Advocates calls on the President and Congress to take steps immediately to reform the NSA surveillance program to uphold basic privacy rights and civil liberties that the Constitution guarantees to every American, regardless of faith.

The new revelations confirm for the first time that the government targeted U.S. attorneys, sometimes without warrants. Crucially, the revelations also give targets of the domestic surveillance legal standing to sue. Snowden indicated to Greenwald last year that he included the target list in the cache of leaked documents because he wanted people who had been under such surveillance to have evidence to challenge the spying in court.

An illustration picture shows the logo of the U.S. National Security Agency on the display of an iPhone in BerlinIn the past, journalists and attorneys have tried to challenge the constitutionality of the government’s surveillance activities in court. But since the defendants did not have proof that they in particular had been targeted, the courts were forced to rule that they did not have standing. The spreadsheet, however, provides evidence of targeted surveillance for those who have now been identified.

In short, this latest revelation has provided Americans, and not just those of Muslim descent, with the means to hold the NSA and the FBI accountable for the first time. Since the historic episode known as the “war on terror” began, revelations have led to challenges and promises for reform. But in all cases, the crucial issue of whether or not these programs would be allowed to continue has been carefully sidestepped.

cyber_security2Whether it was the failure of FISA reform to reign in domestic wiretapping and data mining, or the Obama administrations endorsement of “transparent” surveillance, it seems obvious clear that an administrative solution was not in the works. But opening the way for successive lawsuits for wrongful surveillance might just prove to be more effective.

What is certain, though, is that the battle between civil liberties and surveillance in the “Digital Age” is nowhere close to being resolved. As the daily volume of data sent around the world continues to grow – from terabytes to petabytes to exabytes – there will continually be a need for monitors to watch for sinister things. And as long as they are willing to push the boundaries in the name of security, there will continue to be challenges.

Preparing for the Zombie Apocalypse!

zombies-city-and-the-crowdCurrent events not related to science, tech, and/or pop culture are not exactly my forte. But I came across this article in the new lately and could not resist passing it on. To break it down, police in West Brighton NY conducted a raid on a man’s apartment over the weekend. In the course of searching his place, they found tw0 loaded pistols – a Springfield Armory XD40 .40 cal and an American Firearms Mfg. Co. .25 cal – along with 43 loose .25 caliber rounds.

But the twist came when they asked Nelson Quinones, one of the two residents, why he was in possession of these guns, which he kept stashed in his dresser drawer and under his bed. Apparently, the man told police that he was gearing up for “doomsday” or the “zombie apocalypse”. Quinones also had a gravity knife on his person when police searched him in his apartment building’s rear parking lot, court papers allege.

https://i0.wp.com/www.transportationissuesdaily.com/wp-content/uploads/2012/06/Zombies-ahead.jpgAccording to court papers and the District Attorney, both he and Ms. Meritza Hay (who lives with him) face serious criminal charges as a result of these weapons. Both face third- and fourth-degree criminal possession of a weapon, as well as criminal possession of a firearm and possession of ammunition. But Mr. Quinone’s wife also faces more serious charges due to the fact that she was convicted of misdemeanor drug possession in 2000.

But let’s face it: the real issue here is the zombie apocalypse, isn’t it? This man was in the early stages of stockpiling weapons because he knew what was coming! And while his intentions were good, his methods were terribly flawed! So let me address those now in an open letter to Mr. Quinone. Hopefully, it will give him something to think about while he’s languishing in jail…

gun_violenceMr. Quinone, while I applaud your efforts to be prepared for the inevitable rise/return of the living/walking dead, there’s a few things you need to understand. First of all, if you’re going to go the gun route for the zombie apocalypse, a 9mm is really the only way to go. More capacity for your weapon, big enough to take out a zombie’s brain, and far more common. This is important when it comes time to scavenge.

Second, everybody knows that firearms draw the attention of zombies (aka. Walkers, aka. Biters, aka. Zack, aka. Whiskeys!). If you’re planning on having to defend yourself from them, you should be hoarding melee weapons, such as the trusty katana sword, a machete, a truncheon, or just some good old fashioned baseball bats. You really want to fortify that for a zombie fight, wrap some barbed wire around it or stud it with some nails.

See?
See? Way more effective than a gun!

Some riot armor would help too, or just some improvised protection like some leather patches stitched into a suite of armor. Zombies spread their infectious disease through bites and scratches, so something that will prevent them from your from getting grazed would be a boon. And let’s not even get into how little thought you put into the state of your transportation.

Everybody knows that in the midst of a zombie apocalypse, you’re going to need to get the hell out of dodge, so something that can address the special needs of survival on a budget is a must. Naturally, you might be tempted to get yourself a horse since these and other more traditional modes of transportation are fuel-efficient (which is a big plus in any apocalyptic scenario).

zombie_carBut horses or mules are likely to panic at the site of flesh-eating zombies and buck you. What’s more, the presence of unfetid, uncorrupted flesh tends to draw the zombies in your direction. Far better to soup up your existing vehicle into a zombie-smasher with the addition of some floodlights and a front-end plough. I believe the picture above of Robert Kirkman’s zombie car will help to illustrate.

Last, but certainly not least, is the issue of supplies. When police raided your home, did they find a huge collection of fresh water containers, dehydrated foods, C-rations, vitamin supplements, batteries, solar cookers, camping stoves, propane tanks, or signal flares? No, they didn’t! These should be your FIRST priority, not some hand guns! What were you planning – to waiting for the crisis to hit before running down to the mall and hoarding with the rest of us?

Now that's what a storeroom looks like!
Now that’s what a storeroom looks like!

He who plans for the apocalypse ahead of time is always better prepared and more suited to life once its underway. Just ask all those nuts who live in their hilltop communities – the ones who’ve been stockpiling guns, ammo, food, water, diesel fuel and generators for decades. These guys will tell you that now is the time to stockpile for the coming apocalypse. But don’t mention zombies, they might think you’re crazy and shoot you.

But above all is the rather timid effort you put into stockpiling weapons, sir. I mean really, two handguns? Real survivalists have been spending the past few years amassing as many assault weapons, shotguns, pistols, and submachine guns as they can afford and the law will allow. Such popular weapons include the AR-15, Tech-9, Mossberg 590A1, and the Glock 17. And if the law is a bit inflexible in your state, just zip next door or go to a gun show!

zombiegun3Yes, it pains me to say it, buy you really dropped the ball on this one, sir! Now some might say that this was just your lame-ass attempt to excuse owning two illegal guns. But I know you to be a conscientious individual who cares greatly for your and your significant other’s safety. I also know that as such an individual, you want to be prepared to meet this inevitable catastrophe head on.

So assuming it hasn’t come to pass while you’re still in jail (in which case, you’ll die like a rat in a cage), I urge you to reconsider your efforts! Cover the necessities first, then worry about the incidentals. Thank you, and in the meantime, be sure to watch yourself while standing in the chow line. Also, don’t drop the soap. And if you can, find the biggest, meanest, ugliest man you can, and glom onto him. You don’t want to be just anybody’s bitch!

And if my might be so bold, you could read my Whiskey Delta series that deals with the zombie apocalypse, which I am currently working on the third installment for. It’s chock full of survival tips. They do get Amazon delivery in jail, don’t they? NOOOO? Well then, you’re screwed!

News from Space: Time Capsule to Mars

Time_capsule_to_mars1The selfie is an apparent obsession amongst today’s youth, snapping pictures of themselves and posting them to social media. But for just 99 cents, people can send a picture of themselves to the Red Planet as part of the Time Capsule to Mars (TC2M) – a student-led, crowdfunded project that aims to send three CubeSat microsatellites to the planet containing digital messages from tens of millions of people from all around around the world.

The objective of the TC2M – a project of Explore Mars – mission is to inspire people throughout the globe and allow them a personal connection with space exploration in the same spirit of the Apollo missions. The non-profit organization also aims to educate and inspire children by enabling them to upload their media content, track their spacecraft and lander, and participate in the mission via a personalized Mission Control portal over the internet.

Mars_exploreWith the help and support of NASA, MIT, Stanford University and Deep Space Industries (among others), the student-led team will design, launch, fly and land three CubeSat-based spacecraft on the surface of Mars. The projected cost of the mission, covering everything from design to launch, is $25 million, which TC2M will attempt to raise by way of crowdfunding.

In terms of sending media content, people currently have the option of uploading only images up to 10 MB in size. However, in the coming months, TC2M claims that participants will also be able to upload other types of media such as videos, audio clips and text files. In order to reach as many people as possible, uploads in the developing world will be free of charge for smaller files, underwritten by corporate sponsors.

Time_capsule_to_mars2Emily Briere, a mechanical engineering student who is heading the project, explained their aim thusly:

We hope to inspire and educate young people worldwide by enabling them to personally engage and be part of the mission. The distributed approach to funding and personal engagement will ultimately guarantee our success.

The data will be carried by three identical 13-kg (27-lb) CubeSat spacecraft, each 30 x 40 x 10 cm (12 x 16 x 4 inches) in size. This will be the first time that such spacecraft are used for interplanetary travel, as well as the first time that many of the new technologies are being tested. The data will be stored in a quartz crystal, which is extremely dense and could last for millions of years, hence making it ideal for surviving the hostile conditions on Mars.

Time_capsule_to_mars_thrusterThe technologies being tested on the three spacecraft include delay-tolerant networking for the Deep Space Internet, inflatable antennae, and new interplanetary radiation sensors that will pave the way for future human trips to Mars. But out of all the new technologies being tested, the most exciting is certainly the propulsion system. But the most interesting technology of all will be in the form of its engines.

The three spacecraft will be propelled by an ion electrospray system (iEPS), a microthruster developed at MIT that is essentially size of a penny (pictured above). Each spacecraft will be powered by 40 thruster pairs, which will generate thrust using an electric field to extract and accelerate ions. The ionic liquid propellant is much more efficient than rocket fuel, and MIT scientists believe a scaled-up version may one day bring humans to Mars.

Time_capsule_to_mars_thruster1The choice of employing three separate but identical spacecraft for the mission may be due in part to the fact that so many new technologies are being tested at the same time. To triple the chances of success, Briere has previously said that crowdfunders who want to send their media to Mars will have the option of having the data uploaded on all three spacecraft, for an additional price.

The spacecraft themselves will disintegrate as they traverse the Martian atmosphere. However, the payloads are being designed to aerobrake and land on the surface of Mars while keeping the data intact and preserved uncorrupted on the surface of the planet for a long, long time. As for how they intend to keep it stored until the day that manned missions can retrieve it, there are a few options on the table.

Time_capsule_to_marsOne option that is being considered is to use a microinscribed thin tungsten sheet, which has the advantage of being thin, light and strong, with a high melting point – meaning it won’t disintegrate upon entry – and good aerobraking properties because of its large surface area. However, there are concerns that sandstorms on Mars might damage the data once it has landed.

A second option would be an aerogel-shielded media. A metal ball could encase the data which would be stored in a very light medium, such as a quartz memory. The metal ball would be surrounded with an aerogel that will act as an ablative shield as it enters the atmosphere. And as it gets closer to the surface, the metal ball will act as a cushion for the data as it lands on Mars.

Time_capsule_to_mars3The organizers have only just announced their crowdfunding plans, and expect to reach the very ambitious goal of $25 million before the launch, which is planned for 2017. You can contribute to the mission and upload your own picture by visiting the mission website. And for those interested in possibly contributing, stay tuned to find out how and where you can donate once the crowdfunding campaign is up and running.

So in addition to showcasing new spacecraft, new media technologies, this project is also an attempt to stimulate interest in the new age of space exploration – an age characterized by public access and involvement. It’s also an opportunity to make your mark on the Red Planet, a mark which will someday (if all goes to plan) be uncovered by a new generation of explorers and settlers.

In the meantime, be sure to watch the short promotional video below which describes the mission and its goals:

News from Space: Mysterious Radio Waves Detected…

auriga_nebulaAccording to a story published on July 10 in The Astrophysical Journal, a radio burst was detected that may have originated outside of our galaxy. Apparently, these split-second radio bursts have heard before, but always with the same telescope – Parkes Observatory in Australia. Given that only this observatory was detecting these signals, there was debate about whether they were coming from inside our galaxy, or even from Earth itself.

However, this time the radio signals were detected by a different telescope – the Arecibo Observatory in Puerto Rico – which concluded that the bursts are coming from outside the galaxy. This is also the first time one of these bursts have been found in the northern hemisphere of the sky. Exactly what may be causing such radio bursts represents a major new enigma for astrophysicists.

Victoria Kaspi, an astrophysics researcher at McGill University who participated in the research, explained:

Our result is important because it eliminates any doubt that these radio bursts are truly of cosmic origin. The radio waves show every sign of having come from far outside our galaxy – a really exciting prospect.

arecibo_arrayFast radio bursts are a flurry of radio waves that last a few thousandths of a second, and at any given minute there are only seven of these in the sky on average, according to the Max Planck Institute for Radio Astronomy. Their cause is unknown, and the possibilities range from black holes, to neutron stars coming together, to the magnetic field of pulsars (a type of neutron star) flaring up.

The pulse was detected on Nov. 2, 2012, at the Arecibo Observatory – a National Science Foundation-sponsored facility that has the world’s largest and most sensitive radio telescope. While fast radio bursts last just a few thousandths of a second and have rarely been detected, the international team of scientists reporting the Arecibo finding estimate that these bursts occur roughly 10,000 times a day over the whole sky.

MaxPlanckIns_radiowavepulseThis astonishingly large number is inferred by calculating how much sky was observed, and for how long, in order to make the few detections that have so far been reported. Laura Spitler, a postdoctoral researcher at the Max Planck Institute for Radio Astronomy in Bonn, Germany and the lead author of the new paper, was also the first person to note the event. As she explained:

The brightness and duration of this event, and the inferred rate at which these bursts occur, are all consistent with the properties of the bursts previously detected by the Parkes telescope in Australia.

The bursts appear to be coming from beyond the Milky Way, based on measurement of an effect known as plasma dispersion. Pulses that travel through the cosmos are distinguished from man-made ones by the effect of interstellar electrons, which cause radio waves to travel more slowly at lower radio frequencies. The burst detected by the Arecibo telescope has three times the maximum dispersion measure that would be expected from a local source.

Four_antennas_ALMAEfforts are now under way to detect radio bursts using radio telescopes that can observe broad swaths of the sky to help identify them. Telescopes under construction in Australia and South Africa as well as the CHIME telescope in Canada have the potential to detect fast radio bursts. Astronomers say these and other new facilities could pave the way for many more discoveries and a better understanding of this mysterious cosmic phenomenon.

For those hoping this was a possible resolution to the Fermi Paradox – i.e. that the radio bursts might have been extra-terrestrial in origin – this news is a little disappointing. But in truth, its yet another example of the deeper mysteries of the universe at work. Much like our ongoing research into the world of elementary particles, every answer gives rise to new questions.

Supermoon as Seen From Around the World

supermoonThere was something special about this weekends full Moon, which you may have noticed if you were outside and not dealing with severe cloud cover. It was a July “Buck” Moon, or what is known as a Supermoon, when the Earth’s only satellite is at perigee – its closest point in its orbit to Earth – while its also full. And interestingly enough, it was the first of three Supermoons that is expected to happen this year.

As for myself, I was out walking in Esquimalt with my wife and her stepbrother, checking out his new pad and looking to see if there were any properties we might consider buying ourselves in the near future. As we walked, we caught sight of a rather bright and large moon hanging just above the city skyline. Not only was it full, it was a light brown color and appeared larger than at any time I had seen it in recent memory.

supermoon1As the evening went on, the Moon drifter higher into the night sky and grew smaller. It’s color also changed as it ascended, going from light brown to bright blue-white. But it’s brilliance was not diminished, and the wife and I walked home beneath a night sky that still seemed to possess some daylight. Needless to say, it was quite the magical evening, warm and mild and illuminated by an intensely bright Moon.

Technically speaking, a Supermoon is not radically different from a regular full Moon. But for people who outside this weekend and gazing at the horizon, the moon would have appeared rather large and light brown in color. And around the world, many people took notice and captured shots of the moon with their cameras and smartphones. And as usual, Universe Today was on hand to collect these images and compiled them into a Flickr Gallery.

supermoon2However, this month’s big full Moon was not the closest the terrestrial satellite will get to to Earth this year. The closest Full Moon of 2014 will occur next month on August 10th at 18:11 Universal Time (UT) or 1:44 PM EDT. On that date, the Moon reaches will reach perigee – or its closest approach to the Earth – at a distance of 356,896 kilometres at 17:44, less than an hour before it’s full.

Be sure to head on over their Flickr Gallery to see how the Moon appeared from different vantage points around the world. High in the sky, or low on the horizon, it was certainly an inspiring sight!

Fan-Made Film: Transformers “Attack on Giant”

https://i0.wp.com/onetechavenue.com/wp-content/uploads/2014/07/transformers-stop-motion.jpgMichael Bay has earned his fair share of notoriety for taking popular 80’s franchises and completely ruining them. With his crass remakes of nostalgic classics like Friday the 13th, A Nightmare on Elm Street, The Texas Chainsaw Massacre and a soon-to-be-reviled remake of Teenage Mutant Ninja Turtles, he might just best George Lucas for the title of who raped 80’s childhoods the most.

But it is arguably his work with the Transformers genre that has earned him the most scorn. From it’s beginning as a semi-decent movie that still had all the Bay staples (racist caricatures, sexist portrayals, stupid dialogue, action porn, eye-candy visuals), it quickly degenerated into a franchise that produced equal parts convulsive laughter and vomiting over just how bad it was. And with a fourth movie on the way, its clear he has no intention of stopping.

https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xpf1/t31.0-8/p417x417/10321100_703313716407853_1238366140818904261_o.jpgLuckily (as is often proving to be the case these days) fans of the franchise have stepped up to fill the void left by Bay’s hackish, opportunistic attempts to recreate a childhood classic. Entitled “Attack On Giant”, this mini-film was shot entirely in stop-motion using Transformer toys, sound effects from the original series, and focuses on a fight scene between two original version toys: Battle Tanker and Giant.

Sure, the visuals may not be as intensely colored as in Bay’s movies, and the stop-motion might be a little clunkier than seamless CGI, but the quality and the heart are there in spades. And you got to admit, this was a very fine effort for a fan-made film. This is just one of several stop motion fan films made by Harris Loureiro, a Malaysian amateur filmmaker who has created five Transformers fan-films to date.

Honest Trailers: Game of Thrones

https://i0.wp.com/p1cdn01.thewrap.com/images/2014/04/Honest-Trailer-Game-of-Thrones-618x400.jpgI’ve been spending entirely too much time over at Youtube lately. Have you seen those comments sections? If there was ever a reason for misanthropy, that would be it! But one can always find plenty of nuggets of awesomeness while navigating through that sea of virulence, and Honest Trailers is often the source. Below is the video for Game of Thrones they released a few months back to coincide with the release of Season Four.

!Warning! As it says in the intro, this video contains spoiler material for anyone who hasn’t viewed the first three seasons of GOT. But at this point, I got to assume that’s nobody, right? Or at least nobody who would care about this video. Anyway,  enjoy the video, and pay close attention to the inside joke at the end  (R+L=J, I can’t believe I got that reference. I am SUCH a nerd!)

The Future of Medicine: Muscle-Powered Pacemaker

piezoelectric-pacemakerOver the past few decades, cardiac pacemakers have improved to the point that they have become a commonplace medical implant that have helped improve or save the lives of millions around the world. Unfortunately, the battery technology that is used to power these devices has not kept pace. Every seven years they need to be replaced, a process which requires further surgery.

To address this problem, a group of researchers from Korea Advanced Institute of Science and Technology (KAIST) has developed a cardiac pacemaker that is powered by harnessing energy from the body’s own muscles. The research team, headed by Professor Keon Jae Lee of KAIST and Professor Boyoung Joung, M.D. at Severance Hospital of Yonsei University, has created a flexible piezoelectric nanogenerator can keep a pacemaker running almost indefinitely.

piezoelectric_nanogeneratorTo test the device, Lee, Joung and their research team implanted the pacemaker into a live rat and watched as it produced electrical energy using nothing but small body movements. Based on earlier experiments with piezoelectric generator technology used by KAIST to produce a low-cost, large area version, the team created their new high-performance flexible nanogenerator from a thin film semiconductor material.

In this case, lead magnesium niobate-lead titanate (PMN-PT) was used rather than the graphene oxide and carbon nanotubes of previous versions. As a result, the new device was able to harvest up to 8.2 V and 0.22 mA of electrical energy as a result of small flexing motions of the nanogenerator. This voltage was sufficient enough to stimulate the rat’s heart directly.

pacemaker3The direct benefit of this experimental technology could be in the production and use of self-powered flexible energy generators that could increase the life of cardiac pacemakers, reduce the risks associated with repeated surgeries to replace pacemaker batteries, and even provide a way to power other implanted medical monitoring devices. As Professor Keon Jae Lee explains:

For clinical purposes, the current achievement will benefit the development of self-powered cardiac pacemakers as well as prevent heart attacks via the real-time diagnosis of heart arrhythmia. In addition, the flexible piezoelectric nanogenerator could also be utilized as an electrical source for various implantable medical devices.

Other self-powering experimental technologies for cardiac pacemakers have sought to provide energy from the beating of the heart itself, or from external sources, such as in light-controlled non-viral optogenetics.But the KAIST pacemaker appears to be the first practical version to demonstrate real promise in living laboratory animals and, with any luck, human patients in the not-too-distant future.

Epic Rap Battles: Sir Isaac Newton vs. Bill Nye

erb_invbn1As a nerd and historian, I am obliged to share these latest Epic Rap Battles of History videos. First up, there’s Sir Isaac Newton Vs. Bill Nye. In addition to being funny, I think it set a record for most featured performers. These included Weird Al Yankovic in the role of Sir Isaac Newton and hip-hop artist Chali 2na in the role of Neil deGrasse Tyson, who jumps in at the fourth verse to give Bill Nye some much needed assistance.

Second, there’s the battle between revolutionaries George Washington vs. William Wallace. While this one didn’t feature anyone famous, it was some of Nice Peter and EpicLLOYD’s best work. And like all of their best videos, it is both educational and classically hilarious! Enjoy!
