Home, Home On The Range-R: Military-Grade Radar Scanners Can Help Police Spot You Through Walls

Big Brother isn't just watching - he's digging your moves, and he's not about to let something like legality or a concrete, windowless wall get in his way.  "Thanks" to Range-R radar technology, cops can sense motion inside a space without even having to kick down the doors.

According to USA Today, over the last two years, some 50 law enforcement agencies across America have adopted this technology, because search warrants take time and randomly breaking and entering sometimes gets bad press.  With no concern for privacy other than the privacy of the device itself (no notice of the technology nor its intents were released to the public), agencies from the FBI to the U.S. Marshalls to possibly your hometown cop-shop can now track you with the high-tech scanners.

When placed against an exterior wall, the radar use radio waves to penetrate up to 50 feet indoors and snitch if there's a person inside, where they are, and if they're mobile.  The devices are even sensitive enough to detect breathing, so basically, you have nowhere to hide.  They can "see" through concrete, dirt, adobe, wood, stucco or brick, and are even drone-mountable for you pesky apartment dwellers (or maybe just for the extra-lazy lawmen.)

While plausibly for use in hostage scenarios, firefighting emergencies, or search-and-rescue (according to the manufacturer's website), the Range-Rs have already been used over such inanity as parole jumping.  Originally invented for use in the wars in Iraq and Afghanistan, the devices, made by the L3 Communications company, cost $600 apiece.  Some $180,000 has been quietly spent on them since 2012.

While legal issues surrounding the use of the devices remain tricky, the Supreme Court specifically noted in a 2001 ruling that it was Constitutionally unsound to have police scan the exterior of a building with a thermal camera, and that the ruling would also apply to future radar systems.

"What?  We're just checking to make sure they're breathing...before we put a stop to that."

So far, this ruling has gone unrecognized, as police maintain they are using the devices for the usual "security concerns."  That tight security apparently precludes even mentioning that the Range-Rs exist.  William Sorukas, a former supervisor of the Marshals Service's domestic investigations arm, even went as far as to say, "If you disclose a technology or a method or a source, you're telling the bad guys along with everyone else."

Well, now the bad guys DO know.  And the good guys too.  Neither side should be happy about it.  What happened to doing police work to catch criminals, instead of stooping to their level and committing crimes to summarily execute "justice"?

Your security is just as important as national security.

Rock And Scroll: X-Rays Peer Into The Ancient World By "Reading" Volcanically-Charred Papyrus

When we ponder the implications of modern and future technology, it is interesting to note that while they drive us ever further forward, they can also help us understand history more thoroughly.  Such a case was just brought to light by an x-ray technician who creatively solved a classic problem by using an unexpected piece of modern technology.

According to the BBC, Dr. Vito Mocella, of the National Research Council's Institute for Microelectronics and Microsystems in Naples, Italy, was at a scientific conference in France when he learned that "X-ray phase-contrast tomography", a common medical analysis method, was being adapted for use in paleontology. He liked the idea and extrapolated it for another interesting historical cause: how to read data on volcanically-scorched ancient scrolls.

Phase contrast refers to the changing "phase" (slight distortion) of light waves as objects are X-rayed. The analysis of the contrast in the light provides a detailed 3D image of an object (as opposed to simply measuring the amount of light that is visible through the object, as is done with a conventional X-ray.) The technique is frequently used for mammograms, as it helps differentiate layers of an object when there is little contrast in the background material.

This allowed scientists to observe the difference between the ink and the papyrus of a scroll from the Herculaneum, an ancient library that was battered by the Mt. Vesuvius eruption in 79 AD. Volcanic gas at temperatures of 320 Celsius (608 Fahrenheit) charred the scrolls almost to the point of destruction, but ink remnants a mere tenth of a millimeter high were enough for the synchotron machine to deduce some of the words on the scroll.

Though the squashed papyrus fibers made determining letters with straight lines difficult (as they were harder to distinguish from the fibers themselves), letters with curved elements were identifiable. The scroll was written in Greek, which was the language of philosophy in ancient Rome. The team believes the scroll to be a work called "On Frank Criticism", a study advocating honesty between friends, written by the Epicurean philosopher Philodemus.

Dr. Mocella admits that while the innovative deciphering technique hasn't yet been perfected, he intends to continue experimenting with the project.  Mocella's team was quoted in National Geographic, saying, "This pioneering research opens up new prospects not only for the many papyri still unopened, but also for others that have not yet been discovered."

Ballroom Blitzar: Massive Space-Based Radio-Wave Bursts, But No Message...Yet

Like many fascinating things, sometimes a thing that exists only in legend surprises everyone and blasts into reality.  This is even more interesting when it's a scientific event.

According to Gizmodo, this week several massive bursts of energy emitted from deep space  were recorded by scientists at the Parkes Telescope in New South Wales, Australia.  The massive bursts of tightly-banded radio-frequency waves are known as "blitzars", although this is just one term for what could possibly be a variety of explanations for the observed phenomena.  Though blitzars only last a millisecond, they emit the same power as the sun would over an entire day.  So astronomically speaking, this is pretty striking.

Scientists first began identifying blitzars in 2007 thanks to documented astronomical observations.  Although the data was weeks or even years old, nine blitzars were noted to have occurred.  However, this week's observation happened in real time, and appeared to emanate from the constellation Aquarius.  Little more is known about its origins other than that the source "must be huge, cataclysmic and up to 5.5 billion light years away," according to researcher Emily Petroff.

Speculations on the source include flares or collapse from large, possibly magnetically-charged neutron stars, but these ideas are presently unfounded.  As Keith Bannister from Australia's national science agency told New Scientist, "Nobody knows what to make of it...All the ideas are very exotic so ruling them out is all you can do at the moment."

Scientists will continue watching the skies, including in other bandwidths, to see if there are any complimentary blitzar bursts elsewhere. This could help to quantify the density of interstellar mediums via observing the speed and dispersion of the signal through free electrons in space. So we'll perhaps learn how fast and far such energy can travel...even if we don't yet know what it means.

Could creatures at the source be listening to OUR radio waves?  And are they (rightly) disgusted by our terrible pop music?

Elon Musk's Martian Internet Might Help All Of Mankind

Elon Musk is rampaging into the future with yet another astronomically awesome plan.  The mastermind behind SpaceX, Tesla, and the Hyperloop doesn't just want folks to comfortably travel to space - he wants to make sure they're easily connected to the internet while they're up there.

It might sound crazy to think that the humans who will be among the first "space tourists" would spend their time googling cat videos and playing online poker, but Musk's plans are extra ambitious.  His intent is to establish a space internet so powerful that when colonizing Mars becomes a reality, the pioneers will be able to chat about it on Facebook.

Now THIS is an occupation that will achieve something!

According to Bloomberg Business Week, this new and improved World Wide Web would become the Galaxy Wide Web thanks to a fleet of low-flying satellites Musk intends to launch.  While it would not only aid future connectivity to space travelers, it would serve the immediate purpose of expanding internet speed and coverage all around our home planet.

“Our focus is on creating a global communications system that would be larger than anything that has been talked about to date,” Musk stated.

The first humans will be "checking in" on Mars sooner than we think.

The satellites would orbit some 750 miles above the earth, where the vacuum of space would facilitate faster flow of data - even more so than using fiber-optic cables on Earth.  With the speed of light operating a full 40% faster in the vacuum of space, bouncing data off of Musk's satellites and then back to earth would improve speeds considerably.

Great hypothesis...now, to test!

Musk is aware that his competitors have the bandwidth territory, but he holds the ace of rocket technology.  He intends to open a satellite factory in Seattle that will draw engineering talent of all sorts (SpaceX projects will also be in fabrication there), and has a long-term plan over the next five years to bring the initiative to fruition.  The exclusive opening of the Seattle SpaceX office took place on Friday, adding to an ever-increasing network of operational sites.  He is completely serious about looking even further than that, though.

“It will be important for Mars to have a global communications network as well,” he says. “I think this needs to be done, and I don’t see anyone else doing it...we see it as a long-term revenue source for SpaceX to be able to fund a city on Mars.”

In space, no one can hear you scream at Candy Crush.

Newsweek reported that Musk expounded on this statement, telling the assembled crowd at the launch of the Seattle SpaceX office that, “One day I will visit Mars.” He feels the goal of establishing humans on Mars could be feasible inside the next two decades. Most of all, it's for humanity's own good, or as Musk explains, “the thing that matters long term is to have a self sustaining city on Mars, to make life multi-planetary.”

So at least if you end up marooned on Mars, there'll be Netflix and Pandora there to entertain you.  And no one will fault you for not accepting their Facebook invites.

Space Station Sunday: More Than Just Chillin'

Good evening, space fans!  There was some drama (but thankfully a safe resolution) on the ISS this week, when an alarm roused the astronauts from sleep to indicate that an ammonia leak was possibly taking place.  Fortunately, this was not the case.

According to the New York Times, the alarm sounded not once but twice on Wednesday, when pressure had built up in a water coolant loop on the ISS.  Normally, the water keeps the space station cool by circulating in the loops and then transferring the heat to external ammonia loops, which then radiate excess heat into space.  Thusly cooled, the external ammonia loops keep the station chill from the outside, though due to ammonia's toxicity, it is not used to cool the station interior (hence the water loops.)  The overburdened loop signified that perhaps ammonia was leaking into the water coolant loop, which would put it in dangerous proximity to the air inside the station.

Even the smallest bits of space work need constant attention.

NASA spokeman Bob Jacobs summed it up calmly, stating that, "We saw an increase in water loop pressure, then later saw a cabin-pressure increase that could be indicative of an ammonia leak in the worst-case scenario...So we protected for the worst-case scenario and isolated the crew in the Russian segment of the space station while the teams are evaluating the situation."

Nonessential systems were temporarily shut down to prevent any kind of overheating on the station.  This included scientific freezers aboard, but no data was lost due to the fact that the freezers are designed to remain cold for eight hours, independent of power supply.  The power was restored well within the eight-hour window.

According to the deliciously in-depth technical account of event posted on nasaspaceflight.com, after the initial high-pressure/possible leak alarm went off, the astronauts followed procedure by donning their PBAs (Portable Breathing Apparatus), cutting off the IMV (Inter-Module Ventilation), and quarantining themselves in the RS (Russian section) by sealing the Node 1 Aft CBM hatch.  Atmospheric tests for ammonia were then conducted, all which fortunately proved negative.

Ready for anything:  NASA astronaut Terry Virts and ESA astronaut Samathan Cristoforetti practiced for problems on 12/1.

Ground teams then rerouted the problem areas and vented nitrogen to relieve the pressure.  The crew were cleared to reenter the US segment, but returned hours later when indications of rising cabin pressure once again manifested.  Once again, no ammonia leak was detected.  This second rise in pressure was likely due to the station rebooting itself after the power-down and use of emergency breathing devices.

NASA Spaceflight considered the event a good practice run, albeit a somewhat scare one.  They stated, "If nothing else, the incident served to exercise the well-practiced procedures, proving that both the crew and ground teams responded in a timely and appropriate manner to a situation that could have been very dangerous if missed – thus serving to prove the effectiveness of NASA’s vigorous regime of procedural training and simulation."

All good in the orbital hood.

The Russian space agency Roscosmos also agreed the scenario was handled well, with Maxim Matyushin, head of the Russian mission command center, telling the Independent UK that,  "Safety of the crew has been achieved through the coordinated and timely actions themselves cosmonauts and astronauts, as well as operational management groups in Moscow and Houston."

Despite the drama, fellow spaceman James Kelly (a Space Shuttle pilot who served two missions to the ISS) chimed in from mission control with some levity, enthusing, "Enjoy your impromptu day off."

 

Keeping it cool.

In other news, the SpaceX Dragon capsule that made it safely to the ISS last week caused no trouble...however the landing of its attendant Falcon 9 rocket was not so smooth.  This week, exclusive imagery of the rocket crash was released.  The original (and still tangible) intent from the SpaceX mission was to land the rocket safely on an offshore pad and have it retrofitted for re-use.  This plan didn't exactly work out, just yet.  Inappropriately exciting video (linked below) followed.

Well, that's why they call it experimenting.

Not bad, considering how few rockets, you know, LAND.

That's all this week from our outstanding orbital outpost!  Be sure to tune in next week for more awesomeness above the atmosphere...watch this space!

Solar Panels As Canal Covers? India Gathers Power, Saves Water, Solves Problems

The science of sustainable energy requires making more efficient means of storage and accessibility for your harvested power...but sometimes it can have bonus advantages, when properly plotted.  Unlike oil spills which contaminate massive swaths of ocean, or fracking which can cause a release of chemicals potent enough to set tap water afire, no one worries when there is a solar power leak (some people even pay for these raw materials...look at any tanning salon.)  Now, a community in India has made gathering solar energy an even more useful endeavor, thanks to positioning the solar panels over irrigation canals to thwart extra evaporation.

It's like the peanut butter and chocolate of conservation.
(Image courtesy earthtechling.com.)

According to Yahoo, in the Gujurat state of India, the booming business of solar power is setting precedents for the rest of the nation and likely the world.  By building solar panels over irrigation canals, communities are left not only with more free land space, but also contribute to the efficiency of their farming by not losing excess water to evaporation.  A plant in Vadodara which opened in October produces 10 MW of power thanks to 33,800 solar panels stretched across 3.6 km of irrigation canals (which it in turn powers the pumping distribution of.)  On a nice day, 50,000 electrical units (that's 50,000 hours of usage at 1,000 watts) are sent from the solar into the system.

While the canal-covering solar panels are more expensive to build,  they are easily accessed for cleaning and maintenance.  The water below will eventually tend to 4.45 million acres via some 75,000 km of canal throughout Gujurat and Rajasthan, known as the Sardar Sarovar project.  Already the Vadodara plant has made 16 hectares of land available, and is projected to conserve some 90 million liters of water per year.

The benefits add up:  the creation of the solar infrastructure also powers more jobs.

As Vice magazine notes, there are a number of dually-useful elements to the project beyond the evaporation containment, including the solar panel conduits being kept cooler thanks to the water below, and also the lack of squabbling over land issues (the canals were utilitarian elements already in place, and adding to them disrupts neither the local environment nor the populace.)

Overall, the Indian government plans to gather 100 MW of power from canal-top photovoltaic panels by 2017.  By 2022, the nation intends to have over 10% of its total energy created by solar power.  The effort is not lost on the rest of the world.  U.N. Secretary General Ban Ki-Moon recently visited and remarked, "I saw more than glittering panels – I saw the future of India and the future of our world...I saw India's bright creativity, ingenuity and cutting-edge technology."

Crafty conservation can help fuel the future in ways we haven't even yet pondered.  The fact that a major nation has stepped up to address the power problems in an efficient and intelligent way brings hope for the rest of the world.  Maybe soon we can stop shooting off mountaintops and drilling beneath oceans to gather our energy.  Let's start using our power - and our methods of power collection - for good.

Yet another plus:  all that water saved from evaporation could be made potable for poverty-stricken regions.  Win, India.

Power On The Fly: Pioneering With A Pocket-Sized Charger

Sure, you love your devices, but feeding them can become problematic at times.  Stop bothering the bartender and bust out your own portable power, thanks to a new invention: Kraftwerk.  Created by the German company eZelleron, the gadget runs on regular everyday lighter fuel to unobtrusively juice your phone, camera, tablets, e-readers, and whatever other bit of technology is near-permanently in your orbit.

According to the Daily Mail, the device never requires a plug-in of its own, and each refill of lighter fluid or camping gas is enough to fuel 11 iPhones.  The eZelleron company maintains that Kraftwerk is a "quantum leap in terms of performance and availability compared to conventional battery chargers...Kraftwerk really is a small portable power station."

This is your first step to escaping the Grid.
(Image courtesy www.dailymail.co.uk.)

Slated for release in November/December of this year, Kraftwerk already exists in fully functioning prototypes. The remainder of the project is being funded by Kickstarter. The device appeals to a sense of freedom and adventure, with their Kickstarter campaign noting that Kraftwerk is "an invaluable advantage both in everyday life and even when traveling to the ends of the earth."

The durability and portability are major advantages for our hyper-connected world. Lighter than carrying batteries, adept with connection (a simple USB port handles all), approved for air travel, and capable of enduring all sorts of weather conditions, this energy-efficient device will discreetly help fuel the future, 5 volts at a time.

Never miss a gnarly shot again...keep your camera juiced-up anywhere with Kraftwerk.

The folks behind Kraftwerk are pushing forth what is a small but important part of a larger picture. According to wikipedia, Germany has been hailed as "the world's first major renewable energy economy" and had a third of their electricity generated from sustainable resources in 2014.  With Germany poised to have nearly half of their electricity generated by sustainable resources by 2025, items like the Kraftwerk reflect how such an innovative mentality benefits people in many scenarios, not just on the macro scale.

Their kickstarter pitch isn't being hyperbolic when they say, "So let's revolutionize mobile energy supply together!  Be a pioneer on the fascinating road to freedom of power!"  And nothing says "pioneering" like posting a selfie from someplace definitely sans sockets.  Kraftwerk, keep it going!

Perhaps the band Kraftwerk can use the device Kraftwerk to power their Man Machine?  The possibilities are endless...
