World’s Largest Lithium Ion Battery Switched on in South Australia

The world’s largest lithium ion battery has begun providing electricity into the power grid in South Australia.  The project is a collaboration between the state government, American firm Tesla, and Neoen, a French energy company. 

Tesla boss Elon Musk, who was not in attendance at the switch-on, had boldly promised to build the battery in South Australia within 100 days – a pledge that has been fulfilled.  The 100-megawatt battery was officially activated Friday.  Musk has said it was three times more powerful than the world’s next biggest battery, and promised to deliver it for free had it not been built on schedule.

The South Australian state government hopes the project can prevent power outages because it can rapidly deploy electricity when it is most needed and reduce prices.

Last September, South Australia suffered a state-wide power outage when storms damaged the electricity network.

State premier Jay Weatherill believes the new battery will guarantee energy supplies.

“People were making fun of South Australia for its leadership in renewable energy and blaming it for the black-out,” said Weatherill. “That, of course, has now been debunked as a myth.  We now know that our leadership in renewable energy is not only leading the nation but leading the world, and we are more than happy to supply our beautiful renewable energy stored in a battery to help out the national electricity market.”

Located near Jamestown, about 200 kilometers north of Adelaide, the Tesla-built 100 megawatt lithium ion battery is connected to a wind farm run by French energy company Neoen.

The farm has 99 wind turbines and generates electricity that can be stored in the battery to serve 30,000 people for about an hour.  In a statement, the California-based firm said the project in South Australia showed “that a sustainable, effective energy solution is possible”.

Critics of the battery have said the technology’s potential has been exaggerated.

The bulk of Australia’s electricity is still generated by coal, and the nation is one of the world’s worst per capita emitters of greenhouses gases.

 

 

Los Angeles Set to Embark on a Smart City Experiment

From cellphones and cars, to televisions and refrigerators, more devices are being connected to the Internet.

This network of connected devices is call the “Internet of Things” (IoT). Los Angeles, the second largest city in the United States, is planning to use the prevalence of these IoT devices as a testing ground for becoming a city of the future.

“By putting computers in parking meters, you already have computers in your car, and you have computers in the street lights. The ability to connect them to the Internet of Things allows a better way for your car to know where parking spots are available, allows better for it to communicate when street lights should turn green to maximize traffic flow,” said Ted Ross, chief information officer for the city of Los Angeles.

WATCH: Los Angeles About to Embark on a Smart City Experiment

What is I3? 

Los Angeles is a part of a consortium called “I3” that includes the University of Southern California (USC) and tech companies. This partnership is developing and will soon test an Internet of Things system. It aims to connect sensors placed around the city with other connected devices to make L.A. a smart city.

It is an endeavor that will also rely on residents’ participation, said Raman Abrol of Tech Mahindra. It is one of the I3 tech companies and will provide a platform for an online marketplace called Community Action Platform for Engagement or CAPE.

“Communities can collaborate with businesses and cities and share data in a manner where privacy’s enforced,” Abrol said.

In the online marketplace, neighborhoods could be shopping for a cheaper source of renewable energy or water filtration system. Companies can then compete for their business.

CAPE is just one of the many elements in the I3 system that will make up the Internet of Things network in Los Angeles.

“The I3 is an Internet of Things integrator. Through I3, we’re (Los Angeles) working with the University of Southern California and vendor partners to aggregate the data and give us a better ability to make decisions, decisions to maximize traffic flow, decisions to help reduce crime, decisions to help improve business prosperity,” Ross said.

Privacy, security concerns

As connected devices become more ubiquitous and the flow of personal data increases, privacy and security concerns will be more scrutinized.

“I think that this is one piece of a huge emerging problem, of figuring out how we protect privacy and limit government power in an era of rapidly expanding information availability and rapidly expanding data processing abilities. So it’s not just that there are more and more data points that are available for the government to look at. It is also that we are rapidly expanding our ability to analyze data,” said Stanford University Law School professor, David Alan Sklansky.

Sklansky has been closely following a U.S. Supreme Court case, Carpenter v. the United States, which examines whether police need a warrant to obtain cellphone location information. Sklansky said the decision from the case will impact other applications of technology and data in the modern age.

“The more powerful the technology, the more powerful the unintended consequences,” said Yannis Yortsos, dean of the USC Viterbi School of Engineering.

“How do you make sure to possibly regulate this because there has to be regulation so that they have legal and ethical issues taken into consideration as well,” Yortsos added.

Choose to connect

In Los Angeles, people will largely choose whether they want to provide data to the city.

“For someone who’s going to be able to let’s say, connect through their smart phone or through their vehicle, it’s extremely important that they agree and they consent to such matters,” Ross said.

While there was an initial forecast of a big demand in the Internet of Things, over time, the demand dropped, said Jerry Power, executive director of the USC Institute for Communication Technology Management.

“So we started looking at it and trying to understand why and what the problems were,” he said. “We looked at it from a perspective of privacy from the users’ standpoint. We realized privacy was an important issue. We realized that trust was an important issue, and we realized that incentives (was) an issue in the process as well.” 

Power continued, “what incentive has to go back to the users to get them to opt-in? The level of incentive depends on how much the user of the data, who wants the data, how much they disclose about what they’re going to do with the information and how well-trusted that person is.” 

“The exchange of data.” Power added, “if you think about it, it almost becomes like a form of currency, and it’s part of a transaction.”

The smart city experiment will begin at the University of Southern California and expand to the city of Los Angeles.

Some of what works from the program will be be made available for other cities to use.

Virtual Reality Allows Patients to Preview Their Own Surgery

Most of us would be shocked and afraid if a doctor told us we needed brain surgery. But imagine how much calmer you’d be if you could get inside your skull to navigate the path the surgeon will take? Technology can now make that happen. VOA’s Carolyn Presutti takes us to the Stanford Medical Center in Silicon Valley to see how virtual reality can get patients into their own heads.

Facebook Suspends Ability to Target Ads by Excluding Racial Groups

Facebook Inc. said on Wednesday it was temporarily disabling the ability of advertisers on its social network to exclude racial groups from the intended audience of ads while it studies how the feature could be used to discriminate.

Facebook’s chief operating officer, Sheryl Sandberg, told African-American U.S. lawmakers in a letter that the company was determined to do better after a news report said Facebook had failed to block discriminatory ads.

The U.S.-based news organization ProPublica reported last week that, as part of an investigation, it had purchased discriminatory housing ads on Facebook and slipped them past the company’s review process, despite claims by Facebook months earlier that it was able to detect and block such ads.

“Until we can better ensure that our tools will not be used inappropriately, we are disabling the option that permits advertisers to exclude multicultural affinity segments from the audience for their ads,” Sandberg wrote in the letter to the Congressional Black Caucus, according to a copy posted online by ProPublica.

It is unlawful under U.S. law to publish certain types of ads if they indicate a preference based on race, religion, sex or certain classifications.

Facebook, the world’s largest social network with 2.1 billion users and $36 billion in annual revenue, has been on the defensive for its advertising practices.

In September, it disclosed the existence of Russia-linked ads that ran during the 2016 U.S. election campaign. The same month it turned off a tool, also reported by ProPublica, that had inadvertently let advertisers target based on people’s self-reported jobs, even if the job was “Jew hater.”

Sandberg said in the letter that advertisers who use Facebook’s targeting options to include certain races for ads about housing, employment or credit will have to certify to Facebook that they are complying with Facebook’s anti-discrimination policy and with applicable law.

Sandberg defended race- and culture-based marketing in general, saying it was a common and legitimate practice in the ad industry to try to reach specific communities.

U.S. Representative Robin Kelly of Illinois, a member of the Congressional Black Caucus, said Facebook’s action was appropriate.

“When I first raised this issue with Facebook, I was disappointed,” Kelly, a Democrat, said in a statement. “When it became necessary to raise the issue again, I was irritated. Thankfully, we’ve been able to establish a constructive pipeline of communication that’s resulted in a positive step forward.”

Cloud Clothing Packs Computing Power Under Your Shirt

For individuals, storing information in the cloud means it can be available to them anywhere they have a connection to the internet. It can be cheap, and it can be useful, but because all that data is going back and forth, it’s not quite as secure as storing everything on your phone or home computer. But what if you could wear your information? That’s the idea behind some National Science Foundation-supported research into cloud clothing. VOA’s Kevin Enochs reports.

Snapchat Seeks to Attract More Users by Redesigning App

Snapchat is separating what friends share and what media organizations publish in an attempt to appeal to a broader range of users.

The photo messaging app has not been gaining enough users, especially beyond its core of younger people. Parent company Snap Inc.’s stock is down sharply since its initial public offering earlier this year.

Users will now see two separate feeds — one from friends and one from publishers and non-friend accounts they follow. Before, Snapchat was mixing those posts, much the way Twitter, Facebook and other rivals continue to do. Snap hinted at changes three weeks ago, but didn’t provide details then.

CEO Evan Spiegel took a jab at rivals, writing that social media “fueled ‘fake news’” because of this content mixing.

 

US Supreme Court Considers Limits on Government in Key Privacy Case

The U.S. Supreme Court signaled Wednesday it may be open to new limits on the government’s ability to track someone’s movements by accessing data on that person’s cellphone.

A case before the high court could result in a landmark decision in the ongoing debate over civil liberties protections in an era of rapid technological change.

At issue is whether law enforcement will be able to access cellphone data that can reveal a person’s whereabouts without having to first obtain a court-issued search warrant.

The case stems from the conviction of Timothy Carpenter for a series of robberies back in 2010 and 2011. Prosecutors were able to obtain cellphone records that indicated his location over a period of months, information that proved crucial to his conviction.

Get a warrant

On Wednesday, lawyers for the American Civil Liberties Union argued that law enforcement should be required to obtain a court-ordered search warrant before obtaining such information.

They also argued that allowing law enforcement to access the cellphone data without a warrant would violate the prohibition on unreasonable search and seizures contained in the Fourth Amendment to the U.S. Constitution.

“It is impossible to go about our daily lives without leaving a trail of digital breadcrumbs that reveal where we have been over time, what we have done, who we spent time with,” said ACLU attorney Nathan Freed Wessler, who spoke to reporters outside the Supreme Court following oral arguments. “It is time for the court, we think, to update Fourth Amendment doctrine to provide reasonable protections today.”

Some of the justices also raised concerns about privacy in the digital age.

“Most Americans, I think, still want to avoid Big Brother,” Justice Sonia Sotomayor, who often sides with the liberal wing of the court, said.

Chief Justice John Roberts, who often sides with conservatives on the court, said the central question was whether the cellphone information should be accessible to the government “without a warrant.”

Privacy versus security

Justice Department lawyers defended the process of obtaining the data without a court warrant, arguing that even though the technology has changed, the need to rapidly obtain such information for law enforcement has not. The government also argued that privacy rights are not at issue because law enforcement agencies can obtain information from telecommunications companies that record transactions with their customers.

Justices Samuel Alito and Anthony Kennedy indicated they were open to the government’s position in the case.

Legal experts say whichever way the court eventually rules could have an enormous impact on privacy rights in the digital age.

“I don’t think that this is a world that anybody anticipated a couple of decades ago,” Stanford University law professor David Alan Sklansky said via Skype. “These new data capabilities are rapidly increasing the things that government can do for good and for evil. And figuring out how we allow the government to make full use of these new capabilities, without endangering political liberties and endangering the privacy that is necessary for us to have the kind of flourishing democratic social life we want, is a huge ongoing challenge.”

Sklansky added that the United States “has historically been a leader in thinking about privacy rights, particularly with regard to privacy from the government.”

And he predicted that other countries will be closely following the high court case as they wrestle with similar conflicts. “This is a global problem. Countries around the world are trying to figure out how to deal with it. I think that people in all democratic countries should care about how the United States winds up resolving this question,” he said.

Past rulings

Twice in recent years the Supreme Court has ruled in major cases related to privacy and technology and both times ruled against law enforcement.

The court ruled in 2012 that a warrant is required to place a GPS tracking device on a vehicle. And in 2014, the high court ruled that a warrant is required to search a cellphone seized during an arrest.

A decision in the current case, known as Carpenter v. U.S., is expected sometime before the end of June.

Things You Might Not Know About Bubbly Bitcoin

Bitcoin blasted past $11,000 to hit a record high for the sixth day in a row on Wednesday after gaining more than $1,000 in just 12 hours, stoking concerns that a rapidly swelling bubble could be set to burst in spectacular

fashion.

Here are some facts that you might not know about the largest and best-known cryptocurrency.

HOW MANY ARE THERE?

Bitcoin’s supply is limited to 21 million — a number that is expected to be reached around the year 2140. So far, around 16.7 million bitcoins have been released into the system, with 12.5 new ones released roughly every 10 minutes via a process called “mining,” in which a global network of computers competes to solve complex algorithms in reward for the new bitcoins.

ENERGY DRAIN

These mining computers require a vast amount of energy to run. A recent estimate by tech news site Motherboard put the energy cost of a single bitcoin transaction at 215 kilowatt-hours, assuming that there are around 300,000 bitcoin transactions per day. That’s almost enough energy as the average American household consumes in a whole week.

BITS OF BITCOIN

Bitcoin’s smallest unit is a Satoshi, named after the elusive creator of the cryptocurrency, Satoshi Nakamoto. One Satoshi is one hundred-millionth of a bitcoin, making it worth around $0.0001 at current exchange rates.

BITCOIN BILLIONAIRES

Bitcoin has performed better than every central-bank-issued currency in every year since 2011 except for 2014, when it performed worse than any traditional currency. So far in 2017, it is up around 1000 percent. If you had bought $1,000 of bitcoin at the start of 2013 and had never sold any of it, you

would now be sitting on $80 million. Many people consider bitcoin to be more of a speculative instrument than a currency, because of its volatility, increasingly high transaction fees, and the fact that relatively few merchants accept it.

EXCHANGE HEISTS

More than 980,000 bitcoins have been stolen from exchanges, either by hackers or insiders. That’s a total of more than $10 billion at current exchange rates. Few have been recovered.

MYSTERY CREATOR

Despite many attempts to find the creator of bitcoin, and a number of claims, we still do not know who Satoshi Nakamoto is, or was. Australian computer scientist and entrepreneur Craig Wright convinced some prominent members of the bitcoin community that he was Nakamoto in May 2016, but he then refused to provide the evidence that most of the community said was necessary. It is not clear whether Satoshi Nakamoto, assumed to be a pseudonym, was a name used by a group of developers or by one individual. Nor is it clear that Nakamoto is still alive — the late computer scientist Hal Finney’s name is sometimes put forward. Developer Nick Szabo has denied claims that he is Nakamoto, as has tech entrepreneur Elon Musk more recently.

INFLATED CHINESE TRADING

Until earlier this year, it was thought that Chinese exchanges accounted for around 90 percent of trading volume. But it has become clear that some exchanges inflated their volumes through so-called wash trades, repeatedly trading nominal amounts of bitcoin back and forth between accounts. Since the Chinese authorities imposed transaction fees, Chinese trading volumes have fallen sharply, and now represent less than 20 percent, according to data from website Bitcoinity.

“MARKET CAP”

The total value of all bitcoins released into the system so far has now reached as high as $190 billion. That makes its total value — sometimes dubbed its “market cap” — greater than that of Disney, and bigger than the market cap of BlackRock and Goldman Sachs combined.

CRYPTO-RIVALS

Bitcoin is far from the only cryptocurrency. There are now well over 1,000 rivals, according to trade website Coinmarketcap. 

“SHORTING”

It is already possible to short bitcoin on a number of retail platforms and exchanges, via contracts for difference (CFDs), leveraged-up margin trading or by borrowing bitcoin from exchanges without leverage. But a number of big financial institutions — including CME Group, CBOE and Nasdaq — have

recently announced that they will offer bitcoin futures, which will open up the possibility of shorting the cryptocurrency to the mainstream professional investment universe.

Facebook Reports Progress in Removing Extremist Content

Facebook said on Wednesday that it was removing 99 percent of content related to militant groups Islamic State and al-Qaida before being told of it, as it prepared for a meeting with European authorities on tackling extremist content online.

Eighty-three percent of “terror content” is removed within one hour of being uploaded, Monika Bickert, head of global policy management, and Brian Fishman, head of counterterrorism policy at Facebook, wrote in a blog post.

The world’s largest social media network, with 2.1 billion users, has faced pressure both in the United States and Europe to tackle extremist content on its platform more effectively.

In June, Facebook said it had ramped up use of artificial intelligence, such as image matching and language understanding, to identify and remove content quickly.

“It is still early, but the results are promising, and we are hopeful that AI (artificial intelligence) will become a more important tool in the arsenal of protection and safety on the internet and on Facebook,” Bickert and Fishman wrote.

“Today, 99 percent of the ISIS and al Qaeda-related terror content we remove from Facebook is content we detect before anyone in our community has flagged it to us, and in some cases, before it goes live on the site.”

ISIS is an acronym for Islamic State.

The blog post comes a week before Facebook and other social media companies such as Alphabet’s Google and Twitter meet with European Union governments and the EU executive to discuss how to remove extremist content and hate speech online.

“Deploying AI for counterterrorism is not as simple as flipping a switch. … A system designed to find content from one terrorist group may not work for another because of language and stylistic differences in their propaganda,” Facebook said.

The European Commission in September told social media firms to find ways to remove the content faster, including through automatic detection technologies, or face possible legislation forcing them to do so.

Artificial Muscles Give ‘Superpower’ to Robots

Inspired by the folding technique of origami, U.S. researchers said Monday they have crafted cheap, artificial muscles for robots that give them the power to lift up to 1,000 times their own weight.

The advance offers a leap forward in the field of soft robotics, which is fast replacing an older generation of robots that were jerky and rigid in their movements, researchers say.

“It’s like giving these robots superpowers,” said senior author Daniela Rus, professor of electrical engineering and computer science at the Massachusetts Institute of Technology (MIT).

The muscles, known as actuators, are built on a framework of metal coils or plastic sheets, and each muscle costs around $1 to make, said the report in the Proceedings of the National Academy of Sciences, a peer-reviewed U.S. journal.

Their origami inspiration derives from a zig-zag structure that some of the muscles employ, allowing them to contract and expand as commanded, using vacuum-powered air or water pressure.

“The skeleton can be a spring, an origami-like folded structure, or any solid structure with hinged or elastic voids,” said the report.

Possible uses include expandable space habitats on Mars, miniature surgical devices, wearable robotic exoskeletons, deep-sea exploration devices or even transformable architecture.

“Artificial muscle-like actuators are one of the most important grand challenges in all of engineering,” said co-author Rob Wood, professor of engineering and applied sciences at Harvard University.

“Now that we have created actuators with properties similar to natural muscle, we can imagine building almost any robot for almost any task.”

Researchers built dozens of muscles, using metal springs, packing foam or plastic in a range of shapes and sizes.

They created “muscles that can contract down to 10 percent of their original size, lift a delicate flower off the ground, and twist into a coil, all simply by sucking the air out of them,” said the report.

The artificial muscles “can generate about six times more force per unit area than mammalian skeletal muscle can, and are also incredibly lightweight,” it added.

A .09-ounce (2.6-gram) muscle can lift an object weighing 6.6 pounds (three kilograms) “which is the equivalent of a mallard duck lifting a car.”

According to co-author Daniel Vogt, research engineer at the Wyss Institute, the vacuum-based muscles “have a lower risk of rupture, failure, and damage, and they don’t expand when they’re operating, so you can integrate them into closer-fitting robots on the human body.”

The research was funded by the Defense Advanced Research Projects Agency (DARPA), the National Science Foundation and the Wyss Institute for Biologically Inspired Engineering.

India’s Global Entrepreneurial Summit to Focus on Women

Startup founders, investors and tech leaders from around the world are heading to Hyderabad, India for the 8th annual Global Entrepreneurship Summit, co-hosted by the U.S. and Indian governments.

Ivanka Trump, adviser to U.S. President Donald Trump and his daughter, will join host Prime Minister Narendra Modi in kicking off the three-day event, which will focus on women in business. More than 1,500 participants from 150 countries are expected at the event, which runs from November 28 through 30.

 

It had not been clear whether the Trump administration would continue the annual summit that was launched at the White House by the Obama administration in 2010. Trump has focused on domestic growth and U.S. job creation with an “America first” message.

But in June, Prime Minister Modi, while visiting the White House, announced that the two countries would co-host the summit.

 

America first, global partners

 

The gathering comes as the U.S. and India appear to be working to strengthen ties.

 

Having an “America first” economic policy is “not exclusive of collaboration, partnership and strong economic security and social relationships around the world,” said a senior administration official, speaking anonymously.

 

The summit is “a testament to the strong friendship between our two people and the growing economic and security partnership between our two nations,” said Ivanka Trump during a news conference this week.

Participants at this year’s summit will represent four industry sectors — energy and infrastructure, health care and life sciences, financial technology and digital economy, and media and entertainment.

 

Women in majority

 

In a first for the event, women will represent 52 percent of the attendees. Ten countries, including Afghanistan and Saudi Arabia, are sending all female delegations.

 

In advance of the summit, the Indian state of Telangana, where Hyderabad is located, has been working to clean up the city, and there have been reports of beggars being relocated.

“We know that the Indian government is really firmly committed to raising individuals out of poverty and to create economic opportunity for its large and diverse population and we think they are making great progress,” said another U.S. official.

Mobile App Connects Responders to Those Having Mental Health Crisis

Rickey pushes himself up slowly, grabs the leash tethered to the side of his walker and takes a few steps. His dog, a terrier named Madman, perks his ears up and follows him. Rickey pauses and looks across the street at a rundown building.

“That was a Blues Club,” he says. “The police station was a jazz club. Miles Davis, John Coltrane, we had all them,” says the 69-year-old. 

But the far-off look in his eyes isn’t reality. The nightlife that once electrified the Tenderloin District of San Francisco is no more.

Illicit drugs are dealt openly on the streets of the Tenderloin, a neighborhood in San Francisco, California. The Tenderloin has become a corrupt, high-crime neighborhood with homeless people lining the sidewalks.

High crime rates

The Tenderloin Housing Clinic and San Francisco police statistics show violent crime in just one block of the Tenderloin “is 35 times higher than the rest of the city.” In addition, one aggravated assault occurs every day and robbery statistics are even higher.

But several years ago, trendy businesses priced out of an adjacent area, brought property in Tenderloin. The gentrification of the area is starting, but it’s created another problem. More homeless filter onto the streets as real estate gets more expensive.

“Oh, hey, there you are.” A guy wearing black-rimmed glasses and a deep purple T-shirt and purple vest greets Rickey.

Jacob Savage is a community activist who founded the group Concrn.

Savage, who describes himself as a “privileged white guy,” found common ground with Rickey — and other Tenderloin residents — by playing a trumpet. He’s never without the instrument.

The two men — who couldn’t look more different — harmonize together in a duet. Rickey’s fingers snap to the beat of Savage’s horn, then he starts belting out, “Stand by Me,” a popular ballad by Ben E. King. It’s a calm, fun moment in Savage’s otherwise serious day.

Building trust

As a 15-year-old growing up in wealthy, tech-savvy Palo Alto, California, Savage became a police cadet, and spent six years riding along on calls. But he says the criminal arrests and prison sentences didn’t satisfy his passion to help others.

A few years ago, Savage brought Concrn to the Tenderloin, through a mobile app and a team of responders.

Through the app, witnesses report incidents of mental crises with descriptions of the person, location and other notes.

“When you submit that,” says Savage, “it goes into our dispatching platform” where responders are assigned to the incident. 

They arrive on the scene and offer mental health or drug abuse assistance before police arrive to make arrests. Often that first meeting includes only a conversation if the Tenderloin resident refuses treatment. Savage is fine with that.

“It’s building trust and having a trusting relationship so when they are actually ready to get better, we’re there,” he says.

Each Concrn responder completes 20 hours of classroom instruction and 80 hours on the street. Fifty people have completed the training.

In the past few years, they’ve responded to 2,000 crises. The ultimate goal is to train residents as responders, so the community is self-sufficient and doesn’t need Concrn. But that intention is years away.

Carrying a trumpet

Savage gets a call for a crisis several blocks away and he walks there with his trumpet at his side.

When he arrives, police are still there, but no disturbance. He approaches some men and mentions Concrn.”What kind of music do you play?”they ask. He starts a jazz number and they smile. 

Then a police officer taps Savage on his shoulder. There’s a guy police can’t handle right now – could he see what he can do?

Savage walks over to a thin young man dressed in black wearing a magenta scarf around his head. He’s bopping and weaving and talking to no one in particular. Jacob interrupts the constant gibberish.”Hey brother, what’s your name buddy?”

“Eddie” is the only word Jacob can understand in the restless man’s ongoing monologue.

Savage thinks he’s on crystal meth and asks if him if he would like to go to a clinic.

Eddie keeps blabbering but doesn’t answer. Savage sees the cigarette lighter he’s holding and asks if he would like a cigarette. Savage contacts another Concrn responder and starts playing his trumpet as a beacon.

Savage explains, “Cigarettes are a last resort to use when people are going so fast we can’t understand them or they are panicking.”

David, the other responder, finds their location from the trumpet blast and hands Eddie the cigarette, which he half eats. 

Savage and David spend several hours with Eddie. They learn he’s a composer.

Eddie offers to sell Savage his black leather outfit. They part, hoping to meet on the street again. Maybe by then Eddie will be ready to accept Concrn’s intervention.

Rwanda Ramps up STEM Education for Girls

In Rwanda, the number of schoolgirls studying science, technology, engineering and mathematics, the so-called STEM fields, is climbing steadily. It’s part of an ambitious government agenda to transform the economy. In the past decade, several STEM schools for girls have opened in Rwanda amid the rising demand.

Does Cellphone-Sweeping ‘StingRay’ Technology Go Too Far?

New York City, Los Angeles, Chicago and Las Vegas are among scores of police departments across the country quietly using a highly secretive technology developed for the military that can track the whereabouts of suspects by using the signals constantly emitted by their cellphones.

Civil liberties and privacy groups are increasingly raising objections to the suitcase-sized devices known as StingRays or cell site simulators that can sweep up cellphone data from an entire neighborhood by mimicking cell towers. Police can determine the location of a phone without the user even making a call or sending a text message. Some versions of the technology can even intercept texts and calls, or pull information stored on the phones.

Part of the problem, privacy experts say, is the devices can also collect data from anyone within a small radius of the person being tracked. And law enforcement goes to great lengths to conceal usage, in some cases, offering plea deals rather than divulging details on the StingRay.

“We can’t even tell how frequently they’re being used,” said attorney Jerome Greco, of the Legal Aid Society, which recently succeeded in blocking evidence collected with the device in a New York City murder case. “It makes it very difficult.”

At least 72 state and local law enforcement departments in 24 states plus 13 federal agencies use the devices, but further details are hard to come by because the departments that use them must take the unusual step of signing nondisclosure agreements overseen by the FBI.

An FBI spokeswoman said the agreements, which often involve the Harris Corporation, a defense contractor that makes the devices, are intended to prevent the release of sensitive law enforcement information to the general public. But the agreements don’t prevent an officer from telling prosecutors the technology was used in a case.

In New York, use of the technology was virtually unknown to the public until last year when the New York Civil Liberties Union forced the disclosure of records showing the NYPD used the devices more than 1,000 times since 2008. That included cases in which the technology helped catch suspects in kidnappings, rapes, robberies, assaults and murders. It has even helped find missing people.

But privacy experts say such gains come at too high a cost.

“We have a Fourth Amendment to the Constitution,” said Jennifer Lynch, an attorney with the Electronic Frontier Foundation, referring to the protection against unreasonable search and seizure. “Our Founding Fathers decided when they wrote the Bill of Rights there had to be limits placed on government.”

Lawmakers in several states have introduced proposals ranging from warrant requirements to an outright ban on the technology; about a dozen states already have laws requiring warrants. Federal law enforcement said last year that it would be routinely required to get a search warrant before using the technology – a first effort to create a uniform legal standard for federal authorities.

And case law is slowly building. Two months ago, a Washington, D.C., appeals court overturned a conviction on a sex assault after judges ruled a violation of the Fourth Amendment because of evidence improperly collected from the simulator without a proper warrant.

In the New York murder case argued by the Legal Aid Society, a judge in Brooklyn last month ruled that the NYPD must have an eavesdropping warrant signed by a judge to use the device, a much higher bar than the “reasonable suspicion” standard that had previously been required.

“By its very nature, then, the use of a cell site simulator intrudes upon an individual’s reasonable expectation of privacy, acting as an instrument of eavesdropping and requires a separate warrant supported by probable cause,” wrote state Supreme Court Judge Martin Murphy.

New York City police officials disagreed with the ruling and disputed that a StingRay was even used in the case, even though there had been a court order to do so. Police officials also said they have since started requiring a higher stander of probable cause when applying for the devices.

Legal Aid Society’s Greco said he hoped the ruling will push the nation’s largest department into meeting the higher standard, and help judges better understand the intricacies of more cutting-edge surveillance.

“We’re hoping we can use this decision among other decisions being made across the country to show that this logic is right,” Greco said. “Part of an issue we’re facing with technology, the judges don’t understand it. It makes it easier if another judge has sat down and really thought about it.”

For Cambodian Techies, US Tour Ends With Vision of Startup at Home

At home in Phnom Penh, the five techies knew of each other by reputation but had never met. After three weeks touring the United States, they’ve returned to Cambodia fired up about collaborating on a fintech startup.

“Before, when I thought about a million-dollar business, it was only a dream,” Sopheakmonkol Sok, 29, a co-founder and CEO of Codingate, a web and mobile developer, told VOA Khmer.

Langda Chea, founder and CEO of BookMeBus, a booking app for Cambodian bus, ferry and taxi travel, met Sopheakmonkol Sok while under the auspices of a U.S. State Department program called the International Visitor Leadership Program (IVLP), which includes work on democracy, human rights, security, environment, international crime, economic growth and development.

​Learned from other companies’ successes

The tech intensive “Accelerating Tech Entrepreneurship and SME Development” focused on small- and medium-sized enterprise growth in the tech sector. The Cambodians engaged with tech leaders in Washington, D.C.; Cleveland, Ohio; Raleigh, North Carolina; San Francisco and San Jose, California.

In Silicon Valley, they met with “a lot of successful companies, big and small,” Sok said. “So we saw how they operate and manage their businesses, and we learned from their success.” 

Nicholas Geisinger, the IVLP program officer who oversaw the tech trip, said the program works when it encourages the cross-pollination of ideas among the exchange visitors and Americans.

“We [told] them about the development in our country,” Chea said, listing positives such as a fast, inexpensive internet infrastructure, an improving business environment, and the growth of an educated workforce “that show potential because it’s an advantage for us if they invest in Cambodia.” 

“Ideas were originated with the U.S. embassy … and furthering economic development in Cambodia was one of their objectives. … That’s why we did a program on this topic,” Geisinger said. 

It’s a bonus when the visitors learn “and have new ideas by talking with each other in this new environment,” Geisinger said. “That’s a huge win for the program, a win for the people of Cambodia and I can’t wait to see what they will do next.” 

Chankiriroth Sim, founder and CEO of BanhJi, a fintech startup, told VOA Khmer that while the participants learned more about the U.S. tech scene on their tour, the “important thing is that we got to know each other better.” 

Or as Rithy Thul, the founder of Smallworld, a collaborative co-working space, told VOA Khmer, the five learned “we can work together when we are back” in Cambodia.

Or can they? Each one has a tech business, so who will run their fintech collaboration, the details of which they’re not disclosing, other than to say it is in the payment space. That remains under discussion.

“The advantage is that, when we succeed, it can help Cambodia, it helps the next generation,” BookMeBus founder Chea said. “But I’m worried that if there are too many smart people in one group, it could be a disadvantage.” 

Opportunity and support

After three weeks, Chea said he was impressed with how various levels of government in the U.S. — local, state and federal — support startups.

“The opportunities I see, including the cooperation between the government, the enterprises, and the incubation, which helps small business to understand its own business, to make it standardized in order to raise fund(s) or find investors,” Chea said.

For example, the Cambodians and local tech types discussed how local firms and city government can support each other at the San Francisco Mayor’s Office of Civic Innovation (MOCI).

It is the only operation of its kind in the U.S., said Siobhan Oat-Judge, a Pearson fellow in the department that “connects government agencies with startups to develop technology products that address civic challenges,” according to the MOCI website.

Helping startups to grow isn’t a one-way street, “the community as a whole gains from helping them since they bring solutions to problem. … It’s mutually beneficial,” Oat-Judge said.

“We are supporting startups, but we are also gaining from them because they are bringing in solutions for problems,” she added. “They are bringing new ideas, new technology that are helping us to improve the way we are doing things.”

Funding issues

It’s more difficult to obtain funding in Cambodia than it is in the U.S., said Visal In, co-founder of KhmerLoad, the first Cambodian tech startup backed by Silicon Valley investors.

For starters, there’s more U.S. money seeking potentially profitable ideas, something that In found when 500 Startups, a global venture capital based in San Francisco, invested $200,000 in his site.

“Some companies outside Cambodia totally depend on getting grants, and in Cambodia it would be difficult if we did that,” In said. For other companies outside Cambodia, “they can sustain themselves without profit, but because they have a good idea, they can be seeking outside funding for five or six years, the time it takes to become profitable. In Cambodia, that’s impossible.”

Kounila Keo, one of two female IVLP participants, said she would like to see the Cambodian government step up its support for startups.

Keo, a managing director at RedHill Asia and who was spotlighted by Forbes 30 under 30 Asia in 2017, said, “What I want to have in Cambodia in the future is a better and closer cooperation between the government and private companies in order to enhance the tech startup and tech entrepreneurship initiatives.”

In Fukushima Cleanup, It’s Human Nature vs. Science

More than six years after a tsunami overwhelmed the Fukushima nuclear power plant, Japan has yet to reach consensus on what to do with a million tons of radioactive water, stored on site in around 900 large and densely packed tanks that could spill should another major earthquake or tsunami strike.

The stalemate is rooted in a fundamental conflict between science and human nature.

Experts advising the government have urged a gradual release into the Pacific Ocean. Treatment has removed all the radioactive elements except tritium, which they say is safe in small amounts. Conversely, if the tanks break, their contents could slosh out in an uncontrolled way.

Fishermen protest

Local fishermen are balking. The water, no matter how clean, has a dirty image for consumers, they say. Despite repeated tests showing most types of fish caught off Fukushima are safe to eat, diners remain hesitant. The fishermen fear any release would sound the death knell for their nascent and still fragile recovery.

“People would shun Fukushima fish again as soon as the water is released,” said Fumio Haga, a drag-net fisherman from Iwaki, a city about 50 kilometers (30 miles) down the coast from the nuclear plant.

And so the tanks remain.

​March 11, 2011

Fall is high season for saury and flounder, among Fukushima’s signature fish. It was once a busy time of year when coastal fishermen were out every morning.

Then came March 11, 2011. A 9 magnitude offshore earthquake triggered a tsunami that killed more than 18,000 people along Japan’s northeast coast. The quake and massive flooding knocked out power for the cooling systems at the Fukushima nuclear plant. Three of the six reactors had partial meltdowns. Radiation spewed into the air, and highly contaminated water ran into the Pacific.

Today, only about half of the region’s 1,000 fishermen go out, and just twice a week because of reduced demand. They participate in a fish-testing program.

Lab technicians mince fish samples at Onahama port in Iwaki, pack them in a cup for inspection and record details such as who caught the fish and where. Packaged fish sold at supermarkets carry official “safe” stickers.

Only three kinds of fish passed the test when the experiment began in mid-2012, 15 months after the tsunami. Over time, that number has increased to about 100.

The fish meet what is believed to be the world’s most stringent requirement: less than half the radioactive cesium level allowed under Japan’s national standard and one-twelfth of the U.S. or EU limit, said Yoshiharu Nemoto, a senior researcher at the Onahama testing station.

That message isn’t reaching consumers. A survey by Japan’s Consumer Agency in October found that nearly half of Japanese weren’t aware of the tests, and that consumers are more likely to focus on alarming information about possible health impacts in extreme cases, rather than facts about radiation and safety standards.

Fewer Japanese consumers shun fish and other foods from Fukushima than before, but 1 in 5 still do, according to the survey. The coastal catch of 2,000 tons last year was 8 percent of pre-disaster levels. The deep-sea catch was half of what it used to be, though scientists say there is no contamination risk that far out.

​Not yet psychologically ready

Naoya Sekiya, a University of Tokyo expert on disaster information and social psychology, said that the water from the nuclear plant shouldn’t be released until people are well-informed about the basic facts and psychologically ready.

“A release only based on scientific safety, without addressing the public’s concerns, cannot be tolerated in a democratic society,” he said. “A release when people are unprepared would only make things worse.”

He and consumer advocacy group representative Kikuko Tatsumi sit on a government expert panel that has been wrestling with the social impact of a release and what to do with the water for more than a year, with no sign of resolution.

​More radioactive water

The amount of radioactive water at Fukushima is growing, by 150 tons a day.

The reactors are damaged beyond repair, but cooling water must be constantly pumped in to keep them from overheating. That water picks up radioactivity before leaking out of the damaged containment chambers and collecting in the basements.

There, the volume of contaminated water grows, because it mixes with groundwater that has seeped in through cracks in the reactor buildings. After treatment, 210 tons is reused as cooling water, and the remaining 150 tons is sent to tank storage. During heavy rains, the groundwater inflow increases significantly, adding to the volume.

Another government panel recommended last year that the utility, known as TEPCO, dilute the water up to about 50 times and release about 400 tons daily to the sea — a process that would take almost a decade to complete. Experts note that the release of radioactive tritium water is allowed at other nuclear plants.

Tritium water from the 1979 Three Mile Island accident in the United States was evaporated, but the amount was much smaller, and still required 10 years of preparation and three more years to complete.

A new chairman at TEPCO, Takashi Kawamura, caused an uproar in the fishing community in April when he expressed support for moving ahead with the release of the water.

The company quickly backpedaled, and now says it has no plans for an immediate release and can keep storing water through 2020. TEPCO says the decision should be made by the government, because the public doesn’t trust the utility.

“Our recovery effort up until now would immediately collapse to zero if the water is released,” Iwaki abalone farmer Yuichi Manome said.

Some experts have proposed moving the tanks to an intermediate storage area, or delaying the release until at least 2023, when half the tritium that was present at the time of the disaster will have disappeared naturally.

What’s On the Menu? Augmented Reality and 3-D Food Models

At Vino Levantino wine bar in New York City, the desserts are delicious but not always so straightforward.

“We have a few desserts that are not usual … or people (are) not familiar with them,” owner Haim Amit said. “Like we have the kadaif, I mean, not everyone knows what’s kadaif.”

Rather than explain the traditional Middle Eastern dessert to customers, Amit shows them. 

Using the Kabaq augmented reality application on an iPad, he demonstrates how virtual, 3-D models of desserts can now be superimposed onto the tabletop in front of customers.

The 3-D models look incredibly realistic, not to mention mouthwatering.

How it works

“Humans are visual creatures,” Kabaq founder Alper Guler said. The tech startup is helping diners decide what to eat, and in the process, giving traditional menus a digital twist.

Guler and his team visit participating restaurants to capture 3-D images of their dishes. Using a portable, tabletop photo booth, they place dishes on a turntable inside.

“What we do is we turn the food every second and stop it, and capture from that angle,” Guler said. Cameras placed at varying heights capture all possible angles and the images are processed back at Kabaq offices to create 3-D models. Kabaq charges $99-$199 per month for their services.

Sales, fun increase

The technology is proving to be good for business. 

Amit said that overall sales have increased about 22 percent since the business began using Kabaq in June.

“We’re helping restaurant owners to raise their check averages by selling more desserts,” said Guler, who likened Kabaq to a modern-day dessert cart.

“There’s a lot of really strong applications for visualizing the food and showing the customer what they’re going to get,” said Mike Cadoux, Kabaq’s head of sales and partnerships. “If I was going to get the $17 pasta, but I see the $28 steak and it looks amazing, and I go for the $28 steak, that’s a huge value add to so many restaurants up and down the street.”

But it’s also the opportunity for a unique dining experience that Amit says has customers noticeably excited.

“They don’t expect it and they really like it. They’re surprised that we come with something digital, it’s almost like a toy,” Amit said.

On a recent night, two 20-something customers took an immediate liking to the app.

“It’s like you have the whole plate in front of you, it’s amazing,” one said.

Foodies love the technology

3-D scanning technology, in which objects are captured from all sides, is turning out to be a good fit for foodies.

Artist Romain Rouffet used 3-D scanning to create a 3-D recipe for banoffee pie that users can zoom in and out of and view from all angles. The resulting video is potentially a sign of innovations to come.

“Augmented reality and 3-D viewing and these kinds of medium … are just integral to that next generation of experience,” Cadoux said.

Seeing Microscopic Creatures from Space

The oceans and lakes are full of life, and most of it is not visible to the naked eye. In most bodies of water, every cubic centimeter contains many microorganisms — bacteria, zooplankton as well as single-cell plants called phytoplankton — all of them important links in the natural food chain. Scientists are now using satellites to observe and study these tiny creatures. VOA’s George Putic reports.

Chinese Theme Park Seeks to Ride Boom in Demand for Virtual Entertainment

Giant robots and futuristic cyberpunk castles rise out of lush mountain slopes on the outskirts of Guiyang, the capital of one of China’s poorest provinces.

Welcome to China’s first virtual reality theme park, which aims to ride a boom in demand for virtual entertainment that is set to propel tenfold growth in the country’s virtual reality market, to hit almost $8.5 billion by 2020.

The 330-acre (134-hectare) park in southwestern Guizhou province promises 35 virtual reality attractions, from shoot-’em-up games and virtual roller coasters to tours with interstellar aliens of the region’s most scenic spots.

“After our attraction opens, it will change the entire tourism structure of Guizhou province as well as China’s southwest,” Chief Executive Chen Jianli told Reuters.

“This is an innovative attraction, because it’s just different,” he said in an interview at the park, part of which is scheduled to open next February.

New growth engines

The $1.5 billion Oriental Science Fiction Valley park is part of China’s thrust to develop new drivers of growth centered on trends such as gaming, sports and cutting-edge technology, to cut reliance on traditional industries.

In the push to become a center of innovative tech, Guizhou is luring firms such as Apple Inc., which has sited its China data center there, while the world’s largest radio telescope is in nearby Pingtang county.

The park says it is the world’s first of its kind, although virtual reality-based attractions from the United States to Japan already draw interest from consumers and video gamers seeking a more immersive experience.

The Guiyang park will offer tourists bungee jumps from a huge Transformer-like robot, as well as a studio devoted to producing virtual reality movies. Most rides will use VR goggles and motion simulators to thrill users.

“You feel like you’re really there,” said Qu Zhongjie, the park’s manager of rides. “That’s our main feature.”

China’s virtual reality market is expected to grow tenfold to 55.6 billion yuan ($8.4 billion) by the end of the decade, state-backed think tank CCID has said.

Farmers in the nearby village of Zhangtianshui said they were concerned about pollution from big developments, but looked forward to the economic benefits a new theme park would bring.

Most were less sure about virtual battles or alien invasions, though.

“There are lots of good things that come out of these projects,” one farmer, Liu Guangjun, told Reuters. “As for the virtual reality, I don’t really understand it.”

Russian Tech Firm Wins US Intel Prize

Amid concerns about Russian hacking and online influence, Russian technology firm NtechLab has won a prize awarded by the United States intelligence community. VOA’s Moscow Bureau visited NtechLab to ask its general director about the award, the technology, and concerns about privacy.

Tech Firms Scrounging for Skilled Workers Training Their Own

Some information technology companies are growing so concerned about not find enough digital talent that they’re training their own.

 

IBM, Amazon and Microsoft all now have apprenticeship programs that pay workers learning on-the-job while they build IT skills. The programs cost companies tens of thousands of dollars per trainee.

 

IBM Vice President Joanna Daly says the apprenticeship program the tech giant started last month will help fill the several hundred vacant early-career IT jobs in the U.S. Rhode Island-based Carousel Industries executive Tim Hebert says the company’s apprentices are loyal and stay for years.

 

The U.S. Bureau of Labor Statistics says the median pay last year for computer and information technology occupations was about $83,000, compared to $37,000 for all jobs.

 

What Happens Once ‘Net Neutrality’ Rules Bite the Dust?

The Federal Communications Commission formally released a draft of its plan to kill net-neutrality rules, which equalized access to the internet and prevented broadband providers from favoring their own apps and services.

Now the question is: What comes next?

‘Radical departure’

The FCC’s move will allow companies like Comcast, AT&T and Verizon to charge internet companies for speedier access to consumers and to block outside services they don’t like. The change also axes a host of consumer protections, including privacy requirements and rules barring unfair practices that gave consumers an avenue to pursue complaints about price gouging.

FCC Chairman Ajit Pai says his plan eliminates unnecessary regulation. But many worry that his proposal will stifle small tech firms and leave ordinary citizens more at the mercy of cable and wireless companies.

“It would be a radical departure from what previous (FCC) chairs, of both parties, have done,” said Gigi Sohn, a former adviser to Tom Wheeler, the Obama-era FCC chairman who enacted the net neutrality rules now being overturned. “It would leave consumers and competition completely unprotected.”

During the last Republican administration, that of George W. Bush, FCC policy held that people should be able to see what they want on the internet and to use the services they preferred. But attempts to enshrine that net-neutrality principle in regulation never held up in court – at least until Wheeler pushed through the current rules now slated for termination.

Pai’s proposals stand a good chance of enactment at the next FCC meeting in December. But there will be lawsuits to challenge them.

More details

The formal proposal reveals more details of the plan than were in the FCC’s Tuesday press release. For instance, if companies like Comcast, AT&T and Verizon decide to block a particular app, throttle data speeds for a rival service or offer faster speeds to companies who pay for it, they merely need to disclose their policies for doing so.

The FCC also says it will pre-empt state rules on privacy and net neutrality that contradict its approach. Verizon has noted that New York has several privacy bills pending, and that the California legislature has suggested coming up with its own version of net neutrality rules should the federal versions perish.

The plan would leave complaints about deceptive behavior and monitor privacy to the Federal Trade Commission, which already regulates privacy for internet companies like Google and Facebook.

Best behavior

Broadband providers are promising to be on their best behavior. Comcast said it doesn’t and won’t block, throttle or discriminate against lawful content. AT&T said that “all major ISPs have publicly committed to preserving an open internet” and that any ISP “foolish” enough to manipulate what’s available online for customers will be “quickly and decisively called out.” Verizon said that “users should be able to access the internet when, where, and how they choose.”

Some critics don’t put much weight on those promises, noting that many providers have previously used their networks to disadvantage rivals. For example, the Associated Press in 2007 found Comcast was blocking some file-sharing. AT&T blocked Skype and other internet calling services on its network on the iPhone until 2009.

But others suggest fear of a public uproar will help restrain egregious practices such as blocking and throttling. “I’m not sure there’s any benefit to them doing that,” said Sohn. “It’s just going to get people angry at them for no good reason. They don’t monetize that.”

Fast lanes, slow lanes

Sohn, however, suggests there’s reason to worry about more subtle forms of discrimination, such as “paid prioritization.” That’s a term for internet “fast lanes,” where companies that can afford it would pay AT&T, Verizon and Comcast for faster or better access to consumers.

That would leave startups and institutions that aren’t flush with cash, like libraries or schools, relegated to slower service, said Corynne McSherry, legal director at the Electronic Frontier Foundation, a digital-rights group. In turn, startups would find it harder to attract investors, Sohn said.

Michael Cheah, general counsel of the video startup Vimeo, said broadband companies will try to lay groundwork for a two-tiered internet – one where cash-strapped companies and services are relegated to the slow lane. To stay competitive, small companies would need to pony up for fast lanes if they could – but those costs would ultimately find their way to consumers.

The view is different at the Information Technology and Innovation Foundation, a Washington, D.C., think tank funded by Google and other established tech companies. Doug Brake, a telecom policy analyst at the foundation, said there’s little chance broadband companies will engage in “shenanigans,” given how unpopular they already are with the public.

Brake likewise played down the threat of internet fast lanes, arguing that they’ll only be useful in limited situations such as high-quality teleconferencing. Like the FCC, he argued that antitrust law can serve to deter “potentially anticompetitive” behavior by internet providers.
