George Duke Dead: Legendary Musician Dies At 67

George Duke, legendary jazz, R&B, funk musician has died at age 67.
(from huffingtonpost.com)

According to New York Daily News, Duke passed away on Monday, August 5, in Los Angeles. His cause of death has not yet been determined.

Throughout his career, which spanned over 40 years, the eclectic musician crafted a string of hits including the timeless classic “No Rhyme No Reason,” and worked alongside music legends including Smokey Robinson, Gladys Knight, Anita Baker, Miles Davis, Michael Jackson and Barry Manilow, to name a few.

Former Supremes member, Sherrie Payne, who was a close family friend, released a statement on the news of Duke’s passing;

I just received the devastating and sad news that the great musician, George Duke, passed away this evening at St. John’s hospital in L.A. It was just one year earlier, July 18th, that his beloved wife and my friend, Corine, went to be with the Lord. Please keep his sons, Rasheed and John, in your prayers.

Duke released his latest opus, “DreamWeaver,” which was dedicated to his late wife, Corine, who died a year ago from cancer.

Duke’s music will continue to live on through a new generation of listeners and has been sampled by many artists including Kanye West, Daft Punk, and A Tribe Called Quest among many others.

Hot-Fire Tests Show 3-D Printed Rocket Parts Rival Traditionally Manufactured Parts

Propulsion engineer Sandra Greene, left, and test engineer Cynthia Sprader recently completed a series of test firings at NASA’s Marshall Space Flight Center in Huntsville, Alabama.(from www.nasa.gov)

What can survive blazing temperatures of almost 6,000 degrees Fahrenheit without melting? What did not break apart at extreme pressures? What is made by a new process that forms a complex part in just one piece? What takes less than three weeks to go from manufacturing to testing? What can reduce the costs of expensive rocket parts by 60 percent or more?

Answer: 3-D printed parts

Engineers know that 3-D printed rocket parts have the potential to save NASA and industry money and to open up new affordable design possibilities for rockets and spacecraft. But until recently, no one had tested rocket parts critical to engine combustion in a hot-fire environment.

NASA engineers at the Marshall Space Flight Center in Huntsville, Ala., not only put rocket engine parts to the test but also were able to compare their performance to parts made the old-fashioned way with welds and multiple parts during planned subscale acoustic tests for the Space Launch System (SLS) heavy-lift rocket. In little more than a month, Marshall engineers built two subscale injectors with a specialized 3-D printing machine and completed 11 mainstage hot-fire tests, accumulating 46 seconds of total firing time at temperatures nearing 6,000 degrees Fahrenheit while burning liquid oxygen and gaseous hydrogen.

“We saw no difference in performance of the 3-D printed injectors compared to the traditionally manufactured injectors,” said Sandra Elam Greene, the propulsion engineer who oversaw the tests and inspected the components afterward. “Two separate 3-D printed injectors operated beautifully during all hot-fire tests.”

Post-test inspections showed the injectors remained in such excellent condition and performed so well the team will continue to put them directly in the line of fire. In addition to the SLS acoustic tests, Greene and her team tested a more complex assembly of a 3-D printed injector and thrust chamber liner made by Directed Manufacturing, Inc., of Austin, Texas. Marshall engineers transferred a second 3-D printed injector to NASA’s Stennis Space Center in Mississippi, where it will continue to accumulate hot-fire time to test its durability.

“Rocket engines are complex, with hundreds of individual components that many suppliers typically build and assemble, so testing an engine component built with a new process helps verify that it might be an affordable way to make future rockets,” said Chris Singer, director of the Marshall Center’s Engineering Directorate. “The additive manufacturing process has the potential to reduce the time and cost associated with making complex parts by an order of magnitude.”

Traditional subscale rocket injectors for early SLS acoustic tests took six months to fabricate, had four parts, five welds and detailed machining and cost more than $10,000 each. Marshall materials engineers built the same injector in one piece by sintering Inconel steel powder with a state-of-the-art 3-D printer. After minimal machining and inspection with computer scanning, it took just three weeks for the part to reach the test stand and cost less than $5,000 to manufacture.

“It took about 40 hours from start to finish to make each injector using a 3-D printing process called selective laser melting, and another couple of weeks to polish and inspect the parts,” explained Ken Cooper, a Marshall materials engineer whose team made the part. “This allowed the propulsion engineers to take advantage of an existing SLS test series to examine how 3-D printed parts performed compared to traditional parts with a similar design.”

Since additive manufacturing machines have has become more affordable, varied, and sophisticated, this materials process now offers many possibilities for making every phase of NASA missions more affordable. The SLS injector tests are just one example of NASA’s efforts to fabricate and test 3-D printed parts in relevant environments similar to those experienced during NASA missions. The SLS injector test series complements a series of liquid oxygen and gaseous hydrogen rocket assembly firings at NASA’s Glenn Research Center in Cleveland, which hot-fire tested an additively manufactured, select laser melted injector developed through collaboration of industry and government agencies. A J-2X engine exhaust port cover made at the Marshall Center became the first 3-D printed part tested during a full-scale engine hot-fire test at NASA’s Stennis Center. Marshall materials engineers are currently making a baffle critical for pogo vibration mitigation; it will be tested at Marshall and Stennis and is a potential candidate for the first SLS mission in 2017. Marshall engineers are finishing up ground tests with Made in Space, a Moffett Field, California company working with NASA to develop and test a 3-D printer that will build tools on the International Space Station next year. NASA’s Johnson Space Center in Houston is even exploring printing food in space.

“At NASA, we recognize ground-based and in-space additive manufacturing offer the potential for new mission opportunities, whether printing rocket parts, tools or entire spacecraft,” Singer said. “Additive manufacturing will improve affordability from design and development to flight and operations, enabling every aspect of sustainable long-term human space exploration.”

NASA is a leading partner in the National Network for Manufacturing Innovation and the Advanced Manufacturing Initiative, which explores using additive manufacturing and other advanced materials processes to reduce the cost of spaceflight.

78,000 sign up for one-way mission to Mars

Amersfoort, 7th May 2013 – Just two weeks into the nineteen week application period, more than seventy-eight thousand people have applied to the Mars One astronaut selection program in the hope of becoming a Mars settler in 2023.

Mars One has received applications from over 120 countries. Most applications come from USA (17324), followed by China (10241), United Kingdom (3581), Russia, Mexico, Brazil, Canada, Colombia, Argentina and India.Bas Lansdorp, Mars One Co-Founder and CEO said: “With seventy-eight thousand applications in two weeks, this is turning out to be the most desired job in history. These numbers put us right on track for our goal of half a million applicants.

Mars One is a mission representing all humanity and its true spirit will be justified only if people from the entire world are represented. I’m proud that this is exactly what we see happening,” he said.

As part of the application every applicant is required to explain his/her motivation behind their decision go to Mars in an one minute video. Many applicants are choosing to publish this video on the Mars One website. These are openly accessible on applicants.mars-one.com.

Applicants we have received come from a very wide range of personalities, professions and ages. This is significant because what we are looking for is not restricted to a particular background. From Round 1 we will take forward the most committed, creative, resilient and motivated applicants,” said Dr. Norbert Kraft, Mars One Chief Medical Officer.

Mars One will continue to receive online applications until August 31st 2013. From all the applicants in Round 1, regional reviewers will select around 50-100 candidates for Round 2 in each of the 300 geographic regions in the world that Mars One has identified.

Four rounds make the selection process, which will come to an end in 2015; Mars One will then employ 28-40 candidates, who will train for around 7 years. Finally an audience vote will elect one of groups in training to be the envoys of humanity to Mars.

Stirling Engines & The E-Cat

Talk on the Journal of Nuclear Physics has now turned to the Stirling engine. While the E-Cat community mourns the loss of Prof. Focardi – co-inventor of the E-Cat, and Andrea Rossi faces threats against his safety if he leaves the United States, he continues to forge ahead with adaptations to his technology. The use of Stirling engines in his work means that the Hot Cat has progressed to the point where Mr. Rossi and his team are attempting to use the Hot Cat for electricity production.(from ecatreport.com)

On June 27th, Andrea Rossi posted on the JONP:

“To the Readers expert in Sterling Engine or manufacturers of Sterling Engines:

“Please send your proposals for Sterling Engines to be coupled with the E-Cats )power 5kW and 10 kW). The best offers will be bought for testing. Ask more details to info@leonardocorp1996.com

“Attention of Dr. Andrea Rossi.”

This is exciting news, indicating that work on the E-Cat has stepped into a new phase of development. Several commenters on the JONP jumped in with suggestions about Stirling Engines. Marchesi Marco posted:

“I’ve just read…that you’re working on electricity production. Maybe are you working on it in the usual sense with a steam turbine or could you re-evaluate the idea of a simple Stirling engine! An increasing Delta-T will augment the efficiency, so the Hot-Cat is the best choice…Or, maybe it’s an old idea, just tried and not working?”

Rossi replied:

“Yes, the Sterling Engine is an option with the new temperatures. We are studying also this kind of coupling.”

Pekka Janhunen, a frequent commenter on the JONP, asked:

“I assume that the 5 or 10 kW refers to the thermal output power of the E-Cat, not the mechanical output power of the Stirling engine which is lower by factor 3 or more. Correct?”

Dr. Rossi replied:

“yes, correct. I want to add that we are not interested to proposals of concepts or patents to be developed: we need a device ready to be tested immediately.”

The immediacy of the need for a working Stirling engine indicates that the testing phase and R&D for this technology is here, and ready to be fully developed.

Some suggestions for sources of Stirling engines, while promising leads, tend to run into patent pending situations, or into technology that is as new as the Hot Cat, itself. Chris Johnson recommended a promising company that develops this technology, but it is not patented yet, nor under production. Mr. Rossi is typically very open to new ideas and variations on the technologies involved with his E-Cats, even changing some of the construction aspects as per some suggestions from his readers. A good example of this is when he did away with the inner chamber of the reactor. So, for him to be this adamant about a working engine, it indicates that he and his team are definitely ready to move on to the next order of business with the Hot Cat.

SERGIO FOCARDI, PROF. EMERITUS OF THE UNIVERSITY OF BOLOGNA, IS DEAD . I RECEIVED THE NEW FROM ITALY TODAY AT 3 A.M., USA EASTERN TIME, FEW MINUTES AGO.
We all have lost one of the greatest scientists in the field of the LENR.
For me he has been a tremendous ally, he helped our work enormously and the safety certifications that we are obtaining are the fruit of his consulting during the last 7 years. For me he has been also a teacher for Physics and Mathematics, anytime I needed his help in these matters to better understand the theory behind the effect of the E-Cat.
He has always worked with us with total, absolute and disinterested attitude, thinking only the the interest of the Science behind the LENR.
All the newspapers of the scientific world will say what he has been in the Scientific and University world and his enormous legacy: he has been Professor of Physics, Mathematic, he has been the Dean of the Scientific Faculties of the Alma Mater University of Bologna and the founder of the Cesena branch of the University of Bologna. His pubilcations in the fields of Mathematics and Physics are monumental.
Now, after a long period of illness, that obviously all his friends have taken secret to respect his privacy, he ceased to suffer and starts a new duty for God under anothe form of life. I am sure he will continue to look after my work from where he is now.
See you soon, my great Friend and Master Sergio! I will never forget our work together and that day in the Brasimone Nuclear facility.
Yours Andrea Rossi

Edward Snowden: the whistleblower behind the NSA surveillance revelations

The 29-year-old source behind the biggest intelligence leak in the NSA’s history explains his motives, his uncertain future and why he never intended on hiding in the shadows (from guardian.co.uk)

The individual responsible for one of the most significant leaks in US political history is Edward Snowden, a 29-year-old former technical assistant for the CIA and current employee of the defence contractor Booz Allen Hamilton. Snowden has been working at the National Security Agency for the last four years as an employee of various outside contractors, including Booz Allen ( ISIN: US0995021062 ) and Dell (ISIN: US24702R1014).

The Guardian, after several days of interviews, is revealing his identity at his request. From the moment he decided to disclose numerous top-secret documents to the public, he was determined not to opt for the protection of anonymity. “I have no intention of hiding who I am because I know I have done nothing wrong,” he said.

Snowden will go down in history as one of America’s most consequential whistleblowers, alongside Daniel Ellsberg and Bradley Manning. He is responsible for handing over material from one of the world’s most secretive organisations – the NSA.

In a note accompanying the first set of documents he provided, he wrote: “I understand that I will be made to suffer for my actions,” but “I will be satisfied if the federation of secret law, unequal pardon and irresistible executive powers that rule the world that I love are revealed even for an instant.”

Despite his determination to be publicly unveiled, he repeatedly insisted that he wants to avoid the media spotlight. “I don’t want public attention because I don’t want the story to be about me. I want it to be about what the US government is doing.”

He does not fear the consequences of going public, he said, only that doing so will distract attention from the issues raised by his disclosures. “I know the media likes to personalise political debates, and I know the government will demonise me.”

Despite these fears, he remained hopeful his outing will not divert attention from the substance of his disclosures. “I really want the focus to be on these documents and the debate which I hope this will trigger among citizens around the globe about what kind of world we want to live in.” He added: “My sole motive is to inform the public as to that which is done in their name and that which is done against them.”

He has had “a very comfortable life” that included a salary of roughly $200,000, a girlfriend with whom he shared a home in Hawaii, a stable career, and a family he loves. “I’m willing to sacrifice all of that because I can’t in good conscience allow the US government to destroy privacy, internet freedom and basic liberties for people around the world with this massive surveillance machine they’re secretly building.”

‘I am not afraid, because this is the choice I’ve made’

Three weeks ago, Snowden made final preparations that resulted in last week’s series of blockbuster news stories. At the NSA office in Hawaii where he was working, he copied the last set of documents he intended to disclose.

He then advised his NSA supervisor that he needed to be away from work for “a couple of weeks” in order to receive treatment for epilepsy, a condition he learned he suffers from after a series of seizures last year.

As he packed his bags, he told his girlfriend that he had to be away for a few weeks, though he said he was vague about the reason. “That is not an uncommon occurrence for someone who has spent the last decade working in the intelligence world.”

On May 20, he boarded a flight to Hong Kong, where he has remained ever since. He chose the city because “they have a spirited commitment to free speech and the right of political dissent”, and because he believed that it was one of the few places in the world that both could and would resist the dictates of the US government.

In the three weeks since he arrived, he has been ensconced in a hotel room. “I’ve left the room maybe a total of three times during my entire stay,” he said. It is a plush hotel and, what with eating meals in his room too, he has run up big bills.

He is deeply worried about being spied on. He lines the door of his hotel room with pillows to prevent eavesdropping. He puts a large red hood over his head and laptop when entering his passwords to prevent any hidden cameras from detecting them.

Though that may sound like paranoia to some, Snowden has good reason for such fears. He worked in the US intelligence world for almost a decade. He knows that the biggest and most secretive surveillance organisation in America, the NSA, along with the most powerful government on the planet, is looking for him.

Since the disclosures began to emerge, he has watched television and monitored the internet, hearing all the threats and vows of prosecution emanating from Washington.

And he knows only too well the sophisticated technology available to them and how easy it will be for them to find him. The NSA police and other law enforcement officers have twice visited his home in Hawaii and already contacted his girlfriend, though he believes that may have been prompted by his absence from work, and not because of suspicions of any connection to the leaks.

“All my options are bad,” he said. The US could begin extradition proceedings against him, a potentially problematic, lengthy and unpredictable course for Washington. Or the Chinese government might whisk him away for questioning, viewing him as a useful source of information. Or he might end up being grabbed and bundled into a plane bound for US territory.

“Yes, I could be rendered by the CIA. I could have people come after me. Or any of the third-party partners. They work closely with a number of other nations. Or they could pay off the Triads. Any of their agents or assets,” he said.

“We have got a CIA station just up the road – the consulate here in Hong Kong – and I am sure they are going to be busy for the next week. And that is a concern I will live with for the rest of my life, however long that happens to be.”

Having watched the Obama administration prosecute whistleblowers at a historically unprecedented rate, he fully expects the US government to attempt to use all its weight to punish him. “I am not afraid,” he said calmly, “because this is the choice I’ve made.”

He predicts the government will launch an investigation and “say I have broken the Espionage Act and helped our enemies, but that can be used against anyone who points out how massive and invasive the system has become”.

The only time he became emotional during the many hours of interviews was when he pondered the impact his choices would have on his family, many of whom work for the US government. “The only thing I fear is the harmful effects on my family, who I won’t be able to help any more. That’s what keeps me up at night,” he said, his eyes welling up with tears.

‘You can’t wait around for someone else to act’

Snowden did not always believe the US government posed a threat to his political values. He was brought up originally in Elizabeth City, North Carolina. His family moved later to Maryland, near the NSA headquarters in Fort Meade.

By his own admission, he was not a stellar student. In order to get the credits necessary to obtain a high school diploma, he attended a community college in Maryland, studying computing, but never completed the coursework. (He later obtained his GED.)

In 2003, he enlisted in the US army and began a training program to join the Special Forces. Invoking the same principles that he now cites to justify his leaks, he said: “I wanted to fight in the Iraq war because I felt like I had an obligation as a human being to help free people from oppression”.

He recounted how his beliefs about the war’s purpose were quickly dispelled. “Most of the people training us seemed pumped up about killing Arabs, not helping anyone,” he said. After he broke both his legs in a training accident, he was discharged.

After that, he got his first job in an NSA facility, working as a security guard for one of the agency’s covert facilities at the University of Maryland. From there, he went to the CIA, where he worked on IT security. His understanding of the internet and his talent for computer programming enabled him to rise fairly quickly for someone who lacked even a high school diploma.

By 2007, the CIA stationed him with diplomatic cover in Geneva, Switzerland. His responsibility for maintaining computer network security meant he had clearance to access a wide array of classified documents.

That access, along with the almost three years he spent around CIA officers, led him to begin seriously questioning the rightness of what he saw.

He described as formative an incident in which he claimed CIA operatives were attempting to recruit a Swiss banker to obtain secret banking information. Snowden said they achieved this by purposely getting the banker drunk and encouraging him to drive home in his car. When the banker was arrested for drunk driving, the undercover agent seeking to befriend him offered to help, and a bond was formed that led to successful recruitment.

“Much of what I saw in Geneva really disillusioned me about how my government functions and what its impact is in the world,” he says. “I realised that I was part of something that was doing far more harm than good.”

He said it was during his CIA stint in Geneva that he thought for the first time about exposing government secrets. But, at the time, he chose not to for two reasons.

First, he said: “Most of the secrets the CIA has are about people, not machines and systems, so I didn’t feel comfortable with disclosures that I thought could endanger anyone”. Secondly, the election of Barack Obama in 2008 gave him hope that there would be real reforms, rendering disclosures unnecessary.

He left the CIA in 2009 in order to take his first job working for a private contractor that assigned him to a functioning NSA facility, stationed on a military base in Japan. It was then, he said, that he “watched as Obama advanced the very policies that I thought would be reined in”, and as a result, “I got hardened.”

The primary lesson from this experience was that “you can’t wait around for someone else to act. I had been looking for leaders, but I realised that leadership is about being the first to act.”

Over the next three years, he learned just how all-consuming the NSA’s surveillance activities were, claiming “they are intent on making every conversation and every form of behaviour in the world known to them”.

He described how he once viewed the internet as “the most important invention in all of human history”. As an adolescent, he spent days at a time “speaking to people with all sorts of views that I would never have encountered on my own”.

But he believed that the value of the internet, along with basic privacy, is being rapidly destroyed by ubiquitous surveillance. “I don’t see myself as a hero,” he said, “because what I’m doing is self-interested: I don’t want to live in a world where there’s no privacy and therefore no room for intellectual exploration and creativity.”

Once he reached the conclusion that the NSA’s surveillance net would soon be irrevocable, he said it was just a matter of time before he chose to act. “What they’re doing” poses “an existential threat to democracy”, he said.

A matter of principle

As strong as those beliefs are, there still remains the question: why did he do it? Giving up his freedom and a privileged lifestyle? “There are more important things than money. If I were motivated by money, I could have sold these documents to any number of countries and gotten very rich.”

For him, it is a matter of principle. “The government has granted itself power it is not entitled to. There is no public oversight. The result is people like myself have the latitude to go further than they are allowed to,” he said.

His allegiance to internet freedom is reflected in the stickers on his laptop: “I support Online Rights: Electronic Frontier Foundation,” reads one. Another hails the online organisation offering anonymity, the Tor Project.

Asked by reporters to establish his authenticity to ensure he is not some fantasist, he laid bare, without hesitation, his personal details, from his social security number to his CIA ID and his expired diplomatic passport. There is no shiftiness. Ask him about anything in his personal life and he will answer.

He is quiet, smart, easy-going and self-effacing. A master on computers, he seemed happiest when talking about the technical side of surveillance, at a level of detail comprehensible probably only to fellow communication specialists. But he showed intense passion when talking about the value of privacy and how he felt it was being steadily eroded by the behaviour of the intelligence services.

His manner was calm and relaxed but he has been understandably twitchy since he went into hiding, waiting for the knock on the hotel door. A fire alarm goes off. “That has not happened before,” he said, betraying anxiety wondering if was real, a test or a CIA ploy to get him out onto the street.

Strewn about the side of his bed are his suitcase, a plate with the remains of room-service breakfast, and a copy of Angler, the biography of former vice-president Dick Cheney.

Ever since last week’s news stories began to appear in the Guardian, Snowden has vigilantly watched TV and read the internet to see the effects of his choices. He seemed satisfied that the debate he longed to provoke was finally taking place.

He lay, propped up against pillows, watching CNN’s Wolf Blitzer ask a discussion panel about government intrusion if they had any idea who the leaker was. From 8,000 miles away, the leaker looked on impassively, not even indulging in a wry smile.

Snowden said that he admires both Ellsberg and Manning, but argues that there is one important distinction between himself and the army private, whose trial coincidentally began the week Snowden’s leaks began to make news.

“I carefully evaluated every single document I disclosed to ensure that each was legitimately in the public interest,” he said. “There are all sorts of documents that would have made a big impact that I didn’t turn over, because harming people isn’t my goal. Transparency is.”

He purposely chose, he said, to give the documents to journalists whose judgment he trusted about what should be public and what should remain concealed.

As for his future, he is vague. He hoped the publicity the leaks have generated will offer him some protection, making it “harder for them to get dirty”.

He views his best hope as the possibility of asylum, with Iceland – with its reputation of a champion of internet freedom – at the top of his list. He knows that may prove a wish unfulfilled.

But after the intense political controversy he has already created with just the first week’s haul of stories, “I feel satisfied that this was all worth it. I have no regrets.”
