Solar Team Eindhoven crafts solar-powered family car (video)

Solar Team Eindhoven claims first solarpowered family car

The solar-powered cars we've seen to date are usually built for just one person -- not very useful when many of us need to carry passengers. TU/e's Solar Team Eindhoven just brought some much-needed realism on that front by unveiling Stella, which it claims is the world's first solar-powered family car. The vehicle's combination of efficient solar cells with lightweight construction allows such radical concepts as back seats and a trunk while maintaining a 373-mile range. The barebones design won't rival most modern cars for luxury, but it's also energy-positive -- in typical use, it can contribute back to the power grid. You may even see it outside of competitions; while Stella is designed with October's World Solar Challenge in mind, Solar Team Eindhoven plans to make the car road-legal. Let's hope we catch it putting around Dutch streets.

REFLECTIONS | Mandela's thoughts on death and dying - InterAksyon

JOHANNESBURG -- Haunted by death during his long anti-apartheid struggle, Nelson Mandela looked toward his own "eternal sleep" as a man who fulfilled his duty to his people.

He was willing to die for democracy, the young black activist said during the 1963-64 trial that would send him to prison for 27 years.

"It is an ideal which I hope to live for and to achieve. But if needs be, it is an ideal for which I am prepared to die," he told judges of the white-minority apartheid regime.

Nearly 50 years later the 94-year-old is critically ill, fighting a stubborn pulmonary infection.

The country's presidency has prepared people for the icon's passing after his fourth hospitalization this year.

"He never gave death a great deal of thought but he never wanted anything fancy," a family friend told the weekly Mail & Guardian.

A simple A4-page testament quoted in the paper asks a modest last resting place, true to the unpretentious image he cultivated from his presidency from 1994 to 1999.

He allowed himself one fantasy 10 years ago: fellow anti-apartheid fighter and political mentor Walter Sisulu welcoming him to paradise with mobilization chants and an ANC enrolment form.

After leading South Africa to a peaceful transition and the first all-race elections in 1994, the Nobel peace laureate regarded his life task complete.

"When a man has done what he considers to be his duty to his people and his country, he can rest in peace," he said in 1996.

"I believe I have made that effort and that is, therefore, why I will sleep for the eternity."

Throughout his long imprisonment Mandela lost friends and family, often unable to say goodbye in person.

Already refused permission to attend his mother's funeral, he mourned his firstborn son Thembekile's death alone in his Robben Island cell in 1969.

"He was called to the office. We were all in the courtyard, but instead of coming back to us he went straight to his cell and got on his mattress," his old cellmate Ahmed Kathrada remembered years later.

"It was similar when his mother died. He just kept very quiet and mourned alone."

By 1987, feeling increasingly alone, Mandela became despondent.

"So many relatives and friends have died over these last twenty years, that it seems the world itself is dying," he wrote in a letter.

Today thousands of bouquets and Get Well cards at his Johannesburg house and hospital echo his eulogy at the burial of communist leader Joe Slovo in 1995.

"Men and women of rare qualities are few and hard to come by. And when they depart, the sense of loss is made the more profound and the more difficult to manage," he said.

Mandela will eventually rest surrounded by his family's remains, according to his cultural Xhosa nation's tradition.

"My family's here and I'd like to be buried here at home," he said at the Mandela cemetery in a 2003 documentary in his childhood village Qunu.

A row of trees surrounds the graveyard off the N2 highway in the rolling Eastern Cape province hills, around 500 meters from his house.

Simple headstones bearing the family name stand out from the yellowed grass.

In a 2006 documentary he was clear on how he wanted to be remembered.

"I would like it to be said that, 'Here lies a man who has done his duty on earth.' That is all."

The Prince of Persia series has been around for almost a quarter of a century now, but it's back on July 25 with an all new game set to hit iOS. The Shadow and the Flame will follow the tried and tested sideways scrolling formula we know and love from the previous Prince of Persia games, but throws some stunning visuals into the mix as well. The official description:

Continue the age old saga of a wanderer who was born a Prince! The wanderer returns, in search of his unknown past on a journey to redefine his future.

The new game promises 14 levels of gameplay, weapons galore and a multiple enemy combat system with an apparent tactical edge to it. It will be available for both the iPhone and the iPad, and I'm sure theres a lot of gamers out there eager to play this one. Who's excited for it?

Try getting a weapon on a plane and you'll end up on...Instagram?

This Instagram image was taken by the TSA. No, really. It shows a weapon they confiscated from someone's carry on luggage at Austin Bergstrom airport. The TSA now has their own Instagram account and has taken to posting images of some of the things they're confiscating at airports across the U.S. It's both shocking, and re-assuring at the same time; shocking items such as loaded guns were found at all, but re-assuring that the TSA is visibly doing a job to protect our safety, even if they are telling us about it themselves.

The TSA is no stranger to using the power of the Internet to talk about their successes, but with the enormous, global reach of Instagram, this latest method really can reach everyone. Further still, they're pretty good Instagram photos as well; composed, 'properly' filtered and framed!

It could be seen as an unusual tactic, but as todays world ever changes towards mobile, and apps like Instagram are great examples of this, there's no reason why an enforcement agency like the TSA shouldn't use mobile to get their point across. What do you guys think of this? Any other government agencies you'd like to see take to Instagram?

HTC confirms One S will no longer receive Android updates

HTC confirms One S will no longer receive Android updates

It's not a Nexus, so suspend your disbelief: HTC's One S will not be getting any further Android updates. That's right, One S owners, your device is now officially a relic. In a statement released to the press, HTC today confirmed that the mid-ranger, which bowed last year in tandem with the One X, will remain frozen on 4.1.1 Jelly Bean. That means current owners will have to look elsewhere (read: developer forums) for unofficial access to Sense 5 ROMs and the latest tweaks Google's packed into Android 4.2 updates. We can't really lament the loss of BlinkFeed, but it sure would've been nice to see HTC port Zoe over to the device. At the very least, this makes a strong case for that Google Play edition One and its promise of consistent updates.

Cluster spacecraft detects elusive space wind

July 2, 2013 ? A new study provides the first conclusive proof of the existence of a space wind first proposed theoretically over 20 years ago. By analysing data from the European Space Agency's Cluster spacecraft, researcher Iannis Dandouras detected this plasmaspheric wind, so-called because it contributes to the loss of material from the plasmasphere, a donut-shaped region extending above Earth's atmosphere. The results are published today in Annales Geophysicae, a journal of the European Geosciences Union (EGU).

"After long scrutiny of the data, there it was, a slow but steady wind, releasing about 1 kg of plasma every second into the outer magnetosphere: this corresponds to almost 90 tonnes every day. It was definitely one of the nicest surprises I've ever had!" said Dandouras of the Research Institute in Astrophysics and Planetology in Toulouse, France.

The plasmasphere is a region filled with charged particles that takes up the inner part of Earth's magnetosphere, which is dominated by the planet's magnetic field.

To detect the wind, Dandouras analysed the properties of these charged particles, using information collected in the plasmasphere by ESA's Cluster spacecraft. Further, he developed a filtering technique to eliminate noise sources and to look for plasma motion along the radial direction, either directed at Earth or outer space.

As detailed in the new Annales Geophysicae study, the data showed a steady and persistent wind carrying about a kilo of the plasmasphere's material outwards each second at a speed of over 5,000 km/h. This plasma motion was present at all times, even when Earth's magnetic field was not being disturbed by energetic particles coming from the Sun.

Researchers predicted a space wind with these properties over 20 years ago: it is the result of an imbalance between the various forces that govern plasma motion. But direct detection eluded observation until now.

"The plasmaspheric wind is a weak phenomenon, requiring for its detection sensitive instrumentation and detailed measurements of the particles in the plasmasphere and the way they move," explains Dandouras, who is also the vice-president of the EGU Planetary and Solar System Sciences Division.

The wind contributes to the loss of material from Earth's top atmospheric layer and, at the same time, is a source of plasma for the outer magnetosphere above it. Dandouras explains: "The plasmaspheric wind is an important element in the mass budget of the plasmasphere, and has implications on how long it takes to refill this region after it is eroded following a disturbance of the planet's magnetic field. Due to the plasmaspheric wind, supplying plasma -- from the upper atmosphere below it -- to refill the plasmasphere is like pouring matter into a leaky container."

The plasmasphere, the most important plasma reservoir inside the magnetosphere, plays a crucial role in governing the dynamics of Earth's radiation belts. These present a radiation hazard to satellites and to astronauts travelling through them. The plasmasphere's material is also responsible for introducing a delay in the propagation of GPS signals passing through it.

"Understanding the various source and loss mechanisms of plasmaspheric material, and their dependence on the geomagnetic activity conditions, is thus essential for understanding the dynamics of the magnetosphere, and also for understanding the underlying physical mechanisms of some space weather phenomena," says Dandouras.

Michael Pinnock, Editor-in-Chief of Annales Geophysicae recognises the importance of the new result. "It is a very nice proof of the existence of the plasmaspheric wind. It's a significant step forward in validating the theory. Models of the plasmasphere, whether for research purposes or space weather applications (e.g. GPS signal propagation) should now take this phenomenon into account," he wrote in an email.

Similar winds could exist around other planets, providing a way for them to lose atmospheric material into space. Atmospheric escape plays a role in shaping a planet's atmosphere and, hence, its habitability.
