Meet the Makers of an Exotic (Partially) 3-D Printed Car (2 Videos) 14 14

Last month, in a story headlined 3D Printed Supercar Chassis Unveiled, we promised video interviews with builders Kevin and Brad "in the near future." Here they are. First, we have Kevin Czinger, Founder & CEO of Divergent Microfactories. He says the way we build cars is more important from an environmental standpoint than how we fuel them, and that the way we make cars now is a lot less efficient and a lot more expensive than it needs to be. Divergent's first demo vehicle, the Blade, is a tandem-seating 700 HP supercar its makers say does 0 - 60 in 2.5 seconds. Price? No word yet, but it's safe to assume "plenty" might be an accurate guess.

In the second video, Blade project lead Brad Balzer goes into detail about how, why, and where they use 3-D printing, and explains the modular nature of their car chassis design. He says they don't need to change many parts to go from ultra-sports car to pickup truck. He also says that while Divergent Microfactories is working on cars right now, their manufacturing system can be applied to many different industries. Indeed, their long-range goal is to help people build microfactories making many different kinds of products faster, more flexibly, and for less money than it takes to make similar manufactured items today.

Note: The transcript covers both videos and has a little 'bonus' material in it, too.

NASA To Waste $150 Million On SLS Engine That Will Be Used Once 111 111

schwit1 writes: NASA's safety panel has noticed that NASA's SLS program either plans to spend $150 million human-rating a rocket engine it will only use once, or will fly a manned mission without human-rating that engine.

"The Block 1 SLS is the 'basic model,' sporting a Delta Cryogenic Second Stage (DCSS), renamed the Interim Cryogenic Propulsion System (ICPS) for SLS. The current plan calls for this [interim] stage to be used on [the unmanned] Exploration Mission -1 (EM-1) and [manned] Exploration Mission -2 (EM-2), prior to moving to the [Exploration Upper Stage] — also to be built by Boeing — that will become the workhorse for SLS. However, using the [interim upper stage] on a crewed mission will require it to be human rated. It is likely NASA will also need to fly the [Exploration Upper Stage] on an unmanned mission to validate the new stage ahead of human missions. This has been presenting NASA with a headache for some time, although it took the recent ASAP meeting to finally confirm those concerns to the public."

NASA doesn't have the funds to human-rate it, and even if they get those funds, human-rating it will likely cause SLS's schedule to slip even more, something NASA fears because they expect the commercial manned ships to be flying sooner and with increasing capability. The contrast — a delayed and unflown and very expensive SLS vs a flying and inexpensive commercial effort — will not do SLS good politically. However, if they are going to insist (properly I think) that SpaceX and Boeing human-rate their capsules and rockets, then NASA is going to have to hold the SLS to the same standard.

Scientist Union's Talks Stall Over Pay 70 70

HughPickens.com writes: The Sacramento Bee reports that the labor contract between California's state government and the 2,800 employees represented by the California Association of Professional Scientists expired this week, spotlighting yet again the long-running feud over whether the tiny union's members should earn as much as their peers in federal and local governments and private industry. "It's a challenge to keep people motivated," says Rita Hypnarowski. "We talk about retaining the best and the brightest, but I can see that's not going to happen." A recent survey by the Brown administration found that the total compensation for half of state-employed chemists is less than $8,985 per month ($5,715 in salary, plus $3,270 in benefit costs). That's 33 percent less than the median total compensation for federal chemists, nearly 13 percent less than the midpoint for local-government chemists and almost 6 percent below the private sector.

Members of the union perform a wide variety of tasks, everything from fighting food-borne illnesses to mopping up the Refugio State Beach oil spill. For example, Cassandra McQuaid left a job last year at the Department of Public Health's state-of-the-art Richmond laboratories where she tracked foodborne illnesses. It's the kind of vital, behind-the-scenes work that goes unnoticed until an E. coli outbreak makes headlines and local health officials need a crack team of scientists to unravel how it happened. "It really came down to money," says McQuaid. "I just couldn't live in the Bay Area on a state salary."

Struggling University of Phoenix Lays Off 900 121 121

An anonymous reader writes: The struggles facing for-profit colleges continue. The University of Phoenix announced poor quarterly earnings yesterday, and the institution has laid off 900 workers since September. Enrollment is down 14% since last year, and the CEO of its parent company, Apollo Education Group, says enrollment is likely to drop from 206,000 to about 150,000 next year. Apollo's stock has lost more than half its value since the beginning of the year. "Tighter regulations on for-profits and the Obama administration's push to make community college free top the list of headwinds. And non-profit universities have entered the online education space, where for-profit schools once held center stage."
The Courts

Apple Loses Ebook Price Fixing Appeal, Must Pay $450 Million 92 92

An anonymous reader writes: A federal appeals court ruled 2-1 today that Apple indeed conspired with publishers to increase ebook prices. The ruling puts Apple on the hook for the $450 million settlement reached in 2014 with lawyers and attorneys general from 33 states. The Justice Dept. contended that the price-fixing conspiracy raised the price of some e-books from the $10 standard set by Amazon to $13-$15. The one dissenting judge argued that Apple's efforts weren't anti-competitive because Amazon held 90% of the market at the time. Apple is unhappy with the ruling, but they haven't announced plans to take the case further. They said, "While we want to put this behind us, the case is about principles and values. We know we did nothing wrong back in 2010 and are assessing next steps."

Bill Gates Investing $2 Billion In Renewables 278 278

An anonymous reader writes: Bill Gates has dumped a billion dollars into renewables, and now he's ready to double down. Gates announced he will increase his investment in renewable energy technologies to $2 billion in an attempt to "bend the curve" on limiting climate change. He is focusing on risky investments that favor "breakthrough" technologies because he thinks incremental improvements to existing tech won't be enough to meet energy needs while avoiding a climate catastrophe. He says, "There's no battery technology that's even close to allowing us to take all of our energy from renewables and be able to use battery storage in order to deal not only with the 24-hour cycle but also with long periods of time where it's cloudy and you don't have sun or you don't have wind. Power is about reliability. We need to get something that works reliably." At the same time, Gates rejected calls to divest himself and his charitable foundation of investments in fossil fuel companies.

How Television Is Fighting Off the Internet 194 194

HughPickens.com writes: Michael Wolff writes in the NY Times that online-media revolutionaries once figured they could eat TV's lunch by stealing TV's business model with free content supported by advertising. But online media is now drowning in free, and internet traffic has glutted the ad market, forcing down rates. Digital publishers, from The Guardian to BuzzFeed, can stay ahead only by chasing more traffic — not loyal readers, but millions of passing eyeballs, so fleeting that advertisers naturally pay less and less for them. Meanwhile, the television industry has been steadily weaning itself off advertising — like an addict in recovery, starting a new life built on fees from cable providers and all those monthly credit-card debits from consumers. Today, half of broadcast and cable's income is non-advertising based. And since adult household members pay the cable bills, TV content has to be grown-up content: "The Sopranos," "Mad Men," "Breaking Bad," "The Wire," "The Good Wife."

So how did this tired, postwar technology seize back the crown? Television, not digital media, is mastering the model of the future: Make 'em pay. And the corollary: Make a product that they'll pay for. BuzzFeed has only its traffic to sell — and can only sell it once. Television shows can be sold again and again, with streaming now a third leg to broadcast and cable, offering a vast new market for licensing and syndication. Television is colonizing the Internet and people still spend more time watching television than they do on the Internet and more time on the Internet watching television. "The fundamental recipe for media success, in other words, is the same as it used to be," concludes Wolff, "a premium product that people pay attention to and pay money for. Credit cards, not eyeballs."

Greek Financial Crisis Is an Opportunity For Bitcoin 358 358

An anonymous reader writes: Greece's economy has been in trouble for several years, now, and a major vote next weekend will shake it up even further. The country can't pay its debts, and the upcoming referendum will decide whether they face increased austerity measures or start the process of exiting the Euro. One side effect of the crisis is that alternative currencies like Bitcoin suddenly look much more attractive as the "normal" currencies become unstable. "Tony Gallippi, the co-founder of bitcoin payment processor Bitpay, tweeted on Sunday night that he expected the price of bitcoin to rise to between $610 and $1,250 if Greece exits the Euro. The currency is currently worth $250. Part of the reason why the crisis is so tempting for proponents of the cryptocurrency is the echoes of a previous crisis in the Eurozone: the banking collapse in Cyprus in 2013, which saw that nation also impose capital controls to prevent massive outflows of currency from the panicking country. That collapse came at the same time as the first major boom in the price of bitcoin, which began the year at less than $20 and peaked at ten times that by early April – before it all came crashing down."

The Underfunded, Disorganized Plan To Save Earth From the Next Giant Asteroid 88 88

New submitter citadrianne sends a story about the beginnings of our asteroid defense efforts, and how initial concern over an asteroid strike wasn't sustained long enough to establish consistent funding: Until a few decades ago, the powers that be didn't take the threat of asteroids very seriously. This changed on March 23, 1989, when an asteroid 300 meters in diameter called 1989FC passed within half a million miles of Earth. As the New York Times put it, "In cosmic terms, it was a close call." After this arguably close brush with total annihilation, Congress asked NASA to prepare a report on the threat posed by asteroids. The 1992 document, "The Spaceguard Survey: Report of the NASA International Near-Earth-Object Detection Workshop," was, suffice it to say, rather bleak.

If a large NEO were to hit Earth, the report said, its denizens could look forward to acid rain, firestorms, and an impact winter induced by dust being thrown miles into the stratosphere. ... After reports from the National Research Council made it clear that meeting the discovery requirement outlined in the Congressional mandate was impossible given the lack of program funding, NEOO got a tenfold budget increase from 2009 to 2014. Yet it still faces a number of difficulties. A program audit released last September described the NEOO program as a one-man operation that is poorly integrated and lacking in objectives and oversight.

Philanthropy For Hackers 27 27

An anonymous reader writes: Sean Parker, co-founder of Napster and the first president of Facebook, was part of a generation of geeks who rode the dot-com boom to financial success. Over the past two decades, that population has dramatically increased, and former hackers are carving out spots as leaders of industry. In the Wall Street Journal, Parker has posted advice for how the hacker elite can approach philanthropy. He points out that they're already bringing a level of strategy and efficacy to charity work that hasn't been seen before. "These budding philanthropists want metrics and analytic tools comparable to the dashboards, like Mixpanel, that power their software products. They want to interact directly with the scientists, field workers and academics whose ideas power the philanthropic world but who have traditionally been hidden away in a backroom somewhere, shielded from their beneficiaries by so-called development officers." One thing he advises is keeping away from large charity organizations, which largely exist to keep themselves going. He also suggests getting actively involved with the political process, even if such organizations are often distasteful.

Controversial Trial of Genetically Modified Wheat Ends In Disappointment 187 187

sciencehabit writes: A controversial GM wheat trial has failed after more than £2 million of public money was spent protecting it from GM opponents. Researchers had hoped that the wheat modified to produce a warning pheromone would keep aphids away and attract their natural enemies, reducing the need for insecticides. Despite showing promise in the laboratory, the field trial failed to show any effect. “If you make a transgenic plant that produces that alarm continuously, it’s not going to work,” ecologist Marcel Dicke of Wageningen University in the Netherlands says. “You have a plant crying wolf all the time, and the bugs won’t listen to it any longer.”

Lexus Creates a Hoverboard 102 102

walterbyrd writes: Lexus has built a functional prototype of a hoverboard that hovers several centimeters off the ground. The "Slide" is for demonstration purposes only and works through magnetic levitation created by superconductors, a spokesperson says. USA Today reports: "As cool as that sounds, there are some major limitations. Since it operates magnetically, it only can hover over a steel surface. And it also only works as long as the liquid nitrogen holds out."

The Vicious Circle That Is Sending Rents Spiraling Higher 937 937

jones_supa writes: Skyrocketing rents and multiple roommates — these are the kinds of war stories you expect to hear in space-constrained cities such as New York and San Francisco. But the rental crunch has been steadily creeping inland from coastal cities and up the economic ladder. Bloomberg takes a look at the vicious cycle that keeps rents spiraling higher. People paying high rents have a harder time saving for a down payment, preventing tenants from exiting the rental market. Low vacancy rates let landlords raise rents still higher. Developers who know they can command high rents (and sales prices) are spurred to spend more to acquire developable land. Finally, higher land costs can force builders to target the higher end of the market. The interesting question is how long can this last before we reach a level that is not affordable to the majority of the demographic that is being serviced.

Elon Musk Probably Won't Be the First Martian 167 167

pacopico writes: In a new biography on him, Elon Musk goes into gory details on his plans for colonizing Mars. The author of the book subsequently decided to run those plans by Andy Weir, the author of The Martian. Weir's book is famous for its technical acumen around getting to and from The Red Planet. His conclusion is that Musk's technology, which includes the biggest rocket ever built, is feasible — but that Musk will not be the first man on Mars. The interview also hits on the future of NASA and what we need to get to Mars. Good stuff. Weir says, "My estimate is that this will happen in 2050. NASA is saying more like 2035, but I don't have faith in Congress to fund them."

Recycling Is Dying 371 371

HughPickens.com writes: Aaron C. Davis writes in the Washington Post that recycling, once a profitable business for cities and private employers alike, has become a money-sucking enterprise. Almost every recycling facility in the country is running in the red and recyclers say that more than 2,000 municipalities are paying to dispose of their recyclables instead of the other way around. "If people feel that recycling is important — and I think they do, increasingly — then we are talking about a nationwide crisis," says David Steiner, chief executive of Waste Management, the nation's largest recycler.

The problem with recylcing is that a storm of falling oil prices, a strong dollar and a weakened economy in China have sent prices for American recyclables plummeting worldwide. Trying to encourage conservation, progressive lawmakers and environmentalists have made matters worse. By pushing to increase recycling rates with bigger and bigger bins — while demanding almost no sorting by consumers — the recycling stream has become increasingly polluted and less valuable, imperiling the economics of the whole system. "We kind of got everyone thinking that recycling was free," says Bill Moore. "It's never really been free, and in fact, it's getting more expensive."

One big problem is that China doesn't want to buy our garbage anymore. In the past China had sent so many consumer goods to the United States that all the shipping containers were coming back empty. So US companies began stuffing the return-trip containers with recycled cardboard boxes, waste paper and other scrap. China could, in turn, harvest the raw materials. Everyone won. But China has launched "Operation Green Fence" — a policy to prohibit the import of unwashed post-consumer plastics and other "contaminated" waste shipments. In China, containerboard, a common packaging product from recycled American paper, is trading at just over $400 a metric ton, down from nearly $1,000 in 2010. China also needs less recycled newsprint; the last paper mill in Shanghai closed this year. "If the materials we are exporting are so contaminated that they are being rejected by those we sell to," says Valerie Androutsopoulos, "maybe it's time to take another look at dual stream recycling."

And that reliance on obsolete technology is costing taxpayers a pretty penny.

Ask Slashdot: Making Donations Count 268 268

An anonymous reader writes: As a recent college graduate I now have a job and enough money to actually buy things and donate to causes. Up until now I really haven't been paying attention to which groups are best to donate and which are scams. For example, Goodwill seems like a great organization until you dig deeper and discover they hire under privileged and disabled people only to exploit the related government handouts instead of doing it to benefit those people. What are some quality organizations to donate to? Who do you donate to and why? I'm looking for improving the poor, supporting constitutional rights, and supporting issues many Slashdotters can agree on such as net neutrality and anything against the media companies. I don't care what political group the money ends up going to. The specific case is more important than some arbitrary label. I'm also in the USA, so foreign recommendations are probably less helpful.

General Mills To Drop Artificial Ingredients In Cereal 163 163

schwit1 writes: General Mills announced Monday that it will be removing artificial colors and flavoring from its cereal products over the next two to three years. The company said that Trix and Reese's Puffs will be some of the first cereals to undergo the changes adding that cereals like Lucky Charms that have marshmallows may take longer to reformulate. They say 90 percent of their cereals will have no artificial ingredients by the end of 2016. "We've continued to listen to consumers who want to see more recognizable and familiar ingredients on the labels and challenged ourselves to remove barriers that prevent adults and children from enjoying our cereals," said Jim Murphy, president of General Mills cereal division, in a statement.
