Tesla's Household Battery: Costs, Prices, and Tradeoffs 63

Technologist Ramez Naam (hat tip to Tyler Cowen's "Marginal Revolution" blog) has taken a look at the economics of Tesla's new wall-mounted household battery system, and concludes that it's "almost there," at least for many places in the world -- and seems to already make sense in some. From his analysis: For some parts of the US with time-of-use plans, this battery is right on the edge of being profitable. From a solar storage perspective, for most of the US, where Net Metering exists, this battery isn’t quite cheap enough. But it’s in the right ballpark. And that means a lot. Net Metering plans in the US are filling up. California’s may be full by the end of 2016 or 2017, modulo additional legal changes. That would severely impact the economics of solar. But the Tesla battery hedges against that. In the absence of Net Metering, in an expensive electricity state with lots of sun, the battery would allow solar owners to save power for the evening or night-time hours in a cost effective way. And with another factor of 2 price reduction, it would be a slam dunk economically for solar storage anywhere Net Metering was full, where rates were pushed down excessively, or where such laws didn’t exist. That is also a policy tool in debates with utilities. If they see Net Metering reductions as a tool to slow rooftop solar, they’ll be forced to confront the fact that solar owners with cheap batteries are less dependent on Net Metering. ... And the cost of batteries is plunging fast. Tesla will get that 2x price reduction within 3-5 years, if not faster.

Facebook Wants to Skip the Off-Site Links, Host News Content Directly 25

The Wall Street Journal, in a report also cited by The Next Web and others, reports that Facebook is to soon begin acting not just as a conduit for news links pasted onto users' timelines (and leading to articles hosted elsewhere) but also as a host for the articles themselves. From the WSJ article: To woo publishers, Facebook is offering to change its traditional revenue-sharing model. In one of the models under consideration, publishers would keep all of the revenue from ads they sell on Facebook-hosted news sites, the people familiar with the matter said. If Facebook sells the advertisement, it would keep roughly 30% of the revenue, as it does in many other cases. Another motivation for Facebook to give up some revenue: It hopes the faster-loading content will encourage users to spend more time on its network. It is unclear what format the ads might take, or if publishers will be able to place or measure the ads they sell within Facebook. It seems likely Facebook would want publishers to use its own advertising-technology products, such as Atlas and LiveRail, as opposed to those offered by rivals such as Google Inc.

High School Students Discover Pulsar With Widest-Known Orbit 14

Science 2.0 reports that A team of high school students analyzed data from the National Science Foundation's (NSF) Robert C. Byrd Green Bank Telescope (GBT) and discovered a never-before-seen pulsar which has the widest orbit of any around a neutron star - one among only a handful of double neutron star systems. ... This pulsar, which received the official designation PSR J1930-1852, was discovered in 2012 by Cecilia McGough, who was a student at Strasburg High School in Virginia at the time, and De'Shang Ray, who was a student at Paul Laurence Dunbar High School in Baltimore, Maryland. These students were participating in a summer Pulsar Search Collaboratory (PSC) workshop, which is an NSF-funded educational outreach program that involves interested high school students in analyzing pulsar survey data collected by the GBT. Students often spend weeks and months poring over data plots, searching for the unique signature that identifies a pulsar. Those who identify strong pulsar candidates are invited to Green Bank to work with astronomers to confirm their discovery.

Empty Landscape Looms, If Large Herbivores Continue to Die Out 108

From the BBC comes this depressing excerpt: Populations of some of the world's largest wild animals are dwindling, raising the threat of an "empty landscape", say scientists. About 60% of giant herbivores - plant-eaters - including rhinos, elephants and gorillas, are at risk of extinction, according to research. Analysis of 74 herbivore species, published in Science Advances, blamed poaching and habitat loss. A previous study of large carnivores showed similar declines. Prof William Ripple, of Oregon State University, led the research looking at herbivores weighing over 100kg, from the reindeer up to the African elephant. "This is the first time anyone has analysed all of these species as a whole," he said. "The process of declining animals is causing an empty landscape in the forest, savannah, grasslands and desert." Here's the study, published in Science Advances, on which the BBC article is based.

Tesla Adds Used Models To Its Inventory, For Online Purchase 48

Jalopnik reports that Tesla Motors Inc. has very quietly started to sell used cars online, following in the footsteps of larger car companies. Its new certified vehicle program brings down the staggering costs of one of their electric cars while still ensuring manufacturer maintenance and repairs. Most of the cars that are on Tesla’s website were previously owned by people who have since traded up to the AWD Model S. Soon, this stockpile will also include leased Teslas. Engadget adds You're limited to shopping in a handful of cities in the U.S. and Canada, but the cars come with a 4-year, 50,000-mile warranty to assuage fears that you've bought a lemon. No, the move doesn't make the company's luxury EVs much more attainable -- the best offer we've seen so far is for a $59,000 'entry' model.

Microsoft's AI Judges Age From Snapshots, With Mixed Results 59

mikejuk writes: A Microsoft Research project that lets users upload photos and estimates their age and gender has attracted more attention than expected — not all of it complimentary. The How-Old.net site demonstrates of some of the capabilities of the Face API included in Microsoft's Project Oxford that was announced at Build. It may have been expected to be a source of amusement but instead it backfired when people started to upload their own photos and discovered just how wrong its estimates could be. It demonstrates not only that machine learning has a long way to go before it's good at estimating age, but also that machine learning may not be the most politically correct way to go about answering the question 'How Old Do I look'. It might be better to employ and algorithm that built in all the rules of how to make a polite answer to that request — such as always knock a decade off the age of anyone over 28. Perhaps this particular neural network needs to learn some social skills before pronouncing how old people look. However it is capable of telling some truths — a photo of Barak Obama in 2005 gives an estimated age of 46, close to his real age of 44, but just 9 years later in 2014 the age guessing robot places him at 65. It seems that Mr President aged 20 years in less than 10 years of office.

Statues of Assange, Snowden and Manning Go Up In Berlin 141

HughPickens.com writes: RT Times reports that Alexanderplatz square in Berlin has become the stage for a provocative art piece which celebrates whistleblowers and encourages ordinary citizens to speak out. "They have lost their freedom for the truth, so they remind us how important it is to know the truth," says sculptor Davide Dormino. The life-sized statues of the three whistleblowers stand upon three chairs, as if speaking in an impromptu public meeting. Next to them is a fourth, empty chair. "The fourth chair is open to anyone here in Berlin who wants to get up and say anything they want," says the artist. Dormino, who came up with the idea together with the US journalist Charles Glass, specifically chose a classical bronze statue for his depiction – and not an installation or abstract piece – since statues are usually made of establishment figures. According to Domino while men who order others to their deaths get immortalized, those who resist are often forgotten, so "the statue pays homage to three who said no to war, to the lies that lead to war and to the intrusion into private life that helps to perpetuate war." Activists and members of Germany's Green party unveiled the life-size bronze statues on May Day.

McGruber writes: A 15 year-old Douglas County, Georgia high school student has been charged with five felonies, including burglary and arson, after sheriff's deputies caught him while responding to a 1 AM fire at Alexander High School. The boy admitted to investigators that he set fire to a computer after trying, unsuccessfully, to hack into the school computer system to change his grade on a failed test. "It's very sad and tragic. He could have very easily come to one of his counselors and asked for help," said Lt. Glenn Daniel with the Douglas County Sheriff's Department. "From what we can tell, (the student) was mad and frustrated because he could not hack into the system." Lt. Daniel said the charges could land the young man in prison for several years. The computer lab was cleaned up and re-opened in time for the start of that day's classes.

An anonymous reader writes: It appears that most pharmacies in the US are interconnected, and a breach in one leads to access to the other ones. A security advisory released [Friday] shows how a vulnerability in an online pharmacy granted access to prescription history for any US person with just their name and date of birth. From the description linked above: During the signup process, PillPack.com prompts users for their identifying information. In the end of the signup rocess, the user is shown a list of their existing prescriptions in all other pharmacies in order to make the process of transferring them to PillPack.com easier. ... To replicate this issue, an attacker would be directed to the PillPack.com website and choose the signup option. As long as the full name and the date of birth entered during signup match the target, the attacker will gain access to the target's full prescription history.
