Tesla's Household Battery: Costs, Prices, and Tradeoffs 7

Posted by timothy
from the stick-it-on-the-wall dept.
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 17

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 85

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.

SurveyMonkey's CEO Dies While Vacationing With Wife Susan Sandberg 104

McGruber writes: Dave Goldberg, the chief executive of SurveyMonkey and spouse of Facebook COO Sheryl K. Sandberg, died on Friday night. He was 47. 'We are heartbroken by this news,' Facebook said in a statement. Mark Zuckerberg, a friend of the family, said that Mr. Goldberg died while on vacation abroad with Ms. Sandberg. Goldberg built Surveymonkey into a provider of web surveys on almost every topic imaginable, with 500 employees and 25 million surveys created. News reports said it was valued at nearly $2 billion when it raised a round of funding last year.

Tesla Adds Used Models To Its Inventory, For Online Purchase 47

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 54

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.

An anonymous reader writes: Lots of places want to be 'the next Silicon Valley.' But the Valley's top historian looks back (even talks to Steve Jobs about his respect for the past!) to explain why SV is unique. While there are threats to continued dominance, she thinks its just too hard for another region to challenge SV's supremacy.
