Tesla's Household Battery: Costs, Prices, and Tradeoffs 159

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.

Why Our Antiquated Power Grid Needs Battery Storage 329

from the investing-in-wires-is-boring-but-necessary dept.
Lucas123 writes: Last year, renewable energy sources accounted for half of new installed electric-generation capacity (natural gas units made up most of the remainder). As more photovoltaic panels are installed on rooftops around the nation, an antiquated power grid is being overburdened by a bidirectional load its was never engineered to handle. The Hawaiian Electric Company, for example, said it's struggling with electricity "backflow" that could destabilize its system. Batteries for distributed renewable power has the potential to mitigate the load on the national grid by allowing a redistribution of power during peak hours. Because of this, Tesla, which is expected to announce batteries for homes and utilities on Thursday, and others are targeting a market estimated to be worth $1.2B by 2019. Along with taking up some of the load during peak load, battery capacity can be used when power isn't being generated by renewable systems, such as at night and during inclement weather. That also reduces grid demand.

Okian Warrior writes: Billionaire Elon Musk will announce next week that Tesla will begin offering battery-based energy storage for residential and commercial customers. The batteries power up overnight when energy companies typically charge less for electricity, then are used during the day to power a home. In a pilot project, Tesla has already begun offering home batteries to SolarCity (SCTY) customers, a solar power company for which Musk serves as chairman. Currently 330 U.S. households are running on Tesla's batteries in California. The batteries start at about $13,000, though California's Pacific Gas and Electric Co. (PCG) offers customers a 50% rebate. The batteries are three-feet high by 2.5-feet wide, and need to be installed at least a foot and a half off the ground. They can be controlled with a Web app and a smartphone app.

MojoKid writes: Intel has officially announced the availability of their Compute Stick HDMI dongle, and has lifted the embargo on early tests with the device. The Compute Stick is essentially a fully-functional, low-power, Atom-based system with memory, storage, and an OS, crammed into a dongle about 10cm long. There will initially be two compute sticks made available: one running Windows (model STCK1A32WFC) and another running Ubuntu (model STCK1A8LFC). The Windows 8.1 version of the Compute Stick is packing an Intel Atom Z3735F processor, with a single-channel of 2GB of DDR3L-1333 RAM and 32GB of internal storage, though out of the box only 19.2GB is usable. The Ubuntu version of the Compute Stick has as a similar CPU, but is packing only 1GB of RAM and 8GB of internal storage. All sticks have USB and MicroSD expansion capability. It doesn't burn through any benchmarks, but for multi-media playback, basic computing tasks, web browsing, HD video, or remote access, the Compute Stick has enough muscle to get the job done, and it's cheap, too: $99 — $149.

New PCIe SSDs Load Games, Apps As Fast As Old SATA Drives 162

Posted by samzenpus
from the you-don't-need-a-race-car-if-you're-just-driving-to-work dept.
crookedvulture writes Slashdot has covered a bunch of new PCI Express SSDs over the past month, and for good reason. The latest crop offers much higher sequential and random I/O rates than predecessors based on old-school Serial ATA interfaces. They're also compatible with new protocols, like NVM Express, which reduce overhead and improve scaling under demanding loads. As one might expect, these new PCIe drives destroy the competition in targeted benchmarks, hitting top speeds several times faster than even the best SATA SSDs can muster. The thing is, PCIe SSDs don't load games or common application data any faster than current incumbents—or even consumer-grade SSDs from five years ago. That's very different from the initial transition from mechanical to solid-state storage, where load times improved noticeably for just about everything. Servers and workstations can no doubt take advantage of the extra oomph that PCIe SSDs provide, but desktop users may struggle to find scenarios where PCIe SSDs offer palpable performance improvements over even budget-oriented SATA drives.

Kingston HyperX Predator SSD Takes Gumstick M.2 PCIe Drives To 1.4GB/sec 51

Posted by timothy
from the sure-hope-those-drives-appreciated-it dept.
MojoKid writes Kingston recently launched their HyperX Predator PCIe SSD that is targeted at performance-minded PC enthusiasts but is much less expensive than enterprise-class PCIe offerings that are currently in market. Kits are available in a couple of capacities and form factors at 240GB and 480GB. All of the drives adhere to the 80mm M.2 2280 "gumstick" form factor and have PCIe 2.0 x4 connections, but are sold both with and without a half-height, half-length adapter card, if you'd like to drop it into a standard PCI Express slot. At the heart of the Kingston HyperX Predator is Marvell's latest 88SS9293 controller. The Marvell 88SS9293 is paired to a gigabyte of DDR3 memory and Toshiba A19 Toggle NAND. The drives are rated for read speeds up to 1.4GB/s and writes of 1GB/s and 130 – 160K random 4K IOPS. In the benchmarks, the 480GB model put up strong numbers. At roughly $1 per GiB, the HyperX Predator is about on par with Intel's faster SSD 750, but unlike Intel's new NVMe solution, the Kingston drive will work in all legacy platforms as well, not just Z97 and X99 boards with a compatible UEFI BIOS.

FBI Accuses Researcher of Hacking Plane, Seizes Equipment 270

chicksdaddy writes: The Feds are listening, and they really can't take a joke. That's the apparent moral of security researcher Chris Roberts' legal odyssey on Wednesday, which saw him escorted off a plane in Syracuse by two FBI agents and questioned for four hours over a humorous tweet Roberts posted about his ability to hack into the cabin control systems of the Boeing 737 he was flying. Roberts (aka @sidragon1) joked that he could "start playing with EICAS messages," a reference to the Engine Indicating and Crew Alerting System.

Roberts was traveling to Syracuse to give a presentation. He said local law enforcement and FBI agents boarded the plane on the tarmac and escorted him off. He was questioned for four hours, with officers alleging they had evidence he had tampered with in-flight systems on an earlier leg of his flight from Colorado to Chicago. Roberts said the agents questioned him about his tweet and whether he tampered with the systems on the United flight -something he denies doing. Roberts had been approached earlier by the Denver office of the FBI which warned him away from further research on airplanes. The FBI was also looking to approach airplane makers Boeing and Airbus and wanted him to rebuild a virtualized environment he built to test airplane vulnerabilities to verify what he was saying.

Roberts refused, and the FBI seized his encrypted laptop and storage devices and has yet to return them, he said. The agents said they wished to do a forensic analysis of his laptop. Roberts said he declined to provide that information and requested a warrant to search his equipment. As of Friday, Roberts said he has not received a warrant.

MojoKid writes: Samsung has just announced its new SM951-NVMe SSD, the industry's first NVMe SSD to employ an M.2 form-factor. Samsung says the new gumstick style drive is capable of sequential read and write speeds of 2,260 MB/sec and 1,600 MB/sec respectively. Comparable SATA-based M.2 SSDs typically can only push read/write speeds of 540 MB/sec and 500 MB/sec, while most standard PCIe versions muster just north of 1GB/sec. The Samsung SM951-NVMe's performance is actually very comparable to the Intel SSD 750 Series PCIe x4 card but should help kick notebook performance up a notch in this common platform configuration.

Ask Slashdot: Best Medium For Storing Data To Survive a Fire (or Other Disaster) 446

Posted by samzenpus
from the burning-down-the-house dept.
First time accepted submitter aka_bigred writes Every year as I file my taxes, I replicate my most important financial data (a couple GB of data) to store an offline copy in my fire-rated home safe. This gets me thinking about what the most reliable data media would be to keep in my fire-rated home safe.

CDs/DVDs/tapes could easily melt or warp rendering them useless, so I'm very hesitant to use them. I've seen more exotic solutions that let you print your digital data to paper an optically re-import it later should you ever need it, but it seems overly cumbersome and error prone should it be damaged or fire scorched. That leaves my best options being either a classic magnetic platter drive, or some sort of solid state storage, like SD cards, USB flash drives, or a small SSD. The problem is, I can't decide which would survive better if ever exposed to extreme temperatures, or water damage should my house burn down.

Most people would just suggest to store it in "the cloud", but I'm naturally averse to doing so because that means someone else is responsible for my data and I could lose it to hackers, the entity going out of business, etc. Once it leaves my home, I no longer fully control it, which is unacceptable. My thought being "they can't hack/steal what they can't physically access." What medium do other Slashdot users use to store their most important data (under say 5GB worth) in an at-home safe to protect it from fire?

The Myth of Going Off the Power Grid 281

Posted by Soulskill
from the tell-that-to-my-hamster-wheel-colony dept.
Lasrick writes: Dawn Stover uses Elon Musk's announcement that Tesla will soon be unveiling plans for a battery that could power your home as a starting point to explore the idea that "going off the grid" is going to solve climate change. "The kind of in-house energy storage he is proposing could help make renewables a bigger part of the global supply. But headlines announcing that a Tesla battery 'could take your home off the grid' spread misconceptions about what it takes to be self-sufficient — and stop global warming." Stover worries that shifting responsibility for solutions to climate change from governments to individuals creates an 'every-man-for-himself' culture that actually works against energy solutions and does little to reduce overall greenhouse gas emissions. Instead, "smart grid" technology would be much more efficient: "With a smarter grid, excess electricity generated by solar panels and wind turbines could be distributed to a network of on-the-grid home and car batteries. Some utilities have also experimented with using home water heaters as an economical substitute for batteries."

It's powered by a quad-core Intel Atom Z3580 processor with 2GB of RAM, 16GB of internal storage, and a 2560x1600 10-inch display. You'll also find a microSD slot that supports up to 512GB of additional storage, 802.11ac, Bluetooth 4.0, Miracast, front-facing stereo speakers, a 2MP front-facing camera, and an 8MP Intel RealSense 3D camera on the rear. Where things get more interesting, perhaps, is with the design of the tablet. Whereas the Venue 8 7000 features a more traditional tablet form-factor, the Venue 10 7000 features a cylindrical "barrel edge" which Dell says makes the tablet easier to hold and carry. It's reminiscent of Lenovo's Android-powered Yoga Tablet family. In addition to providing a handy place for your hand to grip the tablet, the cylindrical spine also serves as an attachment point for an optional keyboard that transforms the Venue 10 7000 into a laptop. The keyboard accessory allows the tablet to be used in five different configurations: Tablet Mode (w/o keyboard), Tablet Mode (w/ keyboard), Laptop Mode, Tablet Stand Mode, and Tent Mode.

"Aluminum has long been an attractive material for batteries, mainly because of its low cost, low flammability and high-charge storage capacity. For decades, researchers have tried unsuccessfully to develop a commercially viable aluminum-ion battery. A key challenge has been finding materials capable of producing sufficient voltage after repeated cycles of charging and discharging. ... For the experimental battery, the Stanford team placed the aluminum anode and graphite cathode, along with an ionic liquid electrolyte, inside a flexible, polymer-coated pouch." The researchers' main challenges now are getting the battery to produce a higher voltage and store energy at a higher densities.

from the good-kind-of-race-for-the-bottom dept.
MojoKid writes Today, Intel took the wraps off new NVMe PCI Express Solid State Drives, which are the first products with these high speed interfaces, that the company has launched specifically for the enthusiast computing and workstation market. Historically, Intel's PCI Express-based offerings, like the SSD DC P3700 Series, have been targeted for datacenter or enterprise applications, with price tags to match. However, the Intel SSD 750 Series PCI Express SSD, though based on the same custom NVMe controller technology as the company's expensive P3700 drive, will drop in at less than a dollar per GiB, while offering performance almost on par with its enterprise-class sibling. Available in 400GB and 1.2TB capacities, the Intel SSD 750 is able to hit peak read and write bandwidth numbers of 2.4GB/sec and 1.2GB/sec, respectively. In the benchmarks, it takes many of the top PCIe SSD cards to task easily and at $389 for a 400GB model, you won't have to sell an organ to afford one.
