Volcano Power Plan Gets US Go-Ahead 114

Posted by samzenpus
from the lets-get-cooking dept.
cylonlover writes "Having successfully negotiated the challenging regulatory slopes of the U.S. Bureau of Land Management, the U.S. Forest Service, the U.S. Department of Energy, and a host of Oregon state agencies, the Newberry Enhanced Geothermal Systems (EGS) demonstration project is in the process of creating a new geothermal reservoir in central Oregon. The core of the new reservoir is a two mile (3.2 km) deep well drilled about four miles (6.4 km) from the center of Newberry Volcano. The rock surrounding the wellbore reaches temperatures in the order of 600 F (300 C), and is nearly impermeable to water. That, however, is about to change. Newberry Volcano is one of the largest and youngest volcanoes in the United States. Having last erupted about 1,300 years ago, it consists of over 400 individual volcanic vents, which, when combined, form a broad mounded landform referred to as a shield volcano. The Newberry EGS Demonstration geothermal reservoir is being formed in the high-temperature, low-permeability deep lava of the volcano's northwest flank."

Vanderbilt University Steps Into the Exoskeleton Market 26

Posted by samzenpus
from the power-up dept.
Zothecula writes "For people who are unable to walk under their own power, exoskeletons offer what is perhaps the next-best thing. The devices not only let their users stand, but they also move their legs for them, allowing them to walk. While groups such as Berkeley Bionics, NASA, Rex Bionics, and ReWalk are all working on systems, Nashville's Vanderbilt University has just announced the development of its own exoskeleton. It is claimed to offer some important advantages over its competitors."

Ask Slashdot: Little Boxes Around the Edge of the Data Center? 320

from the gee-look-at-all-the-little-black-dots dept.
First time accepted submitter spaceyhackerlady writes "We're looking at some new development, and a big question mark is the little boxes around the edge of the data center — the NTP servers, the monitoring boxes, the stuff that supports and interfaces with the Big Iron that does the real work. The last time I visited a hosting farm I saw shelves of Mac Minis, but that was five years ago. What do people like now for their little support boxes?"

To Mollify Google on Moto Patents, Apple Proposes $1/Device Fee 582

Posted by timothy
from the you-know-what-the-cartel-wants dept.
An anonymous reader writes "Motorola feels that Apple is infringing on several FRAND patents that have to do with how every smartphone in existence connects to WiFi and cellular networks. Since Apple makes smartphones, and Google is looking to use their newly acquired Motorola as a weapon, the two companies are only a few days away from the courtroom. Apple has conceded that the Moto patents are valid by offering to pay Google/Moto $1 per device, but only going forward. Motorola wants 2.25% per device and for it to cover all Apple devices (back dated). If Motorola pursues the case and the court issues a per device rate that is higher than Apple's offer, Apple promises to pursue all possible appeals to avoid paying more than $1. Motorola could end this quickly, or watch as Apple drags this out for what could be years."

Ask Slashdot: Digital Pens On Linux? 74

Posted by timothy
from the pen-envy dept.
New submitter Gonzalez_S writes "There are many digital pens out there, but none of them seem to work on Linux; unless you combine them with a tablet. I have contacted many vendors (Lifetrons, Dane-Elec, ApenUSA, IntelliPen..) and only Intellipen responded that there is very limited support for Linux. Do any of you know of a digital pen that works fine using Linux on normal paper? Some options to explore: can the pen work in real time on my PC screen? Can it function as a mouse? Can the pen work offline? Do I need a tablet (preferably not)? I would be happy if anyone shares a success story here, as they seem a great tool."

Breakthrough Promises Smartphones that Use Half the Power 110

Posted by samzenpus
from the save-the-juice dept.
Dupple writes in with news about a discovery that should extend the life of your battery in the near future. "Powering cellular base stations around the world will cost $36 billion this year—chewing through nearly 1 percent of all global electricity production. Much of this is wasted by a grossly inefficient piece of hardware: the power amplifier, a gadget that turns electricity into radio signals. The versions of amplifiers within smartphones suffer similar problems. If you've noticed your phone getting warm and rapidly draining the battery when streaming video or sending large files, blame the power amplifiers. As with the versions in base stations, these chips waste more than 65 percent of their energy—and that's why you sometimes need to charge your phone twice a day. It's currently a lab-bench technology, but if it proves itself in commercialization, which is expected to start in 2013—first targeting LTE base stations—the technology could slash base station energy use by half. Likewise, a chip-scale version of the technology, still in development, could double the battery life of smartphones."

Flexible Circuits By the Slice 10

Posted by Soulskill
from the one-is-not-enough-but-two-is-too-much dept.
MTorrice writes "Researchers have demonstrated a way to make high performance, flexible integrated circuits using almost exclusively standard equipment and materials already needed to make conventional chips. Such a method could allow electronics manufacturers to build new devices, such as smart medical implants and flexible displays, without needing to significantly overhaul current production protocols. The method, developed by researchers at the University of Texas, Austin, started with researchers patterning integrated circuits on silicon wafers using a standard production line. They then cut off the top 20 to 30 micrometers of the wafer using a thin wire—like slicing a block of cheese—to produce a thin, flexible platter of circuits."

Wireless Power Over Distance: Just a Parlor Trick? 215

Posted by Soulskill
from the efficiency-is-a-harsh-taskmaster dept.
Lucas123 writes "Companies like U.S.-based WiTricity and China-based 3DVOX Technology claim patents and products to wirelessly powering anything from many feet away — from smart phones and televisions to electric cars by using charging pads embedded in concrete. But more than one industry standards group promoting magnetic induction and short-distance resonance wireless charging say such technology is useless; Charging anything at distances greater than the diameter of a magnetic coil is an inefficient use of power. For example, Menno Treffers, chairman of the Wireless Power Consortium, says you can broadcast wireless power over six feet, but the charge received will be less than 10% of the source. WiTricity and 3DVOX, however, are fighting those claims with demonstrations showing their products are capable of resonating the majority of source power."

Linus Torvalds Advocates For 2560x1600 Standard Laptop Displays 661

Posted by Soulskill
from the at-least-catch-up-to-mid-'90s-CRT-screens dept.
beeudoublez points out a Google+ post by Linus Torvalds arguing that today's standard laptop display resolution is unreasonably low. He said, "...with even a $399 tablet doing 2560x1600 pixel displays, can we please just make that the new standard laptop resolution? Even at 11"? Please. Stop with the 'retina' crap, just call it 'reasonable resolution.' The fact that laptops stagnated ten years ago (and even regressed, in many cases) at around half that in both directions is just sad. I still don't want big luggable laptops, but that 1366x768 is so last century."

China Building a 100-petaflop Supercomputer Using Domestic Processors 154

Posted by Unknown Lamer
from the mips-vs-arm-culture-conflict dept.
concealment writes "As the U.S. launched what's expected to be the world's fastest supercomputer at 20 petaflops, China is building a machine that is intended to be five times faster when it is deployed in 2015. China's Tianhe-2 supercomputer will run at 100 petaflops (quadrillion floating-point calculations per second), according to the Guangzhou Supercomputing Center, where the machine will be housed. Tianhe-2 could help keep China competitive with the future supercomputers of other countries, as industry experts estimate machines will start reaching 1,000-petaflop performance by 2018." And, naturally, it's planned to use a domestically developed MIPS processor

Dupple writes with a quote from the BBC about more testing of Predator drones in U.S. air space: "Tests have been carried out to see whether military drones can mix safely in the air with passenger planes. The tests involved a Predator B drone fitted with radio location systems found on domestic aircraft that help them spot and avoid other planes. The tests will help to pave the way for greater use of drones in America's domestic airspace."

ARM Announces 64-Bit Cortex-A50 Architecture 160

Posted by Unknown Lamer
from the intel-to-re-release-itanic dept.
MojoKid writes "ARM debuted its new 64-bit microarchitecture today and announced the upcoming launch of a new set of Cortex processors, due in 2014. The two new chip architectures, dubbed the Cortex-A53 and Cortex-A57, are the most advanced CPUs the British company has ever built, and are integral to AMD's plans to drive dense server applications beginning in 2014. The new ARMv8 architecture adds 64-bit memory addressing, increases the number of general purpose registers to 30, and increases the size of the vector registers for NEON/SIMD operations. The Cortex-A57 and A-53 are both aimed at the mobile market. Partners that've already signed on to build ARMv8-based hardware include Samsung, AMD, Broadcom, Calxeda, and STMicro." The 64-bit ARM ISA is pretty interesting: it's more of wholesale overhaul than a set of additions to the 32-bit ISA.

Ask Slashdot: What Stands In the Way of a Truly Solar-Powered Airliner? 590

Posted by Soulskill
from the i-blame-gravity dept.
centre21 writes "I've been reading about solar-powered aircraft all over the Internet, as well as solar power in general. But I'm wondering: is it more than just solar cell efficiency that's preventing the creation of a solar-powered airliner? Conspiracy views aside (which may be valid), it seems to me that if I were running an airline the size of United or American, eliminating the need for jet fuel as a cost would be highly appealing. So, I'm asking: what stands in the way of creating true solar-powered airliners?"

New York Data Centers Battle Floods, Utility Outages 186

Posted by Soulskill
from the bunker-in-tight dept.
miller60 writes "At least three data center buildings in lower Manhattan are struggling with power problems amid widespread flooding and utility outages caused by Hurricane Sandy. Flooded basements at two sites took out diesel fuel pumps, leaving them unable to refuel generators on higher levels. One of these was Datagram, which knocked out Buzzfeed and the Gawker network of sites. At 111 8th Avenue, some tenants lost power when Equinix briefly experienced generator problems." The NY Times has a running list of Sandy-related problems, including 5,700 more flight cancellations, 6 million people without power, rising water levels at a nuclear plant, official disaster declarations from President Obama, and a death toll of 38. On the upside, and despite the high water levels, the Nuclear Energy Institute was quick to point out that all 34 nuclear facilities in Sandy's path made it through without problems.
