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.

Google's Nexus 4, 7, 10 Strategy: Openness At All Costs 359

Posted by Soulskill
from the is-openness-with-limits-openness-at-all? dept.
MrSeb writes "There have been plenty of rumors about how the Nexus program was going to grow and change with this year's announcement. Now that we have all the details, it looks like almost none of them were right. There is no Nexus certification program, and the dream of multiple Nexus phones seems well and truly dead. What we do have is a range of device sizes with the Nexus 4, Nexus 7, and Nexus 10. However, the Nexus program has been altered in one important way: we know what Nexus means now. There can no longer be any doubt: a Nexus device is about openness first and foremost. Last year the technology sphere was busily discussing whether or not the Verizon Galaxy Nexus was a 'true' Nexus device. This year we have an answer: a Nexus controlled by a carrier is no Nexus. Rather than get in bed with Verizon, Sprint, or AT&T to produce an LTE version of the Nexus 4, we have HSPA+ only. Even the new Nexus 7 with mobile data is limited to this enhanced 3G standard. And then there's the pricing: The super high-resolution (2560×1600) Nexus 10 tablet starts at just $399; The Nexus 7 is dropping in price to $199 for a 16GB tablet; The Nexus 4 with 16GB of storage is going to sell for $349, exactly the same as the old Galaxy Nexus was until yesterday. To put this into perspective, the LG Optimus G, which the Nexus 4 is based on, sells for $550 without subsidy. Google is pushing the idea of openness with the Nexus devices, but it's not an entirely altruistic endeavor. By giving us cheap and open devices, Google is making sure it's in control — not the carriers. That's better for the consumers, but it's also better for Google."

48-Core Chips Could Redefine Mobile Devices 285

Posted by timothy
from the absolute-power dept.
CWmike writes "Intel researchers are working on a 48-core processor for smartphones and tablets, but it could be five to 10 years before it hits the market. Having a 48-core chip in a small mobile device would open up a whole new world of possibilities. 'If we're going to have this technology in five to 10 years, we could finally do things that take way too much processing power today,' said analyst Patrick Moorhead. 'This could really open up our concept of what is a computer... The phone would be smart enough to not just be a computer but it could be my computer.' Enric Herrero, a research scientist at Intel Labs in Barcelona, explained that with the prototype chip someone could, for instance, be encrypting an email while also working on other power-intensive apps at the same time — without hiccups. Same for HD video. Intel's Tanausu Ramirez said it could also boost battery life. 'The chip also can take the energy and split it up and distribute it between different applications,' he said. Justin Rattner, Intel's CTO, told Computerworld that a 48-core chip for small mobile devices could hit the market 'much sooner' than the researchers' 10-year prediction."

An Open Standard For Wireless Charging? 82

Posted by timothy
from the tall-skinny-latte-power-surcharge dept.
Charging portable devices without needing to carry a power adapter sounds handy, and it's slowly getting closer to widespread use. IPAQ2000 writes that AT&T, Google and Starbucks announced yesterday "that they have joined the Power Matters Alliance (PMA). Founded by Powermat Technologies and Procter & Gamble, the PMA's Honorary Chairman is Google's Vint Cerf – one of the fathers of the Internet — and its board now also includes AT&T, Duracell, Google and Starbucks. The U.S. Government's Energy Star and Federal Communications Commission – both PMA members — are board observers." (How does Starbucks come into it? They're "testing PMA-compatible Wireless Charging Spots in select Boston stores.")

Sweden Imports European Garbage To Power the Nation 165

Posted by Soulskill
from the quick-everybody-become-more-wasteful dept.
Hugh Pickens writes "NPR reports that Sweden's program of generating energy from garbage is wildly successful, but recently its success has also generated a surprising issue: There is simply not enough trash. Sweden has recently begun to import about eight hundred thousand tons of trash from the rest of Europe per year to use in its power plants. Sweden already brings trash from Norway and hopes to get garbage from Italy, Romania, Bulgaria and the Baltic countries. Sweden creates energy for around 250,000 homes and powers one-fifth of the district heating system. Its incineration plants offer a look into the future where countries could potentially make money off of their trash instead of dumping. Landfilling of organic materials – a highly inefficient and environmentally degrading system (PDF) — has been forbidden in Sweden since 2005 and emissions of the greenhouse gas methane from landfills has fallen dramatically (PDF). 'I hope that we instead will get the waste from Italy or from Romania or Bulgaria or the Baltic countries because they landfill a lot in these countries,' says Catarina Ostlund, a senior advisor for the country's environmental protection agency. 'They don't have any incineration plants or recycling plants, so they need to find a solution for their waste.'"

Intel 335 Series SSD Equipped With 20-nm NAND 135

Posted by Soulskill
from the that's-not-many-nanometers dept.
crookedvulture writes "The next generation of NAND has arrived. Intel's latest 335 Series SSD sports 20-nm flash chips that are 29% smaller than the previous, 25-nm generation. The NAND features a new planar cell structure with a floating, high-k/metal gate stack, a first for the flash industry. This cell structure purportedly helps the 20-nm NAND overcome cell-to-cell interference, allowing it to offer the same performance and reliability characteristics of the 25-nm stuff. The performance numbers back up that assertion, with the 335 Series matching other drives based on the same SandForce controller silicon. The 335 Series may end up costing less than the competition, though; Intel has set the suggested retail price at an aggressive $184 for the 240GB drive, which works out to just 77 cents per gigabyte."
