Solar Panel Breaks "Third of a Sun" Efficiency Barrier

Zothecula writes “Embattled photovoltaic solar power manufacturer Amonix announced on Tuesday that it has broken the solar module efficiency record, becoming the first manufacturer to convert more than a third of incoming light energy into electricity – a goal once branded ‘one third of a sun’ in a Department of Energy initiative. The Amonix module clocked an efficiency rating of 33.5 percent.” Read more of this story at Slashdot.

Flexible Circuits By the Slice

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.” Read more of this story at Slashdot.

Glow-In-The-Dark Smart Highways Coming To the Netherlands In 2013

An anonymous reader writes “The Netherlands is moving forward with plans to build ‘smart’ highways that can become more easily visible in the dark or communicate weather conditions to drivers. Work will begin as early as next year. ‘Special paint will also be used to paint markers like snowflakes across the road’s surface — when temperatures fall to a certain point, these images will become visible, indicating that the surface will likely be slippery. Roosegaarde says this technology has been around for years, on things like baby food — the studio has just up-scaled it. The first few hundred meters of glow in the dark, weather-indicating road will be installed in the province of Brabant in mid-2013, followed by priority induction lanes for electric vehicles, interactive lights that switch on as cars pass and wind-powered lights within the next five years.'” Read more of this story at Slashdot.

Sweden Imports European Garbage To Power the Nation

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.'” Read more of this story at Slashdot.

Increasing Wireless Network Speed By 1000% By Replacing Packets With Algebra

MrSeb writes “A team of researchers from MIT, Caltech, Harvard, and other universities in Europe, have devised a way of boosting the performance of wireless networks by up to 10 times — without increasing transmission power, adding more base stations, or using more wireless spectrum. The researchers’ creation, coded TCP, is a novel way of transmitting data so that lost packets don’t result in higher latency or re-sent data. With coded TCP, blocks of packets are clumped together and then transformed into algebraic equations (PDF) that describe the packets. If part of the message is lost, the receiver can solve the equation to derive the missing data. The process of solving the equations is simple and linear, meaning it doesn’t require much processing on behalf of the router/smartphone/laptop. In testing, the coded TCP resulted in some dramatic improvements. MIT found that campus WiFi (2% packet loss) jumped from 1Mbps to 16Mbps. On a fast-moving train (5% packet loss), the connection speed jumped from 0.5Mbps to 13.5Mbps. Moving forward, coded TCP is expected to have huge repercussions on the performance of LTE and WiFi networks — and the technology has already been commercially licensed to several hardware makers.” Read more of this story at Slashdot.

Amazon EBS Failure Brings Down Reddit, Imgur, Others

Several readers have sent word of a significant Amazon EBS outage. Quoting: “Amazon Web Services has confirmed that its Elastic Block Storage (EBS) service is experiencing degraded service, leading sites across the Internet to experience downtime, including Reddit, Imgur and many others. AWS confirmed on its status page at 2:11 p.m. ET that it is experiencing ‘degraded performance for a small number of EBS volumes.’ It says the issue is restricted to a single Availability Zone within the US-East-1 Region, which is in Northern Virginia. AWS later reported that its Relational Database Service (Amazon RDS) and its Elastic Beanstalk application plaform also experienced failures on Monday afternoon.” Read more of this story at Slashdot.
