This is from a new study by Cornell Professor Lawrence M. Cathles, published in the most recent edition of the peer-reviewed journal Geochemistry, Geophysics and Geosystems. From a greenhouse point of view, it would be better to replace coal electrical facilities with nuclear plants, wind farms and solar panels, but replacing them with natural gas stations will be faster, cheaper and achieve 40 percent of the low-carbon-fast benefit. There has been a shift about 10% of US energy generation from coal to natural gas Read more » • Email to a friend • Article Search • Carnival of Space 257 The Carnival of Space 257 is up at Dear Astronomer Kentucky Space - Do you think outside the atmosphere?

Fisheries and aquaculture are also a source of income for 55 million people. Aquaculture (fish farming), which is projected to reach about 79 million tonnes, rising by 33 percent over the period 2012–2021 compared with the 3 percent growth of capture fisheries. This projected increase is not based on much genetically modified fish adoption. Increases projected to 2012 * 33% more from aquaculture * 15% more for fish overall * 80% boost from chicken (70 million to 126 million tons) * 40% boost from pork (90 million tons to 126 million tons) Capture fisheries and aquaculture supplied the world with about 148 million tonnes of fish in 2010 valued at US$217.5 billion. Production growth from aquaculture keeps outpacing population growth, and it is one of the fastest-growing animal food-producing sectors - trends that are set to continue. Fish and fishery products are among the most-traded food commodities worldwide. Following a drop in 2009, world trade in fish and fishery products has resumed its upward trend driven by sustained demand, trade liberalization policies, globalization of food systems and technological innovations. Global trade reached a record US$109 billion in 2010 and 2011 points to another high estimated at US$125 billion. Output from fisheries and aquaculture is expected to soar 33% over the next decade, reaching 172 million tons in 2021. Last year, 90.4 million tons of fish were caught while 63.6 million tons were raised – about 600 species bred in 190 countries. But the share of farm-bred fish is expected to pass the halfway mark around 2018 and reach 52% by 2021. Chicken, Fish and Pork are projected to increase through 2021 The State of World Fisheries and Aquaculture 2012 (230 pages) Read more » • Email to a friend • Article Search • Towards Spintronic Logic Devices and 1 million times computing efficiency Eurekalert - Northwestern University researchers are making progress to an entirely new logic circuit family based on magnetic semiconductor devices. The advance could lead to logic circuits up to 1 million times more power-efficient than today's. Unlike traditional integrated circuits, which consist of a collection of miniature transistors operating on a single piece of semiconductor, the so-called "spin logic circuits" utilize the quantum physics phenomenon of spin, a fundamental property of the electron. "What we've developed is a device that can be configured in a logic circuit that is capable of performing all the necessary Boolean logic and can be cascaded to develop sophisticated function units," said Bruce W. Wessels, Walter P. Murphy Professor of Materials Science and Engineering at Northwestern's McCormick School of Engineering and Applied Science and one of the paper's authors. "We are using 'spintronic' logic devices to successfully perform the same operations as a conventional CMOS circuits but with fewer devices and more computing power." The spin-logic circuits are created with magnetoresistive bipolar spin-transistors, recently patented by the researchers. A paper describing the findings, "Emitter-Coupled Spin-Transistor Logic," was presented July 5 at the International Symposium on Nanoscale Architectures held in the Netherlands.

It appears the transitions could finally be in sight. 1. EETimes - The first production semiconductor fabs to use 450-mm wafers are projected to commence operation in 2017, according to Christian Dieseldorff, a senior analyst with the fab tool vendor trade group SEMI's industry research and statistics group. In a presentation at the Semicon West tradeshow here Monday (July 9), Dieseldorff predicted that three 450-mm fabs would commence operation in 2017. By that time, the total number of IC production fabs will have declined to 441, down from 464 this year, according to Dieseldorf.

Given his current cape design, Batman could glide to a distance of about 350 meters if he were to jump from a building about 150 meters high, a group of four University of Leicester physics students found. "The problem with the glide lies in his velocity as he reaches ground level," they wrote in the university's Journal of Special Physics Topics. The velocity rises rapidly to a maximum of a little over 110km/hr before steadying to a constant speed of around 80km/hr. Batman's wingspan, at 4.7 meters, is about half that of a hang glider. The scientists conclude that the crusader get a bigger cape, pack a parachute, or use propulsion jets to keep himself aloft. In the movie, Batman had special material that would become rigid with an electrical current. So packing a bigger cape glider could be possible with thinner cape material. In reality, the most compact designs would involve inflatable wings, but they have to be made more compact and need replacements for the metal struts.

The new technology is the heat exchanger and pre-cooler. Everything would be proven technology. The SABRE engine is capable of operating as a jet engine and a rocket engine, powering aircraft at up to five times the speed of sound within the atmosphere or directly into Earth orbit at twenty-five times the speed of sound. Its ground-breaking technology – an air pre-cooler - is designed to cool continuously the incoming airstream from over 1,000⁰C to minus 150⁰C in less than 1/100th of a second (six times faster than the blink of an eye), effectively doubling the current technical limits of jet engine speeds. Developed by Reaction Engines over the last 22 years, SABRE (Synergetic Air-Breathing Rocket Engine) is a new engine class that can operate in both air-breathing and rocket modes. This advanced combined cycle air-breathing SABRE rocket engine enables aircraft to operate easily at speeds of up to five times the speed of sound or fly directly into Earth orbit. With the pre-cooler heat exchanger and other SABRE engine advanced technology development programmes nearly completed, the next stage of the SABRE programme will include a full engine demonstrator. SABRE-powered reusable space planes like SKYLON will dramatically cut the cost of launching satellites by as much as 100 times. The global space market is worth £180 billion annually – £7.5 billion to the UK alone. This means the development of these vehicles offers major economic opportunities to the UK. It is estimated that the development stage for SABRE and the SKYLON satellite launcher alone will see investment of £7.5 billion, creating 70,000 jobs. Reaction Engines heat exchangers are 100 times lighter than current technology allowing them to be used in weight-critical aerospace applications. This is achieved through the use of extremely thin walls to separate the hot and cold fluids within the heat exchangers, coupled with advanced manufacturing techniques needed to bond these fine structures whilst maintaining their strength, durability and low weight. For example, REL has made the tube walls for its Pre-cooler as thin as possible - in our most recent demonstration the tube walls were only 27 microns thick but are bonded together to resist pressures greater than 150 bar - that's 150 times greater than atmospheric pressure at temperatures ranging from over 1,000°C to less than minus 150°C .
