<br />
<br />
<br />
"Cuando los seres humanos hablamos de “cultura” nos referimos, en un sentido amplio, a la transmisión de los conocimientos adquiridos entre individuos de una misma especie. Pues bien, los cuervos ofrecen evidentes muestras de esta transmisión puesto que los “descubrimientos” realizados por algunos de ellos pasan de unos a otros en una clara prueba de conducta social y cultural.<br />
El ejemplo más fascinante de estas conductas, adquiridas recientemente y trasmitidas de unos a otros, lo encontramos en Japón donde los cuervos han aprendido que las ruedas de los coches pueden ser una eficaz herramienta para romper nueces. Se sitúan encima de los semáforos y lanzan sus frutos secos para que los vehículos hagan el trabajo duro por ellos."<br />

<blockquote>
Could Concentrating Solar Power Save Humanity? CSP technology has been called “the technology that will save humanity.” While that may be a grand statement, <strong>CSP could meet up to 7% of the world’s projected electricity needs in 2030, and 25% by 2050</strong>, according to CAP. California’s SEGS power plants were the first to demonstrate utility-scale CSP power starting in the 1980′s, and currently produce 310 megawatts (MW) of electricity at 5.57 cents per kilowatt hour (kWh) – enough to cheaply power 250,000 homes. In addition, Arizona’s Solana plant and California’s Ivanpah project will soon come online and produce more than 600MW of reliable power.</blockquote>
<blockquote>
Unlike solar photovoltaic or wind generation, <strong>CSP electricity is generated by heat</strong>, meaning <strong>excess output can be stored for later use and relied upon by grid operators without intermittency concerns</strong>. Storing heat energy is also 20 to 100 times more cost-effective than storing electricity in batteries, with energy-conversion efficiencies already exceeding 90%</blockquote>

<blockquote>
The electricity from our sockets could soon come from a high-tech device flying in the sky. The innovative research project to generate wind energy with the aid of a kite won over the "Venture Kick" jury; it is providing CHF 10,000 of support for the Empa spin-off "TwingTec". A kite, a reel and a console. These are the components of a pioneering new method for generating energy. The research and development project being carried out by Empa, the University of Applied Sciences Northwest Switzerland, the <a href="http://www.ethz.ch/index_EN" target="_blank" title="Federal Institute of Technology in Zurich">Federal Institute of Technology in Zurich</a> (ETH Zurich) and the <a href="http://www.epfl.ch/index.en.html" target="_blank">Federal Institute of Technology in Lausanne</a> (EPFL), combines the basic concept of a kite with innovative technology.</blockquote>
<blockquote>
<strong>The aim: to make electricity from the wind.</strong> That in itself is nothing new; electricity is already being produced by wind turbines, yet these only reach heights of around 100 metres. With the "Twing" from Empa, stronger and more regular wind currents at up to three hundred metres are "tapped".

Un grupo de trabajo de la Universidad de Delft esta generando electricidad a partir de una cometa. Lo han estado probando es la isla de Texel. En el video se puede ver como lanzan la cometa diferentes veces una vez desde tierra y dos ayudados por un dirigible. Las pruebas son parte del proyecto Laddermill de Wubbo Ockels, que proyecta producir electricidad de mánera más eficiente que con los tradicionales molinos de viento.<br />

A workgroup of the university of Delft is creating electricity with a kite. They were testing on the Dutch island Texel. You see several launches of the kite, one from the ground and two with the help of a blimp. The tests are part of the 'Laddermill' project by Wubbo Ockels, which aims to create energy from wind more efficiently than windmills.<br />

<blockquote>
When it comes to computing, the "cloud" may rain efficiency benefits. Researchers at Lawrence Berkeley National Laboratory and Northwestern University unveiled a modeling tool yesterday that estimates the energy savings of moving your digital life -- your photos, videos, emails and documents -- off your phones and desktops and into the server farms that make up the cloud. The tool, available to the public online, is called the <b><a href="http://energy-model.lbl.gov/" target="_blank">Cloud Energy and Emissions Research Model</a> (CLEER)</b>. It aims to give scientists a better understanding of how energy use changes as the world moves away from storing and processing information in individual phones, laptops and workstations and moves toward outsourcing these tasks to centralized facilities.</blockquote>

<blockquote>
Late last Friday, grid operator <a href="http://www.caiso.com/Pages/default.aspx" target="_blank">California ISO</a> (Cal-ISO) announced the state set an all-time solar record just before 1:00 pm when it registered <strong>2,071 megawatts (MW) worth of solar electricity </strong>system-wide.</blockquote>
<blockquote>
This record equaled <strong>5% of Friday’s peak demand of 36,000 MW,</strong> was enough to power <strong>1.5 million average California households</strong>, and is just under the 2,250MW of nuclear power removed from the state grid when the San Onofre Nuclear Generation Station was retired. Even more remarkable, Friday’s output doubled the record set in September 2012 when solar peaked at 1,000 MW total generation.</blockquote>

<blockquote>
Renewable energy investments are shifting to developing nations as countries from Morocco to Chile pursue power sources that wean them off fossil fuel imports, two studies promoted by the United Nations said. China’s $67 billion of investment in wind, solar and other renewable projects led developing nations to $112 billion of spending in 2012, according to an e-mailed statement today from the UN and other groups involved in the studies. That compares with $132 billion of expenditure in the industrialized world.</blockquote>
<blockquote>
<strong>The gap on renewables spending between richer and developing countries shrank to 18 percent last year from 250 percent in 2007,</strong> marking a “dramatic change” in investment patterns, the statement said. Two-thirds of the 138 nations that now have clean-energy targets are in the developing world.</blockquote>

<blockquote>
The U.S. Department of Energy has just unveiled a floating off-shore wind platform that it thinks could make a big splash.</blockquote>
<blockquote>
But it has already been working hard to commercialize “<strong>tidal energy</strong>” that uses <strong>underwater turbines to create electricity</strong>, which must then be wired into the grid.</blockquote>
<blockquote>
Wave and tidal facilities are being tested. One such “wave” project has begun off the shores of <strong>Oregon</strong>, where <strong>underwater turbines using 10 buoys will generate 1.5 megawatts of power</strong>. Impediments to further growth are wide ranging and cover such issues as the preservation of aquatic resources, water quality and the maintenance of marine life. In the end, regulators — who are trying to diversify the nation’s energy mix with green fuels — have concluded<strong> that energy from the ocean is a valued part of the plan and that it is more predictable than wind or solar</strong>.</blockquote>

According to the Center for Science and Environment in Delhi, solar energy has finally “arrived” – it is now causing trade wars between the US, Europe and China, which tells you that this sector is growing and is lucrative (hence all the competitiveness). Today, solar energy is positioned to become a new source of power to lead the world to a low-carbon future and hopefully, away from a global climate catastrophe (caused by rising emissions from burning fossil fuels). For <b>solar energy to become so cheap that it can compete with coal and oil, its deployments needs to be greatly scaled up</b>.</blockquote>

<blockquote>
The US throws out 250 million tons of garbage a year. Roughly a third is recycled, and the rest is landfill. You might think that’s a problem. But one man’s trash is another’s treasure. Oslo, Norway burns rubbish to power and heat homes, and they’ve run out. The city imports trash from Sweden, Ireland, England—and they wouldn’t mind taking on a few tons from the US. And it’s not just Oslo. Northern Europe’s trash burning capacity outstrips its trash producing capacity by 550 million tons. Neighboring Sweden imports 800,000 tons of trash annually to make energy. Norway, Austria, and Germany are also getting in on the game. In total, 40 countries worldwide burn trash for energy.</blockquote>

<blockquote>
Tras el anuncio de la ONU del nuevo récord alcanzado en cuanto a nivel de dióxido de carbono en la atmósfera, resulta evidente la urgente necesidad de un viraje en el perfil energético existente hacia uno capaz de hacer frente al cambio climático y a asegurar un futuro más sostenible. En el caso concreto de Indonesia, con un 80% de emisiones con origen en la deforestación y el uso de la tierra, la transición se debe dirigir hacia un esquema basado en las energías renovables. El Gobierno indonesio ha mostrado su buena voluntad y predisposición para incentivar un uso energético más equilibrado en el país. En primer lugar, el presidente, Susilo Bambang, emitió la 'Regulación Presidencial 5/2006', que tiene como meta acelerar el uso de las energías 'limpias'. En septiembre de 2011 se anunció un plan de acción nacional para la reducción de las emisiones de gas (RAN-GRK), marco para integrar la mitigación del cambio climático en el desarrollo del país asiático. Además, se han adoptado medidas dirigidas a la atracción de inversores privados, a través de las cuales se establecerá un sistema de primas para la electricidad producida por las plantas solares en áreas remotas del territorio nacional. El pasado año se introdujo una disposición similar en el ámbito de la energía geotérmica. Por último, el documento 'Vision 2025' diseñado por el Ministerio de Energía y Recursos Minerales anticipa un uso de las fuentes renovables del 25% del mix energético nacinal en el horizonte de dicho año. Considerando que durante el ejercicio de 2012 el uso de las energías renovables supuso, aproximadamente, un 5% del total energético, el Consejo Nacional de Energía de Indonesia ha manifestado su "incertidumbre ante el pronóstico realizado". Sin embargo, a pesar de los avances mostrados, todavía queda un largo camino por recorrer en la transición energética de Indonesia. Entre los aspectos que deben tenerse en cuenta se encuentran la mejora en la eficiencia, tanto en materia de generación como en el ámbito de la distribución y la transmisión; la drástica reducción o eliminación de los subsidios estatales al combustible; y una clara comunicación por parte del Gobierno en referencia a la necesidad del uso de las energías renovables.</blockquote>

<blockquote>
The state’s largest power-buying consortium is entering the solar energy market, starting with four local colleges and schools that will add solar arrays to their properties. PowerOptions of Boston, which uses the buying power of the consortium to negotiate electricity and natural gas prices for nonprofit and public organizations, will partner with SunEdison, a Missouri-based solar services company. SunEdison, which will build the solar arrays over the summer, will own and maintain the installations and sell the power to the schools and colleges.</blockquote>

<blockquote>
Omán estudia la posibilidad de hacer uso de la energía renovable para satisfacer parte de su creciente demanda de electricidad. <strong>El país considera las fuentes solar y eólica como "especialmente adecuadas" para satisfacer las necesidades energéticas de las regiones más remotas y rurales del país.</strong> Rural Areas Electricity Company (RAECO) contempla el desarrollo de seis proyectos de energía renovable (cuatro iniciativas relacionadas con la energía solar y dos eólicas) como parte de su plan quinquenal 2013-2017.</blockquote>
<blockquote>
El director ejecutivo de RAECO, Hamed bin Salim al Magdheri, ha declarado que la compañía está trabajando en otros <strong>dos proyectos con aerogeneradores en Masirah y Thamrait, con una capacidad de producción de entre 200 y 300 kW</strong>.</blockquote>
<blockquote>
La entidad ultima el inicio de la puesta en marcha de un <strong>proyecto eólico de 750 kW en Al Mazyuona</strong>, así como otra acción similar en el ámbito de la <strong>energía solar (de 350 kW) en Masirah</strong>. En la actualidad, <strong>las 48 plantas operativas producen 700 MW de energía para los 26.000 clientes</strong> en las regiones del interior del país. Según el Instituto Internacional de Estudios Científicos, la ubicación de Omán es ideal para la producción de energía solar. En opinión de Al Magdheri, "es más factible la creación de proyectos de energía solar que seguir dependiendo de aquella proveniente del diésel". La electricidad en Omán cuenta con un subsidio del 70%.</blockquote>

<br />
But the bulk of the book is hands-on: the nuts-and-bolts of siting; foundations; <b>flooring; living (plant-covered) roofs; and cob, cordwood, straw-bale and modified stick frame walls</b>—although the book's minimal treatment of electricity and plumbing, and how to integrate them with unfamiliar materials like cob or straw-bale, disappoints. Snell's tendency to decry the sins of modern architectural practice can become exasperating, but doesn't diminish the value of his extensive experience-derived knowledge; and the grace and beauty of the authors' building project, featuring Callahan's fine finish work, is inspiring.<br />
<br />
The abundance of color photos detailing the construction process, supplemented by examples from indigenous buildings around the world, is particularly helpful. (Jan.)<br />
