IEEE Spectrum: Phase-Change Materials Could Boost Reconfigurable Chips - 0 views

  • A technology that would allow a computer chip to change the electrical resistance of some of its own wiring could lead to more-powerful reconfigurable microchips that can quickly adapt themselves to new tasks, researchers at IBM say.

Energy Search Goes Underground -- Courant.com - 0 views

  •  
    When tremors started cracking walls and bathroom tiles in this Swiss city on the Rhine, the engineers knew they had a problem. But the 3.4 magnitude tremor on the evening of Dec. 8 was no ordinary act of nature: It had been accidentally triggered by engineers drilling deep into the Earth's crust to tap its inner heat and thus break new ground -- literally -- in the world's search for new sources of energy.

BSRIA Press & Information > How many politicians does it take to change a lightbulb? - 0 views

  • The limited market penetration suggests that ignoring the differences and claiming universal compatibility will lead to consumer rejection. Politicians should develop the power of persuasion rather than the imposition of regulation.
  • In new dwellings domestic lighting suffers from inadequate installation. The formula is based upon the minimum number of lighting points arranged with the shortest cable runs. Consequently, lighting is often wrongly positioned and poorly controlled.
  • For some rooms, where there are fixed working positions such as kitchen and bathrooms, permanent lighting can be installed. For other rooms the lighting needs are determined by the layout of furnishings particular to a set of occupants. A more flexible arrangement is needed if the lighting is to both effective and efficient.

  • Finally, by removing the GLS cash-cow from tungsten filament manufacturing may cause other lamps to cease production, as it would no longer be viable to manufacture materials such as glass bulbs, drawn tungsten wire and even bayonet lamp-caps.

  • В среде энергетиков мнения об энергосберегающих лампах еще более противоречивы. Информационный ресурс сообщества профессионалов в области устойчивого развития энергетики и энергосбережения Leonardo Energy.ru поместил перевод статьи Стефана Фассбиндера из Института меди Германии, в которой эксперт подробно и доходчиво разбирает все плюсы и минусы энергосберегающих ламп. Так вот, в числе первых - естественно уже упоминаемая энергоэффективность и больший срок службы - в 5-10 раз. Однако работают эти плюсы при определенных условиях. Частое включение-выключение сокращает срок службы КЛЛ: если для лампы накаливания оправданно выключение даже на одну минуту, то КЛЛ после выключения должна постоять в бездействии, по крайней мере, 15 минут. Есть беспокойство по поводу того, что гармоники, создаваемые компактными флуоресцентными лампами, значительно ухудшают качество электроэнергии в сети. Другим побочным эффектом, с которым реально может столкнуться потребитель в жилом помещении - появление гула в громкоговорителях музыкальной системы. В местах, где свет редко включается редко, экономия будет незаметной. Кроме того, если температура окружающего воздуха крайне низкая, то экономная лампа не может достичь оптимального свечения даже после работы в течение некоторого времени. "Любая "ковровая" замена ламп накаливания представляется непродуктивной, - полагает Стефан Фассбиндер, - выборочный запрет также обречен на неудачу из-за возникающих технических проблем и трудности согласования по вопросу, где же провести границу. Переход должен быть делом свободного и обдуманного выбора, и этот процесс уже идет. Что необходимо для его продолжения - это обсуждение возникающих проблем сначала в среде специалистов, а затем с привлечением конечного потребителя".

Pan-African News Wire: China Plans Industrial System of Low-Carbon Emissions - 0 views

  •  
    "BEIJING--CHINA will build an "industrial system" and "consumption pattern" with low carbon emissions, Premier Wen Jiabao said in the government work report delivered at the parliament's annual session yesterday. The country will work hard to develop low-carbon technologies as well as new and renewable energy resources to actively respond to climate change, Wen said at the session of the National People's Congress, adding that the development of smart power grids should be intensified.

Nanomaterial Being Produced By the Ton - 0 views

  • Graphene is an extremely low density material, almost an atomic-scale chicken wire made of carbon atoms and their bonds. It has been the focus of much research because of its exceptional electrical, mechanical and optical properties. It holds great promise in renewable energies. Among the so far underutilized advantages Graphene offers are that it is fifty times stronger than steel, and it has five times the conductivity of copper, with only one quarter of the density.
  •  
    Because of its light weight Graphene is the ideal substitute for copper for aerospace defense against emerging weapons technologies such as electromagnetic pulse as well as lightning strike protection for the aerospace market.

Q&A: Bill Gates on the World's Energy Crisis | Magazine - 5 views

  • You could have the government throw money at the most politically favored guy in the country to go build a battery factory. And there are billions of dollars that have been assigned to that waste. Or you could actually back people who have better battery ideas.
  • We’re putting 90 percent of the subsidies in deployment—this is true in Europe and the United States—not in R&D. And so unfortunately you get technologies that, no matter how much of them you buy, there’s no path to being economical. You need fundamental breakthroughs, which come more out of basic research.

10 Best Apocalyptic Vehicles - 0 views

  • Global warming. Faltering economies. Dwindling resources. Mankind has finally set in motion environmental, political and social policies that will surely destroy the world as we know it. Not everyone will fall. Those who survive will roam the scorched wasteland to fend for themselves against the predatory undead while scavenging what they can to survive. The end of days is at hand, and the only question is this: What will you drive when it all comes tumbling down?

Electricity 2.0: Smart grid will bring internet-like energy revolution - 0 views

  • Not surprisingly, this intelligent, interconnected network is by no means a straightforward proposition. It has a lengthy ingredients list, and so requires extensive deployments to make it work: The most obvious component is the smart meter, which stores detailed data on energy usage and transmits and receives information, acting as the communications “gateway” into the home. On top of this, a new communications network needs to be built. Operating in parallel with the electricity grid, this network distributes data between all elements of the new intelligent grid. In the distribution and transmission network, advanced utility sensors and control systems need to be deployed in wires and substations. Such a network then provides the sensors and controls that will improve the system’s resilience. The final element is software. This is required to present, interpret, analyse and react to the huge amount of data that will consequently be flowing through the system.
