An Efficient 60 Watt LED Bulb For Under $15 | Ecopreneurist CleanTech Published on August 30th, 2011 | by Elizabeth Smyth Yesterday, Lighting Science Group and Dixon Technologies announced one of their first joint products: A high-performance, omnidirectional 60-watt equivalent A19 LED bulb that retails for under $15. According to the company, “The newly announced bulb fits perfectly into existing screw-in light sockets and creates a clean, bright light level equivalent to a conventional 60-watt incandescent bulb using 85% less electricity.” Currently, the majority of 60W LEDs retail in the $40 range. The companies confirm this new technology will go on to power a full line of products, including street lights, outdoor and industrial light fixtures and replacement bulbs. The new LED bulb will be available in India by the end of the year and sold worldwide by early next year. Image source: Lighting Science Group / PR Newswire.LSG press release. About the Author

Working together to make our cities great | EngagingCities | the internet of things, open data and the city eco-business.com Energy production and supply units may be fined up to VND100 million (US$4,800) for administrative violations leading to the waste of energy under a new decree to become effective on October 15. The highest fine will be applied to units who purposefully do not reject obsolete technology and low-output electricity generators or those who build new generators with obsolete technology. Decree 73/2011/ND-CP regulates fines on administrative violations relating to economical and effective energy use. It applies to violations of regulations on energy audits, energy labels, production, imports and energy using devices or violations on economical and effective energy use at key energy using units. “The decree aims to guide the implementation of the law on economical and effective use of energy that came into effect at the beginning of this year,” said deputy director of the Ministry of Industry and Trade’s Science and Technology Department Phuong Hoang Kim.
online - IBM plant Massenfertigung von dreidimensionalen Prozessoren IBM will gemeinsam mit dem Technologiekonzern 3M einen neuen dreidimensionalen Prozessor mit 100 gestapelten Chips in die Massenfertigung bringen. IBM verspricht sich davon laut Mitteilung schnellere und energieeffizientere Rechner. Bislang werden die teuren Stapel-Prozessoren nur für Spezialanwendungen eingesetzt. Aufgrund der Wärmeentwicklung können mit den derzeitigen Klebstoffen aber nur bis zu zehn Ebenen übereinandergestapelt werden, ohne dass der Prozessor überhitzt und thermische Störeffekte die Rechenleistung beeinträchtigen. IBM will zudem den Fertigungsprozess erweitern. Um die Wärmeentwicklung aufgrund des Stapelns in den Griff zu bekommen, genügten aber nicht nur bessere Klebematerialien, gibt Eby Friedman, Professor für Elektrotechnik an der University of Rochester, zu bedenken.
In 2025 630 Million of Us Will Live in 37 Megacities As I was reading my morning paper today I came across a quote from Robert Friedland, an entrepreneur and mining engineer who in giving a speech to the MineAfrica event of the Prospectors and Developers Association annual conference being held in my hometown of Toronto, talked about the importance of Africa as an untapped resource for key minerals. He framed this remark around the issue of rural to urban migration accelerating in Africa and many other parts of the Developing World. What struck me about the speech was the following quote: “By 2025, which is tomorrow morning in geologic time, and at the scale in which we invest in mining, 630 million people, or 14 per cent of the world’s urban population, and 8 per cent of all the people walking on this planet, will live in 37 megacities.....As you build those cities, not only are you wildly consumptive of copper and steel and iron and molybdenum, but look at the air. The Urban Revolution is Here and it Looks Ugly
The Impacts of Energy-Smart Buildings This white paper from Microsoft, Accenture and the Lawrence Berkeley Laboratory looks at how conducting an IT retrofit of building management tools can have a quick return on investment. Microsoft, in partnership with Accenture and the Lawrence Berkeley National Laboratory, deployed smart building management systems on 2.6 million square feet of its corporate campus -- which totals 15 million square feet over 118 buildings. Through energy management, alarm management and fault detection and diagnosis, Microsoft expects to save more than $1 million per year in energy costs, with a payback time of less than 18 months. The findings of the project, which is intended in part to be a learning experience to understand the potential and limitations of current building management systems, can be put to work for almost any company. The white paper lays out some other success stories from similar projects, including:
online - Schwungräder vor der Wiedergeburt Die Fahrzeugbauer Volvo und Jaguar planen Hybridfahrzeuge, die neuartige Schwungräder statt Batterien als Energiespeicher nutzen, um die Beschleunigung zu optimieren und die Motoren insgesamt effizienter zu machen. Die Komponenten könnten den Benzinverbrauch um bis zu 20 Prozent senken, hoffen die Ingenieure. Gleichzeitig sollen die Kosten aber nur bei einem Drittel vergleichbarer Akkusätze liegen, berichtet Technology Review in seiner Online-Ausgabe. Bei einem solchen System wird die Energie der Räder genutzt, um parallel eine Schwungmasse anzutreiben, die hohe Rotationsgeschwindigkeiten erreicht. Diese dreht sich auch ohne Energiezufluss weiter und dient so als Zwischenspeicher. Die Rotationsenergie lässt sich anschließend über das Getriebe wieder an die Räder abgeben. Neu ist die Idee nicht, doch war es bislang schwer, wirklich effiziente Schwungräder zu bauen. Doch mittlerweile ist die Technik weiter fortgeschritten. Mehr zum Thema in Technology Review online:
