  •  
    The significance of the thermal stratification for the energy efficiency of small solar thermal hot water heat stores is pointed out. Exemplary the thermal stratification build-up with devices already marketed as well as with devices still in development has been investigated experimentally and theoretically, taking into account different realistic operation conditions.

Industry News - The IET - 0 views

  •  
    Transport group Arriva is trialling B20 biodiesel - a blend of normal and plant-derived diesel - for the first time on its buses. The 75 buses in the innovative trial will run from Arriva's Blyth Garage in Northumberland and carry around 130,000 passengers every week. Minimal engineering changes will be required to the fleet as part of the scheme. The company is aiming to reduce total carbon emissions by around 14 per cent by using Fatty Acid Methyl Ester (FAME) as a 20 per cent blend. The FAME will predominantly be a mixture of sustainable soya products, along with used cooking oil and tallow.

    The E-Flight design team plan to build 10 battery "safe boxes" that will hold 8 Li-Poly battery packs per box. Initially for safety purposes, the battery packs must be charged individually but the long-term goal is to develop a single-plug charging system that could remain in the aircraft at all times.

These boots are made for electricity | Tech news blog - CNET News.com - 0 views

  •  
    MIT students James Graham and Thaddeus Jusczyk won first place with the "Crowd Farm," a proposal to produce electricity through stomping feet at the Holcim Foundation Sustainable Construction competition in Japan. Sit and step for power (Credit: MIT)The idea is that the floor would contain a sub-floor made up of several blocks that would slightly depress when someone stepped on it.

Solar powered servers for the masses | Tech news blog - CNET News.com - 0 views

  •  
    Next week, Greenest Host in San Diego is going to start offering carbon-free Web services to consumers. The company plans to start selling Web hosting services for about $14.95 a month. The trick is that its servers and other systems are powered by solar panels or batteries charged by solar panels. In rare instances, a propane-based generator will kick in, but for the most part the services will not contribute greenhouse gases into the atmosphere.

Blue Blue and solar | Tech news blog - CNET News.com - 0 views

  •  
    What do BP, Sharp and Sanyo all have in common? They are all among the largest producers of solar modules. And recently Honda and Applied Materials have entered the solar business as well. If you are a renewable energy fan, you have to get excited when large semiconductor equipment experts like Applied Materials get in the game. But the most recent prospective entrant (which I have blogged about) is IBM.

2006 Wind Installations Offset More Than 40 Million Tons of CO2 | Worldwatch Institute - 0 views

  •  
    The 15,200 megawatts of new wind turbines installed worldwide last year will generate enough clean electricity annually to offset the carbon dioxide emissions of 23 average-sized U.S. coal-fired power plants, according to a new Vital Signs Update from the Worldwatch Institute.[1] The 43 million tons of carbon dioxide displaced in 2006 is equivalent to the emissions of 7,200 megawatts of coal-fired power plants, or nearly 8 million passenger cars.

The Ampere Strikes Back - 0 views

  • The report identifies the energy burden of this new set of products that, combined with the hoarding of old products and unwitting wastage, means that, by 2020, 'ICE age' technology will account for an extraordinary 45 per cent of electricity used in UK households. That's equivalent to 14 power stations just to power our TVs, home IT and other electronics by 2020.

    Report says 1.4% of domestic consumption will be for stand-by by 2020. Since average is 700W (UK) that is 10W. We are already there!
