    "SolarNetOne is a collaborative effort spanning several continents, organizations, and technical disciplines, with the goal of developing a feasible, sustainable solution for providing public and private Internet access and related services to areas that do not have the benefit of a reliable power or communications grid. With experts in open source software, photo-voltaic electricity, internet infrastructure, and true internet pioneers on the SolarNetOne team, we have endeavored to design and implement systems capable of bridging the digital divide under the most difficult of conditions, and in the most open method available."

    Metrolight, which has just received $9 million in a third round of funding from Gemini Israel Funds and Richard Branson's Virgin Fuels, has been riding a surge of demand for its high-frequency electronic ballast, a device for controlling high-intensity discharge (HID) lights--those bright lights used for illuminating department stores, large interior spaces and freeways. The system effectively provides the same amount of light as more traditional magnetic or electromagnetic systems, but requires less overall power, the company says. Additionally, the HID lights can be dimmed when no one is present or, if the light fixture is connected to the Internet, dimmed by a utility to prevent a brown-out. Some customers have seen their electric lighting and maintenance bills drop by around 50 percent, according to Metrolight.

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

smart smart grid networks

shared by Colin Bennett on 04 Feb 10 - Cached
  • 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.

  • It's been awhile since we heard anything about the HumanCar, but it looks like the Flintstones-inspired vehicle is now rapidly becoming a reality, with it finally getting a price, release date and a even slightly sleeker new look. Apparently now more specifically known as the Imagine LMV, the vehicle will appropriately be available this coming Earth Day (April 22nd), when it'll set you back a hefty $15,000 for the "base" model. For that price you'll apparently get a top speed of 30 mph from the vehicle's dual electric motors and, most importantly, "variable human power input," which should soon make you the most popular member of your car pool group. If that's not enough luxury for you, you'll also apparently be add various navigation and internet options, iPod connectivity, and various biometric devices to see just how much of a workout you're getting.

    That's why a small server-farm company called AISO.net (for "affordable Internet services online") has gone completely off the grid. Located 80 miles southeast of Los Angeles in the desert hamlet of Romoland, AISO.net has flanked its 2,000-square-foot building with two banks of ground-mounted solar panels, which generate 12 kilowatts of electricity. Batteries store the juice for nighttime operation.

    The paper itself is flawed suggesting that virtualisation can reeduce the number of servers required to 7% - enough to handle the average processing load. Webusers want instant reaction during the peak - for that you need spare capacity. Is this a surprise?

    The Internet doesn't produce belching smokestacks or toxin-spewing drainpipes. Instead, the environmental impact of the data centers that power the Web and private networks is about as visible as the electrons moving around a company's servers. But visible or not, the ecological and economic costs of those servers are massive. A report released last week by the Environmental Protection Agency estimated that U.S. data centers (collections of computers used to power businesses' and government agencies' IT infrastructures and Web sites) consumed around 61 billion kilowatt-hours in 2006 at a cost of about $4.5 billion. That's about 1.5% of total U.S. electricity consumption, more than the electricity used by American televisions, or equivalent to the output of about 15 typical power plants

The growing Internet data network plus new online and multimedia services require increasing amounts of bandwidth and better transmission technology.
