  • Transformational adaptation – when climate change means business as usual is no longer possible

    1. A lesson from the past Deep in the central Sahara, a crumbling mud-brick town sits at the edge of a dry lake bed. This is the medieval town of Germa, in southwestern Libya, one of a string of settlements along the Wadi al-Ajal, a valley defined by the towering dunes of the Ubari Sand Sea to the north, and the black cliffs of the Messak Settafet plateau to the south. Germa is romantic ...

  • Thoroughly modern installers keep on industry trend

    The ErP Directive, through its various iterations since 2009, not only places high demands on the efficiency levels of a wide range of heating products, and especially hot water storage in our homes, but also on installers to communicate the benefits of greater energy efficiency to their customers. If the target to reduce energy use by 20% by 2020 is remotely realistic, not only has product ...

  • Fire Codes: A Foundation of Safety for a Rapidly Changing World

    Chief among these safety features is fire protection. There are myriad codes and regulations relating to fire safety in commercial buildings, from standards on portable fire extinguishers to the installation of stationary pumps for fire protection — the U.S.- based National Fire Protection Agency (NFPA) alone has more than 300 consensus codes that have been adopted in whole or in part ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • More Power. More Control.

    Cuyahoga County pumps value to its community through greater control, standardization and technological advancements. Cuyahoga County is the most populous county in Ohio, with nearly 1.4 million residents. Part of Greater Cleveland, the county is named after a Native American word meaning "crooked river." With more than 63% of its total area made up of water, the county strives to foster strong ...

  • Security, trust, and QoS in next-generation control and communication for large power systems

    The present communication architecture supporting control of the electric power grid makes it difficult to use the wealth of data collected at high rates in substations, retarding their use in new applications for controlling the grid. A flexible, real-time data network would make it possible to use these data for many more control and protection applications, potentially increasing the grid's ...

  • Power control strategy for grid connected permanent magnet synchronous generator of a distributed generation unit

    This paper describes the studies on the operation and control of a variable speed wave energy conversion system. The wave energy conversion system considered is oscillating–water–column (OWC) based Wells turbine driven permanent magnet synchronous generator connected to the grid by means of fully controlled frequency converter. In such systems primary aim is to achieve a low distortion, high ...

  • Controlling the power balance in an 'empty network'

    This paper presents the concept of an 'empty network' and shows how the power balance can be controlled in such a system. In this study, an 'empty network' is defined as a transmission system in which no rotating mass is present. All generators are connected to distributed systems and 'hidden' behind power electronic interfaces. One generator creates a neat 50 Hz voltage that serves as a ...

  • Agents controlling the electric power infrastructure

    The electric power grid is evolving from a centrally controlled grid with only a handful of regulated monopolies to an open, liberalised electricity market. In addition, more and more small-scale dispersed generators are deployed in distribution nets. This puts extra stress on the power grid, in an era when electricity is one of the most important commodities for economic, industrial and everyday ...

  • Permit Compliance Monitoring for the Power Generation Industry

    The Clean Air Act Amendments (CAAA) of 1990 authorized EPA to develop regulations requiring facilities to monitor the adequacy of emission control equipment and plant operations. This paper discusses the various methods available for coal-fired power plants and gas turbine installations to demonstrate a reasonable assurance of facility compliance with emission limitations, and ensure that control ...

  • First commissioned LFG power generation unit in Iran

    The first landfill gas (LFG) power generation station in Iran was officially commissioned in July 2009. This plant is located in old landfill site of Mashhad, the second largest city in Iran. This landfill has been receiving municipal solid wastes (MSW) since 1975 but the first activity for biogas extraction in this site was started in 2000. The LFG extraction system in this site is based on ...


  • Spin Ice Revolutionizing Power Source Generation

    A recent discovery has enticed physicists to begin to reorder their understanding how energy particles behave after a thrilling find where a magnetic equivalent has been found to actually be able to create a particle charge much along the same lines as electricity. Spin ice, as its known, creates single controlled bursts of charges much the same as electricity, with similar behaviors and ...
