  • Framing the Brahmaputra River hydropower development: different concerns in riparian and international media reporting

    Development of the Brahmaputra River, which links China, India and Bangladesh, has been hindered by significant challenges, particularly political challenges. News reports can mirror the perceptions of political actors, but are, owing to the complexity of the issue, complicated and unstructured. We present a comparative content analysis of the overall framing in news reports of the Brahmaputra ...

  • How to make hydropower more environmentally friendly

    Hydropower provides 85 percent of the world’s renewable electricity, but comes with a hefty environmental price tag. Here’s what some are doing to fix that. Humanity got its first large-scale electricity thanks to hydropower. On Aug. 26, 1895, water flowing over Niagara Falls was diverted to spin two generators, producing electricity to manufacture aluminum and carborundum. Since ...

  • Want to Address the Driver Shortage? Get Connected.

    The reasons drivers are giving for leaving fleets and the industry are very similar to why any employee changes jobs: Pay. Respect. Problems with a supervisor. Time away from home. Lack of communication. Bad equipment. No opportunities for advancement. Or the job just isn’t what was expected. But if you look deeper you’ll see that drivers may be saying those are the reasons, but ...

  • Optimal control of reservoir release temperature through selective withdrawal intake at hydropower dam

    This study is motivated by the need to understand the temperature dynamics and warm-water temperature withdrawal. This study also recognizes the need for an environmental assessment of the proposed temperature control schemes at New Fengman Dam. An unsteady three-dimensional (3D) non-hydrostatic model is used in the present study to predict the hydrodynamics and thermal dynamics in the forebay ...

  • Harrison Ford’s Millennium Falcon Accident – Too much Force was awoken in a hydraulically powered door

    In June 2014 the actor was crushed underneath a hydraulically powered door with “the power…. comparable to the weight of a small car” according to a spokesman from the Health & Safety Executive (HSE). The company held responsible for the accident have now pleaded guilty to two health and safety breaches under the Health & Safety at Work Act 1974. The first breach is ...

  • Ocean Thermal Energy Conversion Coming To An Island Near You

    Ocean Thermal Energy (OTE) Corporation may be landlocked in Lancaster, Pennsylvania, but that isn’t stopping them from looking to the ocean for 24/7 electricity. Their primary technology is Ocean Thermal Energy Conversion (OTEC), which uses the temperature differentials in the ocean to produce steam. The steam, in turn, activates a turbine, which generates clean energy and potable water. ...

  • Understanding water-society nexus: insights from Turkey's small-scale hydropower policy

    Turkey's recent venture involving the construction of hundreds of small-scale hydropower projects is a significant trend, both in regard to its contribution to Turkey's hydroelectricity production and the social and environmental impact of these projects at the local level. Turkey's hydropower policy was premised on a conventional understanding of water driven by science, technology, and the ...

  • Idaho Water District’s new Hydroelectric project - case study

    This Irrigation District north of Twin Falls installed a new run of the river hydroelectric facility. In order to protect their new turbines, they installed this Traveling Water Screening System. The majority of debris consists of weeds, tumbleweeds, aquatic plants and urban debris. The 5 screens at this location drop debris on a 60’ long conveyor. The conveyor carries the debris to an ...

  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...

  • Understanding India-Pakistan water politics since the signing of the Indus Water Treaty

    On 19 September 1960, the Indus Water Treaty (IWT) was signed between India and Pakistan, presumably resolving the conflict of Indus water sharing. Nevertheless, over the years the conflict has re-appeared, dragging both the riparian states into confrontation. This paper explores the reasons that lead to conflict despite the Indus water sharing having already been resolved by the IWT. Analysis ...

  • Modeling future changes in the North-Estonian hydropower production by using SWAT

    Climate change is altering temperature, precipitation, and other climatic parameters, affecting sectors dependent on water resources, e.g. energy production. The purpose of this study is to analyze the possible influences of climate change on hydropower potential in North Estonia. In Estonian run-of-river hydropower plants, energy comes mainly from water volume. Thus, changes in hydropower ...

  • EC support for UK power link raises Ireland’s offshore export potential

    The European Commission (EC) announced November 18 it had given priority status to ISLES, a cluster of Irish Sea grid projects which would transmit power from proposed Irish offshore wind farms to the UK grid. There are currently five Irish offshore windfarm projects for a total 2.6 GW of capacity. The inclusion of ISLES in the EC’s list of “projects of common interest” allows ...

  • Wind Generators as Role Models

    Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling ...

  • Monitoring Hydroelectric Dam Sumps - Case study

    The Situation Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage: The hydroelectric turbines are lubricated by lubrication oils. The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils. Vehicles ...

  • Hydropower installation

    DSEP100 Mains Decoupling Relays for hydropower projects in remote locations in the Cumbrian Lake District, UK.  Old decommissioned water wheels in Ambleside, Blencathra and Langdale have been recently refurbished and brought back into use as sophisticated hydropower turbines which are now working in parallel with the grid, ...

  • Implementation strategies and a cost/benefit comparison for compliance with an environmental flow regime in a Mediterranean river affected by hydropower

    Compliance with the Water Framework Directive (WFD) of the European Union requires water managers to establish environmental flow regimes (EFR) in rivers across the continent. Few water agencies have examined the economic and social welfare impacts of implementing environmental flow requirements. We present the approach used by the Catalan Water Agency to calculate an EFR and estimate the ...

  • Side Core Pulling Mechanism

    The flanks of plastic parts are usually provided with holes or flutes. Under such conditions, side-direction forming cores must be used to form plastc parts. However, such cores must be developed into active parts so that they can be pulled out prior to the stripping of plastic parts. The mechanism for pulling out and restoring such active cores is called  ...

  • 2014 JRC Ocean Energy Status Report

    Abstract Oceans and seas have the potential to play a significant role in providing clean energy. Different technologies are currently being developed to ensure a long term contribution of ocean energy to the future energy system. Among the different ocean energy technologies, tidal and wave conversion systems are expected to contribute the most to the European energy system in the short ...

  • Earthy, solaris and atmospheric energy sources

    Earth, sun and atmosphere are the ultimate energy resources. In addition to fossil fuels, earth radiates over 45 TW geothermal energy. Sun radiates about 89 PW energy to earth's surface. Lunar gravity supplies over 100 GW tidal ocean energy. Accessible energy from geothermal, solar, tides, waves and winds is far more than our current 17 TW energy demand, yet there are new avenues like tornadoes ...
