  • Solar Thermal Action Plan for Europe

     Ten years ago, the European Commission published its White Paper on Renewables, proposing a Community Strategy and Action Plan. Since then, European Directives to promote renewables in the electricity sector and in the transport sector have been successful in kicking off substantial growth in these two sectors. However, the renewable heating and cooling (RES-H) sector has been neglected at ...

  • Solarthermal parabolic trough power plants with integrated storage capacity

    Parabolic trough power plants use concentrated direct insulation for steam generation in a Rankine cycle. The fundamentals for direct steam generation in parabolic troughs have been developed in recent years, the feasibility was successfully demonstrated at a solar powered test facility reaching steam temperatures of 400°C at a maximum pressure of 100 bar. Important components for the accelerated ...

  • Mining water from gypsum

    Water resources in the world are scarce and unevenly distributed. In deserts, the only source of drinking water is groundwater, often saline and of poor quality. In many places, the groundwater levels have dropped dangerously due to overexploitation. Gypsum deposits, that are very common in deserts, are a potential source of drinking water, a fact that is realised by very few people. Gypsum ...

  • Critical Review to Address Nanoparticles and Environment

    For a cautionary example of the paradox of innovation, look no further than asbestos, says Pratim Biswas, Ph.D. Asbestos—because of its unmatched strength, durability, and heat resistance—was long favored by the construction industry in a wide range of uses, ...


  • Thematic Issue: Nanomaterials’ Functionality

    Nanomaterials: addressing the challenges, benefiting from the opportunities Some of the deepest challenges we will face in the coming decades derive from the opportunities offered by emerging technological advances. Many of these will improve our quality of life, and develop our economies, but all will be measured against the overarching principle that we do not make some error, and harm ...

  • Total Energy Management System: Ayers Rock Resort

    Ayers Rock Resort operates in the semi-arid conditions of the Central Australian desert. Since electricity is a major component of running costs, the Resort has installed a computer based preventative maintenance monitoring system, which links all facilities at the Resort and enables tracking of energy costs by process and item of equipment. A monthly energy audit process, together with the newly ...


  • 5 ways leaders can evolve their thinking about workspaces of the future

  • Cleantech Trends that will Change Our Future

    The terms ‘ground-breaking’ or ‘game-changing’ are frequently used to describe a new technology, or to market an innovation that supposedly will change our world forever. The truth is, we seldom really know how a new technology will unfold and how, over time, it will become part of our daily lives. The personal computer, digital imaging, genetic engineering, and the ...

  • Fossil Fuel Use Pushes Carbon Dioxide Emissions into Dangerous Territory

    Increasing global emissions of carbon dioxide (CO2), a heat-trapping gas, are pushing the world into dangerous territory, closing the window of time to avert the worst consequences of higher temperatures, such as melting ice and rising seas. Since the dawn of the Industrial Revolution, carbon emissions from burning fossil fuels have grown exponentially. Despite wide agreement by governments on ...

  • Photovoltaics: Basic Design Principles and Components

    If you are thinking of generating your own electricity, you should consider a photovoltaic (PV) system—a way to generate electricity by using energy from the sun. These systems have several advantages: they are cost-effective alternatives in areas where extending a utility power line is very expensive; they have no moving parts and require little maintenance; and they produce electricity ...

  • High diversion in the Alps (Italy)

    Award winning sustainability initiatives in Val di Fiemme help keep the popular valley pristine, while providing a worldwide role model for mountainous communities.

  • Oceans of Energy

    Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...
