  • A binary ACO for controlling all–electric power take off system in wave energy converters

    This paper describes a metaheuristic algorithm for controlling all–electric power take off (PTO) system of wave energy converters. It provides optimal parameter values to the controller following the instantaneously changing sea state. The output of the algorithm is used to tune the electrical control systems in the PTO system in order to provide sufficient time for the point absorber to achieve ...

  • PrimasonicsTM Audiosonic Acoustic Cleaners Employ High Energy - Low Frequency Sound Waves in a Non-Intrusive, Highly Effective and Automatic Manner to Prevent Particulate Build Up and Maintaining Material Flow

    Operation: PrimasonicsTM Audiosonic Acoustic Cleaners comprise of a Wave Generator and differing Bell Sections. Compressed air enters the Wave Generator and forces the titanium diaphragm to vibrate thus creating a base tone. The varying bell sections amplify and convert this into a particular frequency depending on the application. Sound is best described as the passage of pressure fluctuations ...


  • 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 ...

  • Research and development in ocean energy technologies

    The volatile fuel prices for electricity generation, elevated concerns about global warming and energy security has prompted countries to look for alternative energy sources. One of the alternative energy sources is ocean energy. Currently, there is few ocean energy technologies that are commercially available to harness electrical energy from ocean despite the fact that ocean covers more than ...

  • Introduction to Solar Energy

    Solar energy refers to solar radiation energy. Since the formation of the earth, organism relies on the light and heat provide by the sun to survive. But nowadays, the application of solar energy has been widely paid attentions. In recent years, an increasing numbers of people pay more attention to it not because of its characteristics of the inexhaustible, but also ...

  • Energy and war – intertwined then and now

    Given that it is the 100th anniversary of the start of the First World War, there has been a lot of focus on 1914. Whilst our own EI century seems such a small event in comparison to the Great War, it does provide an interesting context. The August 1914 issue of Petroleum Review said “The review has never taken sides politically…yet it always recognises the incalculable harm which ...

  • Introduction to some kinds of renewable energy

    Clean energy is a kind of energy which does not produce pollutants in the use procedure. It includes nuclear energy and "renewable energy". Renewable energy refers to a kind of inexhaustible energy such as hydropower, wind power, solar energy, biomass energy (biogas), water energy, and tidal energy and so on. Renewable energy doesn’t have the possibility of energy depletion, and ...

  • Energy savings: VFD versus CSV case study

    The two most common ways to produce constant pressure are Variable Frequency Drives or VFD’s, and Cycle Stop Valves or CSV’s. The end result is the same in that the system sees a steady or constant pressure, as the flow rates required vary from small to large. However, these two systems control the pump in completely different ways. Variable Frequency Drives or ...

  • Environmental impacts of ocean-energy systems: a life-cycle assessment

    Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the ...

  • Interview with Adam Penque, Lockheed Martin Energy

    Tell us more about how and why Lockheed Martin Energy is building its position in the Waste to Energy sector. As the world population swells to more than seven billion and counting, the need for sustainable waste disposal and clean energy generation is growing with it. Lockheed Martin’s bioenergy power generation systems have the potential to solve both challenges At its ...
