  • The wave of the future?

    Green technology may be hot right now, but as Joe Sieber, Sc’64, can tell you, it takes some green—in the form of cold, hard cash—to bring to market even the best green energy idea. Joe has invented a way to extract energy from the waves found on any large body of water—oceans, seas, or lakes. His patented technology is simple, reliable, efficient, renewable, low-cost, and ...


  • Water Industry on the Eco Wave?

    A wave of privatization is rolling through the water industry – at the environment‘s expense? In order to provide an answer to this question, the Environmental-Rating agency oekom research AG, Munich, put a number of water supply companies and manufacturers of water appliances to the environmental test. In results published today, oekom identifies the British water supplier Severn Trent as the ...

  • TDS-3: making waves

    It is hard to imagine that an instrument weighing only 2 oz could make ripples in the water industry. The pocket-sized TDS-3 meter from HM Digital, however, is doing just that. After less than a decade on the U.S. market, this meter has become one of the most popular handheld TDS meters for water professionals. HM Digital attributes the success of this meter to its high quality, features, and the ...

  • Powering Renewable Programs: The Utility Perspective

    When considering how to build out a renewable energy portfolio, there are a lot of factors and many points of view to consider. For purposes of this narrative, we will take the point of view of the electric utility itself. Your electricity providers are quite familiar with the concept of a “smart grid.” According to the Department of Energy (DOE), a smart grid “generally refers ...

  • How to avoid the GHS Tidal Wave

    Chemical safety touches us all. It impacts the food we eat, our health and our lifestyle. Impediments to safety can endanger individuals, businesses and society in general. Common sense dictates that sound chemical management should rely on a single classification and labeling system to address specific use patterns and groups of chemicals at the national, regional and international levels. Such ...

  • Description of the Wave Rocker - Technical version -

    Untitled Document Most people think about the sea and waves as something that moves up and down and something that rushes in and out. These observations are correct, but there are many other facts ...


  • Graphene Ushers In A New Wave Of Super-Fast Electronics

    One of the proposed uses for graphene is the construction of super-fast transistors. This is due to its ability of conducting electrons at near the speed of light. In addition, graphene is flexible and strong, making it ideal for a variety of manufacturing processes. The only impediment to this is that graphene is so electronically efficient that it is considered to have no band-gap. A band-gap ...


  • Microwave UV: A New Wave of Tertiary Disinfection

    Currently UV disinfection technologies available for use in drinking water and water reuse applications typically utilize one of three types of mercury UV lamps. These three types of mercury UV lamps include low pressure, low-pressure high-output, and medium-pressure lamps. All of these lamps contain electrodes that facilitate in the generation of UV radiation. These electrodes are of delicate ...

  • Ultrasonic waves lead to liquid cavitation creation

    Theoretically liquid starts boiling when pressure in some sites of a stream decreases to pressure of its saturated steam. Actually pressure of liquid cavitation creation process depends on the physical condition of liquid. If liquid contains a large amount of the dissolved air, reduction of pressure leads to air allocation from liquid and formation of gas cavities (cavities) in ...

  • Analytical solution of a kinematic wave approximation for channel routing

    The kinematic wave approach is often used in hydrological models to describe channel and overland flow. The kinematic wave is suitable for situations where the local and convective acceleration, as well as the pressure term in the dynamic wave model is negligible with respect to the friction and body forces. This is the case when describing runoff processes in the upper parts of catchments, ...

  • Ships that harvest electrical power from ocean waves

    Electrical power generation from ocean waves is possible from ships that harvests wave energy through daily trips to offshore locations and that return back to port for the delivery of energy to the grid. Energy is stored locally on the vessel during harvesting phase and placed on the grid during periods of high demand (normally mid-day). Unlike conventional wave-power devices, the ships ...

  • Wave of CSP activity across the MENA region

    Looking beyond Saudi Arabia, the CSP Today Global Tracker highlighted a number of updates made this week that demonstrate the progression of the concentrated solar power industry in MENA. While attention has focused heavily on the Saudi Arabian solar opportunity, it should not be forgotten that there are a number of pipelines now opening for CSP companies in the Middle East.  The ...

  • Modelling runoff on ceramic tile roofs using the kinematic wave equations

    Generally, roofs are the best candidates for rainwater harvesting. In this context, the correct evaluation of the quantity and quality of runoff from roofs is essential to effectively design rainwater harvesting systems. This study aims to evaluate the performance of a kinematic wave based numerical model in simulating runoff on sloping roofs, by comparing the numerical results with the ones ...

  • WorldWaves wave energy resource assessments from the deep ocean to the coast

    Abstract WorldWaves is a global wave and wind climate package developed through EU and industry sponsorship over many years. The offshore data incorporates global hindcast and operational wave and wind data from ECMWF, validated and calibrated with independent satellite and buoy data worldwide. These data, which may comprise full directional wave spectra time series, are used as ...

  • Measurement of Shear Waves in Laboratory Specimens by Means of Piezoelectric Transducers

    The use of piezoelectric ceramics to measure shear wave velocity in laboratory soil specimens is discussed. The experimental technique and interpretative methodology are described. Both bender and flat-plate ceramic elements were employed, and each performed well. Interpretation of the shear waveforms generated with each transducer improved as the number of wavelengths between the source and ...

  • Why it`s time to get serious about wave power

    For most of us power from the sea means watching waves crashing on a beach or smashing up against a breakwater. But if you want to experience wave power at its most energetic then you need to be offshore. In fact you need to be over one hundred kilometres offshore. In February 2000, a British oceanographic research vessel sailing in the Rockall Trough, some 180Km from land, encountered the ...

  • An Initial Study of Surface Wave Inversion Using Artificial Neural Networks

    An artificial neural network is proposed as an expeditious alternative to the trial-and-error and least-squares surface wave inversion techniques that are currently available. To use an artificial neural network for surface wave inversion, synthetic dispersion curves are calculated for representative shear wave velocity profiles using a theoretical wave propagation algorithm. An artificial neural ...
