  • The effect of intermittent operation on a wind-powered membrane system for brackish water desalination

    Renewable energy powered membrane systems that are directly-connected must take account of both the inherent fluctuations and the intermittency of the energy resource. In order to determine the effect of intermittent operation, a membrane system was tested with variables of (i) amplitude from 60 to 300 W and (ii) length of time with no power from 0.5 to 3 min. This was performed over one hour ...

  • Integrated solar and wind energy powers oil recovery system

    Recovery of free-product petroleum at the former St. Croix Alumina (SCA) site in Kingshill on St. Croix, VI, is addressing ground-water contamination caused by past releases of fuel and refined petroleum at SCA. The oil recovery system employs wind-driven turbine compressors (WTCs), wind-driven electric generators (WEGs), and photovoltaic (PV) panels to power pneumatic and electric submersible ...

  • Sustainable power and innovation provide clean drinking water and energy

    In many areas in Kenya, access to clean drinking water is lacking. About 88% of the population must travel long distances to get to the nearest source of clean water or is forced to drink contaminated water. Children in particular suffer from waterborne diseases. Systems Provide Energy-Independent Water Treatment To try to provide a long-lasting solution for the drinking water needs ...

  • Desalination plant in Egypt runs on wind & sun

    Fortis Wind Energy (NL) and Juwi Renewable (DE) install a 100kW hybrid system in Egypt. Egypt, the land of the pyramids, is known to us for its ancient culture and the last year because of the uprisings for more democracy. Egypt is less known for its large population (83 million) lives along the Nile (only 5.5% of the surface). The rest of the country is desert. The River Nile runs into Egypt ...

  • Underwater Robots Perfect for Power Production

    Underwater exploration, fish farms, dive jobs, marine research, municipal and commercial water utilities are obvious industries for the utilization of Deep Trekker mini-ROVs and pipe crawlers. However another industry that has seen remarkable success integrating underwater inspection robots is energy production. Diverse methods of creating energy provide a number of applications which benefit ...

  • Wind-driven SVE system extracts VOCs from landfill

    An innovative soil vapor extraction (SVE) system has operated at the former Ferdula Landfill site in Frankfort, NY, for the past 10 years. The system relies on wind-driven vacuum processes rather than electrically powered air blowers to extract volatile organic compounds (VOCs) from the landfill. After a two-year trial beginning in 1998, the New York State Department of Environmental Conservation ...

  • Hydro power myths Explains why various schemes such as a pool pumps or rain gutters or pumping water to a tank will not work

    Making electricity from falling water can seem like magic, and that’s led to lots of misconceptions. Here, we’ll separate fact from fiction when it comes to what microhydro systems can and cannot do. Residential-scale microhydro-electric systems have the reputation of being the holy grail of home renewableenergy (RE) systems. While they lack some of the hype, magic, and bling of ...

  • Rising seas and powerful storms threaten global security

    Standing before the United Nations General Assembly in October 1987, Maumoon Abdul Gayoom, President of the Maldives, made an appeal representing “an endangered nation.” That year for the first time, “unusual high waves” in the Indian Ocean inundated a quarter of the urban area on the capital island of Male’, flooded farms, and washed away reclaimed land. Gayoom cited scientific evidence that ...

  • ANFIS and ANN models for the estimation of wind and wave-induced current velocities at Joeutsu-Ogata coast

    In this study, the adaptive network-based fuzzy inference system (ANFIS) and artificial neural network (ANN) were employed to estimate the wind- and wave-induced coastal current velocities. The collected data at the Joeutsu-Ogata coast of the Japan Sea were used to develop the models. In the models, significant wave height, wave period, wind direction, water depth, incident wave angle, and ...

  • Impact of the climate conditions on the purification power of Beni Messous natural lagoon

    In this study, we will establish the correlations between the climate variables and the outputs of the pollution elimination in the natural lagoon of Beni Messous, using multiple regression method. We have chosen the ascending method 'FORWARD' for the selection of these variables in each regression. After the analysis, it has been noticed that the elimination output of the biochemical oxygen ...

  • The electricity–water nexus: is a crisis imminent?

    Several recent studies have warned that there will be widespread water shortages in many regions of the USA in the near future largely because of high demand for water in the production of electricity. This study reviews studies addressing electricity generation and water availability and concludes that electricity production is not likely to lead to water shortages in most regions for several ...

  • Water Direct - 22301 - Case Study

    The great storm predicted for 27-28th October 2013 failed to live up to the hype and, despite heavy rain and high winds, the UK escaped the worst of the Atlantic storms. Many may have thought it was ‘business as usual’, however this was far from the truth for everyone. In parts of Colchester and surrounding villages, homes and businesses faced misery. Blocked roads meant employees ...

  • Techno-economic evaluation of water pumping windmills in India

    An attempt to develop a simple framework for techno-economic evaluation of windmills for irrigation water pumping has been made. The amounts of water delivered by five somewhat different designs of windmill pumps at different locations have been estimated. The unit cost of water delivered and unit cost of useful energy delivered by the windmills have been estimated. The monetary benefits that ...

  • Drinking Water Sources, Sanitation and Safeguarding Desalination: a critical element of water solutions for the 21st century

    In the face of climate change and the water needs from a growing world population, the use of seawater or brackish water through desalination has increased in importance. The energy efficiency and production costs for desalination plants have been markedly improved. Recent techniques have made it possible to acquire reasonably cheap desalinated water from plants that are fully powered from wind ...
