  • Spin Doctors: How GE’s Service-Savvy Approach Squeezes the best from a fleet of 900 Wind Turbines

    Over 150 years ago, a budding English economist named William Stanley Jevons warned that a policy of energy efficiency might not be sufficient to conserve Britain’s dwindling coal reserves. His argument, now known as the Jevons paradox, was simple: Squeeze more energy from less coal, and people will just want more coal. ...

  • Solar Light Towers for Remote Security

    Lights are the most important components of security systems. Well-lit locations are generally avoided by trespassers, because such areas can disrupt stealthy movements. The isolated nature of far-flung locations, such as military bases, mining sites, agricultural operations and manufacturing plants, can be made secure with solar perimeter lighting, coupled with other security devices. ...

  • Does Wind Turbine Blade Length Really Matter?

    Simply put: Longer wind turbine blade length means greater power production. Blades capture the wind which forces the rotation of the rotor; longer blades means more area for the wind to push against, which means greater force and rotational power. However, how much difference does blade length make overall, in comparison to other factors? There is a standard formula that can be used to apply the ...

  • Performances of natural dye–sensitised solar cells - a brief review

    Dye–sensitised solar cells (DSCs), also called as photoelectrochemical cells, have the potential of commercial viability and are the most promising photovoltaic devices among the new generation of renewable energy systems. The dye used is responsible for the light harvesting efficiency and electron injection efficiency of the DSC. Vast amount of work has been done on the performance of DSCs with ...

  • Hybrid powertrain for light aircraft

    In this paper, we evaluate the possibility of employing a hybrid powertrain to propel a light aircraft. The work suggests that the incorporation of a hybrid powertrain has little effect on fuel consumption for a light aircraft operating in a condition of straight and level cruise. However, there is a potential decrease in fuel consumption when a light aircraft operates either in climb or when ...

  • Ocean Thermal Energy conversion and the company bringing it to market: peace for our children

    Two centuries ago, U.S. President John Adams advised us of the importance of observing our world with clear eyes, “Facts are stubborn things; and whatever may be our wishes and passions, they cannot alter the state of facts and evidence.” Though there are some facts we all would rather not face, one of those unpleasant truths is that there are places in the world where the need for ...

  • Solar Energy has Little Impact on Birds

    People are not worried about the pollution coming from the renewable energy sources, because most of them do not produce significant amounts of pollution. The supplies, the process of how the supplies come to the source and the demolishing machines used to erect these renewable energy sources are the true culprits wreaking havoc environmentally. For instance, older wind turbines have a negative ...

  • Energy harvesting from suspension systems using regenerative force actuators

    In this paper, harvesting vibration energy from suspension is investigated. Theoretical values for the harvested energy are calculated. Experimental evaluation of the energy is performed using vehicle road simulation facilities. An excitation signal in the frequency range of 0.5 Hz to 20 Hz is applied to the vehicle and the harvested power is calculated. Experimental results give a maximum ...

  • Ocean exergy and energy conversion systems

    Oceans store energy in the form of currents, waves, tides, heat and salinity that can help to alleviate worldwide demand for power and the global climate change threat. They also store a considerable amount of an isotope of hydrogen (deuterium) which takes part in the most promising fusion reactions. Exergy analysis can be applied to evaluate the work potential (extractable) of a resource. This ...

  • 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 ...

  • Walki biomass cover: easy cover-up improves drying process and energy content of energy wood

    Logging residue is an inexpensive and easily accessible source of biofuel, but to improve the energy content it must first dry on the ground and after that it can be stored in piles for several months. To shelter the piles from moisture through rain, snow and ice, Walki has developed a paper-based, waterproof cover that can be chipped and burned together with the residue. The importance of ...
