  • The VGOT Darrieus wind turbine

    We present the actual state of development of a non-conventional new vertical-axis wind turbine. The concepts introduced here involve the constructive aspects of variable-geometry oval-trajectory (VGOT) Darrieus wind turbines. The key feature of a VGOT machine is that each blade slides over rails mounted on a wagon instead of rotating around a central vertical axis. Each wagon contains its own ...

  • Air concentrating nozzles: a promising option for wind turbines

    Although the use of wind turbines has become necessary in many parts of the world, the actual developments in wind turbines do not concern countries where the average wind speeds are low. The paper introduces a new vertical axis wind rotor using a convergent nozzle for low wind speed areas. This paper brings a detailed theoretical and practical study of air concentrating nozzle and the optimum ...

  • Finite element structural study of the VGOT wind turbine

    We analyse the implementation of the finite element method to simulate the structural behaviour of the blade-wagons of variable-geometry oval-trajectory (VGOT) Darrieus wind turbines. The key feature of a VGOT machine is that each blade, instead of rotating around a central vertical axis, slides over rails mounted on a wagon formed by a tubular reticulated structure supported by standard train ...

  • Comparative study of the performances of twisted two-bladed and three-bladed airfoil shaped H-Darrieus turbines by computational and experimental methods

    The vertical axis H-Darrieus turbines are simple in construction, self-starting, omni-directional, and self-regulating at all wind speeds. A comparative study of the performances of twisted two-bladed and three-bladed airfoil shaped H-Darrieus turbines was made. The models of the turbines were designed, fabricated, and tested in a subsonic wind tunnel. The power coefficients (C ...

  • Museum of Science – Boston - Case Study

    Each year, millions of visitors come to the Museum of Science – in Boston, only Fenway Park draws more people. This nationally-renowned center dates to the mid-1800s as a resource to teach and demonstrate how technology and science affects daily living. The museum enjoys a high-profile location along the Charles River, between Boston and Cambridge. Facilities include an IMAX theater and a 2 ...

  • Look what’s cooking in the world of renewable energy

    The solar and wind innovations that got us where we are today — and those waiting in the wings — point to a hopeful future. Inside a sprawling single-story office building in Bedford, Mass., in a secret room known as the Growth Hall, the future of solar power is cooking at more than 2,500 °F. Behind closed ...
