NRG wind energy biomimicry

  • The carbon-fiber stalks, reinforced with resin, are about a foot wide at the base tapering to about 2 inches at the top. Each stalk will contain alternating layers of electrodes and ceramic discs made from piezoelectric material, which generates a current when put under pressure. In the case of the stalks, the discs will compress as they sway in the wind, creating a charge.
  • Based on rough estimates, said Núñez-Ameni the output would be comparable to that of a conventional wind farm covering the same area
  • After completion, a Windstalk should be able to produce as much electricity as a single wind turbine, with the advantage that output could be increased with a denser array of stalks. Density is not possible with conventional turbines, which need to be spaced about three times the rotor's diameter in order to avoid air turbulence. But Windstalks work on chaos and turbulence so they can be installed much closer together, said Núñez-Ameni.

  • Núñez-Ameni also reports that the firm is currently working on taking the Windstalk idea underwater. Called Wavestalk, the whole system would be inverted to harness energy from the flow of ocean currents and waves.

    isn't this a bit of a contradiction: on the one hand: "Based on rough estimates, said Núñez-Ameni the output would be comparable to that of a conventional wind farm covering the same area" and on the other: "After completion, a Windstalk should be able to produce as much electricity as a single wind turbine, with the advantage that output could be increased with a denser array of stalks. Density is not possible with conventional turbines, which need to be spaced about three times the rotor's diameter in order to avoid air turbulence. " still, very interesting concept!

    interesting reflections by MIT head on innovation in US
  • Christos Ampatzis on 20 Nov 11
     
    interesting, especially since in all COmmission papers US innovation is praised and changes expected are only related to China/India (for the better)... Article mixes a lot talk on innovation with numbers that I do not see necessarily connected (trade deficit, GDP growth etc.). Seems to me the real problematique behind the article is only the next planned distribution of federal funds and where they should cut...
  • Joris _ on 22 Nov 11
     
    well I understand her point. Spending cuts are only vicious short term solutions against economical downturn since growth (GDP is an interesting measure indeed) comes from innovation, research and production. Nonetheless, what she is describing is happening in EU too. So who will take the lead? I am not certain China is the one. In my view, it has not yet solved its domestic issues... and US still has more Nobel Prize than China. One thing for sure, the way it is EU is only a "wagon" of the train...

    A fifth giant planet was kicked out of the early solar system, according to computer simulations by a US-based planetary scientist. The sacrifice of this gas giant paved the way for the stable configuration of planets seen today, says David Nesvorný, who believes that the expulsion prevented Jupiter from migrating inwards and scattering the Earth and its fellow inner planets.

    Solvay announced today it has successfully commissioned its 1 MegaWatt (MW) industrial demonstration Fuel Cell at the SolVin plant in Lillo, Antwerp, Belgium. This Proton Exchange Membrane (PEM) Fuel Cell converts coproduced hydrogen (H2) in the plant into electricity and is now producing for weeks at a steady rate. The Fuel Cell has generated over 500 MWh in about 800 hours of operation, which amounts to the electricity consumption of 1370 families during the same time frame.

  • Centrality measures describe a node's importance by its position in a network. The key issue obviated is that the contribution of a node to the collective behavior is not uniquely determined by the structure of the system but it is a result of the interplay between dynamics and network structure.
  • Here, we show that dynamical influence is a centrality measure able to quantify how strongly a node's dynamical state affects the collective behavior of a system, taking explicitly into account the interplay between structure and dynamics in complex networks.
