Less bird kills, and a relatively static visual profile (vice moving blades). To all wondering why bigger is better, is because increased size gives economy of scale in both construction and output efficiency. Bigger engines use more fuel overall, but they have higher volumetric efficiency per cubic inch of displacement. This is why big ships are powered by one or two very large motors, and not thousands of little tiny ones. The converse is true, that one monster generator can make a lot more power than a number of smaller ones, and why the one large one is less expensive per megawatt generated. - Doc Rings Fri, 01 Apr 2011 02:21:59 +0100 http://www.ecogeek.org/wind-power/3468-wind-turbine-makers-working-on-giant-offshore-turb#comment-43131 The locals will love this!!! Most communities think that wind turbines are an eyesore anyway... now make it all but visible from space and watch those complaints roll in. I think the whole ethos of renewable energies is wrong anyway... to be consistent with the decentralised distribution idea these things have to be smaller, and more numerous in order to be viable. Firstly so that each unit's production cost is reduced, and the costs and effort of maintenance are likewise minimised, but also with regard to the ideas of energy security and a consistent energy supply... if this turbine fails, it would take NASA and a huge budget to replace the enormous blade over months, not to metion the lost power as a proportion of the electricity generated for the grid invested in this one turbine. If they are made smaller and there are more of them, all these problems are solved, and they can sit happily among the community, and not glaring at them from outside... and although there will be those who say that the size of this turbine is necessary to generate the power needed, with reduced production and maintenance costs (and down time costs in the event of failure)you can make more than is required to factor for loss because the renewable quality allows us to waste surplus energy without the thought of damage to the environment as an incorporated property of renewables, which the use of finite fossil fuel generated power cannot. - Matthew Yacomine Thu, 31 Mar 2011 09:03:03 +0100 http://www.ecogeek.org/wind-power/3468-wind-turbine-makers-working-on-giant-offshore-turb#comment-43128 It seems that there's a push for us all to convert over to electric vehicles. If that's the case, there's going to be an increase in energy need. I think it's best to get that energy from hydro, wind, geothermal, and solar. I'd love to see a windmill as big as our Space Needle. It boggles the mind that one could be that big, but out along our coast it's always windy. - ZetaPhased Wed, 30 Mar 2011 23:12:28 +0100 http://www.ecogeek.org/wind-power/3468-wind-turbine-makers-working-on-giant-offshore-turb#comment-43124 A picture/graph is completely useless if I can't read it. Neither this site or the source site linked to any larger picture. How the hell am I supposed to see how large this turbine is compared to other things? - Chuck Finley Wed, 30 Mar 2011 20:00:55 +0100
