What does that cost just in construction costs to get it erected? I can't fathom that it would ever pay back the investment on it's own after adding in the cost of the turbine itself, transport, and the ongoing maintenance which is substantial. They have a very specialized and souped up synthetic gear oil in the gearbox and even that doesn't hold up very well to the load. They have to completely swap out the gearbox every couple of years (if they are lucky) and I don't even know how many oil changes they do at about 80 gallons apiece before they have to rebuild them. To do that requires the cranes all over again. Green and clean? LOL....</blockquote>
