    What about current de-icing technology used for wind turbines?

    Okay, it sounds like from the positive point of view wind power is still growing. On the other hand wind turbine manufacturers are experiencing a knockout match while wind power plants are having a hard time making money with cranes.

    What about current de-icing technology used for wind turbines?

    The maintenance of the wind turbine is too hard and expensive. they needed a crane to do all the job each time. There are a lot of people are still in this field, But the fact is,There's no money in the Wind. at least for now.

    What about current de-icing technology used for wind turbines?

    It requires multiple channels for 380V power(4 channels), if you want to add ground control units into the blade,then it requires more. transfering temp&control signals into power channels needs a network adapter. and that make things more vulnerable. yeah, that's why they're still asking...

    What about current de-icing technology used for wind turbines?

    There are products commercially available, and they have been trying to fix this already for a very long time. and there are people still trying. A lot of people were coming up with a lot of totally different ideas. The major problem is those products's life-time are shorter than the turbine...

    What about current de-icing technology used for wind turbines?

    with slip rings or brushes, it requires muiltiple channel to send power to each blade, the technology is not a problem, it's the life-time is short compared the wind turbe. since you can't just climb there then fix or replace the equipment mounted inside the blade.

    What about current de-icing technology used for wind turbines?

    Hi, russ, if you could fix this, you can be very rich. since wind turbines under winter climate is a global problem, only a few companies had this kind of experiences in this particular field. from what I know, they're not really working that good. there're documents on IEAwind websites...

    What about current de-icing technology used for wind turbines?

    I think they did have heating elements inside the blades, the only problem is after a year a two, those heating elements are broken, and unable to fix it from the ground.

    What about current de-icing technology used for wind turbines?

    I saw those giant wind turbines stopped working in winter, since winter has most wind in four seasons. so, what good comes out of that? while at least 1/4 of time in a year that the wind turbines don't generate power. and wind turbines are so expensive with limited life time around 20 years...

    A sci-fi trilogy background. real science advice needed PLEASE

    Thanks, Filip, I've just purchased that book on amazon, It's 4 times more expensive in my country. From the reader's review, it's basically almost with the same background. and the author's writing method is also similar. guess whoever had experienced the evolution of computer science would...

    Roadrunner Supercomputer to be Decomissioned

    there are some people doing some weird things with ARM chips. http://www.kickstarter.com/projects/adapteva/parallella-a-supercomputer-for-everyone?ref=category multi-threading, multi-cores, parallel, those concepts can be confusing. you could either make it multi-seats while more people...

    A sci-fi trilogy background. real science advice needed PLEASE

    Thanks for reading and helping me out, regarding to current great Sci-fi stories, such as “matrix” or “mass effect” (video game), they are basically sharing the same fundamental philosophy behind, that is, “nature random organic lives” against “Mechanism” which is created by humans or other...

    Is Earth orbiting Sun this way?

    Thanks, Despite I've asked questions inaccurate and purely in common sense,but I think I've got all the answers, For Now!

    A sci-fi trilogy background. real science advice needed PLEASE

    Actually I did weave something more than a catastrophe, there are 3 stories,the stories are deployed in 2085 or later. story 1:It's X initiative(I'll rename X to something else while officially writing), It's a supercomputer project,designed to prevent disasters,promote human lives. but one of...

    A sci-fi trilogy background. real science advice needed PLEASE

    Thank you so much, I'll get back when I'm finished reading. It seems to me that a crazy mad Daniel Jackson in StarGate serials never gets tired, you're right about there're plenty of catastrophe stories, but it's really hard to weave some original ones,but I'll try my best.
