Very nicely handled! I am really puzzled why people here are so against this. There's potentially really good news for a plentiful and predictable source of renewable energy with some fairly cool tech and a bunch of HNers are angry? I don't get it.
How am I against it? I'm just pointing out that 75% of the turbines needing major disruptive maintenance within 6 years is not evidence that a 0% failure rate is possible.
I'm hoping for a good renewable energy source as well but that doesn't mean I have to accept shoddy statistics.
If you made 4 loaded dice and continuously rolled them for 6 years and 1 of them consistently rolled a 6 everytime then yes, it is entirely possible.
