Those who don't know yet, angelosphere is the local wind power shill. Last time I interacted with him he came down swinging telling me that most if not all modern wind plants do not have a gearbox, and that generators of gearboxless plants don't use neodymium. When asked for which company he was talking about, he quoted GE and Siemens.
When I pointed him towards GE's current sales brochure that is almost fully plants with gear boxes, and the GE studies that showed that they couldn't make large amounts of gearboxless plants because they're both inefficient and require extreme amounts of neodymium, he suggested that GE was in fact wrong.
He had similar bouts of insanity when forced to face reality with other users as well. I prefer to simply post this boilerplate disclamer nowadays instead of trying to engage in another attempt to hammer reality in, only to have another bout of his utter insanity thrown in my face.
