I don't like how the article is written either... trying to make it super dramatic. I think the collapse speaks for itself. A great event to study in many regards. Like: "what happens when engineers are told to make the design cheaper?" ;)

thanks for the leads. I see some blades sets for not all that much. That's a good idea. I'll keep an eye out. Thanks!

Thanks, I'm hoping to get some dimensions and design it from scratch if possible. I will check that search out.. thank you.

note, I want this to be functional, i.e. generate power. Not for decoration. Thanks!
