“...store old turbine blades kind of a euphemism for dumping, isn’t it? “
Absolutely. Why not dispose of many other things in abandoned coal mines?
I think the turbines were made as cheaply as possible for obvious reasons. Lifespan and recyclability were sacrificed.
You could not be more correct. The blades were made in Ching Chong China. So early failure was written into the spec!!! So was the Three Gorges Dam - made in China - and it will also fail in due course.
