The current three blade design of utility-scale turbines achieves about 80% of the Betz limit, are relatively efficient in materials for their output, and the blades’ pitch can be adjusted to control their speed in varying conditions (eg. during storms). I wouldn’t call their design “incredibly stupid”.

I obviously don’t know the specifics of the situation, but DNR on its own doesn’t mean “stop providing medical care”. The stat tests were probably to ensure grandpa didn’t get to the point of needing resuscitation.

Edit: And I don’t mean for this to be combative, it’s just that goals of care/end of life planning conversations are hard enough for the patient, family, and care team. It’s even worse when people think that DNR means “I’m giving up on my myself/mom/dad/grandparent/etc”. Resuscitation is a pretty traumatic experience, and the person may not want to go through that if the chance of them having a good quality of life afterwards is low. Everything else is still available to them if that’s what they want.

Yeah, I’m scratching my head. I have family near there and I have no idea what they’re talking about. Maybe they’re thinking of Gary?
