Looks very interesting. Didn't find a word about birds' safety on your landing page. This is even less visible to birds than traditional turbines, if I am not mistaken.

2.4 billion birds are killed by cats every year. 600 million by flying into glass panes. 200k by flying into wind turbines. (these are US statistics, so not global numbers) The bird death argument is completely meaningless in several aspects. I'd rather make cats illegal than put any kind of breaks on wind power expansion.

  Your statistics are of course true, but cats and wind turbines kill different species of birds. It does make sense not to put wind turbines where endangered birds are nesting.

    Just paint a blade black. The dazzle effect will keep birds away. https://www.bbc.com/news/science-environment-53909825.amp https://www.bbc.com/news/science-environment-53909825.amp

  I don't trust those numbers.

    Ok, then either post better ones or say why you don't like them, or what is the reason for distrust. Just saying "I don't trust these numbers" adds absolutely nothing to the discussion. Imagine if I said "I trust these numbers" - is that helpful?

      The billion birds things seems to go back to one single "study", and there already seem to be doubts about it https://www.npr.org/sections/13.7/2013/02/03/170851048/do-we-really-know-that-cats-kill-by-the-billions-not-so-fast https://www.npr.org/sections/13.7/2013/02/03/170851048/do-we... (although I think npr is a weird source, I don't know). In any case, those are probably just napkin calculations. And I bet I can find a wild variety of estimates for birds killed by wind turbines, too - depending on whether the person doing the estimating wants turbines to succeed or not. It seems likely they don't kill the same birds as wind turbines, either. And not in the same locations. All in all the comparison might just make not much sense to begin with. How many birds are being killed and eaten by humans, for example? Probably several billions more, but they are not the same birds that are being killed by turbines.

        Well, that's a much better reply, thank you. And yes, I agree - the numbers aren't directly comparable, but thank you for making it much clearer why.

There's a whole bunch of thread with wings attached in a fairly small radius. I would think birds can see this way better.
