I've looked into it but the results, unless you live in an open field or an otherwise windy area or want to build fifty meters into the air, and unless you and your neighbors are fine with moving shadows all day every day, are disappointing. Silent vertical turbines sound cool but far outperformed by solar. Might still make sense to have a mix since batteries won't get us through the winter, but wind turbines are much better suited to fields and forests really. Even a relatively small one (so you don't need to cut down swathes of said forest for access roads and work area) has much better performance than what you'd place on a roof.
The only promising thing I found for rooftops is something that is placed on the nave of your roof (hope I'm using the right word, I mean the highest part) and the wind blowing over the surface ends up concentrating there. Should be out of sight and reasonably performant. But it was all still proof of concept stage from what I remember.
I'm curious how this project will pan out. I hope good, but the article doesn't mention what their innovation is other than proposing to put a whole array on one's roof.
