On the other end of the wealth spectrum: this lets folks have large windows open without risking annoying bugs flying in (although birds might be more problematic). No window screen or net. Imagine the possibilities: you could install them on your porch to make later summer hours less annoying, and rather than have a bay window, you could just take out a wall.
Or you could use them to help keep poor children from dying of malaria. I'm betting on the porch, though :P
My mind instantly went to the same place. This isn't going to save a life in Africa, it's going to be used to treat the annoyance of the American middle class.
Although the ability to have large windows open with these might see the potential reduction in use of AC units. I know my AC got used a lot later in the year because screens or no screens I found I still got a dozen flies in my house over night if I kept my windows wide open.
