Just check out that video! This thing is amazing, and I want one right now. It'll probably used for unsettling things like surveillance at first, but it also has potential uses in search-and-rescue missions after disasters. As they do more work on it, it'll be able to fly for longer without running out of steam, and they're also working on a smaller version with a mere 5cm wingspan. Did I mention I want one? Because I really, really do.
