I couldn't wait to read more about beer delivery by drone at the OppiKoppi Music Festival. I still can't believe news of this system took so long to reach me. The video doesn't emphasize the drones enough. On the other hand, it looks like the festival will really be fun.
I learned about OppiKoppi at Slate. They cover some of the same ground I've already visited, but before they're through they introduce a company called Matternet. They envision a considerably more practical and purposeful use—drone delivery of medications and small packages in roadless areas. Stick with the video—the drones don't make their appearance until the end, after the need and the possibility has been clearly established.
I love reading about peaceful uses of drones and seeing what ingenuity and vision can imagine.
