Some pretty amazing new technologies at this show. I was surprised to see such a wide array of design concepts. I know of a good site that has some relevant videos in regards to some of these new designs. In particular, there is an image that is in reference to the "Sky Hook" retrieval system. I'll post that video link but the site has a couple great video about UAV new battery technologies and nano drones as well.
