That is an Air-X clone - originally pushed on the Blue-Water marine market, self-furling blades, umnn-hmnn... imagine being trapped on a boat with something just as opinionated fifty miles offshore in a good blow, or anchored in a little hidey hole somewhere and the unattended neighbors boats have wind jennies yakking back and forth -- before some experience built up with them a lay-in at a Marina with a whole bunch of 'em nearby made some unique memories for more than a few folks : )
Now if one was in a Yurt somewhere in Tibet... that and solar would sure beat burning lard or fat for oil light, probably also mimics the mating call of the Tibetan Ox and would keep the milk cows happy... YAK-kitty yak yak hurrrrdeeeeburrrrrrrrrrrburrrrburrrrr
