wow, that's really cool. Why is it cheaper than normal wind turbines ? Maintaining drones that take off and land autonomously sounds expensive I really like th

  They are cheaper to build because they require about two orders of magnitude less material for the upper parts, and at least one order of magnitude less foundation (for the same power generation). This saves on both building and setting it up and I would say there is pretty strong consensus on this part. You are correct however that it is less obvious that it makes sense when maintenance is factored in, but we are convinced it does. For perspective, large modern wind turbines are much more sophisticated than one might think.
