I didi it! I just made some Airborne Wind Energy. Some, not a lot :) Enjoy the first footage of a proof of concept for an Airborne Wind Energy System based on an "Open Tensegrity Shaft" (OTS). This demo uses a swivel caster with a 5" hard rubber wheel as a base that holds a bicycle dynamo hub with a power output of incredible 3W.
I will post some more details on this contraption and how I plan to scale it up during the next days. Now I need a drink.
