Hi Doug, you ask for a lot. That prototypes produce about 100 kW is not bad. What more can you expect? Do you really think that many people will accept to see hyper-powerful machines flying at full speed at the end of a 1 km whip above their house, at an elevation angle of about 30 degrees, and suspended at the slightest computer fault? Maybe in Antarctica or in other desert places, maybe offshore if ships can slalom between the moving tethers…
