A tiny wing, even with a high glider number (lift-to-drag ratio) would have a too low Power to space use ratio when the tether length increases a lot. So both the kite area and its power, are scaling by the square of the tether length.
As a result a 20 kW yo-yo kite in the end of 70 m tether length (comprising the cable for reel-in/out, the reel-out phase time being short, about 10 seconds) would roughly become a 8 MW kite in the end of 1400 m tether length (the reel-out phase being able to be 20 times longer). But it is not for now.
Let us begin with AWES in similar proportions and dimensions as kitesurfing equipment. This perhaps would lead to a market for individual houses (10 kW range).
