How much weight can a kite lift -- and flying angle and lift and stability

The problem with producing upwards I touched upon in the Laddermill thread. My conclusion is that energy is produced mostly in downwind direction. The kite would need to loop downwind for real energy production

I experimented a soft kite making small loops on Low radius loop - #7 by PierreB, the force being about 6 times the kite area (power harvesting factor), that is a value close to the maximum value which would be achieved by using a kite of which its area is as large as the swept area by the loop.

The downwind component is the same by using both static (the present lifting kite or Laddermill) and crosswind (small loops or large lemniscates) kites.
