Kitesurfing (see the video below), kite buggy, and other similar AWE sports lead to a high power to space use ratio resulting from a higher density. And yet they are crosswind systems. The main difference with usually intended kite farm is the absence of figure-eight or loop, the wings going crosswind in the same direction. As a result these AWE systems can be stacked at a high density, like static kites, unlike figure-eight AWE systems which require more distance between unities.
And also the tethers are relatively short compared to the kite area. These proportions should be kept as the unities scale up as suggested on Unlock the market by shortening the tether.
