TaaB [Tether as a Barrier]

[PierreB]

Preliminary thoughts on the crash zone were raised, especially with the third sketch, showing a dotted crash zone in addition to the in-flight location of the kite depending on its elevation angle.

But I am afraid that such (mine) estimations are still optimistic, because when the tether is broken, tether + kite can drag downwind over large distances (assuming the release tether mechanism is failing if it exists).

One way to remedy this would be to multiply the tethers for the same kite (see the SkySails nose line), at the risk of them breaking quickly one after the other. Then one way of dealing with this would be to automated kite depowering when a tether is broken.

Now the risk of crash without tether breaking would lead to other solutions.

Power to space use ratio

Crosswind kites are massively studied because they are very efficient in regard to the kite area. But as any secondary use is at least difficult under a one kilometer tether going fast with high tension and a heavy kite in the end, as a kite-farm of crosswind kites requires spacing of unities in order to avoid mess, tangle and collisions, the power to space use ratio can be very low.
