Hi Doug, it is about Minesto (in water), but could apply to (in air) crosswind kites.
Kites are not good converters for wind power, unlike rotating blades. This applies both underwater and in the air. However kites could be useful lifters.
In a certain sense, this is rather good news for electricity generation AWE, as it allows to focus on what might work.
Despite the criticisms that can be made (particularly regarding the required high wind speed for the MW range of the S1500), it seems that China (after Altaeros) has found a promising path with SAWES, while the parachute device does not seem to be progressing.
I also try something with torus.
