Power to space use ratio

Could be. The difference in view here is the fact that I believe a rigid wing with electric control is easier to operate than a network of passive kites. Time will show who of us, or if any of us, is right. Using rigid wings and electric control simplifies some things and makes other things difficult.

As an example, Peter Lynn spent ages figuring out the single skin pilot kite, and in his email of today, he admitted to having little to show for in terms of progress. Any way you look at it, PL is an experienced kite designer. Doing stuff when limited to simple rules (only one skin in the kite) can make the small things very difficult.

Another view: I previously worked in the seismic industry where we had a vessel towing >300 electrically controlled wing units attached to a cable (streamer). There were 8 of these streamers, with only a few meters distance, and also sometimes in two layers height. The streamers coule be kilometers long. And there would be currents coming from the side, and the vessel would turn 180 degrees now and then. We had some tangles, but mostly it was fine. And the tangles were further between the more mature the system became.

They may look like the 3D renderings of some AWE companies, but these systems were real, and quite successful.
