> I don't think the "plank over a ditch" is similar. If anything it's more like a suspension bridge? It’s a suspension bridge if you keep “one wire per kite”, but I mentioned that example to help make clear that the “we won’t need 1 wire for each small kite” scenario would scale the weight of the kite at a speed that’s faster than linear, and that’s not the suspension bridge scenario. I think your suggestions to modulate the surface area/adding motors or propellers/etc. also mean the larger, composite, kite would be heavier than the set of smaller kites. The structure certainly would be more complex than “just tie a thousand kites together”.
