The problem with any intermittent system made continuous by having two equal systems is that each half is only being used half the time. So the second sketch represents a lot of overhead compared to eg. a traditional drag mode rig. The middle kite for instance has hardly any function.

A drag mode kite may have a ratio of production and return phase of 5:1 in time. To get zero intermittency and still have full utilization, you would need to have 6 kites in the air. Obviously the intermittency decreases anyway for each additional kite, but then complexity increases as well. Perhaps having electric smoothing of power on the ground is the better approach? Cycle intermittency would anyways be dwarfed by wind intermittency.

So with regards to having multiple units, for a given power would you rather deal with:

- a single unit with wingspan x
- two units in sync, each with wingspan \frac{1}{\sqrt{2}}
- three units each with wingspan \frac{1}{\sqrt{3}}
- …
- six units each with wingspan \frac{1}{\sqrt{6}}

Then realizing that \frac{1}{\sqrt{2}} \approx 0.71 and \frac{1}{\sqrt{6}} \approx 0.41, it seems to me that dealing with the single largest unit is probably the smallest of the proposed challenges…

Now if your rig is built to utilize the kite 50% rather than 83% (for two rather than one kite), add a factor 1.66 to the above wing areas to get the same average power…

Just saying that dealing with one kite is quite possibly the most optimal AWE topology. Or an AWE rig with all wings rotating in sync. Not many kites that need to be steered individually
