Engineering360: "Video: Tidal energy kite powers the Faroe Islands"

I would like to understand how they deal with the twice a day tide changes, especially at the mooring electrical connection.

How are they dealing with no generation between tides, four times a day?

I wonder if that principle of increasing the speed of the water past the turbine could be used with wind in some way.

The Kite seems to me to be using a larger cross section of the water than the kite surface to get greater output from a smaller plane surface. It is like a propeller in a way, except it is not a round cross section, but a figure 8 cross section of flow
