Kite Farm test in Valkenberg

A nice presentation. It helps to increase the playback speed and enable subtitles.
Nice to see increasing days of operation.
Normally in wind energy, a numerical result of interest, for a system under an intense testing program or regular operation is kWh (kiloWatts x hours) or cumulative energy capture over time. Maybe I missed those numbers? Also wondering if there is any grid-feed? Where does the power go? Thanks.
