There is a scientific paper on almost all AWE methods. But it is not a report.
AWE reporters (for a report) should evaluate from informations that are given by players and companies. Things could be different if they can see AWES in operation with their own eyes, and still better if some electricity production is recorded as for other energy reporters.
It is interesting to note that The no market Hypothesis (not a report as you mention) is open with @Kitewinder as the first company which marketed an AWES. Another interesting thing is its thought out of the almost complete AWE scientific community which is based from the seminal Loyd’s paper (“Crosswind Kite Power”) for ten years at least. This maybe could create a synergy towards an effective AWES.
