Wind Energy Inventing is like getting stuck in The La Brea Tar Pits

[PierreB]

I don’t think one should infer that an AWES is operational or not, by simple deduction from factors such as development location, communication, etc.

Only the technical data, ease of installation, EROI should prevail.

Regarding SkySails measured data from tests exist and are available on the pdf linked to the message below (see figure 15, average 92 kW with 12 m/s wind speed):

"Autonomous Airborne Wind Energy systems: accomplishments and challenges"

Authors: Lorenzo Fagiano, Manfred Quack, Florian Bauer, Lode Carnel, and Espen Oland Annual Review of Control, Robotics, and Autonomous Systems 2022 5:1 An interesting publication comprising features and reports of tests from different AWE architectures and companies. The figure 15 is particularly significant. Below is a pre-print:

Also old tests on similar but smaller yo-yo flexible AWES:

"Autonomous Airborne Wind Energy systems: accomplishments and challenges"

Hi Doug, I would think that some accomplishments are rather in the past. Indeed, concerning pumping power, measurements on tests were carried out. Ruppert 2012 pdf is available on the link below: https://repository.tudelft.nl/islandora/object/uuid%3A56f1aef6-f337-4224-a44e-8314e9efbe83 Table 8 page 44, dataset 5: Mutiny (25 m² kite, see page 8), 8 m/s wind speed, 5.19 kW average power, 14.1 kW average generation phase. The average cycle power / average generation phase ratio is roughly the …
