I allude to the discussions with @dougselsam and @kitefreak during years in the Yahoo forum and now here.
These discussions are really interesting as they lead to a main AWE technological background, opposing efficiency (based on comparison with current wind turbines) and lightness (based on the point of view of the aviation). Sometimes I take informations from @dougselsam, sometimes from @kitefreak.
Their disagreement resumes the AWE difficulties, and would be still more useful if only technic contents are evoked, then explained as if it was the first time. For moderators such discussions are a challenge worth lifting.
