@kitefreak just provided interesting data about some possibilities to keep kites in the air by no wind. His message is not more available. So he is invited to post them here if he wants. Thanks.
Yep interesting indeed
Sorry Pierre and Olivier,
Recopying content here does not resolve Moderation topic-splitting and topic-changing on pretexts like “no third party reference” or “no prior reference” of new ideas and terms.
Windy Skies in fact cited your Netiquette objections as the justification to break up posting about kPower’s falsifiable claimed knot state-of-the-art to Lounge, and a lot of referenced andvanced knot content, with no one able to offer any more correct example.
