It is clear that for Dave Santos the term “SpiderMill” had a quite another meaning in 2011 (“Pairs of opposed kites orbiting a mainline”) than currently: Subscale SpiderMill R&D Progress.
From a cross wind version (figure 4) of the Laddermill we go towards a sort of generic term denoting “higher-order AWES topologies somewhat reminiscent of spiderwebs”, using the same term of “SpiderMill”, while continuing to rely on Wubbo Ockels as the reference.
