To balance the running lines the horizontal ring needs active winching on each line
or possibly
looser downwind lines and a sag or elastic in the shaft with strong lower flying rings… not very strong stack tension sounding
back to the active winching… that’s a lot of tension, a lot of control, a lot of power, a lot of machinery, on a lot of lines for a problem which can be solved with a thrust bearing…
However… Please dispute what I say because this needs - no demands- investment in more qualified detailed scientific argument. It’s time for the politicians and wealth funds to put their money where our kids future is . I’m for 1 am sick and fed-up of waiting for their input.
Better analysis than I can give you on the difference between Daisy and Rotating reel…
