Aiming: 500 MW flygen by Dutch group

Re: Dr. Beaujean's Serpentine Generator Ring-
Beaujean gives a nice clue in referring to thin magnet sheets as an
enabling basis for his flying generator ring. It does seem that new super
magnets in this format really can do a lot more with less mass. Then there
is the printed thin-film motor/generator coil technology of KLD Austin. An
inflated "monorail and train" pasted with this stuff could work, with
non-contact perhaps partly maintained by an air cushion, mag-lev, or even
an oil film.
A key requirement is the close bridling of the ring to distribute tension
evenly. The wing rotors could use pulley whipple-trees to distribute their
"noisy" loads across the "fixed" bridling of the motor/gen-ring. It may be
essential to separate the lazy-susan turret structural function from the
electrical action, letting the generator elements float with faces
suspended parallel to the stress, without having to take the surge forces.
Certainly the bridles can be greatly "cleaned up" by a branching design,
so that only three main tethers to the ocean surface suffice.
Furling does seem to be an essential function not yet addressed, but it
will be. Its worth remembering that Bogey Venlo, BV, is a serious offshore
engineering firm, and Dr. Beaujean is a seasoned engineer in offshore
sector. Skysails and Makani now face yet another serious gigascale
challenge in their offshore AWES conceptual space.
Beaujean's ideas are the sort of problems that a decade or two can solve.
Its false logic Doug uses to insist something can't be done if no
prototype yet exists; like arguing in 1960 that a Moon Shot would never
happen for obvious lack of a working example.
