Hey Mt. Man,
I'm learning, but only from my rocking chair so far.
There are some VWAT that are inside a big cylinder with slots/vanes
that grab wind to the center no matter which direction it hits,
kinda like a squirrel cage blower on its side. Again materal/effort
vs just making another plane jane arises. Maybe if sail sheets could
be hung to collect a wall of wind from any direction to a center
turbine might merit thot in some sites. Darn it the wind moves so
much mass just in light breezes of leaves and topples em in busts
there's pony power in teasing evidence.
Looking into pulse jet rocket ventri concepts is really fun
some have a reversed trumphet looking desigsn to add thrust forward.

But it made me think that on a Vertical axis instead of just shelding
on rushing blades why not extend sheild into a scoop that redirects
air flow behind the returning blades. Least it might do is relieve
the low pressure behind the blades and at best add some ummph, noting
that it would be dumping out into the non sheilded trade wind flow
that's expected to do the lions shade of turning torque. But I don't
know if that's good or not, may just make it stall faster : (
I guess a spinaker could be set on a large dia swivel base. My picture
of it is to use a jet compressor looking multi short blade turbine
with a large dia center streamline hub to squeeze the pressure built
up into velocity. Thot maybe a truck inner tube to hold the port rigid
and act as part of venturi to a rather large patch of lower pressure
on far side of sail wind shadow. Would bright spiacker in wind be thot
of as unsightly? Would birds be attracted and sucked in ...
