You don't need a full shadow to reduce insolation at the Earth;
a shade that appears smaller than the sun's disk, as seen from
Earth, would still reduce insolation at Earth. What you'd want
is the shade placed so that for every illuminated spot on Earth,
the shade was fully in front of the sun as seen from that spot.

I still like the billion mylar balloons at high altitude concept; it's
very simple, they can be turned out at almost nothing per balloon, and
sunrises and sunsets are going to look very wild indeed with the whole
sky full of glittering points of light.
Could you bounce microwaves off of these things for telecommunications
or OTH radar?

The new and improved L1 is actually very stable.

You folks really don't get the big picture, or even the medium
picture. You are looking at everything as though through a straw, and
at best that's a pretty damn narrow FOV.

I say; we run those full blown supercomputer simulations, then we
speak.

BTW; How many dozen of those spendy supercomputers do we own these
days?
