Odd.. it isn't paywalled from outside the USA.

I reckon he would be better off launching a silver plated weather
balloons into orbit to achieve the same objective with less mass.

My instinct is that it won't be as bright as he hopes.

Not paywalled here in Dk.

I believe a smooth sphere would have very poor reflective qualities compared with flat, polished facets. The reflected, virtual image of the Sun in a smoothly convex surface is very small with little intensity. While even bare glass from [say] a greenhouse roof can be blinding from miles away.

Iridium flares are caused by the reflection of sunlight off an
approximately 2 square meter polished metal surface. Here we have a
much smaller surface, but probably a bit more reflective. Seems to me
that its flares will be less than the brightest ones seen from Iridium
satellites, but maybe more eye catching because of their rapid
variation.

IMO, the whole idea is a waste.
Oh look! A pretty shiney!

What a compelling lesson it offers... teaching/reminding people about
the fragile nature of our World - NOT!

Not sure about that.
What if it gets people to look up for a few moments from their mobile phones?
They might ask themselves why the night sky is orange and appears to be falling.
It certainly wasn't that low or even that colour when they were kids.
