Just for those who do not know
GBO = giant birefringent optics

I feel that it would be possible to reduce the weight of the film down
to about 1 tonne per/sqkm
We can also build much larger mirrors.
All we need is one mirror 1000km by 1000km and at 1 tonne per/sqkm
this is going to be 1 million tonnes.
This would probably not be practical and any damage could ruin the
whole of our shield.
I would aim for mirrors of 100km diameter requiring approx 130
mirrors to be built.
