What I can remember about story. A man invents a material that can be made in space; It blocks 100% of the suns energy (details as to why can not remember). He decides to create a massive blanket that will in effect create a permanent solar eclipse.
At this point I am unsure if I am adding to it or if it was part of the story:
I think a hero then goes out to the blanket, gets rid of it and does away with the villain.
I can not remember who wrote it, but believe it was part of a scifi anthology as I remember reading other short stories at the same time period in my life (some 30-40 years ago).
What is the title of this work and who wrote it?
