The news that there might be a way to make transparent aluminum -- foretold, kindof, in Star Trek IV: The Voyage Home-- has been around awhile. I was reading an article about it just now in New Scientist, and saw this quote:
"The substance itself is light-years ahead of glass," said 1st Lt. Joseph La Monica, who heads the research.
I'm sure Lt. Monica is a smart man and a great engineer (as good as Scotty?), but he needs to read my website more.
Tip o' the BA hat to Larry Kellogg for the link.
