Transparent aluminum oxide (TAlOx), a real material despite its sci-fi name, is incredibly hard and resistant to scratches, making it perfect for protective coatings on electronics, optical sensors, and solar panels. On the sci-fi show Star Trek, it is even used for starship windows and spacefaring aquariums.
I love science. The last time they were trying to figure out how to make a strong and moldable “glass” they accidentally discovered super glue.
If they can really make aluminum completely clear the applications for such a thing would be pretty wide.
