[Robotgroup] Cool NASA News - Not transparent aluminum, but transparent steel?

Even before this,
Star Trek had Transparent aluminum! Did anyone see ST4 the voyage home? 
In the film they went back in time to get two humpback whales to bring 
to the future. They needed thick Plexiglas to make the whale containers 
for the Bird of prey. So they traded the molecular composition of 
Transparent aluminum (used to make the Enterprise windows in the 23rd 
century) to the guy who owned the plastic company. I think the windows 
were mentioned in a Next Gen episode at some point.
