"If anything I think the Tata process shows how long the glass process will take, not speed the glass process up.
Serious products take serious development."

Your logic I think is seriously flawed.

Virtually no research had been done on Tin or Polymers
All the research has been done on Glass
If you look at these two Images you will see how complex DSC on Tin is compared to Glass
