spray on solar windows - has anyone seen this?, page-16

Baguhn,

When Tata (then Corus) signed the agreement with DYE to develop solar steel, it wouldve ensured the contract protected its interests (ie. it got what it wanted from DYE) should the project be successful. Theres absolutely no need for it to invest in DYE. Its too simplistic to compare the Corus/Tata/DYE relationship with that of Tata/Sun Catalytix.

Im not sure how you define "a long time", but less than 9 weeks ago Tata issued a press release which included details of its project with DYE.
