RE: Future for self-tinting windows looks rosy
Ms. Mahoney,
Would you specify where DOE has "called electrochromic glass more promising than the two other types of smartglass: suspended particle displays (SPD) and liquid crystal technology." I see nothing in the news release announcing the award to Sage for its electrochromic plant that says anything of the sort. Further, I find it very difficult to believe that a government agency would make such a statement--in general or in this specific case. Each of these technologies has its strengths and weaknesses, and it is simply false to claim that EC is more promising than SPD [which by the way stands for suspended particle DEVICE, not display]. For starters, SPD has a much faster switching speed, can be applied to plastic (EC cannot be), and is not limited to small surface areas, as has been a long-time problem for EC.
I think you should provide us with a direct link to DOE that supports your statement, or remove it. Also, please point out that DOE is not exactly an unbiased party in this situation, as over the years it has invested billions in EC and as a consequence has a vested interest in showing that it hasn't wasted taxpayer's money.
All three techs have their place. Why you feel the need to push one over the other is lost on me.
