Europe Union launches aerogel insulation research and commercialization project

By / September 27, 2011

Credit: ARMINES/MINES ParisTech/CEP. A push like this in Europe was bound to happen sooner or later, and part of me thinks it would have been smart for the US, via the DOE, to put about $25 million of ARRA money (ah, the good old days) into something like this.  Yesterday, CORDIS, the European Community Research and…
