The aim of the project is to expand the cooperation between the Berlin-based RLI and the Renewable and Appropriate Energy Laboratory (RAEL) at the University of California. The ERP funds will be used to increase exchanges, especially for young researchers, to better coordinate the work of the institutes, to develop research collaborations and to organize joint workshops. In addition, the funds will be used to involve other partners in Californian universities and inspire them to cooperate. Young scientists from both countries will be recruited for transatlantic cooperation and made familiar with language and cultural life.
