Currently, the Solar Decathlon 2011 is taking place in Washington. To benefit from the experiences of the participating teams, four "Counter Entropy" – members traveled to the Villa Solar. On site, they accompany team "Calgary" from Canada, having the opportunity to work with them and asking important questions regarding the organization and construction process. Every day they document their impressions by taking photos and writing detailed protocols being immediately sent back to Aachen to the other team members. We are sure to gain important information through this participation, helping us to succeed in the planning of   the "Counter Entropy House" and preparing us for the build-up in Madrid next year.
