A traveling solar crêperie nourishes festival-goers while raising awareness about solar cooking

  • July 2009: Ulrich Oehler's pioneering work in the 1980s inspired a wave of Swiss solar cooking promoters. For many years, Oehler’s house in Basel even served as the country’s main solar cooker information center, maintained by the ULOG group. From 1997 to 2007, the Centre Neuchâtelois de Cuisine Solaire (CNCS) in the small town of Neuchâtel served as the country’s information hub. Visitors could see a variety of solar cooker models or ask questions of the centre’s leader, Michael Götz. In addition to this resource, ULOG group and GloboSol maintain a travelling solar crêperie in which they prepare solar pancakes for music festivals and ecology fairs throughout Switzerland. 2008 was a year of changes and new opportunities. The information center moved to a prominent location in the international city of Geneva. Götz is thrilled with the location. “Finally we have a room with a shop-window, only a few steps from Geneva’s train station!” Alain Cassani, Annick Steiner, and Yves Ronchetti of the association SOLEMYO manage the shop and information center, conduct solar cooker construction trainings, and schedule solar crêperie events, while Götz, operating as ExSol, works on consulting, education, technical development, and other projects.
