My name is Helmut Tributsch and I come from a small mountain village in the Alps of Friuli, Italy. Our land is very steep and rocky. I left the place for study and work outside and became a scientist and university teacher specializing in energy research. Main interests I felt were to explore nature in its complex appearance and to reach a reasonably deep understanding of its function. Trans-disciplinary approaches for solving relevant energy problems have always fascinated me. As a consequence I have extensively worked in different branches of natural science in an international environment. Now I am back retired on my mountain farm and do reflect about what I have learned and experienced. I like to work the land and I love to feel the mountain wilderness. My approaches are “down to earth” and therefore relevant in asking critical questions. You are invited to join me in some of my thoughts and ideas on energy, nature and human civilization.
