This is the second edition of a concise introduction to Schauberger's life and thinking. Viktor Schauberger's knowledge of natural energies led to inventions which, if properly harnessed, could solve the world's energy crisis. Unfortunately most people still find his ideas difficult to understand or accept. Jane Cobbald first became interested in Schauberger's theories when she realized that using a copper trowel in her garden greatly increased her potato harvest. In this book, she does not aim to provide a definitive explanation of his ideas. Instead, she takes a biographical approach and teases out the different strands of his thinking, presenting them in his own words. She shows how his approach developed over the course of his eventful life (which included both World Wars) and takes the reader on a journey through his discoveries, interspersed with lively anecdotes which illustrate how his mind worked. She asks the questions Schauberger asked. What energy do trouts use to stay almost motionless in fast-flowing mountain streams, or to climb waterfalls? How does a tall tree draw the water from its roots all the way to the top? Viktor Schauberger's insights into natural energies are here explained in a clear, unassuming and entertaining way. His remarkable inventions, the author argues, could be the much-needed solutions to our energy, transport and health issues. This book includes an exclusive interview with Ingeborg Schauberger, Viktor's daughter-in-law. The text has been fully revised and updated.
