I met Martin Vosseler in New York after he walked from Los Angeles to Boston in 7 1/2 months to mobilize the people about solar energy. A former doctor in Switzerland he felt the duty to inspire others and stopped his academic career. A year ago he crossed the Atlantic with a solar boat together with 4 other active scientists and adventurers. He proved that with the energy a hairdryer or a iron needs, you can run a whole boat with two electric motors, the whole technical and kitchen equipment - only with the energy of the available sun-light. After our interview he went back to Europe, but not by plane but on board of a freightliner from Miami to Italy. He said, he prefers not to use the airplane, if not absolutely necessary. In his interview he reveals all about his economical and spiritual approach to live. Watch this 18th episode of LIFE Voices!
