More than a few have embarked on an ‘around the world’ adventure, but no one had ever done so powered exclusively by the sun. Meet Louis Palmer and his home-made Solartaxi

What began as a childhood dream, to show the world the benefits of renewable energy sources and solar cars, is now an epic 18-month adventure that spans the globe. Full of surprises and apparently insurmountable obstacles, this Swiss schoolteacher’s mission begins in the summer of 2004. It is then that Louis Palmer started, with the help of sponsors and technical support, to build a solar powered car called the Solartaxi. For the technical expertise he worked together with the Hochschule für Technik und Architektur Luzern and three more Swiss universities.
After three arduous years he embarks on his solar powered RTW trip on the 2nd of July, 2007 only to get back there 18 months later after covering 54.000km through 40 countries.

Along the way, Louis and his Solartaxi meet princes, movie stars, politicians and scientists, but most importantly, he encounters ordinary people. To all of them he shows that solar energy is functional, efficient, and most importantly, reliable. A car with zero emission is not a dream. It is the new reality that he wants everyone to see and believe in!

This first ever entirely green road trip has been covered in the documentary ‘Solartaxi, around the world with the sun’ by Erik Schmitt.
