On October 27th, 1984, a worldwide unique decision was taken in the CO2-free, ecological Hotel Ucliva in Waltensburg, approximately 100 km north-west of St. Moritz in the south-eastern part of Grisons/Switzerland. In 1985, the world’s first solarcar race, the Tour de Sol, shall take place. With a solarcar race from the Lake of Constance to the Lake of Geneva, the power of solar energy shall be publicly proven. The initiators were convinced that solar energy is not only useful in space, but can also drive vehicles.1 The federal board of the Swiss Association for Solar
Energy unanimously agreed to the regulations of the Tour de Sol and decided that the first Tour de Sol (TdS) shall take place from June 25th to June 29th, 1985.
