In July 2014, David Brandenberger (Switzerland) toured the world on a solar bike to prevent harm to the environment. He chose a trike (recumbent tricycle) for comfort with a large trailer capable of capturing a large amount of solar energy. It also allows him to carry a lot of personal business, including his guitar and photographic equipment.
In 2016, he reached Turkey after travelling to many European countries. It is now in Australia after a 31 000 km journey!
Bravo to this tireless adventurer!
