During many hikes in France, Italy and Switzerland I was surprised again and again by the beauty of my native country. In every season the mountains transform and show their dignity from a new side. The glaciers have melted in recent years and the changes in the mountains are dramatic. I hope that we will still be able to control climate change and that humanity will have more respect for mother nature, so that our children can still see the majesty of the glaciers with their own eyes...

Cambodia is the poorest country in southeast asia. Its people are still struggling from the civil war and the regime of the Khmer Rouge. Life in the capital Phnom Penh is slowly returning. Around the famous temples of Angkor the old traditions are still lived by the local citizens.

With the solar powered vessel Tûranor PlanetSolar we entered in the Pacific Ocean in Panama after crossing the Canal. On many thousand nautical miles we navigated westerly and finally we left the Pacific Ocean in the waters of Singapore.

In the Malacca Strait the solar powered vessel Tûranor PlanetSolar entered in the Indian Ocean. It is the first solar boat which navigated in the Indian Ocean. After crossing the Gulf of Bengal, the boat went trough Sri Lankan, Indian, Pakistan and Iranian water, before entering the Persian Gulf through the Strait of Hormuz. After a stopover in Doha and Abu Dhabi, Tûranor PlanetSolar passed the most dangerous waters in the world, Gulf of Aden, between Somalia and Yemen.

Some photo from the streets of Paris. Big cities have always lots small things to see. I tried to capture some of these small things...

Cairo is the largest city in Africa. I had the chance to visit the city just a few month after the revolution and beginning of the Arab Spring. The street life in this chaotic, laud city is unique. Driving on the road is nowhere more dangerous.

The first journey around the world begun in Monaco in the Mediterranean Sea and came to a successful end after 60000km navigation only by the sun in Monaco in spring 2012

May 4th 2012 we achieved the tour around the world only by solar energy. We showed to the world that it is possible to cross the largest, widest oceans only by solar energy. The fully solar powered vessel Tûranor PlanetSolar brought us on over 60000km around the world. I was on board for nineteen month as board engineer. If the time had allowed it, I took some shots. We visited some of the loneliest and most hidden islands in the world. We crossed storms, passed the Monsoon rain, navigate through dangerous pirate areas...only with solar power!

During a two weeks stop in Singapore, the world largest solar boat was maintained in the shipyard of Drydock's World. Tûranor PlanetSolar has been inspected from bow to stern

Through the narrow strait of Bab-el-Mandeb between Yemen and Djibouti a solar boat entered for the first time a solar boat. By navigating the MS Tûranor PlanetSolar north in direction Sues Canal, the crew discovered Sudan and Egypt.
