Nearly 500 years ago, Ferdinand Magellan led the first expedition to sail around the world. With wind and sails, the journey was certainly a green one.

    Now a Swiss engineer wants to match the feat — with a catamaran called “Planet Solar,” powered entirely on the sun’s energy.

   

    It’s a clean-tech adventure designed by Raphael Domjan to promote solar power, energy efficiency and sustainable mobility. Domjan calls it “the path towards a lasting world.”

   

    “(I) want to show that we can change, that solutions exist and that it isn’t too late,” Domjan writes on his Web site. “Future generations are looking to us; our choices will mark the future of humanity.”

    

    Domjan — who has been an ambulance driver, mountain guide and rescue specialist — will skipper the boat with Gerard d’Aboville, who was the first person to row across the Atlantic Ocean.
