Sailing around the world on sunlight
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.”
How about collapsible windmills? If the idea is to power the boat on green electric motors small windmills could provide support / backup generation to the batteries. Probably insufficient by themselves but as an alternative generator they could keep the batteries topped up and extend non-solar range.
