Sailing around the world on sunlight

July 29, 2009

    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.

    

    Called “Planet Solar,” the futuristic-looking no-sails catamaran is being built in Germany. Domjan and d’Aboville will launch the round-the-world attempt in 2011.

    

    Domjan told CNN that he hopes the $11.5 million project will prove that boats can travel at high speed without emitting any carbon dioxide.

    

    The boat’s deck will be covered in 470 square meters of solar panels. Its skippers hope to average a speed of eight knots but can push the vessel to 14 knots (15 km/hour and 25 km/hour, respectively).

    

    The boat, in photos available online, appears to have two propellers at its stern for propulsion.

    

    To take advantage of the most sunlight possible, the tentative route is largely around the equator. In case of bad weather, batteries on board will be able to store solar energy to power the boat for three days, according to CNN.

    

    But if cloudy weather blocks the sun for longer, the boat will have trouble. Do you have any thoughts on a green back-up plan for the ambitious sailors?

Perhps they could ask these people who have been in operation for quite some time?

A green back-up plan, how about a green technique that has already proven itself for thousands of years, it doesn’t even require wind and its called rowing.

 

How about sails??

Wouldn’t a boat rigged with solar panels and sails be ideal?

We will see interesting patent infringements…
Advice to http://www.soalrsailor.com
Take a look at US Patent 5,131,341
this technology is already in public domain …

This prototype will join maneuverability and clean energy.

I am absolutely positive this futuristic-looking boat is going to work.

This is a very hot technology. Thanks for sharing. This must be spread over.

 

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.
