World class adventurer, National Geographic Emerging Explorer, and a descendant of the legendary Rothschild banking family, David de Rothschild, will attempt to do what no one has done before, sail half-way around the world from California to Australia on a catamaran made 90% of recycled plastic waste powered only by the wind and the sun.

However this is not the first journey to be made across the Pacific using plastic waste. Last year a raft made of 15,000 bottles called the Junk successfully made a similar journey from California to Hawaii in 87 days in order to promote awareness of the global plastic waste problem.

Sometimes it takes an energy crisis to make us realize the value of old technology. As oil prices soar, tall wind-powered ships are looking like an increasingly viable alternative.

The first commercial cargo of French wine to be transported by sailboat in the modern era is due to arrive in Dublin this week after a six-day trip. The 108 year-old British boat, chartered by French shipping company Compagnie de Transport Maritime a la Voile (CMTV), is carrying 30,000 bottles of wine.

Though the ship travels at a top speed of eight knots— half the speed of a modern cargo vessel—it is completely pollution-free. The 50,000 other merchant ships traveling the world emit 800 million tons of carbon dioxide each year.

This 100% biodiesel-powered, 78 ft wave-piercing trimaran aims to set an around-the-world speed record while maintaining a net zero carbon footprint. The Earthrace left Sagunto, Spain, on April 27, and has already made excellent time across the Atlantic, landing in Panama just 8 days later.

Inspired by the desire to “connect with people about the need to get renewable fuels into our energy mix and to inspire them to do something,” the Earthrace has already generated a whirlwind of publicity. Much of this is due to the boat’s eco-technological appeal. It’s been described as “a rally car but for oceans”, with the ability to submerge up to 23 feet underwater while powering through the ocean. The “eco-” part doesn’t just include circling the globe on 100% biodiesel. Parts of the boat are made from a hemp-based composite, bedding foams are made from canola oil, and the operation’s total carbon footprint has been balanced by purchasing carbon credits.

Some people are prepared to go to extraordinary lengths to promote environmental alternatives, demonstrating just what is possible in a world that has long been reliant on fossil fuels.

I recently wrote of a Swiss family who are at the half way point of an epic round the world eco journey travelling only by foot, bicycle and wind power. During this journey they aim to cross seven seas and climb seven of the world’s highest mountains.

Now, a Swiss doctor is undertaking an adventure of similar proportions. Matrin Vosseler, in a bid to raise awareness on climate change has walked across much of Europe and the Middle East, sailed a solar powered boat across the Atlantic, and is now walking across the United States from West to East.

The boat has two fins that raise and lower with the tide, providing a petroleum- free alternative to motoring through doldrums.

Well, a Japanese man named Kenichi Horie is attempting to be just as environmentally friendly but without the sails.

How does he do it? With a wave-powered boat. Wave power has been discussed quite a bit recently, with a lot of applications including traditional grid energy generation. However, Kenichi is taking things to the next level by powering his ocean going vehicle with the very thing it bobs atop.

Dario and Sabine Schworer together with their two children are at the half way point of an epic round the world journey on which they aim to cross seven seas and climb seven of the world’s highest mountains, travelling only by foot, bicycle and wind power.

The family are currently in Sydney, Australia on year 7 of a 14 year expedition in which they expect to sail 70’000 nautical miles, cycle 18’000 kilometres and climb a total of 400’000 meters. They hope the expedition will “prove that great achievements can be done in harmony with nature” and have taken the opportunity to share their message with more than 21,000 school children whilst visiting schools on their route. Their own Children, Salina and Andri, were born during the expedition and continue to travel alongside their parents.
