Part of a fleet of carbon-neutral, wind-powered sail ships planned by Britain's B9 Energy, it's just one example of how companies are looking to the past for greener alternatives to the gas-guzzling vessels that transport the world's cargo.
With the majority of world trade traveling by sea, the shipping industry is responsible for around 4% of global carbon emissions, according to the latest figures available from the United Nations.
B9 expects its 100% carbon-neutral trading ship to be in production by 2012.
B9 claims its vessel will be the first commercially produced merchant ship to harness alternative energy, but it certainly isn't alone in using old-fashioned sail boats to move goods.
