Hybrid Ships?

It may sound strange, but it's true. And a good thing too - with the shipping industry accounting for more than double the greenhouse gases of airlines.

According to a report on Lateline, a German engineer has invented a kite/sail that he calls Sky Sail, which uses wind power to reduce the fuel consumption of large ships. In optimal conditions, his invention can save up to 50% on fuel, though it is typically between 10 and 35%.


Meanwhile, back here in Australia, the people at Solar Sailor have designed ferries that use wind and solar power to reduce fuel consumption by up to 85%.
