Fox News reports that Nissan is launching a hybrid cargo ship, with 281 photovoltaic solar panels supplementing the vessel's massive diesel engines.
Most cargo ships use diesel-powered electricity generators to power the thousands of electrical devices on-board - from radar equipment to lighting to coffee makers and iPod chargers. The solar panels render the generators unnecessary, thus significantly reducing the amount of diesel fuel burned on each trip.
This innovation is in addition to more conventional energy-saving elements like LED lighting throughout its hold and living quarters, and low-friction paint for the hull.
Look for more of these kinds of efficiency gains in the shipping industry. They realize it's a sound investment, and will help us stretch our finite natural resources.
