By crossing airships with airplanes, Solar Ship is creating craft that can carry heavy loads long distances with a tiny carbon footprint. Filled with helium, they soak up rays from the sun to provide the energy for forward motion and fulfill its original design challenge – carry 1,000 kilograms (2,205 lbs) of payload 1,000 kilometers (621.4 miles).
While much of the focus of carbon dioxide reduction has been placed on ground transport, it only accounts for about 20 percent of those emissions. At least as much is spewed during ocean-going shipping, and it presents another place to reduce the amount of CO2 in the air. To that end, Japanese shipping company Nippon Yusen is collaborating with Nippon Oil to develop a solar array to be mounted on a car-carrying ship. The ship is normally powered by a diesel electric system like a locomotive. Die
