In addition to the large military aircraft carriers, most ships are powered by fossil fuels, and the result is environmental pollution. However, this is changing, and in the future we may rely on solar energy to travel the sea. Now, let's take a look at six creative solar boats .

The Turano is the world record holder. It successfully completed an 18-month circumnavigation of the world in 2012, and the ship has also successfully won the throne of the world's largest solar-powered ship. The $26 million solar-powered catamaran is 101 feet (30.7 meters) long and 49 feet (15 meters) wide and can carry up to 50 passengers. What drives it is the 537-square-meter solar panels that cover the hull.

The cool shape of the SeaOrbiter was created by a French architect, and a large part of the solar-powered ship is submerged, so that it can meet its long-term research and observation requirements of the ocean. The underwater structure of the boat is so ingenious that it even has a platform for divers to rest on. However, although the project has raised $388,000 within two years, the ship is still in the state of design drawings for the time being.

While most solar powered boats are big guys, there are exceptions. One of them is SolarVoyager, a low-slung boat with an entire solar roof. Right now, the ship is busy shuttling across the Atlantic. In addition, it is worth mentioning that the ship does not need to carry a crew when sailing, and the personnel responsible for remote control can also upgrade it in real time through satellite.

The concept ship, which was once only on blueprints, has begun to be built in the dock. The cost of Solaris is as high as 33 million US dollars. It uses a variety of renewable energy sources to drive navigation and achieves zero pollution. The 144-foot-long (about 44 meters) hull carries a huge solar roof. At the same time, wind turbines are also installed on board, and the cabin below deck can accommodate 10 tourists. It is reported that the ship will be officially completed in 2020.

The yacht, while not as luxurious as the Solaris, is also very conceptual. Designed by a Dutch designer, SoelCat12 is 39 feet (12 meters) long and made of lightweight, flexible materials. The ship is equipped with a total of 809 solar panels. In normal sailing mode, it can drive leisurely and quietly at sea. If you want to drive intensely, you can also turn on the two powerful electric motors on board.

Helios is also a concept product. The interior of the luxury yacht is wrapped in a strange sailboat shape, but the ordinary sails are replaced by solar panels. It is reported that the ship's "sail" will be made of 2,500 solar panels, which can produce 355kWh of clean energy. In addition, this big yacht is really long, reaching 180.5 feet (about 55 meters), and its configuration on board is extremely luxurious, and the designer even installed a cinema for it.
