According to SoalrLab the new SolarShuttle can eliminate the production of 2.5 tons of carbon dioxide emissions every year compared to a similar sized diesel boat. The SolarShuttle can operate in all daylight conditions, stores reserve power for evening cruises and even generates surplus energy that can be fed back into the national grid. Models of the green ship already operate in Hamburg and Lake Constance in Germany as well as in Britain. The larger version has a 42 meter long hull and a maximum speed of 15 km/h with a range of 60-100 km using its internal batteries which are charged using the sun and can even be used at night.
