Meet Solar Voyager: an autonomous solar boat designed to cross the Atlantic Ocean using power generated through two solar panels. The boat measures 4 feet long and one meter wide. The power system is capable of generating up to 7 kWh per day in summer and up to 3 kWh per day in winter.
This boat is satellite enabled, so it can transmit its status from almost anywhere. It has a modular design for future expansion. As the above video shows, this solar boat has always been launched.
