A new solar and battery-powered boat that can cruise for more than 18 hours: the Tesla-21
Green Dream Boats is a startup based on the Baltic coast currently developing battery-powered boats. It’s first entry is the T-21, also known as Tesla-21, a 21-feet day boat powered by a battery pack and a 4-panel solar array. The boat has a comfortable cruising speed of 12 km/h (7.5 mph) which it can maintain for 18 hours on the battery alone.
On a sunny day, the boat can be entirely powered by sunlight with its solar array.
